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.

Steve-

I believe your Diamond SX is something special and will quickly be noticed in the audio community.

Since these units are now in very limited supply, would you post your thoughts on the sonic qualities of for each build option? For those who have never been to Steve's auditioning system, his perception is spot on.

What I am curious to learn is the benefits and disadvantages of:

XMOS USB (which I find better than M2Tech) compared to your external ethernet to I2S converter compared to internal ethernet to I2S direct. For those unfamiliar with the overdrive, the internal USB input card can be replaced by Ethernet to I2S. No dac will have both USB and Ethernet due to the compact chassis design.

Currently on loan to me is a dac that has all these inputs and Ethernet direct is by far the best. But again, implementation is important. I have yet to see a dac better implemented and designed than Steve. There are so few dacs with direct Ethernet, that I am uncertain if the concept or implementation makes it better. Steve, what are your thoughts on Ethernet direct input? I have from two sources that in Asia that the majority of audiophiles do not use a server and dac design focus is more on Ethernet because 80, 90, 95% of the consumers solely use this input.

Second comparison:

What qualities do each brand of caps bring to the table in your SX design? Will you have a few units in possession and be able to directly compare simultaneously?

This insight will pay dividends for us who have specific needs tailored to our system. What I have learned is benefits do not translate to each system uniformly.

Steve, I commend you on your years of service both as an engineer continuously improving on already amazing products and creating a successful business. Rarely I find a one man show able to do both so well. You are genuine in your advice to your consumers and foremost genuine in your advice to your competitors. What most manufacturer would consider propriatary, you openly share for the good of the community. In this regard, I consider you a Professor. This is the highest respect I give anyone in my field.
You go Charles! Mandate the cars we must drive? Come on, perhaps we better get back to audio folks. The wheels have come of the track here.

I let my car warm up here in Minnesota when it is below zero so I don't drive shivering and become a dangerous driver. Ok if I burn a little fuel.
I am proud to be an American and love my neighbors!
Charles and Bill,
I fully agree. I do my part already, low powered amplifiers.
"XMOS USB (which I find better than M2Tech) compared to your external ethernet to I2S converter compared to internal ethernet to I2S direct."

It will be about 3 months before I can do this comparison. I will be out of town starting March 20 for 4-5 weeks.

"What qualities do each brand of caps bring to the table in your SX design? Will you have a few units in possession and be able to directly compare simultaneously?"

I have two ODSX, one with Jupiter and one with Duelund caps that I am running currently. Either the Jupiters have really overblown bass and somewhat recessed highs, or they are not fully broken in yet. They sound great on older 70's tracks that have thin bass, but newer tracks are just over the top.

Ketcham - You are too kind with your kudos, but on the other hand I'm glad somebody finally gets what I'm about.

I hear they both take many hours to break in. But I have not heard either myself. What do you like about the duelund? If I am able to source some silver duelund caps I may have you run those. What spec caps are required? I remember there are 4 total. I believe the Jupiter caps are silver, and if so ups wonder if they too will have a similar affect.

Does duelund offer discount to industry Manufacturers?
