ARC Ref 110 with KT 150 tubes

I am currently running a Ref 100 with KT 120 tubes, no probs, net gains on the old 6550s. But has anybody gone a stage further and used KT 150s? Any potential problems, you think?

Many thanks for advice.

Now that the SED 6550 winged C's are out of production, and apparently nothing else is as good, some have questioned if a KT88 can substitute. Imagine Gold Lions, Shuguang Treasures, Penta Labs or Psvanes...hmmmmmm

I'm in the market for a new preamp and the ARC REF 5SE is on my short list. I was concerned by some grumbling from owners who have received 6550we's as replacements and were not happy, so good news per your findings. Cheers, John
