I'm sure this has been discussed ad nauseam but I can't find a specific thread... How is it that 40 years ago when there was no digital, every amp came with a phono stage in the price - and now it seems they're so expensive that they have to be provided separately at vast cost. Is there really so much difference between a phono stage in a very good amp you can buy for 400 quid or so from the 70's to a modern separate which costs at least that in addition to your line only amplifier?
