This is a tough one and Good Luck to you in advance.
I have not heard the Spendor 9.2. I have listen to (in detail) to a setup comprising of Spendor 7 with some expensive MBL gear. I really liked this demo and this speaker was one of my top 3-4 choices.
I then got a chance to listen to the ATC actives at AXPONA playing Daft Punk (Lose Yourself To Music). This combination was very musical and groovy. Unfortunately it was was out of my budget and I decided to not think about it. I will be honest and say - I did NOT get a chance to listen to those speakers at moderate volume. It was the fag end of the show and the music was loud - but super engaging.
If this speaker falls within your budget, try finding ATC owners on this and other forums and pose this question to them. BTW, the ATC and Spendors fall in completely different budgets.
