Connected the MinDSP Flex up to my Audiophonics LPA-S500NC (Hypex Ncore NC502MP) today.
Analog version, 6.35mm jack (TRX) to XLR balanced. USB input from my Macbook and toslink from my PC.
Perfect. Nice clear display, good volume control, good remote.
And with my ear pressed to the tweeter (B&W CM10 S2) only a barely audible hiss. In my opinion very good for low cost products, amp with a gain of 25.6dB and rather sensitive speakers at 90dB/W/m.
Very satisfied with my new setup.
The DIRAC license has yet to be activated, so I might post about this later.
