IME, the old SAE stuff is overrated. It has all the defects of that period.
It is much noisier than modern equipment.

My experience supports your statement. I had a 1980-ish vintage amp and
preamp that were noisy and very prone to failure (especially the amp).

On the other hand the QUAD 405 is rock-solid, totally dependable and
pretty much indestructible. If you can get one, the 405mkII is better as
it provides more current into difficult loads, but as I recall, the KEF
Concertos weren't that difficult to drive, so the 405 Mk1 should work fine.

Sadly every single time I've heard a Quad 405 they sounded utterly lifeless and
dull. No other amp of that era has acheived this. No idea why. Of course it
needn't have been the 405 at fault.
