Does anyone know where i can get some XXK's for a real good price?? I am looking for (2) 4150-XXK's and (1) 2500-XXK. I heard that ARC is getting ready to release a new line of amps, maybe by the end of the year. Anyone else hear this. Also, if you could recommend other amp setups that would be similiar, and maybe for a cheaper price. Zed Audio might be another choice that i have found to be very reasonable. Thanks.
