I had my Line 3 upgraded with the Audio Note Silver caps.
I also have a Phono 1 that was up-graded by the parts connexion to SE++
I was lucky to have a factory Line 3 SE unit at my house to compare with my unit both before and after.
I have always liked the sound of the Line 3, the factory line 3 is a step up to the stock unit...I noticed it mostly in the musicality of the mids, with a slightly better bottom end.
After receiving the unit back from Chris I immediately noted that the modded Line 3 was now better than the factory Line 3 SE...best way for me to describe this is "It does everything better"
I also replaced the volume chips, my Line 3 is an older production with the "REL or Solen" caps on the outside of the heat sinks, not the newer Wima rectangle Caps. When I first received the unit back there was an audible "measurable" hiss coming from the speakers (I recall it being 10db ??? louder than the factory SE model)
I contacted Chris and his reply was simple...send the unit back on his dime and also could I send the factory SE to compare. Received both units back witn no hiss but the original volume chip (Chris said the newer one increased the noise floor by 1 or 2 db).
After letting the unit "form and settle" for a few months I put the factory SE into the system...there is a difference, the modded SE is a better sounding unit.
My Line 3 has a problem with humidity where it will cut the volume from the listening level to 30 intermittantly ???. Have though about picking up another Line 3 to replace mine, if I did I would most certainly send it to Chris to have his up-grade done. (I also have Power 3's that will eventually be sent for an up-grade)
This has been my experience, hope it helps
