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

Look for a PS Audio DirectStream DAC used (the latest firmware really opened it up in a way that fits your search). Definitely change to better used cables!! You should be able to do both with your budget. Look for older generations of Audioquest, Synergistic Research, etc. This alone will move you toward your goal noticeably!!
If you are looking into strict D/A conversion performance, it seems like there are quite a bit of new high performance and reasonably priced DACs, such as the brand new SMSL SU-9 Balanced USB DAC (US $439.99), which perform better than most R2R DACs and many of the DACs listed above. The SMSL SU-9 has a SINAD of 120 dB while, for example, the Auralic Vega G2 has a SINAD of 116 dB. You can later decide to color your output signal using whatever, DSP, preamp or amp you like.

if you don't know already, there is a 'it measures good so it is good' school of thought in equipment/dac evaluation, and then there is a 'listening/ itsounds good so it is good' school

you will need to decide which is more important... people here have strongly held convictions on a vs b...  
@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.
