NOS DAC or CDP?

Recently I had to get rid of two of my CDPs (Jolida JD-100 and NAD C542) for finacial reasons. In doing so, I've had to go back to using my old Onkyo DX-C540 changer. Now it's not a bad sounding player for what it is, which is a Mid-FI changer circa late 90s. But both the NAD and Jolida certainly bested it in all areas of performance, and yes, I'm missing that level of performance. In any case am thinking down the road of either getting another CDP (possibly another NAD or used Jolida) or maybe going the NOS DAC route. I'm thinking of going the NOS DAC route as the Onkyo DOES have a optical output, and I think that it might make a decent transport, and give me changer capabilities. In addition, from what I've been reading the NOS DAC would probably give me the warm, musical presentation that I enjoyed with both the NAD and Jolida players. Also it appears that many of the NOS DACs fall within the "price point" that I would like to keep (less than $500). BTW, I consider myself more a "music lover" than an "audiophile", and going the DAC route would certainly be something new for me. Anyway, appreciate thoughs and suggestions from the community on which road they might go down and why they so. Thanks.

I can respect Muralman's opinions because I also felt that way at one time, but again there are benefits to OS designs IMO as well. Here is some interesting reading I have come across over the years (yes, perhaps embellished with some marketing language but I'm going to assume we're wise enough to read between the lines):

Lessloss Slaving (read through a few pages)

Lessloss Jitter (follow the steps under the diagram)

47 Labs NOS

Digital Diversions

All of this really just supports the fact that there is more than one way to do digital right.

My sound is supremely cohesive, detailed to the minutest signal, and wonderfully analog. OS DACs sound terrible, and I don't care which one. I can demonstrated the difference here, and have, numerous times.

Yes, I can see from your virtual system that you have an amazing setup. Well done!

By the way, change out those milk toast diodes out of your transport and DAC for some super Shotkeys and bring the live band in.

Interesting idea.

I can see you are dead against OS DAC's - no problem - I can understand your perspective as the early ones were indeed quite bad and probably no improvement over older DAC's (but that was before clock speeds/accuracy improved - it is always a moving target with time as to which architecture works best)

Clio09 - in April 2009 issue of Stereophile (also on their website) they review Meridian 808.2 CD player. It is upsampling player with different algorithm digital filter. They claim it is the best player they've heard ever (and better be for $16k). That would suggest some deficiencies in traditional digital filtering.

Cleanedup- You've obviously stumbled into a controversial area. I think I share your view of "listenable" audio. The NOS DAC I have (original MF V DAC) sounded terrible when driven from my Mac Mini until I added a jitter control device (Theta TLC). I have moved to a PS Audio DL3 OS DAC, which sounds pretty good but not "magical". Now your transport will have less jitter than the Mini so the NOS DAC may sound OK. You can always add an anti-jitter device later. On the other hand, there is a tremendous variety of used CD players with that warm sound. My Arcam Alpha 9 is really magical. There are many, many other really nice CD players with plenty of reviews on them on line. I'd go that way if I were you.

"Cleanedup- You've obviously stumbled into a controversial area."

Without a doubt, and both sides make good points in supporting their arguments on which types of DACs are best at doing the digital to analog conversion. As such I'm still in the research mode, and still "on the fence" on whether or not, to add a NOS DAC, and possible jitter control device, or else go with CDP that gives me the "sonic presentation" that I'm looking for. It appears either way, I'll be spending about the same amount of money, and probably be achieving somewhat a similiar result. Btw, thanks for mentioning your Arcam Alpha 9, might have to look into what Arcam has to offer.
