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

Mrtennis,
Please let us know when you hear the Stibbert in your system so as to make a more valid assumption.
Everything differs to peoples taste but comparisons need to be made in peoples own systems.
Many Regards,Bob
I'd love to hear from those who have compared the Stibbert with the Bluenote Koala? I've read all the reviews I could find from searching and many seem to think the Koala is quite close sounding to the Stibbert. Others think the Stibbert bests the Koala by a longshot. Hmmm.

As far as the Resolution Opus 21 goes, I would LOVE to hear one. I am encouraged by the thread about the GNSC Mods to the Opus 21. That is quite compelling.
I have the GNSC Reference Mod Opus 21 and it is really special, call and talk to Steve, he's a great guy and will shoot straight with you about any player...
For $3500 (or less), you could get a used Exemplar or APL modified Denon. I highly recommend that you consider this route. Note: I am not selling either player (or any gear). Good luck!
