Recommend me a warm sounding 5 channel power amp

hi, i recently purchased a pair of monitor audio floorstanding speakers that i mated to a marantz 7007 receiver (used as a preamp in this scenario) and a rotel rmb 1095 power amplifier.
Anyhow, today i wanted to experiment to see how the speakers sounded when connected to the marantz unit and i actually liked the sound better that i heard from the marantz when compared to the rotel power amp. I find it more laid back and THAT is exactly why i am starting this thread. I want to purchase another amplifier and so far i have narrowed it down to the nad M25 or the parasound halo a52.
i would like everyone's recommendation on a warm sounding 5 channel power amp under $1500...
I have also thought about ATI, LEXICON,B&K COMPONENTS, but i dont have first hand experience with these...
Anyhow, let me hear any recommendations you might have :)

thank you
