Absolute top tier DAC for standard res Redbook CD


Hi All.

Putting together a reference level system.
My Source is predominantly standard 16/44 played from a MacMini using iTunes and Amarra. Some of my music is purchased from iTunes and the rest is ripped from standard CD's.
For my tastes in music, my high def catalogues are still limited; so Redbook 16/44 will be my primary source for quite some time.

I'm not spending DCS or MSB money. But $15-20k retail is not out of the question.

Upsampling vs non-upsampling?
USB input vs SPDIF?

All opinions welcome.

And I know I need to hear them, but getting these ultra $$$ DAC's into your house for an audition ain't easy.

Looking for musical, emotional, engaging, accurate , with great dimension. Not looking for analytical and sterile.

His search will NEVER end! Seems Matt is more interested in equipment than muzic.
This is precisely the reason I don't chase DACs. Until the technology matures, I will only upgrade when necessary.

Steve, I'm surprised at your question.

What I'm talking about is the fact that depending on the quality of the design digital noise can couple between different parts of the circuitry in a component, via grounds, stray capacitances, etc. Potentially/theoretically resulting in increased jitter at the point of D/A conversion, and/or effects on analog circuitry.

Where did you get your EE degree?

BSEE Columbia University
MSEE Rensselaer Polytechnic Institute

+ 33 years experience designing and managing design of analog, digital, A/D, and D/A converter circuits for defense electronics.

In any event, the bottom line on both of our posts is the same: Implementation is what matters.

Almarg, Very Classy reply!
Audioengr, have you considered caching on the client/DAC side after the interface that receives the data? Now the client should be agnostic how the data was sent?
knghifi - Isn't the storage of the data in a buffer after de-packetization in the device sufficient?
Yes. Not familiar with your design.

Just curious, how big is the buffer or how much do you cache in time domain?

Well, if the sound of the PS Audio Bridge is representative of what Ethernet has to offer, count me out. I thought the Bridge, which streamed audio via an Ethernet connection, sounded awful.
I had a PS PWDMKII w/bridge and it sounds wonderful in my system. It also sounds wonderful in 2 other systems I heard so I think the problem is somewhere else in your system. Bridge was best digital input for PWDMKII in terms of SQ.

My complain with the bridge is instability. I have to reboot it daily. Every few hours, it just stops playing. I hold my breath with every firmware release whether if it will work or inferior SQ. I could go on and on ... I'm done with PS Audio until they have their act together.
Oh, and I guess I do need to decide which speakers are my keepers. I'll keep the suspense running for now.
Here's a suggestion, keep the Dynaudio and when you and neighbor both need a change, swap speakers.
ELAC introduced a floor standing speaker for well under a grand that sets a new level for everyone to keep up with. The tonal color and layering were dead on and they way outperform their price level.
These are Andrew Jones ELAC debut. He wants to put ELAC on the map before creating SOTA to compete with TAD. I'll probably order a set for HT.
The real solution is using wired Ethernet instead of USB. This is a solution that makes the computer and its power unimportant. Cabling is unimportant. Even the playback software should in theory be unimportant, but I feel that it will be. This is why I am working on this solution now.

All of my USB interfaces will be upgradable to wired Ethernet LAN interfaces.
This is reason I use wired ethernet via DLNA for years.

Steve, I am finding that the Ethernet cables are important, the supplies for the router and NAS are important, as well as the hard drive in my setup. FE, SSD are more clear sounding than standard HD's in the NAS.
If the server process caches TRACKS before streaming to the DAC, then only ethernet cables between computer to dac is important.

I find replacing generic with AQ ethernet cable made a nice improvement.
I've been using ethernet via DLNA for years.  Never bothered with USB and PC in my sound system ...  

Have you guys tried running MinimServer in a NAS drive so PC is not necessary to play music?
