Extremely important. More so than the brand of receiver.
Any receiver that uses spring connectors for main amplifier channels

be avoided.
These connectors provide very small surface area, and consequently, high
resistance, with a high probability of deterioration of the connection by
formation of a semiconductor layer.

Thanks for the comments. The Yamaha is a thing of beauty, but I'm more
interested in sound quality, so I will try for the Denon.

Question, is there any way to improve the surface area connection of
spring connectors (I have an Onkyo receiver and some anonymous Jensen
speakers that I like a lot, but which have spring connectors)?

No, there isn't. The springs push down on the wires with thin blades.
Otherwise, the spring pressure would be insufficient.
I cannot emphasize enough that these connectors are severely compromised. In
"the old days", the unsophisticated comsumer would at best be capable of
removing the insulation from zipcord. He would have no knowledge or source
of mating plugs. Properly terminated connectors, soldered or crimped with
high pressure, attached to binding posts that can be snugly screwed down,
are today's acceptable standard.
