audiophiles who are just getting the itch to upgrade

I hope for everyone's sake or we may all be selling our gear. Thanks for all the responses. So for final question, because funds are limited what TT upgrade to the Linn Sonedek lp12 would make the greatest positive difference; karousel, keel chassis or Lingo 2 power supply. Thank you 

@phill55 You are asking about upgrades to the Linn that have quite varied price points. A Lingo 2 power supply used is about the same price as the Karousel bearing, whereas the Keel chassis is about three times the price of those two ( if new). 
Since you already have a power supply upgrade ( the Herc board) although not that great, it is better than the stock power supply. Therefore, to my mind the most potential for better SQ comes with the bearing...and that is the Karousel upgrade. A lot less $$ than the Keel and a major part of any LP12. I am going to look into the Karousel myself, and i just updated my LP12 with a brand new Cirkus a couple of years ago! The Cirkus upgrade was very easily heard and a BIG uptick in SQ. 

@phill55 Just noticed that the new Karousel bearing probably will not work with your Herc power supply. It certainly won’t work with Valhalla and I strongly suspect that the same issue will apply with your Hercules!
Before making a purchase commitment to Karousel, I would check this out with your vendor. If the new bearing won’t work with Hercules ( now pretty sure it will not!), then the next step would be to look at a power supply upgrade...meaning take a look at Lingo 4...or Lingo 3 and then go to Karousel.

Thanks for all of your input daveyf. So help me understand why I wouldn't look at other turntables; used VPI or SME, etc.? I am into the Linn LP12 for $1,900 (bought used) with Koetsu black cartridge ($1,200 used). If I buy a Lingo 2 or 3 used @ $900, then Karousel bearing @ $1K then look buy used Linn Kore @ $850, I am into the turntable for $4,650 - $5850 including the cartridge. At this price point, I have to believe there are other TT's out there at this price range used that would be as good if not better than Linn? Any comments to the community? 

I’m a long time LP12 owner (since the 90’s); I really like my table, and it’s had updates over the years- I started with the Basik power supply, Rega arm and a Linn K9; now I have a Lingo power supply, Kore chassis, Ekos II arm, and Arkiv B cartridge, plus, a Trampolin and Silver T cable. I know there are other great tables available, but I’m not changing as I feel I’m deep into my LP12, and a Karousel is likely on the horizon. However, if I were not deep into an LP12, or didn’t have an LP12 at all, I might look and listen to a VPI Scout. I heard one  a couple of times, with a Grado cartridge, and I was mighty impressed by what I heard.
