ARC D-115: What tubes and cables?


Hello all, I am seeking input on which tubes and cables will help in providing neutrality and extension in the highs for this amp. The tube complement is SED 6550 with 50% life in them and brand new Gold Lion and Sylvania NOS for the driver tubes. My dealer suggests KT88s slhould be next.
Any input would be appreciated!

No KT88s for D-115. SED 6550s are good, but must be matched. I liked RCA clear top 6FQ7s. Tubes from Audio Research will give you the most neutral sound, but they will cost you plenty.
