Ok, when i bought my Pioneer last year I was thrill to bits with the performance. However, for a while now I am a bit bored and realised that there are areas where there is alot of room for improvement especially in surround or stereo. Originally, I had a Yamaha 795a and the 5.1 performance good ambience, precise and all involving in surround sound. I now find the pioneer a bit flat, uninspiring and direct compared to yamaha in surround. And thats the main reason I still have the yamaha in the living room. However, the one area that the pioneer excels is in analog 6-channel mode. Currently, the yamaha 2400 is at £650 which is £70 less than Pioneer. I am seriously thinking about changing/ upgrading my receiver? On paper, the Yamaha has better features: audio delay , 8 channel multichanel external, video upconversion and 120w*7 and 2 subwoofer terminals. While the pioneer has usb 2.0 audio. Do you think its a wise move? before I have an audition.
