What DAC upgrade made you say “DAMN, that sounds SO MUCH better than my last DAC”?

@ivan_nosnibor 
Isn’t the Burl solely a A-D dac for mastering purposes? Or does it convert both ways, that wasn’t clear to me. I use the RME-ADI-FS with the Teddy Pardo power supply connected by a Synergistic Research Atmosphere Reference USB cable and balanced SR Atmosphere Level 2 cables going into my Octave V70 Class A.
The RME is stunning to me and my Audrivana files.

Emm labs over Cary for me

My Line Magnetic Tube/SS selectable LM-32 DAC.

Two years ago going from the entry Naim streamer to the dCS Bartok I traded fun for accuracy.  It left me scratching my head and holding my empty wallet, knowing I was hearing more of the recording, but it wasn't really that enthralling. After nine months with the Bartok I bought a used dCS Vivaldi stack.  I was pretty happy as it was more in all the good ways better than the Bartok (however, clearly the family sound), but I was holding my empty wallet again, thinking "I was expecting more".  It was still not the sound I envisioned. I bought that Vivaldi stack used and once I got it running I listened for a few weeks, then dug out the manuals and started through the settings. I realized that a software setting was set in which the clock was turned on and wired correctly, but the clock was not engaged. I changed the setting and that was when I had my WOW moment.  I get it now. I have been relentless in my search for that "liveish" sound I believed digital could produce. I have it now and I am extremely happy. It just costs a lot of money right now to get "that sound".

+1@audiosaurusrex, that's a tough one. I also use the RME ADI2 Dac Fs with Teddy Pardo PS. It was my this is what I'm looking for moment. I tried a few dacs ranging from 1k to 5k and this has been the best. Audio mirror, SW1X Dac, Aurender, Chord TT2, too name a few. The RME for about 1100$ beats them all in my system. Teddy Pardo PS about 400$ if I remember. Using a Kimber Kables D60 digital coax between streamer and Dac.
