A lot of the NOT truly balanced preamps still generate twice the gain at the XLR outputs. This may reduce the useful range of your volume control. Check the specs to see if the output of the Bryston doubles between the RCA and XLR outs. Then let your ears be your guide.
In my experience XLR's always sound as good as, and usually better than, RCA's. It might be imaginary but they give the sound a more airy, floaty quality.
