Hey all, happy owner of a 7125 amp and mostly happy owner of the OAW4 wireless transmitter/receiver system. It's connecting my HSU VTF 10 sub to my Denon AVR X3200W acting as preamp. The sound is great and I hear no latency, but every so often I get a really loud bass burp, if you will. Most times it's after I've shut the system off and went upstairs to bed. Wife does not like that! Anyone have an idea? Thanks!
