Happy Thanksgiving Lalit! I just upgraded my DAC so will need to sell some components before circling back to upgrading my aR units and may attempt to DIY the Furutech sockets upgrade on one unit.
Re FI28 vs FI50. I only have one PC with FI50 which is attached via Neutrik on the other end to an aR unit so can't really A/B. Like you, I like the FI28 though the cheaper FI11 (CU) is pretty good to start with. FWIW, I may not go all the way with one particular type of plug as I believe, like tube matching, there is no plug that has no down side at all so I may throw in some good Oyaide plugs in the mix to keep the system more balanced.
