Default Modding a GDA-700

Well here it is. I am only interested in modding the analog out stage, and the hoards of 10uf/35v caps. Can the BB2134 be used with improvement here? Also I am interested in removing the output coupling caps. I am using an active crossover, and I feel that the SQ would benifit from their removal.

Thanks
Ben

The OpAmps have Adcom P#ers on them. I would like to know what they are. I should check the rails, and see what kinda voltage there is on the OpAmps. The unit is about 10 years old. C514/515 are in the signal path I am thinking about bypassing these.
Anyone ever play with one of these. Is the GDA-600 the same except for the balanced outs?

Anyone ever mod one of these? The OpAmp would be compatable with the OPA134. The rails are 16.5+-vdc.
Thanks
Ben
