I don't know your old DAC but sure I can tell you that with the new SU-9 my Elac Dbr-62s sound better and louder than my old DX7s. Both in the highs, mids and lows. Attention it is also true that I drive my elacs with an Hypex NC502MP ;)

Pls email [email protected], thank you, we'll help to check.
Thanks, I solved it, I asked and I should have sent it to have a product repaired even knowing that the problem was already known in April ..
So looking at the useless 99 on the Display, I preferred to ask for the refund from Amazon and I will avoid SMSL products

after all this mess, in 4 months, they never took the defective versions off the market, so it's probably defective.
The problem is they don't replace the faulty dacs with the updated ones, you have to return your dac to Amazon and then buy another one, this is insane. I measure mine and it was defective.

But is mine defective? Because I haven't tried to XLR yet, it works well in RCA.
But is the defect only in XLR that emits buzz?
