When i added a Bryston 120 watt power amp to my 95 db sensitive top of the line Wharfedales everything improved - tighter bass punchy sound cleaner and tighter and less sluggish. This was actually a 5 watt downgrade because I had the top of the line Pioneer Elite Receiver rated at 125 watts RMS and distortion figures that rivalled the Bryston.

It's not about the watts and it's not strictly about the sensitivity rating. Plenty of speakers at 93db sensitivity and are not the least bit friendly to low powered amps. SET amps like stable loads - nothing wrong with a 4 ohm load if it doesn't dip and rise too much. My speakers are rated as 6 ohms but never dip under 5. If I remember correctly the 2.83V, 1m spec needs to be subtracted by 3db to be the same as the 1 watt 1 meter spec (not 100% sure so check on that). Remember for every 3db gain you need twice the amplifier power.

Florian - I'd be curious as to the Serial numbers of both the Kondo and the Conquests. The Conquests and Kageki amplifiers as well as all of the other AN amps that I have heard and the one I own and everyone else I know who has ever heard any of them hear absolutely no noise with any of these amplifiers - there may be a faulty connection and your friend should definitely have a repair outlet fix the issue.
