Hello! I have just got myself an Ampeg SVP-CL preamp. And I am in the market of a power amp. I have did much searching, and people complained about low output. Something about output ohms, sensitivity and balanced/unbalanced cable with the ampeg. If you know about a power amp that does fit the ampeg's speccs, please let me know. Ideally the power amp should push around 500w per side. If any of you got information about this, please write ! Thank you very much!
