Wyetech, thoughts comments on amp.

I am presently demo'ing a atmosphere m1 amps, and compared to the bryston 7's currently in the system, the atmospheres blow the brystons away. It was like taking a burlap bag off the wilson speakers the minute the m1's were turned on. I was truly a euphoric experience. Since this will be my 3rd amp (hopefully the last). I am going to demo a few others and purchase one in about a month, being somewhat more cautious, since selling used audio at 50% is never that exciting. The name wyetech, cary, wavac, came up as possible considerations. Arc has been ruled out after a demo of them it didn't seem to offer much more than the brysons. A demo of a wyetech amp is possible if driving 5 hours each way and back again is not a problem. Some say it is worth trying. Especially the sales person, who also said atmospheres were built poorly. I live in Phila area. Presently have wison 6 (over priced) speakers. Budget 10k. Any info would be appreciated.

Philefreak:
Perhaps you should clarify which Wyetechs you're talking about. Didn't you own the Onyx amps?

The David Berning ZH270 should be on your list. It has plenty of guts, is zero-hysteresis OTL, will drive lower impedences well without an impededance matcher(transformer) like the Atma-Sphere. Sounds great, and will save you a bundle of cash. There are very few tubes since the ZOTL circuit doesn't use rows of tubes for impedance matching, and the tube life is 10-20 years of normal use. The catch is, that Berning has only about 3 dealers, and mostly works factory direct. So it is hard to find one to audition. Do a search in the archives on Berning ZH270, and you'll find lots of lively discussion and comparisons to some pretty high-dollar amps. The ZH270 is about $4500 new.

Glreno,

Yes they were the Onyx.

The Onyx is a whole different amp than the Topaz. Different output tubes, different design, different price. I have heard some negative comments about the Onyx. I didn't here that they were honky, but did hear that they were thin in the midrange and somewhat sterile sounding. Anyway, I'm not here to flame anybody about their opinions. I appreciate all comments of experiences with different equipment as long as they were done ernestly. And I've never known you to post otherwise. It's only through varied opinions that one can fairly judge what might be best for them. You may want to say what your system was at the time. That way we can all know what to avoid when system matching.
