I can say this after doing some small testing in a small room 14 x 14 with a 10 inc sub.
The bass from the Sony's was there. There was a lot less detail in the Sony, maybe the sony center was a bit more clear.
If you want detail then I would stick with HVL-1 in a small room.
I an large room 25 x 25 a SVS PB 2000 the center channel sounded boxy this was with a set of there towers and and two book shelf's.
The was a guy doing a tests between the Chane A.2 against the Seria 2's he chose the Chanes over them.
He said that the Seria 2 was a better speaker but it was not as good as the Chanes at higher volume.
The Chane A.2 looks to be hard to place because of there size. The WAF factor would be less i would think two. but for movies and the cost the Chane may be a better buy. I would venture to say the even there book shelf would be a better speaker than the Sony at 329.00 a pair not a bad price.
Interesting. Which center channel were you using? The Sony Core center seems to get mediocre reviews from users. If most of the detail (voices, etc.) was coming out of the center, a poor center might account for the impression that the Sonys have less detail.
If you're just playing stereo content through the bookshelves, do the Sonys seem to still have less detail than the HVL-1s?
Playing stereo content on my desktop computer, my Sonys are far and away more clear than my HVL-1s were. Absolutely no contest at all.
Maybe something really was wrong with my HVL-1s. I did buy them used off of Craigslist, after all. But I listened to the left and right channels independently and they both sounded identical to me, so what are the odds that the same thing went wrong with both speakers??
It doesn't come down to my room or positioning either, since the HVL-1s had the same problems with clarity and detail in 4 different rooms/locations that I've tried.
