I have always heard a slightly dry, mechanical presentation from digital. Most of the digital that I have heard has produced a high frequency distortion to which I am quite sensitive. I often become fatigued and usually lose interest pretty quickly. In the rare instance when this has not been the case, I think it is because the DAC is voiced to sound warm or “analog like”, or the system has tubes or some other distortions that mask what I hear as a typically harsh digital sonic signature. I heard none of this with the Vivaldi or more recently with the Rossini DAC. In fact, I think I more clearly heard the capability of the Rossini with the Magico Q1/Spectral than I did of the Vivaldi with the Magico S7, because I actually think the Q1 is more transparent than the S7, but that is a discussion for another time.
Resolution is one area that I had always heard good analog to be superior to digital. The Rossini had an incredible amount of resolution, rivaling really good analog, and yet it sounded very smooth and relaxed. String tones, vocals, piano, drums, horns, I heard more detail than I had ever heard from digital before, but with absolutely no harshness, glare, etch, or digital artifacts. There was no fatigue. The instruments were separate in space, with lots of air. Hall sounds were very evident and clearly defined the recording venue. What also struck me was just how natural the sound was. The Rossini presented the notes completely, not emphasizing the transients, or the harmonics, but the whole note, from beginning to end, was heard in a continuous and balanced way. The note’s attack was dynamic and impactful, the fundamental were accurate with beautiful harmonic and a natural decay.
The Rossini was superb in these two critical areas. The Berkeley Reference DAC did not fair as well. I am familiar with both Al’s and Ack’s Berkeley Alpha DACs, so I was interested in hearing this new version, especially since I have read so many nice reviews. Well, it did have a great deal of resolution, though not as much as the Rossini, and certainly not as much as the good analog that I have heard. But, what was really strange was how it reproduced the notes. It did not sound natural, but rather artificial. As I mentioned earlier, the system was so transparent, that I was able to hear what I think is a fundamental flaw with this DAC. I do not hear this issue in Al’s or Ack’s system and I have not identified this sonic anomaly in any digital player before. The notes were neither complete nor continuous. I heard an emphasis on the leading edge, or transient of the note, and then a strange discontinuity immediately afterward around the fundamental, then pretty good harmonics, though not fully developed, and then a truncated decay. This gave the initial impression of good detail, but it was an exaggeration, a distortion, and it could not be ignored once heard. It was fairly subtle, but I heard it in all the music we played. Again, this was a testament to just how transparent the Spectral/Q1 combination is.
In addition to what Al brought to hear, I brought one CD from my small collection: “Best of Chesky Jazz and more Audiophile tests, Volume 2.” We repeatedly played Kenny Rankin, “Always”, and test tracks #43 “Dynamic Drum Test, and #44 “Bass Resonance Test”. I have used these superb recordings for digital system evaluation for years. Rankin’s voice and finger snaps sounded very natural. Quick fingers with fleshy palm and natural echo in the room. His voice had all the nuance of what we hear live. Very revealing of the quality of the reproduction. The drum test was also informative. The cymbals were metallic, distinct and clear with the Rossini, but they were a bit whitish and splashy with the Berkeley. The drum skins were detailed and taught and the bass was impactful with the Rossini, while the Berkeley just sounded a bit artificial. The timbre was not as accurate. With the bass test, the Rossini had all the nuance and beautiful balance of string, bow and wooden body while the Berkeley emphasized the plucking but did not quite reproduce all of the different tonal colors of the strings resonating with the wood. And there was less air and hall information in the rather live acoustic.
I was mesmerized by the Rossini, but I thought the Berkeley was just good digital that I had heard before. The Rossini sounded much more real and approached the good analog that I know so well.
I want to write a bit about my recent thinking of what component is responsible for what aspect of a sonic impression. I think that the source components are basically responsible for extracting the recorded information. The electronics and speakers present that information. The less distortion the better. The set up or relationship between the listener, the speakers, and the room recreate, or destroy, the sense of presence, dimensionality, scale and palpability of the performance.
At Goodwin’s, Al and I heard what great digital is capable of. The information retrieval was of the highest order. And, as was said before, this was just redbook CD. The electronics, cables and speakers presented that superb resolution in a very transparent and believable way.
Thank you Al for asking me to join you for this incredible demonstration. Goodwin’s High End was extremely accommodating and generous with their time. It is a great place to do such direct comparisons. I learned a lot and have a completely newfound respect for what is possible with digital playback. I was very pleasantly surprised and now know what digital is capable of sounding like. It was a great afternoon and it has changed the way I think about audio in general, and digital in particular.
There are the thoughts of an analog only guy about the best digital that I have ever heard. It has really changed my thinking about the whole analog/digital divide.
Gentlemen, I'm confused about one thing: is the Rossini better than the Vivaldi? Has the vivaldi been discontinued?
