Upgrade DAC recommendation


My systems consist of:
McIntosh 601 Monoblocks 
McIntosh C47 Pre Amp
Martin Logan Renaissance 15A Speakers
 Node2 DAC

I’m  bypassing the DAC in my Node2 and using the DAC in my McIntosh C47 My sound is good but I think I’m missing something  and believe the sound can be tremendously better if I upgrade my Node 2 for a better DAC. I’m willing to spend up to $5k on a new DAC
 Based on my system components, can you suggest a Better DAC that will take my sound Up to new levels

 need lots of help

@aeschwartz -- thanks for the tip on Node 2i. I'm using it in my headphone setup with an external DAC. I had never paid attention to that particular setting but boy what a difference it made once I did. The sound is a little smoother and more liquid now.
I like Gustard A22 DAC’s sound, and how it looks. A22 uses two AK4499EQ latest ’n’ greatest chips from Akamai, buffered with balanced class A "discrete components circuit” outputs. Class A output on my opinion is much better than most design based with Op-Amp chips, and it does sound very close to tubes. Gustard A22 has “professional" look, very heavy for its size, enclosure is CNCed out of thick aluminum and deep anodized ( I have black version) , and internally uses high quality components. Power supplies for digital and analog parts are separated, and use different toroidal, shielded in cans transformers. The only negative note I have is a Display, which looks too simple, and also "Volume dB" setting could be larger. I would recommend anyone to check it out. 
Wow, thanks for all the input.

 Since I will not be able to audition any of
the awesome products people have listed here, and boy do they sound awesome,  I have decided to stick with a DAC that i considerably quite a bit at the beginning of this DAC purchase process.

 I’ve chosen the Lumin T2. Mainly because of it close proximity to the X1, the rave  people praise it, it’s cost, and it’s branding. The X1 is a little out of my price range. 

Since I have these cables now,
I will stay with Tributaries 8 Reference Cables. 
At some point, maybe my next upgrade
will be cables.
Thanks for all the helpful input 

Correction:
Since I love McIntosh Products so much
I canceled the purchase of the awesome Lumin T2. 

I Purchased and waiting to receive the new McIntosh C53. Even though at almost twice the price, I selected it mainly because of the new Next generation upgradeable DAC Module which gives me the ability to hopefully keep it for years to come and the 8 band equalizer 

Im trading on my McIntosh C47. Which is awesome  also
My new combo will be McIntosh 601’s, C53 and Martin Logan 15A’s

I’m good to go...... for now.  Lol
