Parasound is fine. I own one. It has a great punch. Bryston is fine too. But if you're looking for a warm natural sound with the same punch, you won't do better than a McCormack DNA-1 for $800-900. You might do better with a Levinson, but it'll cost you. There's a used DNA-1 for sale right now for $850. Poke around in the forums and read the glowing comments. You won't find anything in this price range that compares.
