What source and amplification would you use to drive KEF LS50 speakers?

[DZetye]

I use a pair of LS50's with an Auralic Mini and a NAD D3020 and it is plenty loud enough in a 14x25' room. In fact, I would venture to say it rivals the best systems I have heard in this room which included a $10K Audio Research system with Vandersteen 2Sigs. I use a Geek Pulse Infinity DAC with a USB output from the Mini and a pair of Regens with a Curious Cable link. You might be surprised what 30-40 watts will do with the KEFs.
