I had 4b+'s driven by McCormack dna-1 monoblocks and then VTL 225 monoblocks and the sound was fantastic;
There was imaging,focus, and proper timbre (especially on strings).
This was my first pair of high end speakers and they were great; I think the 1b's are just smaller than the 4b+'s with not as many drivers.
The only negative I can think of was the black foam that wrapped the speaker made it a little harder to perform repair as I did have a driver smoke and had to replace it; service advice and the replacement from merlin was excellant.
