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.

Another Davinci2 owner was a previous Bricasti SE DAC owner and said that although close, the Davinci2 was unquestionably superior.

I will I’ll ask him to bring it over the next time he comes so we can hear it in my system.

I believe that the top tier TotalDAC is something special. I intend on getting it in sometime this year, but it’s a huge multi unit system. The TotalDAC system, TrinityDAC and MSB Select 2 may be the only thin to outperform the Davinci2. Of course, there’s CH Precision, Soulution, DCS Systems and such as well, but I think that like the Boulder they offer dynamics and detail but lack musicality (totally my opinion, and some of it assumption and not a result of listening).

Thanks Steve, for the complement. I try to keep things objective in regards to apples to apples comparisons, consistent and honest.
....but the issue with Delta-Sigma is the filtering. The issue with R2R is this non-linearity.

Perhaps I’m "fanning the flames" here just a bit, nevertheless, I’d like to comment on this in particular because I was/am well aware (so I think) of the "filtering" long before I posted in this thred.

My Oppo UDP-205 (delta-sigma) has a user preference setting whereby the filter can be changed. Way back, I did some research as to what this entailed, and found it had all to do with "pre-ringing", "post-ringing" and basically everything at the 20 KHz point. I tried all (7) available filters and none made the sound "better" than the default (mini-phase fast). It only made it as good or worse, to my ears.

So, what "filter" is the issue with delta-sigma?

Per Steve’s last post above, this is exactly why hybrid ESS 9028 designs are way ahead of everything. 

The latest ESS designs are halfway between the R2R style and delta - sigma! The 9028 a 6 bit delta sigma by virtue of hundreds of 1 bit delta sigma on the chip!!!

jwm and charles1dad - I think the problem might be the system.  Each of you heard the same two DAC's, but in different systems.  It is very possible that one preamp or set of cables made one DAC sound better than the other and the opposite in the other system.

There is certainly expectations and listener preference, but I would suspect that it might be more the system effect.

Filter response, such as "apodizing filters" are not what I'm talking about. If you want to really improve Delta-Sigma filtering, you have to either eliminate the digital filter completely, replacing it with analog filters, or set the filter frequency much higher than most chips do automatically.  This effectively removes the effects from the audio range.  This is what I do in my DAC.  The user can select the 192 digital filter when playing back 44.1 files, and this is how most customers use it.
