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.

You can't find real new old stock 6550s anymore. There may be a precious few here or there but the cost will be comensurately high. I don't know why you guys don't like the KT-88. It is a very good tube and the current production Gold Lions produce beautiful music in the systems I have used them in.
If you insist on 6550 output tubes they will also have to be Russian. I don't care for the 6550 sound so I can't suggest one over another. I think I have an amp that has EH6550s in it. It is in storage so I can't say for sure. I didn't like them that much I remember.
The drivers are another story good NOS should be "findable". Has an yone thought about using the KT-120s in an older ARC?
Yes!-Sorry for not being specific on the issue- The RS wires was one of those things that simply clicked with my system, and I was really surprised by this. And NO,they do not work well with the D-115. (It is a Mk 2 Hifi Geek).
Here is my System:
Modded Sony DVP 7000
Audio Research D-115 Mk2
Proac Studio 200
Audio Magic Xcallibur interconnects/cables.
One interesting development: Last night in frustration I angled the speakers INWARDS quite a bit from the usual position and Imaging improved nicely! However, they still do not dissapear as when I was using the D-120 with the Rat Shack solid cores.
