Best wire to replace stock wiring in preamp?

Ar_t, its not my intention to get into
a street fight, and as you suggested, lets
keep it civil, which I respectfully will.
I assume from your last thread that you
were with Texas Instruments. Also, their
are questions I hope you would answer
regarding evaluations and test reports
from credible publications as to why
they make concluding statements like,
" this is the finest converter I have
heard in recent years " or similar
statements eluding to the perception
that different dacs have different sonic
characters too musical play back. Some of
these publications and their staff have
former backrounds as component designers,
degrees in electrical engineering, and
similar crudentials that are very credible
while others do not. What is their purpose
to convince audiophiles that different dacs
are better than others for musical quality.
Are they all liars? Just curious. Also,
when Matsushita years ago came out with their
1 bit mash dacs, the audio press stated that
the one bit dacs had a smoother, more laid back
quality. 1 bit dacs have a flat line sine wave
and the sine wave curve varies from one dac
design to another. Shouldn't these different
curves effect the sound quality?

The interesting question about 1 bit dacs is what happened to them. They were superior IMHO to the multi bit dacs of the time. I do think, however, that there are clear differences in dacs especially were you to compare present ones with those of old. But I must say this thread is substantially off the initial topic.

R_T, my preferred player of record--the Teac Esoteric X-01 -- employs 4 Burr Brown DACS per channel -- probably 1704. Do you have any experience with this player or its DACs and what are your opinions? KingTut, please do chime in as well--we seem to be listening to the same type of music.
My apologies to TBG and all. I realize I am further derailing this thread, but the sidebar is just too interesting!

I have never worked, or will, for TI. Matter of fact, I hate them. I make obscene gestures at their plant quite often. I know someone out in AZ who hates them as much as I do. One day, he told his new bosses that when he worked for H-P, that we went out of his way to design out TI parts.

As for Burr-Brown, they are second to AD. But as you may have read, they are now the only choice in current-out DACs. And they are not longer a true R-2R architecture. Another story for another thread. Never worked for either of them. Do not intend to. Of course, B-B is now TI, so no way in hell...........

One bit is now called delta-sigma. Actually, it always was, just that some marketing weenies thought that it sounded better. It is much easier process to make, and in pratice needs no tweaking to get the MSB trim right. The big boys love 'em, as they could build a player that needed no adjustments before it was shipped. And would sound just as good (or as bad) for as long as it lasted. But has for how it sounds........another thread is needed.

(Reminds me of a story about Sony 707ES players.......the ones with 4 MSB adjustments per channel. We need another thread just for that alone.)

I have used 1704s when I needed to replace AD1862s. I do not like the low-level linearity. Mind you, that will result in other problems, and not "as bright as screaming witch". Uses tons of current on the negative rail, as they use several ladders, fired in a carefully selected stagger, to prevent nasty current glitches on the supply.

The later series..........1738..........still have my samples on my desk.........'179x........in reality, they have a mix of '1704-style ladder DACs and some delta-sigma stuff somehow combined to give a current output. More of a DSP chip than a DAC in the sense that we think of one. Obviously, an attempt to make a less expensive chip, but retain current out capabilities so that die-hards like me will use them. They know that we are not in the market for delta-sigma.

One bit is now called Delta-Sigma? Not true. Delta-Sigma
is a modulating technique, which is actually called a
Delta-Sigma modulator. For example, Texas Instruments
makes a DAC called the PCM-1803 24 bit 96 khz Delta-Sigma
converter. So your statement " that some marketing weenies
thought that it sounded better " is false. Delta-Sigma
modulation applies to any bit DAC, whether its a 1,16,20 or
24 bit converter. Get your facts straight Ar_t!! You better
start bailing the water out of the boat.
