Advice Needed - amp for Large Advents
Posted 18 January 2012 - 04:48 PM
I have a system which includes 4 New Large Advents. My power amp is in the process of dying so I am looking for a replacement.
Does any have suggestions either in terms of currently available, new units, or a source for an approprite used unit?
I had a Soundcraftsmen PM 860 for about 13 years which I was quite satisfied with.
Thanks for your time!

Ran across a Rotel 980BX in Cambridge MA. Any thoughts on the appropriateness of that amp?

If so, then then it would be a 4 OHM load on each channel.

However, from extensive reading on the subject, it seems there are some amps that would fill the requirement.
Aragon 4004 - come up regurlarly on Audiogon for well under $1000. Can easliy handle a 4 Ohm load.
Aragon 8088BB - also come up occaisionally on Audiogon for about $1200. Can easliy handle a 4 Ohm load. My buddy has one, I've heard it many times and it is a great amp!
Adcom GFA555 & ADCOM GFA555II - are good at 4 Ohms and are readily available on EBay or Audiogon from $300-450.
If you wish to go new, then maybe the Emotiva XPA-2 would be a good choice. Plenty of power and nothing but great write-ups.
They should be running a sale this summer but right now it sells for $799. It also has a 5 year warranty. If I needed an amp right now, I would be looking at the Emotiva XPA-2.
These are all suggestions and I admit that I have never even heard a stacked Advent setup. But at least I'm trying to help.
Anyone have better suggestions, please, please chime in.

If the Crown DC-300 or A is original then a re-capping and re & re some resistors may be in near order.
It was a battleship way back when but the technology is old and local servicing may now be difficult.
I agree that it was and still is a terrific sounding amp, actually not sounding but performing amplifier.
Within it's capabilities it does get those woofers cleanly pumping the deep bass.
Tom Tyson has posted information regarding a $300.00 Crown amp here a few times, his advice, without question, is always well worth considering.

When I had my stacked advents I had an ar amp. It was designed for the 4 ohm load of the 3 etc. I worked super on the advents as it was rated at 60 watts per channel into 4 ohms. there are afew on ebay and one is completely restored and guaranteed. I would really look into that.
I have owned an AR amplifier and tuner since new around 1970.
At this time, if I knew I could get an AR amp, tuner or receiver competently serviced locally I may also recommend them for purchase.
From some of the issues that I have read about I cannot recommend buying these units.
I would suggest that a more currently made amplifier or integrated amplifier or receiver be bought, such as the Crown for $300.00.
Newly made and waranteed by a well known manufacturer.
Just my thought for today.

What is your reason for not using a restored AR amp? My filter caps went out after about 10 years but ar replaced them for me with some high quality new ones and it worked fine and the guy I sold it to still has it (2012) and it still works fine. Can;t beat that recored. Personaly I would stay clear of any tube amp as there is just too much to go wrong in them plus trying to find new tubes that are good and matched.
Your point of not buying a tube amp is the same, except AR used transistors, not tubes.
When the original manufacturer of equipment is still in business chances are much better of getting OEM parts than when they are gone.
I have 2nd hand information that when AR moved from Mass to their newer location there was no setup for manufacturing my AR tuner, etc, thus the scarcety of parts support thereon began.
Such as the simple part, an internal tuner pilot lights which can be substituted with something close but is labour intensive.
The original AR amp used a red bezel neon enclosed pilot light, a suitable substitute is still available as a longer bodied neon, by adding a suitable power resistor an LED bodied lamp can be used instead.
If you read the AR amp/tuner/receiver service manual posted on this site you will easliy see what parts are difficult at best and near impossible to find or even have suitable substitutes, today.
Unfortunately we have lost the vast transistor selection of old and even substitutes are getting difficult to find, at a reasonable cost.
For the suggested Crown amp for $300.00 U$ it is hard to get a qualified and competant service tech to service a dead AR amp, and other electronics today, parts and labour.
I have not been anything less than pleased with all of my AR electronics, since new, but as they get older the likelyhood of a fatality is a for sure thing.
Even Dynaco did not make their solid state electronics with stock drop in devices all the time, even something so simple as a bass and treble was custom ordered.
I am positive that more than person here knows of a past brand that used standard, off the shelf components, rather than special spec'd parts.

Thanks to Stan for his link to that amplifier.
I just returned from there and here are my thoughts.
Nice looking equipment to my eyes.
They do not suggest using loads below 4 ohms, as heat build up and safety circuitry may kick in.
They do include in their owners manual, an extensive manual I might add, parallel speaker load wiring and their suggestions.
What I would suggest is that an anticipated speaker load of 2 ohms be considered, not long term but at least short term.
