Guest Posted May 15, 2017 Share Posted May 15, 2017 You know I heard these in Perth many years ago, I am wondering if this is the same pair incredible clarity, musicality i remember listening to Carmen , and thinking it's sounded like you were there i was tempted then and now, but Canberra is long way for such big amps to send great amps GLWTS..

These would not be the same pair as I purchased these Direct from Atma-Sphere direct and never ever looked back or thought about any other amplifiers. As you say, Incredible clarity & musicality. Well these came from America with the tubes fully loaded which surprised me but Ralph (Atma CEO) assured me they would be fine and they was. Guess its not the distance, but the handling that's important. Where did you hear them in Perth I wonder?. Link to comment Share on other sites More sharing options...
Mat-with-one-t Posted May 16, 2017 Share Posted May 16, 2017 If there are indeed two sets in Perth, and they fired up at same time, they would precipitate another energy crisis like in South Australia..... Link to comment Share on other sites More sharing options...
Guest Posted May 16, 2017 Share Posted May 16, 2017 They were loaned to me by Simplyhifi from the importer who lived in Australind i had them at home for a few days in my own system although there are a lot of tubes my memory was not that they were ridiculously hot each tube only produces 15 to 20 watts class a Link to comment Share on other sites More sharing options...

Sir Triode Posted May 18, 2017 Share Posted May 18, 2017 (edited) There was a pair of M60s (I think was the model) on Ebay by a chap who lived in Jindabyne of all places a few years ago. I thought this might have been that pair, appears that it is not. So there is another pair or similar in Australia.
