Auditioned Brystons when I was using the JC-1s. The Parasounds proved to be the superior amps. If your looking for a VERY musical and still detailed SS amp. The Ayre V-1xe is better than both of them.
I prefer the Sim Audio and would point out the reason the gear sounds so good with Dynaudio etc. is that it doesn't bleach out the harmonics as a previous poster advised. My $0.02. If you want more tubelike harmonics you will need to throw in tubes in the chain. Sim gear is also fully balanced plus RCA's. PS I have had a Bryston 4Bsst and I use my Sim W5 and I7. I haven't used the Para gear.
No direct experience with either Sim or Bryston but I will say that after trying at least a dozen different amps (tube and ss) with my Duntech Princess (Dynaudio tweeter and woofers) I bought JC-1s a year ago and my search has ended. They offer detail and control without typical ss hardness or glare - highly musical.
