I have a Garrard SP.25 Mkll turntable which I shall be using in conjunction with a NAD 326BEE amplifier and B&W 684 loudspeakers. Which phono amp will be suitable for the turntable? Also which cartridge will be appropriate for the turntable ? Is it worthwhile investing to that extent in a turntable of that vintage? The turntable has some sentimental value for me. Or will the wise thing be to replace the turntable with something new, in which case what price is the Garrard likely to fetch if I sell it?
