Ceasar,
I have only heard DCS Elgar Plus/Verona and i just heard the Scarlatti Transport, Clock, DAC today in a system i know very well (many of the parts incl the speakers i used to own). Here is my personal take compared with my own Zanden. Redbook only since Zanden is 16/44.1, though i did also hear SACDs on DCS.
1. The DCS is a stunning achievement. It is a far more technically accomplished piece of equipment than its predecessor, as well as the ARC 7, 8, Krell 505 (all costing far, far less) which i heard in the same system. It leaves a wide gap in technical performance. Dead silent background, extraordinary retrieval of decay and detail, and also carries a natural tonality with its music that is probably the most noticeable improvement over the Elgar Plus.
2. I found a near-complete lack of "shimmer" which i often hear on digital sources. the treble is totally solid which is a shock the first time you hear it
3. Further, its Filters 1-4 help shape things a bit. In fact, i would say that given how technically accomplished it is, and how variable its settings are...you have the very strong ability to set it into many, many systems and get remarkable sound.
3. Now...here is the rub. We played with the system a good deal all afternoon to optimize. In the end, i would knowingly sacrifice the pitch black background, the extraordinary detail...and the lack of shimmer for my Zanden for one reason alone...liquidity/musicality. The DCS (to my ears) felt a touch, a spec, a nano-milli-something dry for my personal taste, and as a result i found myself marveling at its delivery of VERY NATURAL SOUND...but i stopped listening to the music. Honestly, i cannot say why...i just did. With the Zanden with its relative "flaws" or imperfections, i found that i just listened to music...i listen to Starker vs Rostropovich, Gardiner vs Klemperer...NOT cymbal decay here vs cymbal decay there. i found myself "flipping tracks" much more with the DCS...to hear that first bit of decay, or that bass hit there...as soon as i went to Zanden...i stopped doing that, and kept hesitating to change tracks because it killed me to stop the music.
in sum, i respect the DCS deeply...and those who own them are truly fortunate to have such an immense player. it is in a class unto itself relative to the CD8, Wadia reference, Esoteric X-01, (older) Emm Labs CDSA, even in technical terms to the Zanden. But i would not trade my Zanden for it.
Yes, I have heard the Scarlatti a few times as well, and I pretty much agree with your observations. The main issue with the Scarlatti is that it is a system. Once you start removing parts of the stack, it becomes just plain ordinary, and approaches the sound of the single box Puccini unit.
I have not had a chance to compare it to other high end players, however, and your observations about Zanden are very enlightening. And that is why I'm so down on audio reviews, who don't bother with comps...
With that said, I know I could live with the Scarlatti ever after. But only if my portfolio were to double many, many times over.
