Does any one have any sugestions on matching an amp for me. I am using NHT VS-2.4 speakers. They are rated at 8ohms and are rated for 30-180 watts. I have them crossed over at 65Hz to a pair of NHT Sub Twos. I am currently using DH Labs Cables and IC, with an Outlaw750 amp and Yamaha RXV-2095 as a pre/pro.
