Expect lot of problem with those types of cacades. Specialy if you want to do cablemodem service. With this P / V expect lot of problem with MER level. We usually get a 1.1 dB P / V on 5 to 7 amp. cascade on our return system. Thank GOD we are not using your type of amp. It is a shame that amplifier company do not test their amplifier more.
