Well I did the upgrade from the standard version to the maxed out version with Dueland caps, etc. It's been running in for about 3 weeks now.
The DAC has been transformed, I'm very happy with the results. The character of the DAC didn't change it just got better in all of the parameters. I would equate it to a significant preamp or cartridge upgrade. The noise floor drops siginificantly, there is more depth to the presentation, more contrast (tonal and dynamics). It gells the performance better similar to a high end preamp or cartridge. The performance or musical expression is drawn out of the 1s and 0s making it sound very analogue and similar to my TT setup (DV XV1s, TW Acustic Raven, TW 10.5 arm, Tron Phono). Not one of my CDs sounds bright or has a fatigue factor. The detail isn't being drawn out and highlighted it blends into the body of each instrument, balanced. If you've listened to a really good TT setup you will know what I mean.
The DAC has pushed my system over a line. A much larger % of my CDs are just as good musically as my records, never thought that would happen. I've been doubling up on music that's important to me buying lots of CDs before they dissappear. Good time to buy!
This is an end game DAC for me that compliments the balance of my system. The standard version is also very good. To equate it in cartridge terms the stardard version is like a DV XX2MkII and the maxed out version like a DV XV1s. Both are very good and I could easily live with either but once you normalize to the upgraded version it would tough going back.
Thanks Vlad!
