I recently traded Tom Geroy my Eden WT400 for his Euphonic Audio iAMP 350 to use as my "big rig" with a fine, carved bass on which I have installed a Realist. I have both the EA v208 and V110 cabinets. I've only had it a week now and have played just one gig with the new amp, but I wanted to post my impressions. After a year of using the V208 with the Eden as the main rig, bringing the V110 along only when I needed a lot of volume or wanted to place a second speaker on the other side of the stage, I've found that the V110 sounds better with the iAMP350 as the main setup--it is louder and a bit richer in sound. When I hook up the V208 in addition, this sucker is LOUD. Friday night I played a straight ahead jazz gig with a guitar trio, tenor and female vocalist at a local bar restaurant. I used my carved bass, and the Realist plugged directly into the iAMP and the V110. I got a lot of compliments from people who were there, including a couple of bass players who came up and introduced themselves and said the bass sounded very natural. However, to get a sound that I liked, I used the iAMP in "flat" mode and had to turn the bass knob fully to the left. With this setting, the instrument sounded percussive and woody. With the bass knob set flat, it was all "woomph." I have yet to put the Golden Trinity mic back on and experiment more with it combined with the Realist thru my RavenLabs PMB-1. Maybe this week, I'll have time to do that. It is sure is cool though to just be able to plug directly into the amp and not have to fool a preamp, power supply, mic positioning, and all of the other stuff you have to futz with when you're running the pickup and mic combination. BTW, I find the sound of the iAMP 350 much more natural and HiFi than the Eden, and as a result, much better sounding for acoustic bass. This setup, when bungee corded to a luggage rack, is easy enough to move around and sufficiently better sounding that I'm going to put my GK MB150 away for a while and let the EA gear be my amp for all occasions.
