Bryston 4b3 or BHK 250- how woudl you compare them?

I have posted a couple of times as I am looking for new amplification to replace my Mcintosh MA7000 integrated but that I am running only as am amp with a Prima Luna premium pre-amp (this already was a big improvement).

The system sounds v good but I know I am missing some detail and I would like to get more depth to the sound stage in order to have a sense that I can "look into" the performance.

I have heard the 7B3 monoblocks and was very impressed- that said I was going fback and forth between these and Mcintosh 275 VI and I did find the Mcintosh more involving but just slightly less revealing.   You can see the write up I posted a while back.  Ultimately, if I were to chose I would go for the Macs- but alas both these and the Brystons are more than I'd like to spend.

So I started thinking about the Bryston 4B3 and BHK 250- they are at the same price point so I am curious if anyone can give me sense of the differences and their preferences, if any.

I would be using the Prima Luna as preamp and I am running Magico S1 Mk1- as i said I am hoping to get more depth and detail.  And I heard these speakers do that beautifully but I do not remember the setting and ancillaries- it was while back.   In the current set up I am almost there on detail and airiness (inserting the Prima Luna was a big upgrade) but the soundstage could use more depth in placing the performers in a 3 dimensional space separated from the speakers.  Lateral imaging is v good.

There is also Pass Labs 150.8 for sale and I am intrigued by that as well- power should be adequate but probably not much more than that as Magico's do tend require a good amount of power to be driven appropriately.

Your advice would be greatly appreciated- thanks as always!

Many thx for the great feedback.
ddfoe,  I think the pass labs would be great but I would be more at ease with the 250.8- exactly as your pairing,  I am a little concerned that the 150.8 might be slightly underpowered.  I do not listen particularly loudly by any means  but I try to match the music to its context and on some pieces I am a little worried the sound might feel a tad constrained.
What do you think?

As for the 4b3, i am hoping that that last ounce of involvement I felt  mc275 compared to 7b3 might be compensated by the tube front end.  dweller, do you  ind telling me what your set-up is in terms of preamp and speakers with what specs?

No views on BHK 250 pairing?

Go with an all tube amp. What is your budget?

sorry, i am traveling and i had not seen other posts- I'd love to try vitus but right now it is more than I would like to budget.

on classe, i own a cav150-a great and versatile amp- but it has a problem - I believe a circuit board needs to be replaced- and I am having a terrible time trying to get it fixed considering the changes at classe (no answer from customer service)- so I am a little reluctant to put money in a brand that I am not sure can address service needs.

As ofr some of the other names suggested they all tend to be above my budget of 5-7k (at the v max).

I thought the BHK might be a good compromise between tube and solid state- particularly since the preamp is tube.  I almost pulled the trigger on a pair of pima luna dialogue hp's with KT 150's- I assume these would capture the magic I heard with MC275's.  But being unsure I held back.
As I mentioned I am trying to add depth of soundstage and detail and get that sense that the performance hangs in its own space separate from the speakers.
