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.
