Cetainly Marantz amplification will give you a good clear sound, very detailed and open, which might be what you like for that kind of music. If you prefer something a little more warmer, then you could partner it with such a source. I've had the (now discontinued) PM6010-KI for a long time now and it's a great amp. Not sure what the 7003 will be like but it would be worth shortlisting. Can RS let you demo it in store?
NAD put out some great gear too - I still have my 3020A from 1986 and won't be parting with it on the breathing side of this mortal coil (my late dad bought it for me). The almost iron-curtain like look is less than inspiring to some, but that might not be an issue for you.
