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.

@orenstein,
" I realized you’ve already committed to a specific upgrade but I’ll add my 2 cents anyway. As important as a DAC may be, the transport is at least equally significant. The elimination of vibration and an accurate reading of the disc is where all the sound originates. If that part of the system is inferior, everything which follows wilOrnstein,


Words of true wisdom and experience. Too often I read well meaning advice in regard to digital audio. It generally over emphasizes the DAC and treats the transport as an afterthought (Any run of the mill CD player will do). Yes a CD player or cheap transport will function, but not at a high level.

Choosing a high quality, well designed/engineered transport will result in a significant improvement (Compared to any old CD player will do mindset) in CD playback sound quality. They deserve the same level of thought and consideration as the DAC. Both are important and should be viewed as a matched pairing. No one would saay I have an excellent cartridge so the turntable,  tone arm or phono stage don't matter as much. The entire front end chain matters.

If you spend an equal amount on your CD player to your vinyl rig you might find cd superior 
the Marantz/Ares combo may work great with CD being a small part of your listening, and if you move up, the Marantz is great for a second system, and you may be surprised what the Ares can do with a better transport...then after, the options become endless...
Done deal!
Ordered the R2R Denafrips Ares II
Couldn't have done it without you guys input.


Don't forget that you can still service your CD player.
(1) Clean the contacts with a contact cleaner.
(2) Check to see that it is level.
(3) Aftermarket Feet to assist with vibration control.
(4) Open up the unit and use dynamat - again for vibration control.
