Here is another "make your own incredible tube amplifier" from a Dutch gentleman. I'd be interested to hear from someone who understands this stuff, how it compares. http://www.mennovanderveen.nl/eng/index.html http://www.mennovanderveen.nl/eng/index.html Also, I'd like to hear for myself how they both compare to the $20 solid state amps. http://www.amazon.com/exec/obidos/ASIN/B0049P6OTI/downandoutint-20 http://www.amazon.com/exec/obidos/ASIN/B0049P6OTI/downandout...

As a piece of performance art, they are polar opposites. One is a craftsmanship project hand built according to some peculiar rules (pre 1970s tech when possible, etc) and methodically designed to optimize performance and then tested to verify that performance. The $30 amazon mass produced amp ships with a 1.5 amp power supply that was restickered to 2 amps (hope your fire insurance is paid up) and can't provide marketed power with the supply as provided anyway depending on speaker impedance connected and no one has any detailed performance stats so who knows how well it compares in all the parameters that matter. Also it runs about 1/10th the power of the tube amp. Finally it is a class D amp but the chip mfgr went all closed source on making a "special" D that got patented as "T", the "T" designator is merely marketing. Its a relatively early class D amp, I would assume modern class D amps would outperform it. Note that both amps are antique in their own way, one is a "70s amp" and the other is a "turn of the century amp". As a piece of art, one is roughly a highly talented semi-pro artist classic inspired painting, and the other is a walmart poster copy of a "Dale Earnhardt on black velvet" memorial mass produced kitsch, should be pretty obvious which is which.
