At a slight tangent here: a dozen or more years ago, when I was starting to get very serious about my hi-fi, I bought a Luxman SQ1220 amp - it stayed with me for quite some time when all other boxes were swapped with monotonous regularity!
Fast forward to earlier this year: now married and having settled stopped chasing the pot of gold at the end of the high end rainbow, I'd settled into a comfortable life with a 'music playing system' but the urge to listen was waning (we're talking approx. £1k amp, same for CD here, so not bad kit).
As I'm sure many do, I did a quick recce of eBay and found a Luxman SQ507x up for auction... to cut a long story short, I didn't win the auction but something sparked.
Two/three months later, scanning eBay again and the same amp is being listed: this time I win the auction.
The amp has been with me for about a month now and is used every day - I'm listening as much now as I ever did. What 'Colin2040' says above echoes how I feel - ignore the facilities, sit back and enjoy the music. Certainly very close to (if not) the best sounds I've ever had, too.
This from a late 1960's to early/mid 1970's amplifier... my point being that Luxman amps not only sound great but are built to last.
Would definitely go for it if you like what it does - you may never need another amp!
