I'm curious if anyone here has sent there WT-800 off to Eden for the "B" upgrade? If so, was it worth the $500 upgrade? I'm thinking of doing the upgrade, but I'm wondering if the added 40 watts a side is really noticeable. Eden mentiones that the rating is pretty conservative which leads me to believe that there may be a substantial power upgrade. I also like the idea of being able to plug a 4ohm cab into the bridged slot and getting all 1100 watts out of there. I never quite understood why you could only plug an 8 ohm cab into the 800 to get the maxed wattage. Anyway, the bottom line for me is deciding whether or not I want to do the upgrade, or sell the amp and opt for the WT-1250. Either way sounds good, but doing the upgrade saves quite a bit of money. If anyone has played both 800B and 1250, I'd be curious to hear what the power differences are and overall preferences between the two. Thanks!
