Ultra high resolution

Hi folks, I suppose this is a question none could answer appropriately. How come that some (there are to my knowledge only two of them) amplifier brands are building such ultra high resolution solid state amplifiers without having a treble that sounds shrill or piercing or artificial? It is of course proprietary info if you ask those manufacturers.
Is it because of very tight selection of matched transistors? Is it because lack of global but high level of local feedback? Is it because of the use of very expensive military grade parts? Is it because of the power supply? Is it because of the application of special circuit design? Is it because all of the above?

Ok, I just brought home my "hi rez" Rowland Continuum amp yesterday. (No wimpy tubes for me, but 1000 watts of pure sound filled the bill). The "Drum Record" will be coming off the shelf again this afternoon. (Also, that kick drum is a great way to be certain that phase is correct).

Thanks for the leads.

Hmm, I have to dig up my old GRP discs. Have not heard them in a while. Even on my low rez system years ago i remember the disc having 'good' dynamic and punchy sound...

Dave- I ordered the Tom Scott/Concord from Amazon this morning. 1000 watts/wimpy tubes? I guess I'm spoiled by the pro-practice of active bi-amping. GOTTA have tubes on top though! My room's not big enough to justify that much power($$) for my bottom. I suppose my slightly modded TransNova 9505(pretty fast slew rate/excellent damping factor: OOPS, not supposed to mention that) is putting out a little over 400wpc into the 6 ohm(nominal)Nestorovic 10"s I've got in my T.L.s(I just know the combo's flat, fast and accurate-for the sake of the thread: RESOLVED).

Nilthepill- Spiro Gyra, Acoustic Alchemy, Dave Grusin, Lee Ritenour, Mindi Abair, Gerald Albright, Jeff Golub, Al Jarreau, Joe Sample, David Sanborn, George Benson, Luther Vandross, and David Benoit are all in my collection on GRP(either MCA or Verve). Like any other label: some titles are more listenable than others, but- I've yet to be disappointed by any produced in the last few years. Dave Grusin started the label, and 'Mountain Dance' was the first album ever to be recorded fully digitally(outside of the classical genre). Did I resist? WHOOF!! But hey!! Digital technology has come a LONNNG way baby.

Hah, I ordered "Twist of Motown" this morning, plus another Grusin album and a Ritenour.

I agree with your bi-amping, but think it's guilding the lilly in many cases. My speaker crossover doesn't allow either bi-amp or bi-wire, so it's a mute point for me.

I don't really need the watts for loudness, but to control the woofers in my floorstanding speakers. I've found that the combination of high wattage and high damping factor are really needed to control the physical ringing in larger speakers and keep that all-important bass under control.
