Tube audio under $900?

I agree with Sufentanil. Anything in your $900 price range will basically be a sideways move from the 302B.

Depending on your goals for the change in amplification, you might contact Undwerwood HiFi and find out what mods they would install for your $900. It'd result in improved clarity and frequency extension...perhaps also some improved bass clarity.

Otherwise, I'd save your money until you can afford a significant upgrade.

Bottlehead and Decware. So overlooked small manufacturers with no advertising budget and stellar product.

Used cayin will give you great sound and value.b

The question came about because I have the opportunity to get the 502 for $745 and the 801 for $970. I was really testing to see if any other manufacture made better offers. Thank folks. Got lots of research to do!
