Ey up!
I have the 5As and I chose mine (yes, ok some time ago!) after reading a shootout of a lot of monitors where models of various prices were mixed and blind listened. The Tannoys beat some much more expensive models for general clarity and low colouration, qualities I seek in speakers.
Ok, they won't go loud and they won't go low but for my son's interests in jazz and classical music and in our tiny, 1200cu ft, "studio" they are fine.
Over the years I have found their bass response to be "honest". Most of the time you don't notice it but then a tune will come on and the heft is definitely there, but just not at window rattling SPLs!
Last but not least. Tannoy have a reputation to uphold and they have been making speakers since before even I was born! It is also almost all they do unlike SOME mnfctrs that make every other electronic gimcrack you can imagine.
