M2Tech hiFace192 + Theta Gen Va synergy?

Mryan, Thanks for your response. Did you compare the HiFace directly to the Legato through the Theta Gen Va?
I read the info on the Legato and they are not clear on their "very well designed" clock. The hiFace uses a crystal, very precise and cheap. If the Legato sounds better then the power supply might be very important. In which case, the power supply mods for the hiFace and also the new model might be interesting. I am using a normal 75 ohm spec bnc cable and have changed the input jack on the Theta to bnc many years ago. I personally think the bnc spec cables are key , and thay those using rca jacks for digital trahsmissions are wasting a lot of money. MUSE only uses bnc jacks for their products.

I think the Legato and the HiFace are in different manufacturing leagues; the Legato is in a 9x6x2 aluminum case with its own internal power supply. Given the reports of the improvements in the HiFace using batteries, I suspect the power is important. However, different USB cables were important to this degree: the best-sounding ones with the Legato omit the power lines altogether. Enough said about power.

My Gen Va and the little HiFace (which I bought while I waited my turn in the ART line) never got happy together; there was too much glare/haze (with the zingy strings and sibilance).

The Legato (which only does 44.1) transforms the Gen Va, which isn't a bad DAC to start with. The glare and haze are greatly, greatly reduced; the sound comes from a blacker background, and the highs are sweet. The Legato beats my Jade whether the Jade uses optical (Theta), BNC, or AES. I don't think you have heard what a Gen Va can do until you hear the Legato.

My Gen Va is a late model with 96K capability. At $2K or so for the pair, (Legato,Theta), you've got some classic high-end sound. Of course, I paid $6500 for the Gen Va back in the day, which is why I am motivated to extend its life into the computer age.

I think a comparison between the Legato and the HiFace is unfair to the HiFace -- it isn't really built to compete (and costs about 1/3 as much). The HiFace EVO may be a better comparison, but is too new to know.

Thanks for the clarification. I wan't trying so much to compare the hiFace to the Legato as to determine the relative importance of the power supply and the jitter reduction using a crystal oscillator ( which I remember from ham radio in 1960).
I find the strengths of the hiFace/Theta Gen Va to be the reduction in glare that you cite as a weakness, so I guess I should attempt to find a Legato or upgrade power to the hiFace.

I would (and did) get the Legato -- twice. I have two systems (the other is a Casablanca II Xtreme) and I use Legatos with both. My experience getting decent computer sound was the same with both -- I didn't like what I heard until I got a high-quality asynch USB/SPDIF converter.

Novice at PC Music Storage/ Downloading. I am currently having a Computer designed from bottom up. This Computer will be utilizing USB 3.0, as well as USB 2.0. Heard that they were compatable anyways. Trying to plan ahead for a USB to SPDIF,AES/EBU Converter to hook up to my favorite DAC. Any Converters out there that can utilize the benefits of USB 3.0? Any Converters out there, including the ones mentioned here, with a built in USB 3.0 Reciever? Any sonic benefits to utilizing USB 3.0? Any experiences with High Resolution, HD, Multi-Channel, across USB 3.0?
