Agree completely! I have the next model down (Expression ESL 13A's), and was REALLY looking forward to an in-depth review, comparing the new line to the prior Summit X and Montis models, vs. the non-hybrid CLX, focusing on overall bass/panel integration. Fortunately, JA answered that question indirectly with his measurements (flattest response he's ever measured). I would also have liked him to inquire why ML chose a 300 Hz crossover for all three of the top Masterpiece models, despite their different sized stat panels. He also should have listened with a tube pre and/or amp, to see if the ? perceived brightness was still there.
Personally, I'm thrilled with the Expressions, and hope future reviews of the new Masterpiece series will be more substantial in content.
