OMG!!!! I had a religious experience today. I finally got to make a road trip from Mt. Pleasant, TX to Dallas (actually Garland) to Larry Morgan Music. They are the closest hi-end bass store to me (two hour drive). The main cabs I wanted to hear were the Bergantinos. The first cabs I saw were an HT310 sitting on top of an HT212. I took my StingRay 5 along for the ride & they hooked up an Alembic F-1X to a QSC PLX1602 (just one channel--500W@4ohm--they seemed reluctant to bridge it for me--not sure why) to the 3x10. I fully believe that my tone search has found its holy grail. All my expectations were so totally blown away by this rig. I restrung my bass last week with some DR Low-Riders and they sounded pretty amazing already (compared to the Ernie Balls I had used before). But I had no idea that my bass could sound so good. I have always had questions about its midrange and have most of the time used a fair bit of cut on the treble control. Not with this rig. sMOOOth!!! Awesome bottom to top. Really solid, powerful, articulate low-end; punchy kick-in-the-gut mid-bass, and smooth, smooth, smooth all the rest of the way up. Any setting on my bass sounded musical and before I had only found about three settings that I thought were usable. I still can't believe the sound these speakers pumped out. I listened to the HT212s and maybe it was the demo room we were in (it was kind of long and narrow), they sounded really good, but just heavier down low without the mid-bass punch of the 3x10s. I think they would have sounded a lot better in a bigger room. The HT310s just stole my heart. I'm very probably ruined for anything else, but they didn't have an HT322 in stock so I haven't heard it yet. OK, enough of my blithering. What I would like to know is what you Bergie owners like to use as preamps in your rigs and why (as well as comparisons to other preamps you may have tried in the past). I am considering getting and bridging a QSC RMX1850HD for the power amp. Cool?
