Sonic Frontiers Line 2SE Upgrades

I want to know if anybody upgrade the SF Line 2SE Preamplifier. I have the Line 2SE but I read that some people replace and upgrade the capacitors (go to Audionote, Mundorf or VCaps oil capacitors) with excellent results.
Unfortunally I canĀ“t send the unit to Chris Johnson at Partsconnexion.
Please let me know your experience.

If you know how to do it Chris Johnson will sell you the parts you need for the SF Line2 SE Plus upgrade. It will cost you around $500 for the parts.
