Good sound is good sound regardless of where it's made. I had a 6.8 watt Nobsound amp that I bought for $235 to use while I was rebuilding my Dynaco 70s with the VTA mods. It was surprisingly good. Not as good as my VTA modded Dynas, but I was still impressed with the value. Changing tubes can vary the sound, and is part of the fun. Listen to as many as you can, and buy what you love. You only need to please yourself.
I'd also highly recommend looking into the VTA amps from Tubes4Hifi.com. I think they represent extraordinary performance at an affordable price.
