Glad they're working for you. $900 seems like quite a bargain. Years ago I had a pair of Blue Circle BC-2s which are also class A single ended solid-state. They sounded glorious, very organic, wonderful on vocals. Not a lot of punch, though. They could raise the temperature in my room 15° easy, you wouldn't dare touch them.
Valvet E1R Mono Amps
Just picked up a pair of these this morning from jimndre. Great transaction and he is a true gentlemen! Very easy to work with. It took a while to get everything set up but I've been listening to them now for about 2 hours. They haven't been played in a while so I suspect it will take a couple days before they fully open up. First impressions frankly have me floored. They are so smooth & uncolored, or in reviewer speak... organic. When I say smooth I'm not saying the top end is rolled off either, its not. So far they sound "right". For those not familiar with this product, these are single ended 10 watt solid state mono amps. They are also little space heaters :-), although I doubt they run much hotter than the tube amps I've run in the system prior to this. I'm not going to compare the sound of the prior tube amps to these yet, but will after I get more familiar with them. BTW they are driving Lowther speakers. The pre & phono amps are tube powered.
