Help me tune my Theta Gen Va DAC

Any word of advice is welcomed. I'm a newbee when it comes to tuning. One thing I was planning to do is to replace all caps on the power supply board with Black Gates. The PS board looks like this:

Do you think that it makes any sense at all ?

Do you think that I should use the same value caps ? And what type should I use (there are several different BGs) ?

Yes did. I have even found that I could use some lower voltage caps (6,7V instead of 16V) since the voltage was in the 3,7V-5V range, which would be about 4x cheaper, but decided to follow the original voltage values. In fact I in some cases I even exceed them, since original voltage was not available (470uF/50V instead of 470uF/16V for example).

Why? If Theta had a 16v caps in there the working voltage was probably no more than 8 volts, and BG makes a STD470/16,FK470/16 and a N470/16.

Sorry, I made a mistake here - I was quoting from memory. I replaced the 47uF/16V caps with 47uF/50V BG N caps, not the 470uf/16V ones. BG doesn't make N 47uF/16V and the N 47uF/50V is the closest match.

To make the long story short, I sold the Theta before I got the caps (they were backordered).

What did you replace it with?
