Hi, I just bought my rotel 1095 (used) but haven't had a pre/pro to test it yet. However, when I turn it on with nothing attached to it, it will turn off by itself after about 10, 15 minutes. I think it is deffective somehow. If you are from the twin cities or st. cloud area and have a pre/pro, please please please let me bring my amp over to test it. I am still waiting for the outlaw 950 to come but I don't know when. that's why I can't test it yet here's my email i don't really know what to do with the amp. sigh... if you have any suggestions, please let me know.
