I read the glowing reviews on the new Anthem receivers, namely the MRX series like the 300, 500 and 700. Are they really that good and if so, can they be rated at the same level as the separates, like the integrated amplifiers? I am looking at the MRX 500, I would appreciate if any owners would share their views and experience with this particular model. How would you compare the Anthem MRX's against the Pioneer Elite, Sony ES, high-ends Yamaha and Denon? Many thanks.
