Hey all, I'll try to make the long story short:
Since finding a pair of JBL L50s at a garage sale when I was in high school, I've been a devoted fan. Had to sell them off a few years back, and I've been missing the heck out of them . . . so I went on craigslist and found a pair of ND310s. They look to be in very good shape, except that one of the center dust-covers on one of the woofers is slightly dented. Reviews that I could find seemed positive, so I took a chance and picked them up.
Got them home and hooked them up, and they sound . . . pretty good. But I didn't purchase huge JBLs to sound pretty good! These things should sound incredible! They seem just a bit muddy compared to the L50s, and I don't want to turn it up past about 5 (which is quite loud, but not block-busting) because even though I might listen to louder music on great speakers, that's about where it starts to get uncomfortable with these. It does not seem to be a bass problem, and does not sound different between the two, so I don't think this is related to the dented dust-cover.
I'm not all that well-versed in all of the technical aspects of audio, but I guess I'd say I'm a back-seat audiophile. I know good sound when I hear it, and I'm itching to get that incredible clarity I had with the L50s.
So. My first questions are to make sure that the system I'm running has what it takes to make these things sing. I'm using the same receiver and cables that I used with my L50s, so I know it's not a problem of quality in that department, but since these ND310s are designed to draw a lot more power, I'm wondering if perhaps my receiver is not up to the job. I'm running an old Sony STR-D1015, which is rated to 220W. It's not only at high volumes that they sound a little muddy, but I guess that's where my knowledge breaks down . . . Is anyone familiar enough with these speakers to know why they might not be sounding as good as the older L50s on this setup?
(I did play around with all of the equalizer settings quite a bit, but couldn't find a solution that way.)
Thanks in advance for your help!
