I was thinking of possibly upgrading my trace ah3007(300watts) to the new trace 500watt head,i dont know what its called. Its only a 200watt jump so will that increase much noticable volume?What I have now is fine but I was just thinking ahead just so I have more space for volume if I need it. The two cabs I have are the trace 4x10 and they are both 8 ohm so Im talking about running the head at full power. Atm I have 150 watts going through both cabs so if I enhance my head to 500 ill get 250 through both. Is this possible upgrade worth it?
