[QUOTE="ludo, post: 38575, member: 691"] I'll dip a cautious toe in, from a DIY perspective. SS. More economical, easier, lasts. I'm not very well informed about valves, but it seems to me from looking at others efforts, that 6DJ8 and friends would make a fair candidate for phono preamps. One of the more respected varieties of these will set one back some R150 - R200. That buys a good few of one helluva opamp. Or a nice bag of transistors, if one insists on doing it that way. Another advantage, is that with SS you get to use your stash of polystyrene caps in the filters, without fear of slowly cooking them. The SS power supply becomes cheaper, and easier to get hold of. No need for sockets, as there's no need for replacement with SS. Apparently low noise inputs for MC are not considered feasible with valves. It is the domain of horribly expensive transformers, or comparatively very cheap SS. One could extend this right down the chain to the power amp, but let me not, as then I can no longer claim to be cautious ;) [/QUOTE]
