The SED 6550 had a very soft and rich midrange, almost mid hall sounding, not clinical sounding though. It made voices just a little too soft to let singers with an etched voice like Diana Krall sound natural in my system.
The SED KT88s much more dynamic and open sounding, yet still possessed a textured midrange. If you have a bright amp that is bothering you, you might like the SED 6550, if you want to open things up and be more front row center sounding, the KT88s will probably prove to be the best choice. The KT88 for me was the much better of the two choices in tubeds.
