The fact that you recognized my handle, then...nothing less expected. Bravo
Thank you very much
My calculations are really simple. The LCD-2 is rated at 91dB/mW into 60 ohms based off their stated website specs. The Oppo amplifier is also rated to produce 91mW into 60 ohms. So, since the LCD-2 takes 1mW to produce an SPL of 91dB, if fed the rated 91mW from the Oppo amplifier into its 60 ohm impedance, the LCD-2 would produce (if able to do so) an SPL level of 91dB + 10*log(91mW) = 110.6dB.
Audeze claims a greater than 130dB-peak spl spec for these headphones, but i bet it makes these levels at very high unsavory distortion levels.
Checked with Oppo about the possibility of changing the ampl gain and they said ti was a no-go as it will involve a PCB change on their part.
Given a choice between the two, i would choose Modwright since he re-designs the PCBs versus applying lots of shielding and other questionable thing TUC doess. Googlinng TUC feeback is very negative.
If a problem occurs that's related to Dan Wrights modification, he will fix it for free. If its due to Oppo, Oppo will fix it but will return the mod and the player as separate parts.
