Bought the three part system from Denon NA HQ back in 1995 I believe. They are built to last and the sound is very warm and expansive. They have incredible power as I run a pair of 3.8ohm speakers. Denon built these as a special project for those audiophiles that couldn't afford their reference S1's at $20,000 US/each. The S10 amps are well matched to the S10 pre-amp but sound wonderful with any good pre-amp. These are workhorses and well worth picking up for the long-term.
