Can only give you my amateurish opinion on a similar model - I got the FX5.1's a few weeks ago and had planned on the Yamaha 5630 to go with it. At the time Richer's were out of stock and offered me a Pioneer VSX-c550 which I believe is the next model up from the 301.
This was my first seperates system going from a Digitheatre DTS and I have to say, I was a bit disappointed. The c550 was a pretty weedy 30WPC, and I didn't like the look, display or notice a significant improvement in sound from the c550 over my Digitheatre (which is not to say it's shameful, the DTS is a pretty competant system).
I took the c550 back the following week and exchanged it for the 5630 which I am much happier with - better looking (more macho
), more powerful, better display and options, and IMO, a better sound than the VSX301.
The 301 can be had for about £150, yes, even picked up 2nd hand for about £100. I guess you know my opinion though
- for me the 5630 is a better option at £150.
