Hi, I've recently bought a used DM601 S3.
Paired with my NAD 310, they sound a bit muded. Compared to my exisitign Denon SC-m37, they sounded much lively and expressive with more depth.

You guys know anything wrong with the setup? The DM602 recommends amp power of 25-100Watts but my NAD 310 only supply 20 watts. Will this damage my speakers? The max volume i tried so far is no more than 11 o'clock.
