This sounds like an excellent idea. The SR009 is comparatively very sensitive (feels louder) than my Omega 2mk1 at the same volume level and, as you mention, the O2mk1 sounds better at higher volume levels. I wonder then if having the O2mk1 plugged into the high bias and 009 plugged into the low bias would yield similar loudness (in the rare case where I listen with my wife or if were to use a realiser for movies playback through the phones).
Apart from the drop in gain (6dB?), any other drawbacks?
Anyhow, Justin, would that even be possible for me to consider (in place of the 2 pro bias stax plugs currently) at this stage of the build? Maybe two pro bias plugs but a different bias setting on each output? (In my case, I don't foresee using normal bias phones, or I'd simply look for a used T1 just for that).
yes, i can still do it. this is probably the last batch where i will be able to. too many combinations of jacks/colors/volume controls means i cant have someone else do that part of repetitive assembly without mistakes
Would have differing bias levels affect the performance at all? Or would it effect the same thing as having different gain on each socket?
