First of all.. Let me say I have never heard the LeAmps. So take my opinion for what it is. But as a value - oriented consumer (read "cheap") I am very interested in trying them after reading the reviews.
It seems to me that Michael Barnes (Mr. Norh) knew in creating these amps at the $500 price point that they would be used by many to add power to their receivers/integrated amps. Therefore he put in a DC blocking capacitor to keep DC from reaching the speaker's tweeters and damaging them. This also made the sound "smoother", which probably is desirable with most receivers and lower-priced integrated amps being used as pre-amps.
Without the DC blocking capacitor (after mod) people say the sound really "opens up" and is more detailed. This seems to be the way to go if you are using better upstream components.
So, you can get the amps either way - sort of semi-custom made for your system.
