    WOW!!! These things are great! Thanks Mike!

    =Mike;245924]I swapped out the Sovtek 6550ís today and installed my NOS, matched SED Winged C 6550ís (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.

    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.
