WOW!!! These things are great! Thanks Mike!
=Mike;245924]I swapped out the Sovtek 6550’s today and installed my NOS, matched SED Winged C 6550’s (from here: https://rover.ebay.com/rover/0/0/0?m...2F283069212072)
Much fleshier sound, slight increase in sweetness, just a touch of warmth. Vocals were the most improved. Vocals and instruments had a greater 3D presentation. I would consider the improvement quite significant.

Tried a NOS 6550 today. Added quite a bit of warmth. Not as sweet on top as the Winged-C, but certainly warmer.

Re: So has anyone replaced the 6550s in their Ref 10 with KT88s?
Mike...I may be incorrect however I kinda read Marty's post more along the lines of I would like to hear about user experience of this implementation before I consider such, rather than, I am in the process of making the swap to KT88's watch this space.

Re: So has anyone replaced the 6550s in their Ref 10 with KT88s?
This may have been mentioned elsewhere, but whatever 6650/KT88 power tube you like in your ARC Reference power supplies, you may not be hearing what they sound like if you're not using tube dampers on them. As I've improved my system setup, I began to notice a very slight haze/dryness using the SED Winged "C"s. It made me wonder too about my REF10 phono where I switched to Shuguang Treasure Zs.
For the last week, I've been using Herbie's Audio Lab high-temperature HAL-O IIIs on these tubes and really noticed a significant improvement in clarity and detail without any downsides of a more analytic presentation. They are made with titanium, not PTFE/Teflon or Sorbothane. Note, these tubes reach temperatures of 450 F so I wouldn't cheap-out with dampers of some other material, although PTFE ones will work.
I liked them enough, I'll be experimenting with the smaller size on the 6H30s instead of the ARC supplied dampers.
Note that Herbie's recommends the "50s size" for bulb-shaped KT88s, but that only allows them to be placed at the very top of the tube, not the middle. That seems to be just fine though. Have fun!

Re: So has anyone replaced the 6550s in their Ref 10 with KT88s?
So I tried the smaller Herbie's HALO-IIIs on the 4 ARC REF40 6H30 gain stage input tubes in place of the dampers that ARC supplies. Can't categorically say they're better. It would take more A/B listening and that's complicated since I'm using Center Stage Feet and it takes a while for those to settle when I move the preamp. I am going to leave the dampers in however. The HALO-IIIs on the big 6550/KT88s power supplies still sound like a good improvement to me. I don't think you can't go wrong with them. They seem to eliminate a slight haze that was bothering me.
These damping titanium rings are a tight fit and the pads don't seem to roll on the tubes like some others. Be patient and careful when you put them on!
