Perhaps. I won't tell you receivers can't sound different. Like I have said a number of times, some receivers have been shown to sound so similar people could not tell them apart in blind listening tests.
You can read up on this and form your own conclusions.
As I said, the room correction feature on receivers can obviously make a difference. Bass/treble setting can make a difference. Any compression setting that was turned on can make a difference. Any processing option other than simply decoding the digital audio can make a difference. Differences in power, if one or both receivers ever went into clipping can make a difference. Whether the speakers are set to small or large can make a difference. Where the crossover was set can make a difference. And note that receiver's crossovers don't have to behave the same way even with the same setting. The channel trims for each channel can make a difference.
After eliminating every one of the factors, and any I forgot, and matching the receivers so they played at identical SPL levels (at each speaker,) a listening test in a store might have some validity.
I am not being difficult. I am trying to point out very real potential differences which I think could bias any attempt to do a listening test in a store.
Which is why some suggested a longer term test at home, providing you don't exceed the time alloted by your return policy.
Or, if you agreed with the evidence that receivers sound a lot alike when all factors are made as equal as possible, you could make your buying decision based on factors other than the elusive factor of audio quality. I realize that sentence is unreadable now that I re-read it. I mean to say, you can decide to ignore audio quality when buying receivers, after considering the evidence available. To make myself clear, I am not insisting you accept this. Just saying it can simplify buying.
Many people come to this forum and post stories about returning a receiver they did not like, and how they were wowed by another receiver they bought. But people also insist on some crazy ideas like how high fidelity power cords improved their sound. Only you can decide what you think is fact, and what you think is BS
