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.

Matt - I recently built an ODSX for a customer that did not care about 176 or 192 file playback, so I installed my new XMOS USB interface in it for him. This is the first one like this. This combo is simply incredible. Hands-down the best SQ I have ever heard, from analog or digital sources. Even really old tracks, like Peter Frampton live sound amazing. He also ordered my Power Block USB cable supply to go with it, which makes a big difference.

I am still working hard on my new Ethernet interface, which supports all formats, PCM and DSD. I should have one running in the next week I hope. This I think will be the default interface for the ODSX.

Steve, will that USB module ever be available for public consumption or will Ethernet be the new interface king?
Matt, you might want to check out the Clarus Crimson HC power cord for your amp.  I have one on my Mark Levinson 23.5 and it made a big improvement.
Thanks for the response Mattnshilp.  I trusted you (and others) would find the questions reasonable.

As a CPA, I can fully appreciate how a cash crunch and timing can often make decision making seem illogical.  I was looking at it strictly from a SQ and long-term $$$ issue.

Perhaps you can use the Cable Company for your power cord upgrade to try and find the right match without experiencing the same buy/sell issue you did with the Plasmatron.

I would just caution that the Plasmatron is basically just a voltage sag prevention device (not even for amplifiers).  It's not a power conditioner as the mfg. specifically states.  Thus, if you experienced a benefit, it means that your house has voltage sag issues and/or the power supplies in your equipment deteriorate in performance without the help of this device.  I'm not sure you can "offset" that benefit with any passive power cord on the market, but best of luck and please share if you do.

The only thing I'm still confused about is your comment that you "don't buy and sell things".  Were you being facetious because every sentence after that referred to currently buying buildings and selling speakers/watches/plasmatron? 

Either way...good luck.
Agear - The ODSX will have option of having USB or Ethernet input.  The current USB is M2Tech but I suggest waiting until the XMOS is figured out.  Steve is creating a new device where Ethernet converts to I2S.  This is different than his Offramp 6 that will soon be released as well that handles DSD throughput.  The Ethernet to I2S can either be an external unit or an internal unit for the ODSX in place of the USB.  Given my personal experience, I believe the internal Ethernet to I2S will beat Ethernet to high grade server to ODSX by USB.

What is said here about the Plasmatron makes sense.  My voltage varies from 116 to 126, sometimes more.  It is necessary in my system when not running tube dacs.  They seem to tolerate voltage changes better for some reason.  I live in the same region as Steve Nugent and reason he has the same issues as I do.  This is likely why we both find it favorable.  So much so I gifted a 220V version to a friend in Korea.

I also would not be so critical about Matt desire to sell his Plasmatron.  Great, I highly suggest someone take him up on his offer.  They do not come up the resale market.  At least I have never seen one.  Like Matt, as my system evolved over the years, I have many times purchased something and was not satisfied then sold it at a loss.  In total I estimate 50% of cost of my system!  This is why I appreciate everyone's endeavors here.  It helps save money.  Ironically, Matt approached me before the beginning of this thread to purchase my EMM dac2x but I talked him out of it.  I was never satisfied with its sonic signature.  Instead I told him about the Overdrive.  18 months later he acquires an EMM and loves it!  My unit was a very early build and there were hardware improvements this last year.  Maybe it is the unit or it is our perception.  This highlights the importance of auditioning gear regardless of what people say.  EMM audition was not an option back then.  ...audition in your system is essential.  

(Of interests: I sold my EMM DAC2x for $7800 and was difficult because dealer(s) were selling newly built, sealed, from factory units for same or less!).   Summer is a low sale season and dealers often are looking for a quick sale.  EMM is a respectable company and grew up on their Museatex line.  The EMM great dac but not to my taste.  I found the ODSE to be much better and many others for the fraction of the price.

My gear sold in mint condition cheap, the Plasmatron will be a deal for the next guy.

I hope to hear Matt's system in person someday.  Glad his endeavors have paid dividends.


My Emm DA2 is delayed due to manufacturing delays. I'm dying to compare the Emm top dog to an ODSX!

Right now im trying out some power cables to see what best suits my amps. I want to get my power cables settled and my conditioning under wraps as I feel that requires my primary attention right now. I still like the Shunyata gear very much and am inclined to stick with it at the price point I'm at. Once I sell the Plasmatron and my Vienna speakers I can pull those triggers and then finish trying out a few more servers before I make a final decision. By then, hopefully my Emm DAC will be in and I can give you all impressions....

thanks Ketcham and CT and all of you for the supportive words. This thread is so much fun and has taken on a life of its own.
