If you have a Proceed mono amp you have mono not stereo. You need 2 mono amps to give you stereo. You stated you have speakers connected to main amp. What model Proceed amp do you have ? I am very much an audiophile and would like to help. Looks like you have the start of a great system just needs some tweeking.:cool2::drink:
spitter, I do need help here. Let me preface this conversation by saying that there are only three reasons I carried this system over to my cabin was that #1: my old low end system is failing, #2: this system was free, #3: curiosity.
I do appreciate quality sound and I listen to music all the time. I like sitting down and listening to good music. But, I'm not an audiophile, I do not have a media room for this purpose at home or at my cabin, my friends and family are usually not interested in sitting down and listening to music outside of a casual social situation.
All of this is to say that as much as I'd like an awesome stereo system I do not have much reason to spending a lot of money to get this system up to top audiophile performance.
So, as to the amp: It is a Proceed HPA2 "dual monaural amplifier". I only found the one unit and only found one set of output cables to go to it. It was used in my cousin's media room/home theater. My quick research shows it to be between 12-19 years old. It looks new. I could swear I was getting stereo sound through it listening to Pink Floyd's Animals last night. It has "left" and "right" marked speaker outputs on the back. I'll look in the basement where I got it again to see if there is another one but I'm 99% sure there isn't one. And to be honest I'm not sure I would be willing to shoe horn another one of those monsters in my little cabin. It produces a lot of heat.
The pre-amp is an Audio Research LS16. It has tubes. It takes 45 seconds to start up. Its output cables are large 3 pin (?) deals that match up with the Proceed amp. There are no speaker outputs on the pre-amp.
If I can make this system work with what I have I'd probably do it. I might even be willing to put a couple of hundred bucks into. At normal and low casual listening volumes it is very clean and crisp to listen to so other than the space it takes up and the complicated start up there isn't a huge downside. And even with whatever flaws there are with how I have it set up, even my wife can notice a distinct quality improvement over the Bose bookshelf speakers driven by a 40 year old Toshiba 25 watt tuner/receiver.
I guess a big question is this: If I can't get this amp/pre-amp combo to work properly and in stereo there is no need for me to keep them and so what wattage basic receiver/amp combo would I need to purchase to drive these speakers and get reasonable sound quality?
Thanks for your help.
