The problem is the right channel on the amp sounds - for want of some better words - dulled, muted, veiled...you get the idea. The left channel sounds quite detailed and bright. Sitting back in my usual position you could hardly tell, but then up close there's a difference and when checking the output on the channel balance it was clear. You could say "well, just sit in the usual place" but that's, as we all know, not that easy now; the scab's been picked, you know it's there!
In truth, having spent about £300 on it, I could have been on the way to the NAD C355 with £50 in my pocket left over, 3/4 of the way to Yamaha's A-S700, 2/3rds of the way to the Genelecs I heard on Sunday, and so on and so forth - you get the idea.
The Sansui amp sounds terrific, no doubt, while the 217 is playing Hotel California and I might stick with that for the time being. Warmed up after half an hour or so, and with a good recording the system really sings (found an early US copy of HC in one of the Record and Tape Exchange shops and it's a winner). But, like I said to d_a_n-1979 on another thread, I know the 752s have better in them than the 217 brings out.
I get the idea with the older kit, and in fairness too, there is a shop in Edinburgh called Retro Reproduction that I really rate. The guy in there (Graham) has let me try out various bits of kit over recent years, but I began to feel the more I tried out various amps and not bought any of them he might get a bit cheesed off, however, they do have some bits in that I might be keen to try - assuming I'm still welcome through the door!
