Here is my question: if you have a older bi-amp system, which came with a bass contour device, however is RCA and you want to run all balanced components from a DAC into a ARC tube pre-amp, then into two power amplifiers, one tube for the mid-high and one SS for the bass; is it possible the Rives Audio Parc would not cut into the high pass and defeat, or add to the natural passive crossover? I would like to use it if it worked as the original bass contour without the old parts and RCA inputs and outputs. The three parametric EQ would be an advantage, if only this did not cut the out the higher frequencies to any extent. If it does have a high pass crossover, what is available the uses audiophile XLR for balanced analogue components?
