Rotel or B&K, who's warmer?

I have posed amp questions before for my Paradigm Studio 60v.2 and got some real good suggestions, but all of these have been out of my current price range. Many suggested Anthem, Bryston, and McCormack which I wish that I could afford. I just recently purchased a pair of new Paradigm Studio 40v.3 speakers for my new house. I find the new v.3 speakers to sound brighter or more tinny than my v.2 speakers. I real dislike brightness in my music. I am going to use my Denon 3802 receiver to run my surounds and patio speakers and as a processor for HT use, but I it's sound with the ST 40v.3 to be too bright. And yes, I have broken them in for well over 200 hours. I want to add a 3ch amp to give the 40v.3 more power and hopefully a little warmth. I am buying used for cost considerations. I was wondering who had the warner sound, Rotel or B&K amps? I was specifically looking at the Rotel RB-993 (200w*3), B&K ST-1430 (125w*3), or the B&K ST-3140 (140w*3). Any suggestions on these or similarly priced 3ch amps would be helpful. I mostly listen to Widespread Panic, Greatful Dead, Neil Young, some Bluegrass, etc. I will also use the amp for HT.
thanks,
