Rob - I have good news for you and the other Turbomodded P-3A owners:
Just prior to THE Show in Las Vegas, I completed the mods on the Benchmark DAC, which required several iterations. From the learnings on the Benchmark, I went back to the P-3A and made some similar improvements to it:
1) Output resistors - Caddock
2) replace most of the regulators
3) Add more HF decoupling to op-amps and DAC chip
The effect of these changes is no less than amazing. It definitely raises the bar for this DAC. Puts it on another level entirely. The improvements are:
1) better dynamics
2) even less sibilance
3) clarity that I have never heard before in ANY DAC
I have not decided a final pricing on this upgrade mod, but it will be in the $200 range. I'm also a bit backed-up right now, but I will let everyone know on my forum adn the manufacturers forum when I have the time to do all of the upgrades.
