New DAC Not a Dramatic Improvement?


Ok, So after much thought and asking questions here on audiogon as to whether I should get a new cdp or DAC, I decided on a DAC because I plan on implementing a music server with a Mac Mini. I got it last week and hooked it up so that I could do A/B comparisons with my cdp as is, and through the DAC. My cdp is a 1-2 year old Onkyo dv-sp405 dvd/cd player. At first I was impressed. The bass and vocals were more defined, and there seemed to be more space. Not a lot more space, but just a little bit more openess. The vocals were also moved forward in the soundstage and had more thickness. The thing is, none of these things were very dramatic. THe more time I have sat and listened and done comparisons on many cd's I find the results vary. On some cd's there is significant improvement, and on others, hardly noticeable. In a blind test, do I think I could reliably say whether I was listening to the cdp directly or through the DAC? Let's just say I wouldnt bet my life on it. I probably wouldnt even bet 20$ on it, unless I could hear the two back to back, and on some recordings, not even then.

Now I know about diminishing returns, but I would think the difference between a 150$ dvd/cdp and a 2K$ DAC would be pretty obvious. On top of that, My DAC is hooked up with Transparent Cables (MW Super) and my cdp with 50$ Monster Cables.

Continuing.. I expect some people with say that a good dac needs a good transport. Some will probably say that the dac is being held back by the onkyo as a transport. I have also compared the cdp through the DAC against apple lossless files played from my computer through USB. They are identical.

What could be the weak link? I do not want to say what DAC I am using but lets just say it is a very recent one and around 2K. It is from a very respected company and very well reviewed. My other gear is a McIntosh MA6450 integrated, gallo ref 3.1 speakers, transparent cables. Could it be that my amp is not very revealing? I am thinking about selling the DAC and getting a cheaper one (DAC MAGIC, PS AUDIO DL3) since I will need one for my Mac Mini anyway. Honestly, I just dont think I can justify having 2K in my current DAC for the minimal difference.

Thanks for any insight you can provide.

Jylee may be right, or it could be that other things are also holding back your new dac's potential. Regarding your comparisons, I don't mean to instantly digress to a different subject, but I think Apple lossless is an inferior sounding codec. This has been discussed at length in other threads with diverse opinions voiced. Who knows if our different perceptions are the result of our imagination or different equipment? In any event, I'd suggest comparing WAV files to the cd player just to eliminate a variable. I've upgraded cd players several times and my Assemblage DAC2.7 Platinum has sounded demonstrably better with each upgrade. So, don't discount the transport's contribution. You don't mention anything about your power conditioning, are you using stock power cords and wall power? Attention to this factor can also contribute to a cleaner sonic window that allows for differences to be apparent. There may not be a "weak link" per se. It could be your entire system is not synergistically combined. I'm not saying it is. Just simply stating that sometimes it takes replacing more than one link in the chain really optimize sound reproduction for your room and tastes. If you are basically happy with the sound you are getting, your instincts to get something less expensive and spend resources elsewhere are probably well founded.
Farjamed, it's healthy to sustain skepticism. Good for both mental and fiscal health. I was in the same camp as you, very skeptical of the effects of power conditiong/cables. Now, I couldn't imagine using stock power cords. However, every situation, system, and set of ears is different. There is no universally applicable solution. When I had equipment with less robust and well engineered power supplies, I found power conditioning very worthwhile. After upgrading cd player and preamps, I found power cords upgrades to be much more worthwhile than the power conditioner and ended up preferring things without the conditioner. In the end though, it is true that no tweak, cable, or conditioner is going to dramatically change the character of a component. They can add small, but audible, increments of improvement though. To one listener, that is worthwhile money spent. To another, a colossal waste of money.
