I ended up doing R35-R36 by-pass & this point, it workes Extremelly well, I started with 1uf & worked up from there to finally settling on 4.7f generic PP film w/ a .022uf Vitamin Q over that, the results are super nice. Much better detail, smooth & sparkle without fatigue on top end, That Vitamin .022 bypass on the 4.75 film I would say is critical in what I ended up with. I have the Mundorf silvers in the C1 & C2 spot, the unit was the allready moded version DIYbiz.com has. I added extra set of RCA's so you can switch between stack output stage & the bypassed one. I also have socketed ops627's in the normal output stage. The bypass is prefered to me,also the gain reduction is not that much, I think I seen it measured somewhere as 1.4 v with bypass, so plenty for passive direct as I run. I didn't like this DAC @ 1st , but it has lots of potential & now runs with my best DAC & maybe better in some reguards. I highlly recommend the bypass with extra RCA's so you can see what you like best by A/B the 2. & forget about the supposed NO-NO on bypassing signal caps, in this case it is highlyy recommended.
