Sound of SED Winged C KT88 vs. SED Winged C 6550's

Curious as to what if any sonic differences I could expect in comparing the SED KT88's vs. their SED 6550 counterparts. I've researched the forums quite a bit over the last month or so and even asked the question to Kevin Deals gatekeeper @ Upscale Audio... his response was that there was little to no sonic differences between the two.

My amp is a McIntosh MC275 MKV, currently using the stock McIntosh KT88's, which I've been told by Audiogon's Nsgarch, are SED KT88's.

Getting information out of Upscale Audio isn't as easy as it used to be.

There are some major differences between a KT88 and a 6550 and I have always heard a big difference.

I recommend you try Roger Modjeski at Ram Labs for tubes. It's a much better experience.

The Gold Lion KT88 reissue does not sound the same as the original Genalex KT88.

For that matter, none of the reissue tubes sound like the originals.
