At these prices, You might consider buying two of a model that seems most reliable.
One now, keep your eye out for another at a great price
I bought a Yamaha Receiver, CR-1040. Enough power for my needs, and less $ than the top of the line CR-2040. Turns out there is a relay in the CR-1040 that is potential trouble, and cannot be found separately.
So, I was going to run both my garage and shop speakers together. I do that at conservative volumes, or one or the other when louder, just to avoid pushing it hard, the problem I COULD HAVE KNOWN ABOUT if I had done better research. I also left more breathing space than I might have.
That problem does not exist in the CR-2040 evidently.
