I had a "red dot" unit with hiss problem. I had the unit for over 30 days and they gave me option of keeping until a fix was developed or returning for a refund. I returned for refund with no problems. I'm currently back to using my Yamaha receiver. Outlaw has been an OUTSTANDING company and I will not have any reservations about purchasing any of their products. I'm tempted to try the latest fixed version....nothing else on the market that can match the 950 for price.
