Better CD Sound: The Search

Went Big into Vinyl last 2 years, then re-discovered my many CD’s, mixing it up plenty now.

I continue to try and find a CD Player with better sound than my existing cheapo Sony Changer that surprisingly keeps on keeping on.

I am hoping recent upgrades to the system will more readily reveal differences:

99.9999 copper speaker wires and interconnects, locking rca connectors, mx110z tube tuner/preamp overhaul by Audio Classics; cayin a88t bias by VAS; 16 ohm L-Pads replacing 8 ohm pots; and finally a I bought a sound meter to balance/refine the speaker’s L-Pads (it ain’t easy) for the best sound ever.
.....................................

CD Quest So Far:

I want dual processors, go used to keep cost down, even consider older vintage.

1. my Onkyo Grand Integra (DX-7500 I think), fixed the damn drawer opening problem several times.

2. This cheapo Sony Changer given to me, eh, use if for parties, why not.
surprisingly sounded as good as the Onkyo to me and friends, gave the annoying Onkyo away.

3. tried used Oppo 83 Video Player for it’s audio

Laser was weak, ’no disc’, found it is a common problem with heavily used lasers. Back it went

4. lightly used Oppo 105. Everything worked, but didn’t sound better than the Sony. Oppo is big, single, expensive, not sellers fault, so I sold it myself rather than return it, lost $205. on that attempt.

5. ’new original stock’ KLH (made by?). played a few discs, then the discs started mis-tracking on discs I know are ok.

found small black bits clinging to the surface in the area of the problems (cds play from the inside out, just guess how far out). Turned out, the belt(s) were dried out, thus when put into motion after years of storage (where?), they shed bits of rubber. Back it went, full refund including return shipping. never compared it to the Sony’s sound

6. Resolved: if vintage, make sure belts are available, get a low price, open it up when it arrives, watch it move ... use, replace belts, return as last choice.

7. Just Bought Two, in transit, One Single; One 6 Disc Changer. (both with oem remotes and power cords, most for sale are missing).

a. Denon DVD-2910 Single Player (big dent on the top. $52. del’d, eBay) (crutchfield keeps old info on their site)

b. Onkyo Integra CDC-3.4 six disc changer (open box/demo) ($51. delivered) (bserplus.com)

@in_shore,
Okay, the convenience factor, I understand.  It was your comments (And those of other there)  on another thread that got my attention regarding the Pro-Ject RS2 transport.   When you wrote it sounds better than your 432 EVO Reference music server playing files or streaming. That is quite a compliment. 

I'm looking forward to hearing the highly praised RS2 transport in my audio system very soon. I believe many people underestimate the importance and contribution a quality CD transport (With over emphasis on the DAC).

@in_shore, 
Did you find the difference between the wall wart and the optional linear power supply subtle (Yet noticeable) or significant?

If your are willing to use your existing player as a transport, I would urge you to consider external DAC like the Denafrips Ares2 (sub $800) or better models.  I love mine. If you are willing to replace your Sony player,  the Marantz SACD30n (~ $3K in USA) that sounds superb and is also an excellent network streamer and a very good DAC for other devices to connect to it !  It also plays SACD's flawlessly.  I am sure there are even better players / DACs out there but for the money, I believe these units I listed are hard to beat.  GOOD LUCK !

@clearthinker  " I have always wondered why someone doesn't build a player that reads the disc without using any clock, buffers the bits for half a second or so and spoonfeeds them to the DAC at nice even intervals using a separate clock?"

PS Audio has been doing something like that for quite some time, with their original CD transport, the current SACD/CD transport and the one it replaced.  It reads the bits off the disk, places them in a memory buffer then delivers them in a more "timing sensitive" mode to the DAC.  From what I've read, conventional CD players do some re-reads and corrections as part of the process of getting the bits off the physical disk, which apparently effects the timing of the bits arriving at the DAC.

Yes, "bits are bits", but what people who are digital audio experts say, the timing of those bits is crucial to the sound quality.

On a related note, yesterday I "pulled the trigger" and ordered the new PS Audio PST PerfectWave SACD Transport, taking advantage of their sale price, which is good through the end of October.  I currently own their previous model, the DMP and their DirectStream DAC.  From what I read, the PST provides a noticeable improvement over the DMP, especially for conventional CDs.

If you want to do something budget-friendly, I use my Sony Blu-ray player for a CD player.  The sound quality is a significant improvement over the Yamaha CD changer I had been using.  The issue is finding one that has RCA outputs, as most of the new ones only have an HDMI output.  I was lucky enough to find mine at Goodwill for $10, but I'm sure you could find a gently used one for just a little more than that.  And if it isn't to you're liking, you're not out much.
