Well, I was the lucky winner of the last DAC-60 Danny had 
So, I have already changed out the ouput caps. My next mod is to change out the RCA coax for a BNC for true 75-ohm capability. Did any of you guys do this ever? I am looking at using one of the following chassis BNC connectors
1. Recessed BNC
2. Non-recessed BNC
And then hooking it up inside using this cable.
Thoughts? Comments?
Other easy mods I should tackle?
In theory, true 75 Ohm BNC *should* be better than RCA; however, how the thing will sound depends on so many things, including your digital cable's own impedance, circuit board/transmission line characteristics, and the quality of actual connectors.
I once modded my DAC with a nice 75-Ohm BNC jack, but I also had RCA so I could compare. I actually preferred the RCA input !

So I wouldn't spend too much effort into the BNC thing until you're done with more important mods.
BTW, that coax cable you link is way too large AWG and large for internal use, period. Most would use a good mini-coax cable internally..
