That's what I got as well - it skips the cathode cap, and PS cap. Any change in gain, hum, noise, etc. should be simple enough to measure, which would confirm / deny all the other effects.
BTW, there has been a little bit more coming out on vibration effects within electrolytic caps, esp. in PS duty. The internal plates can actually move in response to strong AC signals, causing nonlinear modulation effects on the power rail. Bypassing all this would seem to be the way to go.
