Suitable amplifier for NOS DAC, any experience


I use R2R NOS DAC. This type of DAC's have images on analogue output.
DAC output filtered with Capacitor and have -6db roll-off from 25KHz so images are significant.

I would like to build power amplifier and connect them directly to DAC output.
So just R2R DAC resistors, capacitor and power amplifier.

Does someone have experience and knows what important parameters should conform power amplifier ?
Doesn't AYA DAC have a passive filter after the DAC?

Some classD amps are rather sensitive to out-of-band signals - I seem to recall Hypex n-Core may well be one of them. Perhaps use a classAB with good HF distortion figures? Alternatively use a filter after your DAC to suppress images.
