My recommendation:
Entry level receiver: entry level BS
Mid level receiver (35+k): entry level FS or BS, mid level BS
Power amps or High end receivers: Mid level floorstanders
The higher model receiver you get, the better. That Jamo is a higher model FS with big side woofers.
In male lingo: picking a receiver is like chosing an engine for your custom built car. You can use a Kia Picanto engine on a Ford Expedition body, the car will still run somehow, but not to its optimal performance.
If you just want to hear just any sort of sound from it, go ahead with the 461. But if you want some serious HT slam (or gaming) or gripping, pissonurpants inducing action/horror movies. go for the high mid models or power amps (turbocharger!), they wont dissapoint.
avr+speaker combinations also change when you jump from entry level-mid level-high end avr's.
I agree, I have used 5 entry level and 3 mid level AVR's from different brands in the past years , then power amps, and the leap from entry to mid levels makes the difference. All the more w/ power amps.
I find the mid levels to be uncompromised & good in both music & HT. There may have been some comments in this site on Yamaha being better at this... Onkyo better at this... but that distinction is not applicable when it comes to the higher mid models. They all excell in both areas but the presentation is different for each. It just depends on w/c presentation you prefer.
