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

Don't know the NAD, but I traded out my Audio Research gear for an A-52 amp and I love it, very warm (not dull) and can listen to it for hours. I suspect its biased fairly heavily into class A as it puts out a fair amount of heat.
Monitor Audio is a brand which makes exeptional good crossovers. Wenn you use the right amps you can create depth and even a 3-dimensional stage. Marantz is a 2-dimensional brand. You only can create depth wenn you use an amp and pre amp as weel which can give depth. I sold a lot of Monitor Audio. I also give shows with Monitor Audio. I tested many amps with Monitor Audio to see if the amp is a 2-dimensional ore 3-dimensional amp. Onkyo is the only brand in his price tag who can give depth. I sold it a lot with monitor Audio. Primare is also a warm sounding amp with a 3-dimensional image. Many of my customers use Onkyo with Primare. These two brands are superior to Marantz with Monitor Audio. For me it is that simple!
