Looks like there's some serious interest from the "big boys."

How do you justify 1100$ for a 30$ amp chip? Thats one expensive box.

Yes, it is a little expensive for a $30 chip. However, what would a 300wpc tube amp cost?!?!?!?Colin

Point taken. In AudioeXpress this month, Norman Thagard has parralled 8 Citation 11 tube amps for 480 watts out. What a sight, the whole set-up weighs over 500 lbs.

I've always enjoyed Dr. Thagard's articles. His amps are always so over the top. My aX has not shown up yet. This article along with the Tand Bang project should make for some good reading. Do you ever look at Tech Talk at Parts Express' site? Those boys are all over TB projects......Colin

No I will have to check them out. In the article they do some radical stuff such as using a heating iron to dimple the cone. Thagard is something else ain't he? I hold him up to my son as an inspiration.

Some reasons why SETs sound different [message #10823 is a reply to message #10805] Wed, 08 December 2004 13:52 Go to previous messageGo to next message

HI John & everyone else,
Good post! Here are my 2 cents:
An amplifier should sound different if it offers:
a) a non flat frequency curve
b) appreciable distortion (over 5% to be audible with music)
c) High output impedance, in other words, low damping factor.

Most solid state amps today, even the el-cheapo ones, are pretty much dead flat freq curves, non audible distortion (below 1% usually) and have very low output impedances, along with very high input impedances.

Tube amps: ahhh...they are all different. For example, I did a review of the Stoetkit Jr with the Zen se84c, and the zen se84c seemed a lot clearer, probably becuase it emphasized the midrange more (in other words, not a flat freq curve). Usually, SETs have higher (much higher) distortion than even push pull tube amps, and as they clip this sound can be liekd by some people (esp. guitar players!). Finally, having a low damping factor can artificially increase the bass in single driver speakers, esp. with heavier cones. That is why these speakers sound better with SETs than SS amps.

Which offers greater "fidelity"? I think SS amps for sure. Which is more fun to play with, as long as you don;t care about fidelity, but just want to have fun and listen to music? Tube amps, esp. SETs!

My 2 cents.FYI, I own 3 SETs: one zen se84c, one asusa (el 84 with 12ax7 drivers) and one classic SET 45 tubed (the one I listen to most, and the one that probably measures the worst!)
I also have a solid state Yamaha amp I just bought from the late 1970's: sounds great but no character: kinda like buying a HOnda versus an old MG roadster, if you know what I mean!
