@cleeds - thanks for the suggestion and for checking out the arc website. I couldn’t find anything there either.
@erik_squires - thanks for that link! I’ve been googling but didn’t come across that particular thread. [EDITED - It seems to be conclusive on other ARC amps getting the 'SE' sticker and the KT150 seal of approval, but not my Ref 110. ]
I had a REF110 with KT120's. I called ARC and asked if I could run KT150's and was told not it could not. There never was a REF110SE. I had a D115-mkII before the REF110 and a REF150SE after (and now want a 160S). The REF150SE is definitely a better amp. Thicker, more colorful and fleshed out, plus more detail that lets you hear deeper into the music. Try to listen to one.
