Many thanks for the positive comments, all!!
Since I posted this thread I've been severely enjoying the music and - mercifully - not craving new audio gear or upgrades. No new revelations in this time, but a couple more insights:
1) I've noticed that good vinyl really accentuates and enhances the individual strengths of different headphones. I've enjoyed the L3000's driving power with Iron Maiden, Jethro Tull, and Dire Straits. The HD650's soundstage was sublimely expansive and enveloping with the recent Tori Amos and New Order albums. The Qualia 010 was truly holographic, transparent in its reproduction of an opera (
Lucia di Lammermoor, featuring a young Pavarotti). A wide range of genres rendered impeccably by a single source...I just need to match the headphone & amp to the desired experience
The downstream gear I've been using recently:
L3000 & SDS for rock & metal
HD650 w/ Zu & Rudistor RP7b for newer pop
Qualia 010 w/ stock cable & Rudistor for classical/opera
Haven't found a solid niche for the vintage RS-1 yet, though they do sound nice. Need to try the JVC DX1000 with vinyl and see what they can do.
2) I got my cleaning rig set up and it does make a difference in the noise floor - some discs more than others. I use a VPI 16.5 vacuum cleaner with TTVJ's Vinyl Zyme, a couple zaps from a Milty Zerostat after cleaning, and a new poly-lined sleeve tops off the process. I also now use an Onzo Zerodust to clean the stylus every few records. With new vinyl, and especially well cared for used vinyl, you can almost completely eliminate the static pops & ticks. As I mentioned before the noise floor was never a big issue with me, but still, the lower the better! I also feel good knowing that clean records should last much longer (I rest vinyl for at least 6 hours after play as an additional precaution).
3) As mentioned by countless others, the mindset one has when playing vinyl is different than with CD. Once the needle drops, I'm very likely to get lost into that side of music until the last bit of groove. With CD, it was far to tempting to skip around to my current favorite tracks, skip over a meandering intro, or skip right to the next track as a song was winding down. With vinyl I'm far more...relaxed, and able to soak up the album as the artist probably intended. When you're willing to accept something exactly as-is, you're far more likely to find the hidden gems within
Or you could also say - after all that cleaning/setup ritual with each disc, you're itching to hear some serious tunes before going through it all again!
Curses, I need money for more records!!!
