Hi, This my first post. I am a 67 year old man who is just getting into AV. Over the years I had some decent stereo systems. Now I have nothing. I have a very modest budget to put in a surround system in my small apartment. I have found speakers I like that will consume slightly less than 50% of my budget. These are older high end speakers. I need a receiver. Again I will likely buy used or at least refurbished. My question is how far behind the state of the art can I buy without having an instantly obsolete syste.? I am looking at a 5.1.2 system based on the speakers I have located. However I might want to add a second subwoofer later if needed.\ni have found an Integra DRX 2.1 at a very reasonable cost. Likewise a Marantz 5012, and several others at 7.2. So, what do members think of the two listed models and what other receivers can be recommended. The budget for this device is 400 dollars or less.\n\nif it helps the speakers are AR holographic M series speakers from the 1999s.\nthank you all.