Robert "worthless to the audio fan" Harley recently proclaimed that the Berkeley Reference DAC was "the best dac", just 2 months after he proclaimed that the Vivaldi was "the best dac". Of course, he never compared the 2. Actions like this just make him seem like a marketing agent for Berkeley than a friend of audiophiles trying to navigate the morass of digital:

Thank you again, Al. This hobby needs more true fans such as yourself writing about their experiences.
Now that you found something you find truly special, I think you should bite the bullet and purchase it.Why procrastinate?

Money doesn't grow on trees. I tell you, if I had the money, I'd buy tomorrow the whole dCS Rossini/Spectral/Magico Q1 set-up that we heard. Not that this might not happen eventuallyGoodwin's really know how to suck you in with an outstanding demo, but that's what a great dealer is there for.
I sure want the dCS Rossini eventually. Let's see if Madfloyd beats me to it![]()
As a general rule of thumb, people advise that digital equipment NOT share a ground connection with other equipment. I am of the same opinion, and it's more than an opinion - I have experimented heavily with lifting the ground on my Alpha DAC, and at the end of the day there are a couple of data points:
1) My phono picks up a little bit of hum (with the preamp volume maxed out) from the Alpha and its ground connection, and it goes away when I lift the Alpha DAC's ground
2) The phono sounds a little better with the DAC's ground lifted
3) The DAC itself sounds sizably better with its ground lifted, and more than that, I star-ground to the preamp by lifting everybody else's ground (sort of what the Entreq folks are indirectly doing, w/o the cat litter and magic dust which is not necessary). Unfortunately, I have not demonstrated to you guys the benefits of this preamp-star grounding.
To get to the point: always audition a DAC or CD Player with and without its ground, or at least inquire about it. Based on my experience, the Berkeley Reference stands a chance to sound better than what you guys described. Having said that, my guess is the Rossini is still a better DAC, and I'd be curious how it sounds with its ground lifted, if it wasn't.
To be honest, I don't know the filter setting. I do think that upsampling is default.
Also, Why didn't you ask to hear both DACs connected directly to the Spectral amp?
This whole concept that Spectral amps must be only used with Spectral preamp is BS.
Marty uses a tube preamp with his Spectral amp and Reference Recordings uses a Berkeley DAC connected directly to a Spectral amp.
The instruments were separate in space, with lots of air. Hall sounds were very evident and clearly defined the recording venue. What also struck me was just how natural the sound was. The Rossini presented the notes completely, not emphasizing the transients, or the harmonics, but the whole note, from beginning to end, was heard in a continuous and balanced way. The note’s attack was dynamic and impactful, the fundamental were accurate with beautiful harmonic and a natural decay.
a note to Al M. after our conversation a while back i went room treatment crazy, plus speaker placement mad... great results so thanks for prodding me.
Thank you very much for this info, Ack. Just a question from a technically inexperienced guy like me: what do you mean by "lifting the ground"?
Tell that to Spectral.
I had called the Spectral factory two and a half years ago after I first heard the amps in my system and pointed them to this fact about Reference Recordings. They said that their power amp was custom modified to allow for that; Spectral amps normally need rather high power in their input. When I asked them why in this digital age they did not give any customer that obvious option I could not get a coherent explanation. Very nice guy though with whom I spoke.
If you ask me, it makes no sense why they would not provide that option. It would save an extra pair of expensive interconnects too. I think the factory could get much more sales with that configuration (and if the price of the power amp with the more sensitive input would have to be somewhat higher, so be it, no big deal for most, I would think). It's old school thinking I guess, rather odd from a company that is so much on the cutting edge of solid state sound quality.
If they had provided that option, I might have bought a Spectral amp already. But boy, do those amps sound great...
On the other hand, it remains to be seen if the dCS Rossini as a pre-amp is as good as a Spectral pre-amp. Perhaps the drive to perfection compels Spectral to stick to their philosophy.
The DMA-160S Studio Universal has been designed as a stand-alone reference amplifier for use in various applications in studio monitoring and audiophile systems where a Spectral preamplifier is not available. The stand-alone capability of the DMA-160S is achieved with an exclusive “active buffer” input topology which can maintain optimum input matching with high-level source components without compromising internal bandwidth.
At the end of the day, they did not sound as good as their brethren, and I verified that for myself - probably that "active buffer" was not that good. So they then abandoned that approach... So when you say "I could not get a coherent explanation", I take it with a bit of salt, and I suspect they might have told you it was all about optimizing performance.
Finally, one thing I would agree on is that the amp/preamp you heard are pushing the envelope in transparency - straight-wire-with-gain if you will - to levels I have not heard anywhere else yet.
Any chance you could ask Paul what settings they use?
Dan, let's not put members who share their experiences this way on the witness stand with this type of tone. Otherwise it may discourage them from sharing such in the future. Ask questions but don't get personal this way.Maybe if you had done a little research before going to your listening session, you could have asked to hear the Rossini's different upsampling and filters.
