In recent weeks I have the chance to enjoy this set with a 5.0 amp Onkyo TX 508 after several necessary adjustments j finally have a very good sound I count recess complete my set with a subwoofer 300 JAMO although I already found quite low all on a CD of Black eyes peace finally to those who were reluctant to go for the best value of marchépar are planning against an amp with a bit of fishing and that makes the BI amplification option (as onkyo tx 508) you will gain in comfort listening.
