Scp,
Thank you for the link. I think Spectron and this amp are two different beasts and its very difficult to compare.

ASR has battery based driver stage while Spectron's entire power suppies are highly regulated. ASR retailed for $24k in 2006, Spectron, with all upgrades, $10k now ( they have promotion now). Spectron at least twice more powerful which could be vital in some speakers and has no effect in others...

OP did not indicated the speakers he intend to use with amplifier, nor budget....

I have owned an ASR Emitter. It is an incredible amplifier - one of the best in the world if you need that much power (and if you don't, but then you are overspending). Meaning it is (at least) as pure and direct as the best 45 SET amp but with 180 (?) watts into 8 ohms instead of 2. (Although by no means does it really sound like a SET amp - it sounds better than almost all of them.)

(I currently own a Tom Evans Linear A and actually these two amps sound quite similar in many ways. I dwelled on this and came to one thing: they share the same rather odd feature of using opamps for voltage gain in the driver stange.)

Now, I have never owned or even heard a Spectron amp, *but* I have owned many class D amps of similar design. I know the Spectron is highly regarded, but if it comes anywhere near the Emitter in terms of correct tonality, noise floor, and microdynamics, I would be quite stunned.

If you really need the power of the Spectron that's a different story. But if you do need that kind of power consider new speakers. :)
