Aqua is well broken in by now.
Thanks for the Mojo suggestion. As it happens, I was all set to replace the Aqua with a Mojo but Benjamin expressed concern about my transport, so I bought the Jay's instead (couldn't afford both).
How to proceed?
Removing my Aqua La Voce dac from my system has eliminated fatigue and reduced but not fully eliminated sibilance. Running my Jay’s CDT2MKIII into my Hegel H390’s onboard dac is definitely a more relaxed presentation but tonally leaner than I prefer. Some have suggested I swap out the Hegel, but first I’d like to try another dac.
What I’m unclear about is how to go about choosing another dac that will not duplicate the same drawbacks I’ve experienced with the Aqua. Are there details in the design or specs that can guide me in this regard? I'm unsure how to proceed.
I vaguely recalled a similar comment and looked back a few years to try and locate when folks were comparing the S2 vs. S3 versions of the La Voce dacs, and found members on another forum changing out caps in the S2 in an attempt to tame some of that with Jupiter Beez Wax caps and such. Not sure how it turned out. Maybe something there worth following up on to learn more.

I checked out your system page to get an idea of your room- beautiful house! Your options for speaker placement don’t seem to be working in your favor though. The open doorway behind your left speaker and the right speaker almost in a corner are enough to cause issue. Not sure how WAF plays into your situation but have you considered rotating your monitors 90 clockwise? Just as an experiment have you tried placing light acoustic materials around the various surfaces in your listening room just see what effects it may have? |
Looking at your system and the comments, I assume that the sibilance was not an issue with the Wells and Moon setup? The Aqua is a pretty nice unit, I would be surprised that it is the source of the problem. Possibly it is making it more apparent, and the Hegel DAC smooths it over a bit. Playing Devil's Advocate, have you tried replacing the source (Jay's) with something else to see if the problem persists? I also thought to suggest bypassing the Hegel preamp, but looking at the back side it does not look like that can be done with this integrated. |
Perhaps @grannyring has some experience with such mods? Unfortunately, changing speaker location is not an option. When we built the house, I was just beginning my audio journey. Aside from providing a space for components, I gave audio very little thought. The dac in the Hegel does not sound rolled off to my ears. If there is any attenuation, it’s in the mids -- there’s an overall lean quality that I’d prefer was not present. But the main difference I experience, having gone from having the Aqua in the system to listening to the Hegel’s dac several times, is the sense of ease and relief, as though I’ve unconsciously been holding my breath with the Aqua and can suddenly breathe freely when the Hegel’s dac is engaged. It’s not subtle. However, it does seem counterintuitive. I’d expect an r2r dac to be more relaxing. I have experimented to some degree with covering the glass-topped coffee table, the glass-doored Craftsman bookcase and the tile hearth with fabric and foam dog beds. I’ve heard no difference. Nor does closing the drapes impact the SQ, as far as I can tell. FWIW, according to two experienced audiophile biddies, I have pretty good ears. it's not clear to me why you would assume the Border Patrol would constitute a backwards step, but then, I've yet to hear it. My only impressions are derived from reviews. You are correct -- no sibilance with Wells and Simaudio. As an experiment, I tried swapping in an old Jolida CDP as a transport but the sibilance was even worse. I also inserted the Aqua into the Hegel’s loop function, in which it takes over clocking functions and the sibilance was worse than using the Aqua without dac loop.
