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?

Oh man, you made the sale for sure.

Have I mentioned "Cannon Reloaded", an all star tribute to Cannonball Adderley on ConcordJazz? It's got Tom Scott and Terence Blanchard among others, but most impressive for me is Marcus Miller on electric bass. The bass is slammin' good.

I'll find one today Dave! Nathan East plays on 5 of the 11 cuts on "Twist"- need I say more? I do believe we've hijacked a thread Dave. Sorry y'all!! Then again- Your bottom has to be resolved as well to hear everything that's going on down there, and avoid(what I call), "one note bass". That's when you can't tell one note(pitch) from another on the bass instruments, or: the kick-drummer from the bass player when they're following the same bass lines(the sounds just blend together). A good test of your amps/systems bass resolution is the HDCD(RCA Victor) soundtrack of 'The Thin Red Line'. See if you can tell the two bass drums apart on track 3(one played with soft mallets, the other with hard), or hear the ambient air around the bass instruments in tracks 6 & 7. I'm not excited about the music, but it's a great test along with the Sheffield Labs Drum Record. All of the above are realities in live listening(from any perspective in any decent venue), and will be "there" with a resolving system as well.

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).
