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?

Dave- I'll bet you'd enjoy 'A Twist of Motown' on GRP(if you don't already have it). Lee Ritenour produced it(a lot of contemporary jazz greats doing a collection of motown standards). On a couple cuts the bass can get a tad heavy, but other than that it's engineered really well. Chris Botti's kickin' it on Papa Was a Rollin' Stone.

I've got several GRPs and all are well recorded. I'll order "A Twist..." next time I order CDs. I like Rit and Botti and GRP, so how can I go wrong.

One caveat Dave: If you listen at realistic SPLs, and have woofers with output in the bottom octave(20 to 40hz on CDs anyway):turn the volume down a bit for cuts #4 and #8. If the CD doesn't generate some serious toe-tappin': check your pulse!! Happy listening:)

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.
