superphon revelation

To confirm the capacitor voltage requirements, before you get the replacement caps, measure the voltage across the existing caps. If it is less than ~ 14VDC, then a 16V rated cap would be ok. I wouldn't use an electrolytic cap above 90% of its rated voltage. It you use it above its rated voltage it could blow up. The closer you run to its rated voltage or if you run a little above its rating you will degrade it's life.

to Thistlehd i ment to ask you how did the bass sound . did it sound deeper

The bass is the real improvement in the superphon upgrade. I thought that the unit sounded quite good in stock form. It had great imaging, and a really nice midrange, but with the blackgates the midrange got even better and the bass was all there. I have compared this pre-amp to lots of other models, including an arc sp-8, and the new superphon (maybe slightly better) I love it. The power supply upgrades also help the bass, as well as the immediacy of the sound. I have three of these units, and they all run fine with the standard 16v blackgates. I have no idea why I still have three of them, but I think they are the biggest bargain of high fi.

thanks for the reply
