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?

Is, uh,...these amps you know. Is, uh, ...your amp a goer, eh? Know whatahmean, know whatahmean, nudge nudge, know whatahmean, say no more?

Tight selection of matched local feedback military grade transistors in special circuits with global power supplies.

That's good, that's good!
A nod's as good as a wink to a blind bat!

lack of global but high level of local feedback with ultra high resolution without sounding shrill

Very good, very good! Ay? Ay? Ay?
(pause)
Oooh! Ya wicked Ay! Wicked Ay! Snap snap, grin grin, wink wink, nudge nudge, say no more!

Good one Chris!
Joey: It should be the "World's Most Deadly Joke" sketch. Heheh

Nah - the most deadly "dead" joke sketch is this one.

...and now back to regular programming! (Sorry Chris I just found your initial question that does not even mention which amps you refer to ... a bit too vague - "know what I mean, Ay, Ay" )
Dave,

As talented and generous a musician as you are, I'll wager that you wouldn't mind helping Diana Krall learn to play your trumpet. ;-)
dither is sometimes used as a technique in the design of digital hardware

Indeed it is ....but our ears behave in a classic digital pattern. Tiny hair movements trigger nerve bundles that send "digital" signals to the brain. Once a nerve bundle fires off - it takes time to "reset" so it can fire again. Certain forms of dither may indeed have an impact on what we hear....our ability to hear beat frequencies that are not actually there is perhaps a product of this strange digital ear phenomenon. I think part of the way reverb works so well is that the multiple later arrivals give our ears/brain more time to analyze each instrument/sound.
Hah, I ordered "Twist of Motown" this morning, plus another Grusin album and a Ritenour.

If you don't yet have Dave Grusin's Homage to Duke then you are missing an absolute GEM!!! One of the best recordings out there bar none.
I must second both Shadorne & Dcstep... Homage To Duke is still one of the best recordings ever to my ears, and long-term reference...

It has slightly more bass then it should, IMHO, but it is the realistic dynamics that make this such a gem. To me it is this lack of compression which is what makes this so enjoyable and realistic. Piano sounds real. Drums sound real. Sadly 99.99% of music is squashed to suit the inferior playback systems in most homes and never has the dynamics that one expects of real instruments or anything remotely close to what CD's are capable of dynamically.

Harry James and his big band on Sheffield labs is another recording that has realistic dynamics. Tower of Power albums are generally all good too. Occasionally on pop music a rare piece will slip out...such as "Murder by Numbers" off the Police Synchronicity album...
Harry smokes.

Indeed he had great "sizzle"...a very nice sound and yes he did smoke (cigarettes) too...
My father played trombone in a big band that used to play during the old dance hall days. I used to play clarinet and I'm currently working on drums as you will see in my system here.
Had you considered getting a digital delay or the like to lend a sense of distance to your recordings?

And some binoculars...like at the opera! (Just kidding MrT - I do understand your desire for a real concert hall perspective and it is just as relevant as those who want Diana Krall right in their lap...)
i will leave it to the more philosophically inclined to analyze the principle of trying to accurately reproduce an inaccurate recortding, as compared to editing an inaccurate recording. in both cases, the result is inaccuracy.

MrT. You and many others are missing the point. The idea is not to reproduce a live event - that is not the goal of "accuracy". The reason for pursuing accuracy is so that you can enjoy the music as close to what the artist/producer/sound engineer intended on the media you bought. Often the intent is NOT to recreate a live realistic situation but something even more impressive and involving! Often the intent is to simply create pleasant sound and your CD (which has inherently extremely high accuracy) has already been passed through a myriad of devices and techniques to create desired effects (including deliberately added harmonics from tubes and special microphone placement and mixing techniques). Furthermore the studio which is working on the next CD of your favorite mega successful artist is probably using facilities and gear that are well into seven figures! Worse, every studio engineer is carefully selected by the artists and will put a different "spin" on the work - such as the way Daniel Lanois has heavily influenced albums such as Peter Gabriel's So, Bob Dylan's Oh Mercy and U2's All that you can't leave behind. Why would you not want to experience this work fully? Why would you not want to fully enjoy the famous "gated drum" sound invented by Hugh Padgham ( of Police fame ) and Phil Collins (even if it is not "real" in the purist sense). One of the most famous 'audiophile" albums ever - Pink Floyd's DSOTM only exists as a studio engineered product by the the band and Alan Parsons and more recently re-engineered by Guthrie.

Why then would you want to choose inferior gear that colors the sound and disguises what the studio/label originally heard and issued from their facilities?

What you are proposing is akin to going to an art gallery to enjoy seeing expensive artwork with heavily tinted eye glasses with lenses that are dirty, scratched and distorted and, on top of it, asking the gallery to dim the lights too! Perhaps you prefer everything seen with a yellow or brown tint through distorting lenses with dim lighting - a pleasant atmosphere indeed - but are you actually seeing everything the artist/producer intended - what are you missing when your speakers compress the music dynamics, roll off the bass or "BBC dip" in the midrange?

MrT. It is you and other audiophiles that are missing the point when you compare recordings to 'live music' only as a reference. The fact is the recording studio is an integral part of the overall artistic product. Reproducing realistic live music is just one particular goal of audio reproduction and I enjoy it very much too but it is not the ONLY reason.

Becuase "all audio reproduction" is inherently inaccurate compared to the real live event does not negate the usefulness of accurate audio reproduction. Would you say that accuracy in eye glasses is philosophically pointless because none are quite perfect as 20/20 vision?
Isn't Doug Sax amazing? How old is the guy? I've been looking for his name on albums forever it seems.

Indeed. Al Schmitt (double digit grammy award winning sound engineer and man behind your favorite Diana Krall sound - done with Neumann tube mics mostly) is STILL mixing on Doug Sax's original Tannoy/Mastering Lab modified speakers (~thirty years old).

Doug Sax just closed the original (absolutely famous to audiophiles) "Mastering Lab" in Hollywood a couple of weeks ago. He has moved to a new state of the art studio with Doug's choice of ATC Speakers and his brother's original designed and built tube EQ console.
