Best power amp ever. I used one for years and always got good tone, sold it when I took a break from playing, and when I came back into the fold I bought in to the "all power amps sound the same" concept. Its quite possible the Eden is not designed to be "flat", so I won't take on that debate, but as a bass amp compared to a QSC PLX 1602 (which has higher power ratings) ... there is no contest. The eden is deeper, fatter, smoother, fuller, clearer. The QSC is thinner, harsher, almost "fuzzy" in the mids, and runs out of steam far sooner. One channel into the same Aguilar GS410, I have to nearly max out the QSC to keep up with the band, it would occasionally go into clip limiting. The eden was half way up and I NEVER saw a clip light come on. I can only imagine what the 1500 watt Eden power amp would be like Both were run stereo with the same bass, same pre and compressor, same effects, same band, in the same room. It weighs twice as much and doesn't quite fit in a regular rack, but combined with a a good pre its the best bass amp I've ever used. Carry on.
