Bryston vs McCormack, any thoughts???

I'm looking for new choices in 2 channel electronics. These two companies are at the top of my list and I wanted to see if anyone has directly compared them. My speakers are Paradigm ref 100's V2. The two amps are the 4BSST vs DNA225
and preamps being the BP25 vs RLD-1. I've also thought about mixing the Bryston amp with the McCormack preamp since the RLD-1 has a great attenuation for volume. Any thoughts regarding these choices are appreciated. Thank you and have a great Christmas!!!
