  1. dynaco stacking issues

    ebay prices are all over the place, I'm in northern Ontario Canada, north bay. This older stuff is hard to find up here and depending on equipment it can be very expensive.Check out this site\\Kijiji.ca, go to Ontario, there is alwys a few sets for sale usually around 200.00 to 250.00 Canadian, but I think shipping would kill....Peter
  2. dynaco stacking issues

    All good now, raised stands 2 inches, new 1 inc isolation pads between speakers and stands, sound fantastic now, even put in a 10 inch powered sub and very close to what I was thinking this set up should sound like..Any idea what I could get for a very nice set of a25 with old cloth in good shape and new grills done, thinking I don't need 3 pairs...Peter
  3. dynaco stacking issues

    Well I found what I think was a ground issue between my components, there was a very slight hum to the speakers, that was amplified at higher volumes.I ran copper chasis grounds from and to each component and this seems to help conciderably. Now to build higher and heavier stands and see what that does . Looking for a st70, or pair mark 111 monoblocks, and move the Marantz upstairs with other pair of a25. Time to get the tools out, good day for it as its snowing like crazy outside...Cheers and thanks...Peter ill keep ya posted
  4. dynaco stacking issues

    no boomy bass with only 2, I have 3 pairs and have tried all kinds of combos, I uusually pull speakers away from walls when I play lps, cd etc.But there is no change in sound when stacked. Last night I tried stacked with a set of taller homemade stands , about 16 inches tall and the boomy bass was gone, thinking the smaller stands also homemade were causing bass from bottom speaker to bounce off hardwood floor.But doesn't when only one speaker on small stand. Kinda got me baffled, pardon the pun. Havind stacked on tall stands kinda unsafe,and not to sturdy, don't want granddaughter knocking them over. Just have to keep trying I guess. .Furniture is 2 large leather couches sitting on gig area rug, back wall is treted with home made accustic panals,all glass are covered with heavy linded drapes, room is 22x 26.stands have foam strps on bottom for isolation, and there is a thin isolation mat between speakers. I sealed all drivers when I recapped, resealed the cabinets as well, figured with them being so old that they may have dried out and wood glue may have failed, that helped tremeandisly in sound. Going to go through all my interconnects today, gotta try to figure this out. Thanks for reply, and sorry about spelling,,,Peter
