I can't answer to the Caps used, but one other improvement that comes with the SE is an improved power supply. It was taylored after thye same power supply used in the LS-27 which to my understanding prompted the Ref 5-SE as it brought the LS 27 very close in performance to the Ref 5 Non SE. Again that based on what I have been told and not read anywhere.
Audio Research LS17 mod
In process of purchasing a ARC LS17. ARC now makes an LS17SE version which incorporate some new Teflon Caps, some other minor mods I guess to the circuit, and a new Face Plate with round buttons. I can not see the value in buying a new milled out face plate.
I don't see any talk here on mods to the LS17. Does anyone know what the new teflon caps are that ARC is installing. Or any suggestion on improving it's performance.
