We have a client with the Wilson Alexia using the T+A PA 3100HV which is one of the worlds best integrated amplifiers and he loves his amplifier.
The T+A PA 3100 HV is basically the company's $19k power amp and a paired down version of the T+A $18k preamp in one box.
The amp is a 300 watt beast and can drive any load, it is warm, punchy, very three dimensional and has an amazing feature set:
Amp can be upgraded with an external power supply
Amp can have a fanatastic phono board added
Amp has a analog parametric equilizer.
The T+A PA 3100 HV uses high voltage rails to run its transistors like a tube amplfier this creates a very full bodied and liquid sound yet the amp runs warm and not super hot.

In this review the T+A PA 3100 was compared to a $50k Dagastino Momentum integrated:
