10 Awg power cable to Bryston BIT-15 (Torus) power conditioner for less than 250$

I’m looking to put a better power cord to my 15 amp Bryston BIT-15 power condioner to the wall.

I would like to get the best sound quality I can over the stock cord. I was looking at a PS Audio or a Synergistic research (both used) in the $200 to $250 range. I was also looking at the different Synerfistic Research outlets and may upgrade my outlet at the same time.

Feel free to offer up anecdotes of your personal experiences with upgraded power cords and outlets in conjunction with your power conditioner of choice. I have been happy with the BIT-15 by the way. Bryston doesn’t get to mystical about using non-standard power cords when I asked on their forum so I’m asking here. I asked a question a while back concerning burn in with a new power conditioner. The responses came back dubious that the sound from the power conditioner would change much over time. I’m not convinced though and could swear that something settled in after I added the power conditioner. Similar to new interconnects that sound thin and unengaging, after some time in my system I think things are becoming better in a variety of ways. My inclination is that with some further tweaking it will become better still.
