I just listened a T743 with Image B25 and it was very nice. Full and warm, but also quite clean and detailed. At the same time I listened to Monitor Audio Gold GR10 with a Quad amp, but it wasn't very special. The same Quad amp with Quad 12L speakers was clearly better than the MA's. This is just my opinion and you should have your own. Listen to both and decide by what you hear. Personally I would pair the Marantz with JMlab Chorus S, B&W 600 or something similar.
Have you listened to marantz with MA bronze? if so how does it compare with nad/psb?
