I'm just starting towards becoming an audiophile. I have a great ear for quality and clarity but am new to this hobby. I recently inherited some amazing audio equipment from a family member. The receiver is the integrated Denon PMA-2000R. Sounds wonderful, but only 2 channels. The speakers are the real jewels. I got 2 Energy A3+2's, and 1 Energy AC-300. Also got a great Boston subwoofer. Here's my problem: I really want to get a surround sound system. I know the speakers are a good start, but I need a 5.1 or 7.1 receiver and am not sure which one to get. Price is an issue and I don't want to spend too much $. For my surrounds I was thinking of getting Ascend Acoustics HTM-200's. Can anyone offer advice?
