Jim, welcome. It's good to read how you're enjoying your M50s, but I think that you'll find that the EP500 will add significantly to that enjoyment. Although not ideal, you can try it right now, before you get your receiver that has bass management. Use regular speaker wire from the Carver outputs to the high level inputs on the EP500 and set the low pass filter on the sub to 40Hz(you might also try 60). This won't work as well as with an HT receiver that can do a crossover, but at least you can begin to enjoy your EP500 immediately.
