Mikey, yes i am using Ktema. I believe the brightness roots from the Nordost Frey Phono IC and not so much from the Ktemas. With that said, FS has the typical SF sound. I made the plunge yesterday and ordered Reference SC and three Ultra IC. One IC will be used as XLR phono cable. I had to buy new for IC in order to use the trade up program. I could not justify the cost to purchase three reference IC and i purchased the reference SC at certified pre-own price. Guess i will wait and see.
Mikey, i cannot imagine you passed up on purchasing the FS Ktemas?
