Well, if the player has ANY bass management settings it probably only has the choice of LARGE and SMALL speaker size settings. The crossover is in all likelihood fixed at some value such as 80Hz or 100Hz or 120Hz (or whatever). So, the only thing you can do is set the speaker size settings to those that are identical to what you are using with the AVR. In addition to the crossover being different, the slopes of the filters in the player and AVR may be different and that can definitely cause the two different connections, digital versus analog, to sound different.
But if you are setting your front speaker sizes to LARGE in both the player and AVR, the crossover will not be being applied to the front channels in either case so, provided you are comparing the two connections correctly, they shouldn't sound too different when conmparing 2-channel material. Realize though that when you listen to the digital connection, you are using the receiver to decode the material, and when you are listening to the multichannel analog connection, you are using the player to decode the material. So, it is possible (though doubtful) that you are hearing subtle differences between the two connections.

Well, ultimately you should use the method that sounds best to you. But in using the LARGE setting for your front channels you are not getting ANY of the benefits that are to be had by setting those channels to SMALL.
1.) Using the SMALL setting relieves the amplifiers from having to amplify the lowest frequencies, which are the hardest for an amplifier to amplify. Using a SMALL setting results in cleaner output over the range of frequencies that the amps ARE asked to amplify.
2.) Right now you are sending your front speakers, which are not
LARGE speakers, a full-range signal. Using a SMALL setting relieves the speakers from having to try to reproduce the lowest frequencies, which are the hardest for the speaker to cleanly reproduce. Using the SMALL setting relieves the speaker of having to try and reproduce those lowest frequencies which provides for cleaner output over the range of frequencies that the speaker IS being asked to reproduce.
3.) A SMALL setting sends the lower frequencies to a speaker and amp (the subwoofer) that are specifically designed to amplify and reproduce those lowest frequencies. A subwoofer's placement is also usually a bit more flexible so that its placement can (when possible) be optimized for reproduction of those lowest frequencies. Granted, you are sending a full-range front channel signal to the sub's high-level inputs and applying the sub's low-pass atop that so you ARE sending low frequencies from the front channels to the subwoofer. Still, you ARE sending those same frequencies to the speakers, as well, and you are adjusting the sub to the speaker's low-end output or roll-off in your room. So, depending upon how much room gain you might have, you are probably not reproducing as much of the low frequency info that is present in the front channels at the sub as you would be with an appropriate SMALL setting and a crossover being applied to the front channels. Just curious. About what low-pass setting do you end up using on the subwoofer with your current setup?
