    LST's...look what the cat dragged in....

    Oh, I do, I really completely do enjoy the assemblage of what took years to bring together! I'm not new to this sport!

    LST's...look what the cat dragged in....

    Hi Harry, it's difficult to explain the differences. Beyond the fact that both being similarly 'voiced' by the AR company, each present a different presentation almost entirely. I'm certain I must've described my impressions in numerous posts in 2014 when I bought the AR-9's. Nonetheless, to me the LST's present a cavernous like deep and wide soundstage that you can virtually look into and touch each sound or a instrument's location different and more- so than any other speaker I've heard. When listening to LSTs there's a notable sense of space around the musical tones that quickly becomes evident. Sounds emanates from and around the speaker and approaches almost as a rolling wave. Imaging can be forceful, but with-out any beaming or pin-pointing unless it's in the program source. The speakers disappear as one becomes part of a musical event and not simply sounds coming out of a box. There are often times when I experience that proverbial 'jump-factor' due to the sound's overwhelming sense of power and vast size. When a powerful crescendo or strong puck of a string or smack of a snare drum become so alive you can't help but react, the jump-factor becomes an almost involuntary response. Typically with jazz I'm at a small table 10 feet in front of a small stage with each instrument in its own position, with 'be-bop' the stage gets bigger and more spread out. With large size symphony you're feeling as though you're sitting in a large hall with a high ceiling as the LSTs project a sense of depth and size and positioning of instruments clearly defining their place in the orchestra combined with the hall's echo. With rock or pop, chest sensitizing bass notes are just as up front as a piercing guitar break. Crash and ride cymbals are clearly delineated with-in in their own space. The same on jazz hearing brushes on a snare clearly separated but still part of the whole even if only in different measure. Hearing each instrument no matter what type of music is playing while being portrayed so naturally and with equal scale is something that amazes me still to this day after almost thirty years of use. The term separation is hardly enough to describe the huge soundscape LST's effortlessly convey. FM

    LST's...look what the cat dragged in....

    Dear Liangshan Marsh, regarding the earlier woofers; if you read back a while it was mentioned by me and then confirmed RoyC that the earlier woofers have a slight bit more response in the lower registers., how slight I really couldn't tell you, however I've heard the difference as difficult as it is to discern. I do know that when I eventually had to one by one replace my woofers I decided in using the older 1970's variant as compared to the newer issues and when I read Roy's opinion, it confirmed my opinion. In terms of better sound capability; many here seem to be under the misconception that a more powerful amp is necessary only for higher volumes. Well, that's only partly correct. If you were to look at a graph you will see that doubling watts, you only add 3db more volume for every doubling of the amp's power rating. When I switched from Phase Linear PL-400's to Phase Linear Series II PL-700 I only gained those 3db more in volume which in actuality isn't all that much more in volume. However, in a nut-shell. what I did gain was the ability to better handle peak transients with greater clarity and realism and certainly more 'jump-factor'. It also permitted greater clarity for example with a 'rim-shot' on a drum. Transparency of instruments was increased because the amps were not struggling to delineate differences between those instruments and notes. In terms of bass performance, bass notes were better defined and separated between each other, ultimately sounding more real and with less doubling. To further explain; I must also mention that the amplifier wasn't the only aspect that increased transparency and better transients but, by using a cleaner-signal into the amplifier was greatly increased because my input signal from my pre-amp was being fed a cleaner source due to a more accurate signal sent by a more accurate source in there form of a costly and more accurate responding cartridge. So, in short words, the cleaner the signal from the source into the amplifier and then into the speakers all attributed to a more accurate and therefore better sounding end result. Excuse my verbosity. So, higher power is not a do all be all method and though a amp's effortless higher power is necessary to enable the signal to be cleanly heard, it's the source that ultimately matters as that's what is being amplified. In short, it's a combination of all the correct components that will lead to the end result of better fidelity. In the case of the LSTs, they require more input-power to allow each of those nine drivers to perform effortlessly to begin with. If an inadequate amount of power is applied to the LST, that's asking the lower power amp to work harder and at some point even being stressed. By stressing an amplifier to attempt to cleanly move all of those nine drivers, we introduce a degree of distortion/clipping and ultimately listener fatigue. In my world, I learned this four decades ago with my AR-3a's powered by a 60WPC amp that just didn't sound realistic and had limited response in terms of accurate or real sounding instrument portrayal. When in 1974 I became hungry for more realism and accuracy out of my system, I then switched to a 400WPC @ 4 ohms PL-400 and fell in love with my system all over again and never dreamed of going back to a canned reproduction or lesser sound. It should be known that higher amplifier power comes with it's own set of rules also. To use the 'car-analogy', one buys a higher power motor for smoothness and safer acceleration when passing but, one does not always drive at high speeds or tear away from a traffic light with that added power, it's just smoother, safer and faster and certainly confidence inspiring. I have a few videos using a single set of LST's with a PL-400 and the LST's sound terrific with most types of music, however when I installed a PL-700 Series II amp it seemed as though a new world of detail, transparency, and realism had opened up to my ears. I don't post videos because as with a sound-clip on a computer set of speakers, the differences are barely discernible so, I don't bother. Regarding my choice of amplifiers; these old-birds are not for every one. A newer amp from "Parasound" or similar name brand quality may be recommended. I remained with Phase Linear because of my history in using them. Back in the 1970's I felt as I do today, they just have a clearer top and bottom end that I easily grew to enjoy and continue to enjoy today. If you were to decide on the Phase Linear, I'd recommend a DC-cut-out relay' installed along with a complete new set of matched higher 'SOA' power transistors along with a replacement of any needy capacitors and resistors on the driver-broad. This would generally apply to almost any 45+ year old amplifier in the same way. Speaking of my own opinions: I find many other amplifiers just don't have the iron-fisted and well-controlled bass-slam or ultra-extended high-frequency response that the old Phase Linear's do in their price range, especially with deficient speakers as AR's. In my travels, I've found the Adcoms a touch lacking in the higher frequency areas sort of like I've found my B&K ST-202 to be. That 202 was simply a mess sorting out the different frequencies and was completely lacking any balls in the bass with an absence of real-guts across the entire frequency band. FM P.S. I would consult the "AR-Guide" to understand the different periods of the famed AR 12" woofers. Like I said, I prefer the circa 1972 to 1976 variety, which of course would be period-correct for the AR-LST as it is for my three pairs of AR-3as.

