Hi Eweed, Actually, I also found a couple of reviews that compared the two, but again... they were reviews, written by paid reviewers. That being said, they present the M30s as a little bit more forward in there presentatoin too..
This actualy suits me better. I like my music a little more forward. Anyway, with respect the spousal approval? Well... the HL5s are much larger. So.... basicaly, they look like a big boring square boxes with dimensions of roughly 29" X 14" X 14". It's going to be pretty hard to camoflage those. In comparison the M30s are only 18" x 11" x 11". So, they're a little easier to hide. Hmmn? It may be time for round trip tickets for two to Hawaii. I bet that will get the speakers in the house.
