No, I love the 520C but just purely curious what the SM55s sound like as a center. I've had them for years and never tried them this way.
Easy enough to experiment, but reading some of your comments I'm sensing all kinds of bias so try to keep that in check. It's easy for it to "sound better" when you already have it in your head that it might just based on woofer size. I think you're well into expectation and sighted bias territory here before even hooking it up.
Now... some people get a little offended when you suggest their biases might be influencing them. I kinda get it, but it is absolutely
not an insult, dig or assumption there's something wrong with you. At least not coming from me. I know it's real, we all have it. No matter how much we think we don't or think we have it under control, we don't, and I've fallen for it myself. I just do my best to recognize it and take even my own experiences with a grain of salt. Simply being aware of how powerful it is helps temper expectations but you can never truly escape it unless you do the double blind thing and go through steps to eliminate any other possible influences.
That applies to you, me... everyone. Our senses all work together to create an image in our minds and preconceptions or sight can influence taste, sound, smell and vice versa. A lot of science revolves solely around controlling biases. I looked up and did some reading about it. I thought I knew what it was, but there's more to it than I realized and it's kinda fascinating really. It can be like taking a pill that alters your senses and you have no control over it. In fact it works exactly like that with the placebo effect!
