Warm Sounding Preamp Suggestions


I'm looking to dial down some mid/high glare from my newly acquired B&W 801 S2.  I'm getting a little fatigued and want to see if I can warm it up a bit with a preamp.   Right now I'm using a Yamaha Aventage Receiver and a Threshold S500/II. 

Any suggestions?  Tube preamps?

213runnin, I think the BAF's ability to extend, tighten, and articulate the base rounded out the 801's overall response, resulting in much, much less glare.


Not familiar with the speakers, but in answer to your basic question, you can never go wrong with an audible illusions modulus 3 preamp.
