Upgrade my CD player or futile effort?


I would appreciate you guys input. I listen to 90% vinyl  and 10% CDs due to a lot of new music I get into only comes out on CDs. My analog system sounds fantastic to my ears but unfortunately my digital falls short. My analog system consists of:
-VPI Classic 1 TT
-Lyra Kleos cart
-PS Audio Stellar phono preamp
-Prima Luna 100 preamp
-Parasound Halo A21+ amp
-PBN Montana XPS speakers
-Dual Rythmick
F-12 subs
My CD player is a Marantz CD6005 running through my analog system.
Compared to my vinyl, overall the sound from my CDs lacks the depth and definition in bass, comes short in the soundstage and overall space in presentation and does not have the
same clarity in treble.
If I rate my analog sound a 9, I would rate my digital CD a 7.
My question is, would I benefit from a better CD player, even so the CD6005 is no slouch, or am I gonna end up in a goose chase?
I realize my CDs may never sound as good as my vinyl, but I would try to improve it if you guys think it would be worth the effort. Are there really some outstanding CD players out there that can measure up to vinyl? Personal experiences only please, do not need sales pitches by equipment associations you may have never listened to. Also all my cabling and room setup is a 10 to me with the analog so I wouldn't change any of that for my CD player listening.  Thanks.

FWIW I am waiting on Esoteric K-05XD and the K-07XD SACD players which should be released in a couple of months.  Rave reviews for the K-01XD and the K-03XD which have been out for a couple of years now.  All the Esoteric models have among the best tray mechanisms in the world, and the new "XD" versions have a much-improved DAC.  So you get a phenomenal transport and a fantastic DAC all in one.  They have all kinds of digital inputs to use the DAC in the player.  For me, it's a no-brainer upgrade.  But first I'd like to demo when they come out.  Guessing in the $7500-10K range, so not cheap.  But again, it's a player-- 2-in-1 transport and DAC that has USB input, among other inputs.  And they play SACD's.
Whether DAC or new player the question is what makes them sound better than your modest unit?
Answer: Internal analog amplification circuit, power supply and filtering capacitors. Look under the hood.
I have a Marantz SA8005 SACD player and if you look for online pics of the chassis you will see what I mean.
The analog amplification circuitry gives the sound its drive, dynamics and energy as well as freedom from noise. The SA8005 does this quite well but is out of production.
The newer Maranttz SACD players do this well too.
I also have a Luxman D05 which uses an R core transformer power supply, the best IMHO. Lower noise and improved dynamics.
As others have mentioned The D03X is an excellent sounding player.
I prefer a one box solution. However there are some excellent DACs with robust power supplies. Look under the hood at online pics.  Avoid DACs or players with empty chassis.  
Hello,
The Ares is a nice DAC but I would stick with a chip based DAC. The R2R can sound a little warm or unresolved with your system. You might want to try the RME. The reason is you can set up the sound to your preferences. It will be slightly less musical than a Chord. But a good starting point into the DAC world. Plus it comes with a remote. If you feel this is for you they have a black version that steps it up a notch. I hope this helps. 
A dedicated CD transport and an external DAC is definitely the way to go.  I endorse the Audiolab 6000 CDT as a very good transport; there are lots of really excellent DACs.  You don't have to spend more than $2000-3000 total to have something approaching state-of-the-art CD reproduction (note that I said "approaching" - not "reaching").  I am sure you will be a lot happier with CD sound than you are now.
