You do not stand to gain a lot by upgrading your reciever, as long as you want it only for stereo applications. Your old reciver can still give a run for their money to many newer ones, when it comes to stereo perfrmance. Yes, if it has got any servicing done or its not as it was when you bought it, then you may consider upgrading. 120watts/channel at 8 ohms into two both channels from 20 Hz to 20 KHz at no more than 0.08 % THD is a very good spec. Stick to it save teh money and spend more on speakers/player.
