I hooked up the turbo duo to my surround sound system and it sounds great!! Absolutely no crackling or static and it's loud. The new premium opt amps used to modify audio devices really helps and also replacing those darn caps hepls too. You can really notice the differences. Let me know if any of you guys are interest in the opt amps mod or even if you need your bad caps replaced. If there are enough response I will consider taking orders.
