In my dining room I have a desk PC that also acts as a music server throughout (esp.) in the lounge which has large amounts of ripped .flac on & also listen to Spotify on it - At the moment I've got an inexpensive exterior DAC running through a Cambridge Topaz 20 watt amp & a pair of JBL Control 1's on this PC system - It sounds OK & I spend a fair amount of time listening to it as I work on the PC & I'd like to change the amp to something slightly better than the Topaz & with more power, preferably to something I can get used of auction sites as I also want a new set of wheels? Any ideas please? I'm not expecting wonders from the Control 1's but I feel they can sound slightly better.
