Just to add something to the discussion - after the cap shunting on the input, I changed the a-class biased LME49710 with a-class OPA627BP, because of the lack of warmth after the caps mod. The 627BP made the sound very pleasant to my (and others) ears, before the caps mod I preferred the 49710s. The amp runs hotter though, even with the side vents. Listening that way for several months now, I'm really pleased with the sound. Cheers, guys!
