G'day all, this is an interesting thread! Doing quite a lot of DIY stuff myself (including moving magnet cartridge phono stages) for many years now, I've come to regard op amps very highly indeed, something that I probably would not have said ten or so years ago!Op amps can have 'issues', but as with all circuit designs, it takes a very good design and implementation to show op amps at their best. At the moment my phono stage of listening choice is a simple single op amp based full feedback (kit) design with a few unremarkable component replacements and it sounds very nice indeed with nothing to complain about at all.
It delivers around 40 db of low distortion and (very) low noise RIAA equalisation voltage gain and it sounds great, which is precisely what it is supposed to do. Regards, Felix.

For me it was witnessing what a GSP ERA Gold V phono stage could do. That has to be more than 10 years.
My monoblocks use very high power opAmps, a Blue Circle design of about a decade ago or more (same devices used in their longstanding series 200 power amps).
Never trust an Atom, they Make Up everything!
just sayin', not makin' it up either.dee
