Cheers, chaps. Quite simply, I know that it works!

There's no doubt that properly implemented 1541s sound as 'analogue' (in the right way), as you're going to get with digital. Multi-bit, done properly, IMO, has always outperformed bitstream, in the musicality stakes.

Unfortunately, it was technology that became 'forgotten' by the materialistic ravages of commercialism, back in the day, (much like Betamax did with VHS), despite the former being superior. However, Andrew is right, it takes experience and know-how to fully exploit TDA-1541s, but once done, and you hear just what they're capable of sonically and musically, there's no going back to 'frigid' sounding bitstream....
