In Reply to: Oversampling posted by Rodney Gold on March 30, 2000 at 07:51:55:
Actually, his statements have to do with sonics. Read Haute Fidelite's review of the DAC5 (they called it the best they've ever heard - the first DAC that outshines analog) and Hi Fi News & Review's review (they said measurements suck, don't know wht it works, but sound is amazing).Have you listened to it before making these comments??? Like the Hi Fi News review says, they had to throw out all their previously held views on digital design when they heard the DAC5.
By the way, I have the DAC 1.1. It's not in the league of the DAC 4 or 5 obviously, but is really very natural sounding. I use the Sakura Flatfish as a transport. Previously I used the Anthem CD player and later the top Sonic Frontiers. The Flatfish used as a CD player blows away both hands down. No glare, very full detailed rich sound, deepest bass from CD I've heard, extremely natural. The standard DAC 1.1 isn't really a useful improvement over that, but I upgraded it by changing all the 1 watt metal film resistors to either Tants or Rikens, all the Digi board and Analog board caps (except the Wimas) to Black Gates, and the power supply caps to Black Gates and resistors to Mills or Yamamuras. Tremendous lowering of the noise floor, increase in ambience, naturalness and tone, and effortlessness.

Thanks for the updates. i, too, am going to be going the way of Black Gate, silver wire, and other tweaks. Aaahhhh, the next level in getting the most from this kit. :-{)
Enjoy the music,

To completely blow you away, after changing to Black Gates, tants and rikens, hexfreds, etc.. I changed the tube from 12AU7 to E80CC - a complete shocker. Increase in bloom, bass and dynamics is devastating. Next to go is the power supply, one of the weak links in this kit, maybe later - transformer coupled filtering a la DAC 5.Lastly, Black Diamond cones really help -
Have fun!

Oooh, i have one of those tubes here somewhere (as i start scratching my head trying to remember which storage space they are at). Just found a pair of 5814. Hmm, maybe i'll try those too. Have you tried the 5814 yet???
> > > Increase in bloom, bass and dynamics is devastating. < < <i agree the overall very large scale dynamics could use some enhancement. i LOVE the micro dynamics and analogue-like ease i am currently getting.

Yes, tried Tungsol 5814A's (a very good tube) and it was better than 12AU7's - but nothing compared to the E80CC - and just as an indicator of how good, I started out with a Mullard 10M ECC82 in there - and an E80CC which I believe to be a US made Philips (not the best of the E80CC's by any stretch) completely outclassed it!
A better choice than the 5814A, I think, is the Tungsol 5963, or even the RCA black plate 5963. Not up to the E80CC, but close.
When you swap the caps to Black Gates, keep the Jensens in there now, as well as the Wimas, and watch out for the sizes - there is not enough real estate on the DAC 1.1 boards for some of the best Black Gates. There's no point in changing the existing carbon film resistors in the stock unit as they are quite good, but getting rid of the rest and going to Tantaliums and Riken carbons is a big step forward.
You are right, I find the DAC has terrific pace, and with the improvements I've done so far, the analog like qualities are enhanced and overall the DAC becomes bigger, quieter and more rounded. Detail is abundant, but so is the warmth and tone, as well as a very rhythmic quality.You should hear Pink Floyd's new live Wall set on this baby!
Robert,Thanks for the GREAT info dude.

S U R E... Make me jealous. :-{)

I didnt comment on the sonics or the sound of any dac in particular , I was commenting on the "signal manipulation is bad issue" (which it isnt)
Some stuff in digital design cant be thrown away , as much as you would like to , without stuff like jitter management , dither etc most cds would still sound like early 80's poorly transcribed stuff
For example take the cd "THE POLICE every breath you take- Classics"It has been remastered using a dithering process and it sounds a lot better than the songs on the "Syncronicity" cd.
Again, listen to the DAC 1.1, or even better, the DAC 3, 4 or 5 - it DOES throw away that stuff, and all of a sudden digital sounds good - real good - and the other high priced 'by the book' stuff doesn't.
The AN Dac 4 Signature ain't cheap. I think it retails for US$18,000.

How much does the Levinson, Wadia, Theta and Meridean go for? Guess what i am trying to say is that there are many expensive DACs. This is why i wanted to review the DAC Kit 1.1 for my e-zine as it was VERY reasonably priced and VERY tweakable :-{) . Anyone can review and give a rave review to a $10,000+ product. Findinf those inexpensive jewels is another issue.
Of course i LOVE my Clearaudio Insider Reference cartrige so i have sinned a thousand (or is that 10,000) sins.
Damed if you do, damed if you don't.Enjoy the music (Alan Parsons "Damned If I DO" on vinyl right now),

"I ain't got a heart of stone
I'm hurtin' more now than I've ever known
If you mean the things you said
I'm gonna wind up outa of my headCan't sleep alone at night
I just can't seem to get it right
Damned if I do
I'm damned if I don't but I love you..."
or else you don't know what you mean. Just because the Audio Note DACs don't oversample doesn't mean they don't benefit from dither added in the recording process, or that they won't sound better with a low-jitter transport (IMO, this is why they included an AES/EBU digital input in a relatively low-priced DAC, to allow for the inferently lower jitter of that connection).
EVERY DAC sounds better with a low jitter transport - the better the data stream, the better the results. I didn't misread Rodney's posts and I know exactly what I mean. I simply said LISTEN to the DAC - I didn't comment on any of the issues you raise.
