Thiel are generally (at least the ones I've heard) lean and hyper-detailed, definitely on the 'gray' side of things. ProAcs (2.5s, 2Ss, etc.) are generally fuller and warmer but less detailed, really on the 'cream' side of things. Thiel makes suberbly built and engineered speakers but they require careful component matching. The right ProAc can sound good with any number of tube and SS pcs.
Your pre-amp, by the way, is on the 'cream' side of things (kind of sounds like the color of it's front panel), and the Aragon is on the 'gray' side. Interesting match.
