Hegel H390 DAC

@mm1tt77 Thanks. A good USB cable to try is DH Labs Mirage. Very good at a reasonable price.

I was hoping you’d post here. Thanks.

I used digital bnc from Jay’s cdt2mklll to Aqua and rca"s from Aqua to Hegel.

I used same bnc from Jay’s directly into Hegel.

Sorry, but are you suggesting using DAC loop would equate to "equal footing" or the opposite? I did not use DAC loop, in any event, as I have only one digital cable and loop would require two.

This comparison really surprised me. The results were not at all what I expected. With the Aqua, I experience fatigue and sibilance. These disappear when Hegel’s DAC is utilized. I tried the Hegel’s DAC as an experiment to see whether these unwanted factors were traceable to the Aqua.

@stuartk

i did not realize you are solely listening to cd’s played through jay’s cd-t, and you are in fact not streaming music (is this understanding correct?)

before you try different dacs, as mentioned by a couple others, i would suggest a couple (cheaper and easier) things... get another bnc cable to try the dac loop, and also, try a different set of ic’s (and use the balanced inputs) from the aqua to the 390 - i have found the analog balanced in’s sound a touch better than the rca’s on the bigger hegels -- looks like the aqua has dual mono topology through its d/a to the outputs, so best to take advantage of that

as many dacs as i have tried, i have never had an aqua la voce unit, but by the specs this should be quite a natural (and not a strident) sounding unit, and should surpass the internal 390 dac by at least a little

i have plenty of extra cables i can send you if you’d like, just pm me

good luck have fun

@jjss49

Yes, sir -- only CDs for me!

Thanks for your generosity in taking the time to look into the Aqua's topology, for the tips on cabling and last but not least, your kind offer re: cable loan.

(FYI, the DAC Loop requires two bnc cables and one XLR -- no rca’s).

In order to minimize variables, I plan to order a duplicate of the Audio Art Statement digital cable that’s currently running from the Jay’s to the Hegel and a pair of the Statement XLRs. I can return them if this experiment fails to yield good results.

I will report back once I’ve gotten everything hooked up and listened. I’m hopeful this will solve the fatigue and sibilance issues. If it does not, then borrowing some other cables could reveal whether my current cabling is problematic.

Thanks for your Kimber suggestion. 

The Hegel's DAC loop requires two digital bnc cables and one XLR. I must use XLR for it to work.
