What's your experience, luck useing universal remotes for Integrated and Pre-amps? I mean the under $25 variety, not near or over $100 ones. From looking at the packaging description you can't tell if or what functions will work on your amp. My latest, is a Sony ES pre-amp TA-E1000ESD that I aquired from original owner with matching power amp. I had a RCA model RCRPS06GR remote with an Audio input button. This gives me On/Off, Mute, Volume functions. I can live with this, as a minimum. I've tried some other brands with less luck.
