ill trade you mine for the psp-2

I still think running through 2 preamps is a mistake. If you're going to keep the PSP-2 you should sell the V3 and get a Mytek.
The gain ranges I estimated were pretty close. I set up my computer to generate a steady tone, then from my DAC (Headamp Pico), I fed an unbalanced signal to my V3, and then SPDIF out to my PMD-661. I adjusted the signal to a specific level on the meter using the gain and the trim on the V3. Then I placed the PSP-2 between the DAC and V3 and measured the signal increase. I used the balanced outs on the PSP-2.Mic sens "-35": gain of +28 (ie., the meter increased from -40 dB to -12)Gain switches +6 and +12 add +6 dB and +12 dB respectively.Mic sens "-55": gain of +48 (the meter increased from -60 to -12)Gain switches +6 and +12 add +6 dB and +12 dB respectively.Mic sens "-70": gain of >+60 (the meter increased from -60 to "over"; I adjusted the trim on the V3 downwards by 4 dB, and it was right around 0, so I estimate that it adds about +65 dB)That's the best I can do with my equipment I have on hand.So the revised gain range for the PSP-2 is:+28 (Mic sens: "-35"; Gain "0")+34 (Mic sens: "-35"; Gain "+6")+40 (Mic sens: "-35"; Gain "+12")+48 (Mic sens: "-55"; Gain "0")+54 (Mic sens: "-55"; Gain "+6")+60 (Mic sens: "-55"; Gain "+12")+65 (Mic sens: "-70"; Gain "0")+71 (Mic sens: "-70"; Gain "+6")+77 (Mic sens: "-70"; Gain "+12")So there probably is a pretty big margin of error and it would be nice to get an actual number for the peak value instead of estimating it by eye. I would say +/- 5 dB. I tried feeding the signal to another computer but couldn't really get the digital in or line in to work.