    LST's...look what the cat dragged in....

    @Liangshan Marsh, a very good purchase you made indeed however, it looks as though those woofers are not the original ones as they look like newer AR-9 type woofers. Even though they will work, if you want completely original you might consider changing them. According to my long term use of LST's, none of the amps you mention will ever be sufficient to drive those speakers to what they really need to sound their ultimate best. I went from 400WPC to 700WPC to fully appreciate what these speakers are capable of and although I enjoy limitless distortion free transient-peaks, I feel they are capable of handling more. Julian Hirsch of "Stereo Review" felt that they could use more than 700WPC in his 1972 test report. He was using the same basic amp as I am, a Phase Linear PL-700.

    Kind of weird AR 3a amp question

    Could you guys elaborate, further explain your personal perceptions about the sound quality of these amplifiers?

    Just bought my 2nd pair of AR9

    No, it's not my set-up, though I did post that foto here a couple of years ago, I swiped it from the web. I will say that even though those speakers shown are the Mark Levinson version of the "LST", I can say they are not situated/placed in the room correctly as the LST type cabinet lends itself self better against a wall. The foto appears to be in a foto or TV -studio due to the high blacked-out ceilings, large doors and high thick black curtains. I feel this set-up's output is getting lost in that room. LST's were designed and intended to utilize front-wall reinforcement. Almost anyone can buy expensive speakers but, it doesn't necessarily mean they know how to place them correctly. In 2013 when I first brought my LST's into their new intended room, I tested a single pair in different locations. Using the one-third principal placing them 1/3 into the room while using different height stands, they sounded dead and with-out any of their true potential sound being realized. Instead of them eating up the room, the 13' X 26' X8' heavily cushioned room swallowed them up.The heavy rug, a thickly padded couch and two thick armchairs that were close to them soaked up much sound. Most speakers generally need some degree of room/wall reinforcement unless they're designed not to. Whereas all AR classic-era speakers will benefit from room and wall or shelf acoustic reinforcement, doing so is necessary for maximum listening enjoyment. For me, even though I can replicate a similar set-up to the one shown above, I'm still fearful of mounting another set on top of my double set even though the stands I use can easily handle the weight of 270lbs. per -side. And, as I've learned in my 31 year span of ownership, when I blow a fuse, it's always been an issue to swivel one or both speakers on their stands I use to get to that fuse. Changing fuses on three stacked 90 lb. speakers would be outright dangerous. You can tell "ARsurround" I said that. When I moved the speakers closer to the front wall, they sounded as they were designed to sound. I placed them closer still about, 3 inches from the wall to allow fuse access. They sounded much better and closer to how they were designed to sound permitting their fullness of presentation to be fully heard. I had utilized similar placement in the two other houses and apartments I once had them in prior to this final location. This last location/room is rectangular a therefore is virtually ideal as a listening room. I have placed 'bass-traps in the upper front wall corners to prevent a barely noticeable form of congestion that was occurring at the ceiling corners. Doing so, allowed for more transparency of mid and lower bass frequencies, and by doing this, the typically bass-rich AR speakers didn't suffer because of using this frequency manipulation and absorption. I plan on using more absorption/traps in the corners of the 'rear' wall also however, at this juncture my listening room is almost completely dialed-in and over-all is sounding superb and is my best 'set-up' thus far in over 45+ years of enjoying high-fidelity.

    David, so then, you are pretty much well situated.

