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.

Yes I’m familiar with MSB and have heard a few of their DACs. No doubt that they are fully committed to discrete resistor ladder R2R . I understand the supposed merits of this approach. I used to own a Metrum Octave DAC a few years ago and brought it primarily due to its R2R approach and universal rave reviews. It was in fact a good sounding DAC but preferred the Yamamoto DAC (DS) in my system. I heard the Holo Audio Spring level 3 DAC (discrete ladder design) in my system. Very good but again I found the Yamamoto YDA better sounding. The Metrum and Holo Audio are representative of "bit perfect" given their architecture. TotalDac (bit perfect) outperformed by the delta sigma Bricasti SE in a friend’s system I listened to extensively. .

George it could be as simple as we heard differently. I’ve listened to a number of R2R DACs and they ranged from good to exceptionally good but did not exceed the sound quality of comparable delta sigma DACs. We both have our respective listening experiences and subsequent outcomes. At the end of the day we judge and formulate opinions based on what we have heard.

Here is a thesis paper explaining why R-2R DACs have lots of harmonic distortion.

Looks like the distortion is consistent across all harmonics.

These students were sponsored by NAIM to investigate ways to reduce this non-linearity harmonic distortion that is inherent to R-2R designs.

The 2nd harmonic will give this kind of DAC a richer sound. The higher odd harmonics will tend give an R-2R a slightly harsh edgy sound in the treble. My guess is that R-2R DAC manufacturers will use filtering to roll off the highs in order to reduce the odd harmonic harshness in the upper treble. Subjectively this might be preferable to a higher performance DS DAC.

Hi shadorne. I have no disagreement in what you are stating in your previous post. I would just like to submit as food-for-thought that Jimi Hendrix used fuzz distortion. Not quite the same as the distortion you are speaking of, nevertheless, worth mentioning, IMO.

EDIT:

....that would be *intentionally* used....
George frequently to support his point says R2R is "bit perfect" whereas delta sigma is merely a "facsimile". As a listener I don’t hear R2R superiority. As a builder/designer is this claim true and if so is it an audible or meaningful distinction in your experience?

I have compared D/S to R2R with my own DAC designs. The D/S is better, however my R2R was using older chip-based technology. Some of the new clever design tricks with R2R overcome some of the limitations of older chip-based technology. The accuracy of each level is still an issue however, so this causes its own distortion.

When you compare these two technologies, you are comparing two different deficiencies. The question is: given both designs are excellent, which one sounds more live to you?

I have personally had great results with D/S, but if I designed an R2R from scratch, it might be equally good.

Hi Steve. Not meaning or wanting to play on words here, but for clarification purposes, by "live" do you mean "authentic"? Thanks.
