I started with Cary SLI-80 back in 2005. I loved the sound and enjoyed it for a couple years. then I realized my speakers needed more power so I went to 100w tube monoblocks. Then the tubes became an issue so I sold those and started with SS amps. Inexpensive chip amps at first then class D and I finally have an amp I really love the sound with more than enough power and excellent damping, Purify. I leave it on all the time without worry and it sounds incredible and inexpensive for the performance level, imo.
I recently heard Viva 845 SET amp at Suncoast and loved that rich tube sound, but I get tired of it after a while and prefer the clarity of lower distortion amps as long as they are still musical. I am glad to be rid of tube problems and tube anxiety.
I made the change gradually over a few years and I never dumped the previous gear before living with both the old and new side by side for a while to decide if the new is really what I want. Don’t sell a beloved amp without making sure you’re really done with it.
