I believe my yamaha cd 755 puts out 2.0v I'm wanting to use the Behringer to bi-amp my polk audio rtia9's. I have a modded dynaco st70 pushing the mids and highs, but this speakers are powerhungry!! and have (3) 7 in woofers per speaker That are used for the sub frequencies. This are 90 db sensitive speakers, and the current kenwood integrated amp can't push them to sound tightly. do you think this amp will improve the punch and tightness I'm looking for. I'm new in the audio world and I rather ask questions to learn than to spend hundreds or thousands of dollars to try to figure things Out. Thanks.
