@kozzmo I believe you should keep your idler and add to it. By that, I mean that I think everyone who’s serious about vinyl should own one of each genre, i.e., idler, belt, direct drive. For my belt, I own a Clearaudio Innovation Wood with 12” Universal tone arm. For my direct drive, I own a SP10mkii beautifully rebuilt, including power supply, in a massive sapelle plinth by Peter Noerbaek of PBN Audio with a 12” Sorane ZA tonearm (I purchased this deck from Rob Wyatt who commissioned it for the 2018 New York Audio Show to compare an original SP10 with the debut of the SP10R). And my next purchase will be either a 301 or 401 so I’ll have the idler genre covered.
I believe each of the turntable genres has something unique to offer for the type of music being played, the way it was recorded/mastered, etc. This is just my approach and to offer an alternative way for you to think about your situation. -cheers!
