The Nautilus 804 sounds best with an Amplifier of at least 400-wpc into 4-ohms. I found excellent results with Krell. Also, make sure that you use a very good source component. I would look for a Disc Player with an "A+" or "A" rating to use with these very revealing Speakers. Anything less than the above will result in much frustration, believe me I know.
B&W N804
On one of my posts I mentioned that earlier this week I went to audition several speakers. The LINN ESPEK,PMC OB1,and the B&W 804's. The amp used for all three speakers was the LINN 2250. I know that the PMC's are well matched with Bryston amps and LINN matches their amps to their speakers but what about B&W. Aside from the Bryston and LINN amps my dealer also carries Anthem. I did at an earlier time hear the PMC/Bryston combo and found it quite good.
I'm new to the 2 channel audio world so my question is which of the three amps would best suit the B&W's. In the next few weeks I plan to revist and this time I'll bring my CDP(JoLida JD100a). Should I keep the amp/speaker combo's the same or should I insist that different speakers be connected to different amps.
Cheers
