If you want to save a bit of money look for a second hand PM6010 KI-Signature. Similar sound to the 7001 KI-Signature and should set you back less than a 6002. Record Spot has one and always seems to be very happy with it. I'm sure he'll give you the greater insight of someone who has owned the amp for several years...
Well, yep, I suppose I do mention it, or spring to Marantz's defence when fronted with "they're too bright / thin / etc" from time to time...!!
Putting aside that I like a clear and very detailed sound, the 6010KI makes a cracking used buy - you'll pick one up in good nick for roughly £100, maybe a bit more (£150 for a mint item?) maybe a bit less on a good day if you time it right. You get an amp that's got a stack of good reviews and works well with a very wide range of gear, plus one that's been tuned under Ken Ishiwata's midas touch.
As I mentioned in another thread, I've used this amp since 2001, it's been partnered with a Rega P3 turntable, Rega Elys and then later Audio Technica AT440MLa cartridges (both very different animals in terms of character), Mission 733i and more recently 752 speakers, other sources have included Linn Mimik, Kenwood DP7090, very briefly a Technics SLPG-580A and currently a Marantz SA7001-KI CD players. I think that covers about as wide a range of sonic characteristics as you'll get from a set of sources. Nothing fazes it. It'll happily go up to around 11 o'clock in terms of volume before sounding strained, that equates to very good listening levels in a typical room.
For me, it's a super amp; I wouldn't still be using it in 2009 if I hated it in 2001! Enough inputs (six I think) and a very good onboard MM phono stage. A decent upgraded toroidal transformer from the standard 6010OSE, copper rearplate, good hefty construction and this went on at £400 RRP. You get a very clear and detailed presentation, good bass and treble - a fine overall sound. 50 wpc too, which I find is put to good use. It's go loud, but no ridiculous levels. I get it up to 11o'clock easily enough, but more strains it (with my speakers).
Here's a link to the Marantz website; sadly, the linked WHF review of the day isn't available now, but the summary provided is pretty accurate.
