Sonic Frontiers Line 3 Mod by Parts Connection?

I have a Line 2 SE that was fully upgraded by Chris Johnson at PCX about two years ago. The full set of controls of the Line 2 SE were always great, but I had found the sound to be somewhat dry and uninvolving. The PCX mod solved those issues and I was pleased with the return on investment. The preamp was returned with newly made tubes (the old tubes and all other parts (very many) that were replaced were also returned)hat sounded decent, but I wondered what a good tube upgrade would offer.

Unfortunately, other preamps soon turned my head and I have yet to make the change. Maybe this winter. I can't say anything about the Line 3, but the numerous control options and excellent overall quality are very hard to match. I give a thumbs up to the PCX upgrade.

Sorry I can't directly answer your question about PCX upgrades but I would imagine Firebat may have a point when he says some people underestimated the break-in time for their upgrades... I also agree that Ckoffend makes a good point about the actual upgrade cost when one considers integrating a repair process at the same time.
As an extremely happy Line 3 owner which I bought new before SF went under AND with several "custom upgrades" [done at the factory as per my local S/F dealer's direction] I couldn't be happier with its overall performance and reliability. Servicing is still available at SF/Anthem though I doubt they do upgrades???
All I can tell you is that other components have come and gone over the years but for more than a decade my Line 3 is and will continue to be a staple in my system.
FWIW they are a steal on the current Audiogon market when they do pop up.
Good luck

They are great components. Only fault I've had issues with are with the many many relays. As is common with relays, they tend to get stuck after a time.

All out-of-warranty repair for Sonic Frontiers, Anthem and Assemblage products is handled by Chris Johnson(one of the original founders) and his crew at Parts Connexion. They also perform extensive upgrades and modifications to those brands and many more.

Chris / PCX does a great job of upgrading or servicing the SF gear. I can support the fact that the upgrades make a significant improvement to both power amps and pre's and - the SF gear was damn good to start with. I regret selling my LIne 3 that Chris upgraded for me and frankly it is still a reference piece that competes with the latest and greatest - I am in the hunt to get one back .......
