I have joined the SLI-80 ranks. I was able to grab a good deal on a used one and have been putting the hours on it this weekend. It has some of the F1 mods (Jensen caps and Kimber cable CD input) It came with Genalex KT88's and Electro Harmonix 6SN7's. I added Genalex 6922's and Philips 5R4GYS's to the mix. It is a wonderful addition to the 2 channel rig.
I am running it with my venerable Vandersteen 1B's (at least 25 years old!) and they have never sounded so good. I DL'd some new DSD128 files and it is remarkable.I feel like I am in the club at the 2nd row table.