    Just bought my 2nd pair of AR9

    Don't despair David for there is a pair in good shape in Maryland on the auction site is 2 grand. That's about a 7 hour drive as the crow flies from MA. When I found mine in early 2015, I was lucky that they were only 45 minutes away. I wrapped each one in a moving-blanket, used much packing tape to hold the blankets in place and because rain was a threat that morning, I wrapped each one in two large black garbage bags each as protection. My helper and I carefully lifted each one on its back and laid them both in a pick-up truck. Got home and tied each one to a hand-truck to get them into the house. Should you buy a pair and have to pick them up, it is a mandatory two man job or damage could easily occur with their 130lb. dead-weight each. Moving blankets are highly advised with plenty of the 2 inch plastic packing tape. Although, over-all I prefer my four LST's, I must admit, the 9's are excellent but, project differently. P.S. There's also a nice pair of LST's for the same price in N.Carolina. I have found that after enjoying AR's larger speakers with very large amplifiers, I can't see myself ever going back to the 3a's or 2ax's. How could anyone? Good luck.

    Calling Frank Marsi

    7-27-18 A-hoy, who goes there……. Don’t shoot, it is I……… David it is I. I’ve been busy getting back into my music collection and haven’t been spending too much time on the web. Those LST 2’s would easily fit into a room in the late sixties or early 70’s but are just too out of place these days unless your room is ‘retro’. And, it is very true that my main passion and attraction is only for 12 inch woofer equipped speakers. Although, I’ve lately been getting back into playing my bass guitar again, I first had to have my Bassman amp refurbished. It has two 15 inch speakers and still puts out well enough. I also find it amazing how playing guitar has been elevated to new heights by the newer generations and styles of playing, especially for me to see since I use to play 45 years ago. The amplifier was slightly modified from 50 watts to 70 and seems to put-out a touch more. In the guitar amp-world, tubes have their place however, replacing tubes is costly, as I shelled-out recently but, I always knew this is the cost of admission. Using two 15 inch speakers directly as in using a musical instrument amplifier still reinforces my long held beliefs about using 12 inch woofers as the ultimate size woofers for home stereo use. I find for home stereo use, 10 inch woofers try to satisfy but, just don’t have the where with-all, 8 inch woofers are simply inadequate, and 15 inch woofers just too lumbering and slow. Other than that, my system is still impressing me every time I listen to it, and using my newly acquired vintage tone-arms has been very satisfying all around as I’m glad for the choices I’ve made. My latest favorites are the two “Dynavector DV-505” arms I waited to find in mint condition. What befuddles me is so many folks here are so into their vintage AR speakers but, insist that CD (a relatively more modern ‘input-source’) is the way to go. I feel, if you’re going to be a stickler about vintage speakers what the heck are you doing with CD’s or silly downloads? Clearly the counter-part of vintage speakers is using LP’s. My only exception, is using high-end modern phono-cartridges as the older cartridges simply cannot compare to the new designed cartridges that I use. And, it can’t be realized until one focuses on the vinyl front-end and makes the change to upgrade to better that input-source in order to ultimately realize how wonderfully cared for vinyl records and an upgraded table, tonearm and cartridge make. It’s odd how folks here insist on using old and on their last legs speakers and yet feed them CDs. To me, that’s not a complete dedication to the vintage realm but, is only going half way. Not using vinyl is missing out on a whole lot of fun. A quality and well set-up vinyl rig is certainly more complete and affords more musical satisfaction over-all.

    What type of load is the AR10Pi ?

    Thanks for the clarification gene. I sort of knew the answer but, it's not good to answer a question when one is not fully sure of the answer. I'm sure DavidR will work it out. FM

    What type of load is the AR10Pi ?

    I felt it was useful information on a few different levels and I spent the time searching for it as common courtesy but, so what, the culture has changed, rite? AFAIK common AR knowledge says that AR included ferro-fluid with their AR-9 and no doubt also with the AR-11 and 10Pi in the new series. I run AR-LST's with an even bigger transformer in the X-over along with nine multiple drivers in each cabinet and never experienced any grief because of it while using transistors. Tubes may not be that different. I don't recall ever hearing folks complaining of difficulties as many folks were still using tubes when the AR-11 variant was released. I believe if you're using a fuse as you should, a blown fuse or 'open' would create problems for tubes. A good web-search with time will probably offer more info to you.

    Diseases can spread easily especially a nasty one.

    AR-XA in box?

    der, and what do you mean? Pete B., DavidR, tysontom and I have all been discussing audio here. Maybe not your audio but, audio just the same. Snarky or 'drive-by' divisive incendiary comments as it were with one sentence remarks is not discussing audio either and make no clear point. Flippant shouts from the bleacher seats are not constructive and add nothing to the dialog here which iincidentally originated about a box with the possibility of a turntable in it. Not about audio complete;y but, about a device that is used to make an audio signal. FM

    AR-XA in box?

    'as little to do with audio as one could possibly imagine'. What do you mean? Regarding Joni, I have many disks she's recorded, on vinyl, of course. I consider her one of the more unique and creative female singer/song writers around and have been a fan since mid 1968. Sadly, a few months ago it was reported that she wasn't doing too well. I never heard the follow-up. She's an extraordinary songstress and multi-talented. FM
