Selling this for a friend, because he sent it to me for diagnosis; as we both have the same set-up: Auralic Aries Mini, to this Mytek Brooklyn.
He felt it was "malfunctioning", based on some unusual output...and wanted me to insert it into my system, and see if I could get to the bottom of it (I am in IT, and Hardware troubleshooting is routine for me).
First thing I did, was update his VERY outdated firmware; he was on 2.07, where the latest is 2.21. Once I did that, and put it in my system...it sounded fine; great of course, just like mine.
However...then I noticed; not "unusual" output; but no output at all, after running in the system for about an hour. I could tell, the DAC was still getting a signal...because I could see the input meters functioning; but no output to pre-amp.
After fiddling...I am 99.99% positive; I have isolated the issue. It seems...that after a certain amount of time (1st time, it was ~1 hour...next, almost ~4; so it's likely due to the unit heating up); the MQA malfunctions.
There is no output, with the MQA enabled; but as soon as you disable it...everything is fine and perfect again. With the MQA disabled, I have run the DAC ALL DAY, without loss of output signal. (I have have tested, with USB and coax s/pdif inputs; same issue with both. Can't speak for TOSlink).
Now...there's a chance; this issue, might get fixed down the road...with a firmware upgrade. But of course, no guarantees; as the issue might be hardware related. And you won't be able to get it repaired, under warranty anyway; because as the second owner...warranty does not transfer.
So...why buy this DAC? Well...if you don't know, what MQA is; don't care what MQA is...don't plan, on ever caring what MQA is...lol. You get a great DAC, at whatever fraction of the price...the auction terminates at. Or...chances are, you could get it repaired; and even that, plus the cost of the DAC...still leave you in the black! (Or...you might always try raising hell with Mytek, and seeing if that gets you anywhere. You know...the squeaky-wheel-getting-the-grease approach ;)
Other than that...not much more, to say about the performance of the Brooklyn. Reviews proclaim it to be, as good or the best...at its price-point and above. I've owned a LOT of DACs; and I can't disagree.
If you have any specific questions, I'll let you ask them in PM. S&H and any payment fees, are NOT included in the final auction price.
