Question

I know you can insert, but I want the most efficient way. Also, if I use my tube preamps into the back end of the 2626, can I still use the front plug ins? Do they override?

Answer 1

I would go straight from the LA-610 into the back of the quantum at the insert return. this I believe would bypass the preamp on the quantum entirely.

I am not sure about the second question. I would bet the the insert points would control over the preamp.
