With regard to issue three, I think it is system specific in my case. You can perhaps check with other people here who have the Aquarius.
My question is: why do you pick the terminator over the Aquarius if the terminator will be the slower DAC?
I don’t think Sandu meant that the T+ is slower than Aquarius, rather slower than other hi-end dacs. The T+ is in a different class than the Aquarius. I would choose the T+ as an upgrade because it is in the price range I could afford (willing to pay) buying used.
My impressions are based on Sandus´ reviews. If he is wrong with regard to the T+ then perhaps someone could correct him. However, you have a point, Sandu should have mentioned the dacs that were better than the T+.
"I’ve already covered quite a few R-2R ladder DACs by now, some of them were magnificent sounding like Denafrips Venus, Audio-GD R7 and Musician Aquarius. All of them had their pluses and minuses, but I feel that today’s unit terminates them all, climbing an aluminum throne as the best sounding DAC I had the pleasure of testing at my place."
"The amount of information that comes forward is staggering and as much as I liked the Musician Aquarius and that yummy sounding Rockna Wavelight, Terminator Plus goes a little higher, delivering a clearer, a punchier and a faster overall performance."
"Terminator Plus reigns supreme in here, closely followed by a Rockna Wavelight, Musician Aquarius, Audio-GD R7 and Denafrips Venus."
