Any Bryston 4B3 amp owners out there?

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.

I used to own a 4b3 for about a month or so, did not find that it was a good match for my Rethm Saadhana speakers. I found it too blend and too mechanical sounding and a little too colourful for my taste.  It was also pulling to the left a little which I found strange, and I noticed that when I switched from Kharmas to Rethm (it was pulling to the left with Rethm).  My only explanation was that I did not notice this with Kharma since they were 89db and Rethm are more sensitive at 103db. Anyways I switched to an Italian brand and my system sang. Just my two cents.

My system:
dedicated 20 amp line
Furman REF20i power conditioner
PS Audio P600 power conditioner for digital gear set to output AC sine at 110Hz
All Pangea power cords
Bryston 4B-SST² amp
Kimber 8TC speaker wires, double runs fluffed open with cotton insert
Magnepan 3.6 speakers
Bryston BP-26 preamp
Kimber KS1116 7 meter IC pre to amp
Audio Research Sp-15 preamp I use just for the tubed phono
Cardas Parsec IC SP-15 to BP-26
Kuzma Stabi/Stogi S TT with Dynavector 17D3 cartridge
Kuzma arm OEM IC
Sony SCD777ES
Kimber KS1016 IC from Sony to BP-26
Adcom DA700
Kimber KS1016 from Dac to BP-26
Various 5 disk changers/toslink
Behringer DEQ2496 from one changer to DAC via generic AES/EBU IC

I also own a Rega P5 TT with a Benz Glider to Bryston phono box, but it just sounds lean of late (My guess is the suspension is stiffened up?) and I never use it, just sits there. I LOVE the Kuzma!

That is some kind of system- elizabeth
Happy Listening!
