Mods for Sophia Electric EL34?

Does anyone done, beside the cap changes the manuafacturer offers; know of any other circuit mods or favorite tube combinations used in this amp? Are there any owners of the amp? If so, what speakers are you using it on?

I made a change to 6u8 NOS Siemens input tubes [from the stock chinese units]...WOW! What a major difference in the sonics! I stumbled onto this via ebay.

Change the main power supply capacitors to blackgate 100uf/500V would upgrade the amplifier to another league if you have funds to do it.

Look into Sophia Electric's more expensive amplifier would be the next step.
