Sonic Frontiers Line 3 pcX upgrade

I don't own my Sonic Frontiers equipment any more but Chris was always a good guy to work with. Just google parts connection and his site will come up. The parts connnection can let you know what the current upgrade conists of now.
Nobody will pay return shipping for you. I think they figure it in to the upgrade price.

I own the SF line 2 and the SFCD-1, I had my Line 2 upgraded a few months ago, with the SE+ and volume chips upgrade, the background now is much quiet, and the sound stage is wider with more details and resolution, however, you can still recognised the SF signature.
I had the pre amp couriered to Chris at PCX and after the mod couriered back to me, PCX used UPS services, buyer pays rtn shipping, and I live on the other side of the globe where PCX is located.
You can contact PCX for the mod details and option you can choose.

I wonder if Chris is overcharging for the upgrade. Does he have any competitors?

The SE+ upgrade seems quite intriguing yet the price of it is rather off putting to me. I purchased my Line 3 new and have never had any additions or changes made to the piece. I am wondering if simply replacing all of the tubes would be a viable and economical approach to improved quietness and more authoritative bass. And, I do marvel that Chris doesn't appear to have any challengers in so far as offering the upgrades. Any comments from the members would be appreciated. Thanks!

I'm not sure about the specifics, but the hourly labor charge Chris charges doesn't seem unreasonable, and I would imagine that due Chris's business he would be able to get parts at favorable prices. That no one knows these products as well as him is a big plus. Unlike using other outside modders, I would think that his upgrades would retain their value much better than any competitors. I tend to prefer ss, but the tube SF Line 3 is one of my favorite components.
