Run your axe and the F2B/SuperFilter stack thru a power amp, then call us back.
You've just run headfirst into the difference between instrument amps and professional gear. Remember, even good bass or guitar amps are generally built with 5-10% distortion, as our ears process this as 'warmth', and for most people, it is. Free yourself from these kinds of amps, and step off into pro gear (you're 2/3 of the way there) and you're dealing with distortion and all the other specs typical in that realm: Even the most el-cheapo, bingo-calling power amp is looking at distortion below 1%. Now for some people, this is 'sterile', but for others, you suddenly feel like the earmuffs have been taken off.
Couple what you have now with a 500 or 1000 watt a side QSC, a Crown, hell, even a CS800, where those low notes don't even raise an eyebrow on the amp, in other words, the classic 'great big amp only turned up to 2', and believe me, your Eden will become a nice paperweight. That really is the only way to truly do the Series (or any Alembic) justice, the way Ron intended so long ago. He's still right.
Once you have this rig assembled, you can also do what Jimmy does, another thing Ron envisioned: You can do an utterly minimalist rig: Straight out of the power supply into the power amp, where you REALLY, really are hearing it 'straight off the wellhead' to use a Pasadena-esque bit of vernacular (whereby I'm proving you can take the boy out of the oilfield trash, but you can't take the oilfield trash out of the boy. You non-Texans, you'll just have to wonder about this . . . ) And then with a power amp and a second Eden 410, you can run stereo, etc. All in hi-fi.
Consider yourself warned.
