Ive always loved their Reference speakers......even of 10-15 years ago.

I had some 105.2 and 103.3 until 4 years ago.  I had some very expensive reference amps and cd player driving them.  Both were flat, uncolored and extremely revealing.  There was no glaring flaw to point at.  I sold them due to a pending move (I figured they could get ruined in the move)  but would still have them if I hadn't.  They compare favorably to reference dynamics now. I especially like the full range ability of the 105.2, and the superb bass definition.

The KEF Q70s are rated at 35hz on the bottom end.  They use the Uni-Q tweeter-midrange coaxial setup and a ported upper bass driver and a ported lower bass driver. The midrange and bass drivers are all 6 1/2 inch.

My 4B-ST goes to the Velodyne sub and it handles everything below 80 hz while the KEF's handle everything above 80 hz.

It works well for my system.

I have no direct experience with the Q70, but the older KEF that I had were rated very conservatively.  KEF used to rate mine 50-20khz +/- 2db.  The nominal response was actually 38hz-22khz +/- 3db- what is considered a "flat"  rating now.  They were strong to the low 30's and beyond audibility.  That was quite a feat for over 30 years ago.  They gave you performance more associated with 1990's "flat/extended range"  than 70's or 80's. I was surprised how much better they sounded with better electronics.  I heard them with a pioneer int amp- not bad.  But moving up to musical fidelity, Naim and others---they got better as a high end speaker should.

Kef and Bryston are a great match.

I wish I'd had a 3bst or 4bst.  I prefer Bryston to Naim, LINN and Musical Fidelity.

Current set up includes ...
JBL 1400 Project Array's with Bryston 7B's, BP 25 and BCD1
Purchased between 2008 - 2010
Cost $20,000

Even though your system isn't cheap in absolute terms, it's great bang for the buck in the context of high end audio.

What do you have now? A 2B?

Which brand of amps may I ask?
