Comparison of sonic qualities of some tonearms
To "compare" arms, one needs a 2/3 arm setup with similar cart, plugged into multi input phonostage-both arms on LP playing. Now you can start talkin... If there's someone who actually does that, I'm envious you have the time/resources for such ... 
Visit to Mike Lavigne's house
Good read. You can hear a great setup even on a cell phone. ML's setup if one of the few you can just look at and expect great things. Ella's version of Misty was a good choice. I take the 1960 LP soundtrack-"Let No Man Write My Epitaph" to dem... 
Question about adjusting the balance
Don't  be put off by "lopsided" speaker placement to achieve center focus of the stereo image.     Your hearing and gear are not perfect (L/R balance) Imagine adjusting binoculars. The alternative is full techie absolute- mic/software, laser po... 
VPI Prime Sig/Lyra Delos / Feedback!
Ralph@atmasphere or someone technical needs to chime on  this one. Curious to read their take.  
VPI Prime Sig/Lyra Delos / Feedback!
"guess it wouldn't hurt to pick up the Fatboy Gimbal & A/B.." I thought  the gimbal was standard  on Prime Signature? Guess not. My Lyra experiences were with the low tech uni pivot.  Good luck finding what the culprit is.  
VPI Prime Sig/Lyra Delos / Feedback!
"funny how VPI and also Lyra recommend this cartridge with the table and the arm I have" File this under "on paper it's  not supposed to work, but it might" category. I've heard more than a few Lyra on VPI's, and they all seemed to sound good. ... 
A Big Shout out to TAP Electronics
Great to hear about another resource for competent repair. I'm in Long Beach-half hour away. Thanks for bringing attention to Tap Electronics.  
Most impactful for playing soft
Listening in Ultralinear is NO CO$T and should be about headphones? The PL has a good headphone section.  Longtime PL user here. KT 150's will give a more impactful sound, which might be noticed during low level listening. As mentioned-...

Humminguru record cleaner
"I have enough invested in my record collection to justify a Degritter but I have yet to find compelling evidence that it does the job that much better than the HG to justify the price. With the $3K I’ve saved I buy better copies of favorite recor... 
The $10,000 Question
"Prima Luna Dialogue One amp." Why not spare yourself the audiophool neurosis and get a used Evo series integrated or Dialogue Premium pre/amp separates? No suggestion on speaker. Too many great choices. Longtime PL user here.  
Technics SL-1200GAE or VPI HW-40 or …?
The OP just got the THE BEST reference (billstevenson)for his query with the above response.    
Technics SL-1200GAE or VPI HW-40 or …?
I've seen used HW's for  $10k, but you'll have to be  on  high alert for those deals. HW40 would be my choice as an overall package-performance/aesthetic.  Technics better value? I use a VPI Classic and I like traditional look of the HW.    
Signal tube versus power tube, sound impact?
  Likely only 1 preamp gain tube  in each channel will make a noticeable SQ difference. Could be subtle or quite noticeable. If your amp accepts different model tubes-EL34 for example, it will be a noticeable move. YMMV, but typically enhanced m... 
Upgrading from a VPI Aries 1- is it worth it?
If you decide on a new arm, may as well get speed control taken care of also. Sota Total Eclipse more accurate than VPI ADS-if you don't already have it.
