Now I get it...

I re-read what I wrote above, and I realize it's possibly confusing, so kudos to Uber for more or less getting my idea.  Here's a better way to say it:  Over the decades, I have developed some biases regarding record labels.  For example, I don't expect much in the way of top notch SQ from Atlantic jazz LPs.  The sound tends toward the muddy and dull.  Roulette LPs are usually unlistenable, shrill and tinny sounding.  Tragic that much of Sarah Vaughn's ouvre is recorded on Roulette.  I've always also felt that Blue Note is over-rated, sort of like the Atlantic sound with muddy bass, at least sometimes.  In my current set-up, I have 3 cartridges on 3 different tonearms feeding two different systems, on which all those labels are not only tolerable, in some cases I sit there thinking why is this sounding so great?  A fourth tonearm/cartridge combination does not give me such a thrill, although on well recorded LPs it sounds fine enough. In the preceding several months I was running the very same set of 4 cartridges but mated differently to the same 4 tonearms, with much less "magic". My personal oddysey with all this equipment seems to be telling me that one should think of the tonearm and cartridge as a closed system.  If you can find a pairing that interact synergistically there can be a sort of magic that does not necessarily happen if you just mate an "expensive" tonearm with an expensive cartridge, which if done blindly can be very underwhelming.

Guys, I appreciate your thoughtful responses.  I think in my original post I should have flipped the narrative to say that I am amazed about just how awesome some of my records sound.  With my new set-up I am astounded about how some of my albums just make me go "Holy S***!"  While the others, most often the reissue 180 gram "audiophile pressings", are enjoyable but sound less alive.  There are exceptions to that rule, of course, but I think you all understand.  In other words, I now finally get the value of consideration paid in searching out really good vinyl.  Steve Hoffman forums have become my friend when looking for these reviews. YMMV.  Am I having fun?  Heck yes! 

Jerry,

Did you mention which speakers you use?

I too recently bought the same amp but at the
same time started a remodel of my listening room
so all the gear is packed into my office. Nearly done
with the work and can't wait to get it hooked up again.

Congrats on the new system!!

Jerry, I am an analog guy since the early 1970s.  I play CD in my car (and I do have a bad-ass car audio system) but probably will get streaming and a quality DAC next year.  I have bought a variety of high quality audio systems over the years and for the past 1 1/2 years have been creating the best system of my life.  I recently added a new Rega Planar 10 and a Lyra Delos phono cartridge (rather then the Rega cartridge) and it far surpasses the performance of my last deck.  I am quite certain the Manley Chinook phono stage and my BAT preamp & amp play a tremendous role in it all, as does the upper-end Audioquest signal cables, power cables, speaker cable, and power conditioner.  A system is just that, a system.  Mating some nicely matched components delivers a wonderful experience. The joy of vinyl is really quite something special.  When you sit in "the sweet spot" and just about fall into the music, and it's very 3-dimensional, almost holographic, there is nothing like it.  I have never heard streaming music do that.  Maybe it is capable, but I have not yet received that demonstration.  Steve Hoffman forums are very helpful on the subject of SQ for your particular albums of search, no doubt.  I will disagree with tablejocky, though, about avoiding reissues.  There are plenty that are a waste of money, no doubt about that.  But, there are so many that are spectacular and will provide that magical moment for you.  Just a few examples; Stevie Ray Vaughan, In Step (Analogue Productions and Quality Record Pressings), Paul Simon, Graceland (25th Anniversary Edition and RTI pressing), Carole King, Tapestry (Mobile fidelity Original Master Recording), Joni Mitchel, Blue, Jeff Beck, Blow By Blow (Analogue Productions and Quality Record Pressings, 45 RPM). 

There are so many more that sound so incredible, they can bring tears to your eyes.
Enjoy the journey and welcome to the wonderful world of vinyl.

Sometimes bad recordings can have endearing qualities that you will eventually recognize.
