I am really curious about the new Tru Coppers.
They are really amazing. I was reading up on them, but I can't remember where I read it now. I think it was an Australian forum. The most surprising was the one with no pre-amp. I'm not sure how it would work unless you had a line driver which kinda defeats the purpose of not having a pre-amp stage. I wonder what the input sensitivity is on it.

I always wanted to get my mits on some of the Phass RE series amps.

Would you guys consider The Alpine PDX amps to be SQ?

With enough attitude, yes!

This one time, in a make believe land far far away, I asked a simple question: what is "high end" defined?? Never got my answer and probably never will..........:crap:

Also, don't tell Tristan too much...or else he'll just buy them and make us jealous.

Definitely check out the TRU amps. I have a Billet and a Hammer and love both of them.

I'm pretty sure the newest Billet line is made in two different versions. One without pre-amp controls and it also has RJ45/CAT cable inputs instead of RCA inputs.

I was reading the manual for the new Billets (I requested a copy from TRU since they are not available online) and they have a bypass feature for the preamp. I don't think there are 2 different versions of the amp. Its just a switch on the amp that will bypass the preamp stage.

The new Coppers come in three configurations: tube pre-amp, no pre-amp, and traditional BB pre-amp.

Hmm,

I would define a high-end amp to be application specific:

Anything full-range, above 85db S/N with a damping factor > 50 at it's lowest rated ohm load and has just a bit more unclipped power than necessary to drive your speaker to it's mechanical or thermal limits.

How's that?

Yes, my Billet is like that, but the newest version..............there are two. The "AD" version and the "S" version and they are distinctly different. I talked with John Yi about one time, but I can't recall all the details.

That doesn't make any sense at all! That description would include pretty much all amps.
Yes. Pull your 2x100rms amp out and put in a huge 2000w (2x100rms actual) pyramid and have someone blind test it.

Actually I have seen some issues in really cheap amps like the gain being off and one channel was more powerful than the other. Power ratings are always suspect, and they break faster....but far as sound SQ you will have a hard time proving it. They might have a different response even, but still usually 1 db, maybe a little weak in the lowest bass (so they can eek a little higher power rating), even then everyone has EQs and its likely less a problem then in the past.

"A bit more" is a vague statement and highly debated topic on this forum that I still don't quite understand. On one end you have the minimalists that say you only use xx watts while listening to music so you don't need much more than that. Then there's the extremists that say there's never enough power and headroom is important so running 150W midbasses off a 400W/ch amp is the minimum you should have.

I've actually gone both way. In the old days I had a Soundstream Granite 60.2 running tri-mode for 30w to a pair of Boston Rally components and 100W to a JL10W1 and it sounded pretty damn good. Then I had a TRU T03-4.150 running active MB Quart mids and tweeters with 150W each and a Hammer sending 1500W to a DD9510. I'm sure I never even used half that power since my main ckt bkr was rated for only about 60% of the max current draw of both amps and never tripped. For my next system I'm going back to the minimalist approach. 50W/ch for active mids and tweeters and 250W per sub.

Mcintosh amps are considered high end also.
