So basically after trying a 1001RB-II with my bass through a Neo410 I feel like I'm sold on this amp. But I have some questions about it. I already have 2 GK Neo410's so it will be powering a nice wall of speakers. So my first question is, do you think that a 1001 is enough or should I jump up to the 2001? Next when I purchased one of the 410's it was a floor model and I didn't realize till I purchased my 2nd one that it is supposed to come with the GK bi-amp cable which I would like to use. Now are these wired like a normal bridged style Spekon with all four conductors being used or should I contact GK to get a replacement? While using the the bi-amp of the GK amps what is the best position of the knob on the back of the cabs? And an easy one.... Any want to trade their GK for a Sunn 1200S?
