Who is you go to for top quality vinyl

My gold standard is Analogue Productions closely followed by Speakers Corner and ORG. The 45 rpm APOs are something else again. I have their 45s of Ry Cooder and V.M. Bhatt's "A Meeting by the River, Nat King Cole's 1957 "After Midnight" and the RCA Living Stereo's "The Power of the Orchestra" doing Moussorgsky's "Pictures at an Exhibition" and "Night on Bald Mountain".

Hey Johnny I hear the Dire Straits and Fleetwood Mac 45 releases are great

That sure wouldn’t surprise me. The Analogue Productions’ 45s’ clarity, smoothness, dynamic range, and in-the-room sensation definitely raises the bar. Even the 1957 recording of "After Midnight" puts Nat King Cole in the room. It's one of my very best records for doing that even thgouh the original recording date was 59 years ago. It turns a stereo system into a virtual reality device and from there to a time machine on these old recordings by long gone artists.
