Any Love For Bryston Here?

I had a Bryston BP20 and traded up to a BP26 Love it!!! I have a pair of 4BST amps (each on individual 15 amp lines), driving two pair of Maagie 1.7s.  Love these amps.  I produce all the warmth I need by using tube buffers in my system.  For just the smallest amount of lost detail, my tube sound is warm and inviting - like sitting near a good fire.
I would love to move up to a pair of 4BSST2 amps. Do any of you with 4BSST or 4BSST2 models have them hooked up to a 15 amp service? (I am not able to change my services to 20 amp).
Sorry ’bout the slight derail.

I am just itching to hear the model T with the outboard active crossovers.
only saw one pair come up for sale used about a year ago.  Hoping someone will include them in a setup at upcoming NY Audio show.
personally, got a pair of 7b monoblocks and 20bp preamp.

I recently bought a pair of Bryston 28B3 cubed mono blocks under the assumption ( or hope) that they would be a better match for some new PMC MB2SE speakers --- as Bryston and PMC had a long partnership & I believe many of their speakers were voiced with these amps in mind - in any case -- they are supposed to be a great match from all the reading I've done. 

I previously had a pair of ML CLX -- with 2 Decent I subs --- and again matched the speakers with what research I could find for a good match -- Spectron Musician III Mk 2 -- class D amps -- bridged as mono blocks - endless power / high amperage delivery for the demanding low impedance on the ESL's and fantastic sounding with the CLX - enjoyed tremendously for about 6 years 

I was very happy with the Spectrons -- but you don't know what you don't know - so I wanted to compare Spectron class D (which often gets a bad rap) to a A/B amp with the PMC speakers -- and was convinced that I would keep whichever one I liked best. 

After almost a month of back and forth switching between amps -- (still at it) keeping all the cables and sources identical when switching back and fourth -- playing the same tunes over and over ---- I really don't know why I can't tell the difference -- let alone find a preference - they both have 26db gain -- so the volume between the two amps was as closely matched as I could discern ------ but I'm frustrated that I can't really pick a preference - and by the time I switch the inputs and speaker cables between the two amps -- I've lost some auditory memory -- making it real hard to find a preference (wish I could just A/B with the same song back and fourth - but difficult to do without introducing other variable like cables etc. ) -- they both sound great -- similar tone & I would be happy with either one -

I'm just confused because I've read so many amp comparisons where users state "night & day difference" --- That has not been my experience ------- they are both great amps --- but now I know that there is absolutely no audible difference between this Class D amp ( 6 years old ) and a Bryston 28B3 (brand new) -- to my ears ( YMMV ). ------- Although if anyone can suggest a tune or two that might better reveal an audible difference -- I'd love to check it out -- but I think I'll be fine parting with the Bryston amps -- after realizing that if I can't tell the difference -- then there's no sense throwing money at it in order to feel comfortable having a new piece of gear with a 20 year warranty (knowing that my Spectrons will likely need work in the next 20 years)

@bjg I have a Piaget Dancer (about $15k) beautiful watch, and a Movado SE (about $1k) very nice also, both quartz movement. Doesn’t matter which one I wear, I’m always 5 minutes late for work. I thought the Piaget would get me there sooner..... 
I set them next to each other and watched them for hours, A/B comparison, nothing. I love Bryston and could sometimes tell the difference between it and a couple other amps I had. Where I could tell a big difference was listening to live and/or acoustic music, especially when listening to loud music with very quiet passages like Counting Crows’ “Round Here” or “Anna Begins” or electronic music like Dido or Sarah Fimm. 

I own a 4B-ST & 4B-SST2.... they sound different!  The ST is a bit more lively and dynamic, and the SST2 more refined & controlled.  The ST is the ideal amp for my old B&W 801series2's, whereas the SST is better on speakers that are a bit brighter.  I like them both for system matching.   On some speakers, I can see the argument that they might be too bright.  But the bottom octaves just go down forever!  Bass control and slam is the best.  I had my 22yr old ST reconditioned by Bryston a few years ago... One channel was having DC offset issues..... Best $600 I ever spent.  It's better than new now with modern capacitors!
