I think that question was for me. Yes, I've had the Exposure 2010s2, the NAD 375BEE, and the Rogue Sphinx.
I thought the Exposure was a very nice amp - refined sound, clear, musical. However, I had it paired with the KEF LS50s, and it didn't quite have the power to drive them. I later came to realize that I didn't like the KEFs, but I had already sold the Exposure.
The Sphinx really didn't work out well for me. I thought the initial sound was somewhat artificial, and I had problems with hum issues. It didn't stay very long, so I don't know how it would have sounded after the tubes burned in a bit.
Frankly, the NAD was the most enjoyable of the three. I know that NAD sometimes gets a bad rap, but the 375BEE was really a good amp. It has a metal bridge between the pre out and the power in. When I replaced that with a good set of ICs, the sound took a huge jump (it was already pretty good). It has tremendous control of the bass, and a very open, non-fatiguing presentation. I think it's overlooked due to prejudices against NAD and the fact that most people demo it without replacing the metal jumpers.
Just my 2 cents. YMMV.
Best, Scott
