I've used a few Rogue integrated amps with my Maggie 1.7s and was quite happy with all of them. The Sphinx is an especially good bargain and does a super job with Maggies. Rogue is also a great company to deal with. Currently, however, I'm using a Kinki Studio EX-M1 integrated amp with the 1.7s. Reasonable cost, substantial power/current, and excellent sonics. I will not be looking for a replacement amplifier in the near future. :^)
Here's a short review that I wrote for this combination....
