anyone compared ASR emitter amp with Spectron ?

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. :)

Me too, I also never owned or even drove Ferrari but after my experience with Yugo I have difficulties to trust vehicles with internal combasion engine !

Have ever owned or even heard about Mark Levinson and Jeff Rowland, Weiss and Kharma? Be warn, some of their top models are......class "D"... Shhhhhhhhhh

Dob, have you owned either of the amps in question? Your reply suggests not yet you decided to offer an opinion anyway. I suggest mine was actually a bit more relevant.

I do own Spectron and know it rather well However, I have not owned or auditioned Emitter so I was careful enough NOT to offer any opinion or comparison of their sonic sonics - this why you did not even recognized that I know one amp at least. I did compare what I could based on the review e.g. prices, stated power etc. I think its limited, of course, but fair. Was it helpful? I will leave it to original poster and certainly not to you.

My previous post, you refer to, is just is a joke of YOUR statement [ and has nothing to do with OP] that while you did not hear specific amp in question you can make SONIC opinion based on your exprience with... other amplifiers where is only one common thing among them: class of operations.... e.g. "light trucks" You should not do it in the fuiture.
