I caught that in the setup diagram and simply ignored as it seemed only appropriate. I have it connected correctly but my question remains with regards to stereo separation on CD and MP3. Now I know the recordings or source have a lot to do with it and on most jazz cd's it is good but on some CD's and nearly all MP3's might as well use a Bose. Is it the recording or am I missing something?
Okay you have it connected correctly (in terms of Left channel of amp to left channel of speaker and right channel of amp to right channel of speaker) because you noticed the error in that diagram, but did you also double check to make sure all 4 pairs of wires connected to the speakers are consistent in terms of polarity, that is + to +, and - to - terminals.
Sorry for repeating this same question I asked in my last response but if you are suffering from poor stereo separation after you biamp, and you have the preamp to amps to speakers connected correctly in terms of left to left and right to right all the way through, then the only other prime suspect is that the polarities of the wires are reversed in one speaker. That is, you have + to + in one speaker and + to - in the other speaker.
If there is no mistake here neither, then may be one of the amp's (mostly the amp you added because you were fine before)output terminals are connected in reverse polarity internally (meaning the + terminal is actually - and vice versa). In that case you can find out easily by reversing the +/- at either one of the amp's terminals or the speaker's terminal but not both.
By the way, in the biamp/or biwire configuration if only the bass driver of one speaker's polarity is reversed you will get less bass due to the cancellation effect between the left and right speakers. If only the hi (or mid in some cases) range drivers are reversed in one of the speakers, you stereo imaging will be affected especially the phantom center channel. If you play a vocal CD, the voice will appear to float between left to right as opposed to coming from the center in a rock solid manner.
Other than that I cannot think of any other reasons that would degrade stereo separation/imaging in your system. Hopefully other members can offer more scenarios. Best of luck!
