Ok, now that I've kinda decided I'll be getting a rack system to power my 8Ohm 410 cab I'm getting deals from shops and these two do seem rather tempting: Sansamp RBI QSC Powerlight PL 1.4 (used) or EBS-1 (used) EBS EP800 w/ SKB 4U RACK (used) I'd like your opinions on which of these would seem a more sensible option. I play mainly heavy metal. Also, any thoughts on the QSC PL series? I've never heard them mentioned in the bass playing community, and new they seem to be a bit pricey. However, their power ratings (1400W @ 8 / 1000W @ 4 bridged) and weight of 18lbs / 8.2kg are tempting. Thoughts?
