Hi, All. I'm going to be purchasing a new amp head and possibly preamp soon. I'm just looking for a quick comparison of these setups, as my local music stores don't have what I'm looking for. These would be used to power a Goliath III 410 (4 ohm). Eden WT-400 head (no preamp) Ampeg SVT-11p preamp SWR 800 head SWR SM-500 (no preamp) Or if you have any suggestions for setups that would sound better with my Goliath III, I'd be glad to hear them. TIA.
