Any Bryston 4B3 amp owners out there?

 I recently bought a used Bryston 4B3 and am very happy with it upgrading from the B100 everything is better.On a good LP the soundstage is incredible,great high end coming forward,3D sound and nice side soundstage.Wonderful bass.I didn't want to spend a lot of money for an amp when warranty out after 2-3 years to develop trouble.I've had enough of that and then the expense to repair and you get a 3 month warranty on the repair.My Bryston is warrantied till 2035.I would look for a used on on here.

Thanks Elizabeth. If I buy Bryston, I'd buy new from Audio Advisor and they are authorized. 
I'm glad that you're happy with your amp. Would you be willing to share what you're using it with, especially your speakers?

I find the Cubed and BSST2 amplifiers to sound significantly different. I strongly prefer the Cubed sound in direct comparisons, but I have met people who prefer the BSST2 sound instead also in direct comparisons.

nekoaudio,
It's my understanding that the biggest difference between the two happens at the input stage. The cubed input has dramatic refinements/changes and this is where most of the magic happens with respect to musicality. All of the hybrid amps I've seen have tubes at the input for that season.
I've been overwhelmed with opinions on two different threads. All but a few have been valuable and insightful. I've come to the conclusion that I'm going with Bryston. If I don't like it, I can return it. The Pass Labs, Simaudio, ML, etc will still show up used. Right now, I find no more pleasure in the buying/selling of equipment and the tweaking with cords/cables and the like. It's time to just enjoy the music and I hope the 4B3 is the missing link.
