Audible Illusions M3A update
No, do not under any circumstances send it back. They have a track record of taking months longer than expected to do upgrade work. I personally had this experience and it was agonizing. Ultimately Art felt bad about this and sold me a new one at ... 
Analogue or Digital sound level meter?
I have used both and find the digital one much easier to use. Also, the test results are fascinating. 
Tired of My Thiel's!!! UPGRADE TIME???
Make sure your 2.3's are broken in thoroughly and try Cardas cable. I ended up migrating to Proac and Spendor speakers, which are more naturally musical, but sometimes miss that honestly and authority of the Thiels.

Cables for Proac Response 2.5
I find that Audio Tekne is a magical combination for my Proac 2.5, but it is expensive. HT Pro-9 is quite good, perhaps a tad mechanical compared to the fluid Audio Tekne. 
Vandy and Thiel are severely different. Thiels are extremely linear and accurate and require lots of very clean power and a very clean source to sound good, or even listenable. Given your current electronics, I would not commit to Thiels without f...
