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.

ctsooner - I will call and ask the specific of the meeting at Audio Connection. I would love to go if I can get free...

Steve - Thanks for the suggestions. I definitely will.
I have 2 dedicated 20 amp circuits running to the rack, one for digital, 1 for analog. Each runs to it's own single outlet.

I'm going to pass on the isolated ground rod thing. As I said, I found some simple to implement (and inexpensive) solutions. I'll stick to my grounding bar in my sub-panel...
Ctsooner, based on your latest post it sounds probable that the electrician simply installed what are commonly referred to as dedicated lines for each of the outlets, which is fine.

I had been interpreting your earlier statement, and Agear's as well, to amount to what is depicted in the figure at the top of page 8 of the reference I provided. That is done by some audiophiles, but would entail all of the risks I described.

Matt, that all sounds fine also. And +1 to Steve's suggestions.

Regarding your questions, my instinct would be to connect the monitor to the same outlet as the computer, and to NOT connect it to the outlet powering the turntable motor. I'm envisioning the possibility that if they were on the same outlet some amount of RFI generated by the monitor might find its way to the motor, and radiate from there to the phono signal wiring.

My instinct/guess is the same as yours, though, regarding there probably being no need to have the trickle charger and the phono stage on the same circuit.
Hummmmmm......
Clever double entendre :-)

congrats mattnship, I did all my wireing to my system, no need for a electrician if you have sence!I have the same set-up a you do, it works!, however, remeber, though a dedicated ground for each circuit does sound better, doing so will not flip each breaker on this scheme when problems occur, thats why it is not code!

I'd recommend for your electrical is to have totally separate and grounded (to earth) circuits for EACH outlet. I did that and it makes a huge difference.

I too have dedicated lines with with isolated earth (ionic) grounds.
Matt, I would advise against this, if I am correctly interpreting that what is being recommended is running outlet grounds to an earth connection other than the one that grounds the service panel. If that is not a correct interpretation of what is being suggested, I'm sure the others will clarify further.

Any two bit electrician could provide that counsel. Al, how do you optimize grounding, or are you one of these flat earther engineers from the 1950s who believes coat hangers are comparable to any hi end cord and any well designed power supply is enough to negate the need for power conditioning, etc? (Judging by your many posts, it seems you are not). I have conversed with multiple dudes like that on other forums, and it makes for an entertaining thread.

My ionic grounding scheme was provided by Lyncole, an engineering company out of California who typically does defense, military, and lab installations.

I think the grounding game is a very interesting subject and worthy of another thread as Al suggested. I have quite a few audio buddies who have toyed with grounding boxes (Tripoint and Entreq) to good effect. The stock engineering response is that the only reason those boxes work is poor equipment grounding schemes.
The best grounding sceme is to isolate every components grounds from each other in the signal cabling, but use common earth ground for all, so there are no ground loops. I do this using combination of good analog transformers and digital isolators.
