Here is the way I see it. The Emotiva is a good amp for the money and a Great Value. The Parasound is a great amp for the money and a Good Value.
If your split on two amps with such a wide difference in price, that tells me the Parasound may be within your budget. So do yourself a favor and get it now. You'll avoid any buyers remorse because if you go for the cheaper one, you'll be asking "what if" every time you listen. Best to end the upgrade spiral as soon as you can.
