Over the course of 50 years in this hobby have heard or owned or near owned damn near all the high end amplifiers produced. Such as Levinson, Threshold, Krell, Classe, Coda and many others to numerous to menetion here. But when it comes to Class A ampd I have always gravitated back to the Nelson Pass Threshold and Pass Labs units. At present I do not have a Pass unit in the system. Moving shortly to the X350.5 in a few months. Now running a PS Audio HCA 2 Class D amp. Very happy with it, but no where near the level of the X350.5 While it is not a pure class A amp such as the Aleph series, it delivers the signature I want, with less heat and drain on the power bill.
As far as Levinson and Krell go I have never kept any of them longer than 3 months. Impressive at first, but in the long run just have not pleased my ear.
As far as tubes go, when I got into this hobby that was all there was and mono to boot. So from 1957 to 1977 was in the tube camp until the Threshold gear came out. Dumped the tube gear in 1977 and haven't looked back. Twenty years of fiddling with tube gear was entirely enough for me. And that was during a time when you could buy new good tubes made in U.S. or great tubes from Europe. I have heard the Russian and Chinese tubes, to me pure junk as opposed to what we had in the tube era.
One of the great Class A/AB amplifiers I have heard recently was the Musical Design D150B signature unit. Now thats one Class A/AB amps I could live with nicely and totally recommend.
