100 watts amp suggestion?

The Qinpu A-1.0x integrated amp puts out 100 watts per channel into 8 ohms and 160 wpc into 4 ohms. Its price is low enough to leave over a good part of your budget for a DAC and cables.

One DAC to consider would be the Moon 100D, and good budget cables could come from Atlas ( Element and Compass digital ) or Audiogoner Joe Mazzaglia's Auricle Audio Design ( Encore and Encore Signature digital ).

When you buy your digital cable, no matter which it is, make sure it is 1.5 meters long.

Thanks Tobias, very helpful your advice, I will be looking into that tonight.

This is a link with speakers specifications, thanks

I have had Creek Destiny integrated with my SA2K Master speakers for a long time, and I ain't looking anywhere else...I'd recommend an audition.
