The Darko review of the s500 is very compelling. 25hz all in one and €25 to demo for 45 days.i think this very good value too but that won't resonate with some out there. Considering you are getting streamer, dac, actives, room correction, tuning possibilities... its impressive.
I've no doubt many of us could put together a muddle of boxes for slightly less that might sound better but think of the the WAF with these babies!
Having tried a lyngdorf 2170 (D-class amp + dac + room correction) recently I was disappointed compared to my current setup. If I could stop swapping boxes the S500 might just do it...
