I have owned an IO Signature with one power supply for over a year now and have about 600 hours on this setup. I am running 62db gain with a Benz LP and 1K ohms. I know that after about 30 minutes the IO Sig sounds better then cold, or this could be the accumulative effect of 46 tubes coming to life with the amps and preamp. I have not tried tube rolling and agree with Rushton about the stock Sovtek's having a magical appeal with the IO Signature.

I would be interested in trying the second power supply also. We are in the process of moving into a new build home and I will evaluate the space in the new listening room.

Rushton, I see you went back to the stock tubes. How was the sound of the other tubes in the system?

Audioquest4life, I will sometime try the vintage tube route again. I've heard good outomes from too many people to not at least give this another try. I just have not had the time to do so. In my sitution, I started with Telefunken 12AX7s in the second and third gain stages, then moved to change out the other tubes in the audio section. At the end of the process, the sound lacked the resolution and image specificity that we prized, and we lost the ability to resolve complex instrumental lines in complex music. Simple music (e.g., singer/song writer) sounded lovely, but the system no longer resolved orchestral music with the ease to which we'd been accustomed. As I say, we need to try the experiment again and spend more time identifying which tubes are doing what to the sound.
