I got my Epifani 310 UL cabinet yesterday. I was nearly floored when I took it out of the box. I knew this thing was supposed to be light and small, but this was way smaller and lighter than I had imagined. It is about the same size dimension wise, and lighter than my Ampeg 100 watt combo! Needless to say, I was blown away by the 310's physical nature. So, I hook it up to my Eden WP100 pre-amp/Eden WT1000 power amp set up. I'm hooking it up mono-bridged which delivers 1000 watts rms into the cab which takes 750 watts RMS. I love the headroom that the setup provides. I plug in my Spector and excitedely turn on my pre-amp and let it warm up for a second. Then I turn on the power amp and slowly bring the volume up to where it is a good bedroom sound level. Wow! I was amazed at how clean and tight the lows sounded (I tune my bass to C# standard). The low notes packed major punch and clarity. The mids were brilliant and full. The highs were crisp and clear. After playing for 30 minutes at this volume, I decide that it is time to crank this thing. I put on my earplugs and take it to a small gig level volume. Again, my first impression was: wow. This thing definitely seems to open up with more power and handles everything with ease. It sounded great no matter what I played on it (Slap, Finger, Tap). And good god does it look sexy! It fits PERFECT under my Rack case. I could not be happier with my 310. Gguitars.com was great and delivered it well packaged ($999 w/ free shipping). I highly recommend this cabinet to anybody that wants brilliant sound in an amazingly light/compact box. I can carry this thing around without the slightest bit of strain. Epifani hit it out of the park with this, IMO.
