What to upgrade from Bluenote Koala? $3500 ish


I am thinking about upgrading from my BlueNote Koala Tube CD Player. I've done A-B comparisons to Audio Reseach CD3 MKII, BAT VK-D5 and Lector CDT.7. Each of those players resolved detail in a more musical way to my ears, and had a deeper more hologaphic soundstage. The Bluenote Koala is very dynamic, but has a rather forward solid state sound to it, albeit very musical. It is wonderful, but when I did the A-B tests, it was bested. I listen to jazz, Singer/Songwriter, blues, Rock. Artists such as: Keb'mo, Nora Jones, Diana Krall, Bruce Cokcburn, Amos Lee, James Blunt, James Taylor, Sting, Aaron Neville, Larry Carlton, Rippingtons, Russ Freeman, Brian Bromberg etc. Hence my search. I'd like to spend no more than $3500 or so. Here is my short list, new and used:

Cary 306/200 (Can't afford the 306SACD)
Cary 303/300
Audio Research CD3 MKII
BAT VK-D5 0r VK-D5SE
Resolution Opus 21
Rega Saturn
Dare I consider the new Shanling CD-T1500 or Raysonic CD128

My System:
Audio Research Vsi55 Tube Integrated
Proac Response 3.5 Floor standing Speakers
BlueNote Koala Tube CD Player (Sovtek 6922's)
Acoustic Zen Satori Shotgun Speaker cables
Acoustic Zen Silver Ref II IC
Running Springs JACO Power Conditioner
Wireworld Silver Electra 5/2 PC on BlueNote Koala
Black Sand Silver Ref V/Oyaide 046 PC on ARC Integrated
Oyaide XXX AC Wall socket with Carbon fiber Mounting plate
FIM Isoltation roller blocks under components
Dedicated audio Acrylic Cable lifters
128x128groberts3
Does the Rega Saturn even compete in the arena we are discussing? There were a lot of posts about it in 2006, but I haven't seen much more since then.
hi hiernote:

what you are saying is that you prefer truth over beauty.
that is your opinion and it is a fact.
Hiernote,
Thank you for your comprehensive post regarding the two players. It is far more than I expected and it is very much appreciated. Are there any other CD players in this price range that you even like better than the Stibbert? Bob
I'm about to pull the trigger on a BAT VK-D5 with Amperex tubes. Other alternatives are the McCormack UDP-1 which I've read good things about, or a used Audio Research CD3 MKII. Can anyone give me opinions on these, perhaps compared to the Bluenote CD players? Koala or Stibbert? Or even Lector CDT.7?
i owned the bat cd player for a while. i ytried mullard and amerex tubes. this cd player is not receptive to changes in tubes. the player is very transparent, detailed and unforgiving of poorly recorded cds. it is closer to the truth than to beauty. it has a little extra energy in the brightness region (1000 to 3000 hz).

i sold mine. why not wait for the new prima luna prologue 8 or the arcana cd 1.0 and cd 2.0 .
