The Juicy Music Audio tube gear is great (preamps and power amps), but it is pricey if you can't find it used. A fairly new company with a long history behind the owner. NOSValves power amps, his VRDs rock great too. Made in Michigan. Again, pricey for the new and uninitiated.
What kind of music do you listen to? How loud do you want it? CDs only, or is vinyl in the mix as well? Room size? All these can make a difference on what we would recommend. You into home theater? That would change the game plan a bit.
Other used tube gear would be HH Scott, Fisher, Dynaco. Do you have a specific budget to work from?
