Anybody know exactly what was changed when H/K dropped the 630 and made the 635?
Off the top of my head, more advanced EzSetupEQ that does eq auto setup. Component upconversion of composite/svideo inputs. More advanced TI DSP is used in the 635. I think the only thing the 635 lacks from the 630 is analog bass management iirc.
So should I buy a 630 for a little cheaper or save the cash for a 635?
I think James' description of the differences between the two is pretty accurate. Choosing is a tough call. You can get steeply discounted AVR630's, including refurbed direct from Harman on e-bay. So it is tempting.
But when I decided to upgrade my H/K AVR520 recently, I went with the 635. To me, the EQ was worth shelling out extra for. Having never heard the 630, I can't compare, but I can tell you that the AVR 635 is just incredible. My H/K 520 is no slouch, but the 635 takes things to a whole other level. Sound is warm, rich, detailed, and powerful. I think a lot of that is due to the EQ.
I live in a NYC apartment, so my placement options for equipment are limited. So being able to implement H/K's advanced EQ to help manage my room was a godsend. Everything sounds great.
Basically, if you can afford it, I'd say go with the 635. You may also want to use the upconversion, but I don't currently run video through my receiver. It's nice to know I have the option though. If money is an issue, though, you would be just fine going with the 630 I am sure.
