Marantz is not warm unless you compare it to Yamaha. It is neutral. The B&K is slightly bright and grainy but not extreme. Rotel would be a little warmer and Parasound much warmer.
Everything is based on perspective. Klipsch are extremely bright and harsh so to Willand it does make Marantz seem warm.
