Changed title to get input on more possible options. So I just got a pair of awesome Carvin V210Ts. Originally, I had planned to run one at a time and just have the 2nd for the purpose of flexibility but I like these things so much that I'm thinking about just liquidating my current rig (F500 + AE410. Yes, they sound that good) and going with something 2 ohm stable so I can just run these however I want. The whole thing is still up in the air and it's not like the BX500 is particularly pricey so I might just hang onto everything, haha. Either way, I'd like to know how the F500 compares to the BX500, tonally. Your thoughts would be appreciated. -EDIT- Ruled out: Carvin BX500 - doesn't seem to have the tone I'm after. Genz-Benz ShuttleMax - big, expensive.
