Just how high-resolution is vinyl?

I just moved things around in my system a little bit. Nothing major, shortening lengths, making sure everything's tight, improving shielding, adding a... um... top of the heap isolation pad...  I'm about to give my reflex C loaner back and I wanted to make sure I was hearing all I could out of it. My system is pretty well set up for detail retrieval. I always erred on the side of resolution because I was otherwise using high-res digital sources. Current setup is: LOMC p-mount, a stock Technics 310MC, linear TT, Technics SL-6 (the ugly one). Then Reflex C, 6F8G buffer (this is my volume control), single-ended amp, full range drivers. There's also two sealed passive subs with their own amps.

Terrific answer, thank you. I remember 35mm, and was happy to see some younger people using it on a walk the other day.  Of course my father was a large-format photographer, plates the size of my hand, out in a field with a black cloth over his head. No truck with this modern stuff! This though, I think he would have appreciated. 

Yes but not products in direct competition with HFC so speakers are okay I think.

Ah, great. The speakers are my (or rather my wife's) Blumenstein Orcas. I bought them used because the cabinets were pretty. They were literally my first hi-fi purchase (I had to ask if they were the kind that needs an amplifier) but every time I level up my understanding of audio I gain more appreciation for just what a brilliant implementation of the 3" Fostex driver it is. The guy who designs and builds them is a real throwback - just thinking about the physics and then chasing down the interesting ideas with experimentation. His website has some really interesting ideas on it. Obviously, they beautifully handled the very subtle layer of information described above. So, hat tip Clark. Highly recommended.
