Genera mods...

Hello all! I've been using my Genera phono preamp for over 2 years now and it's brought me a great deal of pleasure - many hundreds of LPs have coursed through it's little components and I've enjoyed every moment. Recently, I read through my copy of the notes that Graham sends out with the Genera kit and there's a couple of things he mentions that have piqued my interest and started me wondering if there's any mods I could carry out that would elevate it's performance even further...
Firstly, he writes that the electrolytic capacitors should be of at least 35V DC working value, but using capacitors of 63 to 160V will lead to improvements in clarity. Secondly, there's mention of using film bypass capacitors to effect a further boost to sound quality.
Has anyone tried this? Surely we'd be silly to ignore such a tempting carrot dangling right there! I'd be really interested in any thoughts on this, and as I'm no expert on electronics does anyone have suggestions as to makes/values for the capacitors that may be suitable for such a modification.
Regards, Tim.

Is going home with a note a good thing or a bad thing?

I modified my Genera with switchable input capacitors so I had 100pF, 220pf and both as options. Graham was very helpful.

I didn't get round to bypassing the input and output capacitors. If you leave the preamp alone and powered up, you'll be able to judge the impact of the TLC on the turntable better.
