Magnepan 1.7 i - Amp suggestions

If you like tubes - I am using the big Primaluna HP Dialogue Premium, which has 4 EL34s per channel. Sounds really sweet with my LRS.    Only ~80 wpc, but plenty of current.  I think the smaller Primaluna with 2 EL34s per channel would not be enough.  Also, now that they have introduced the new EVO series, I suspect the HP might be more available on the used market and in but at the top end of your price range.

I have Magnepan 0.7s. When buying I auditioned NAD 368 and Rogue Sphinx. The NAD had a bit more sibilance on vocals while the Sphinx sounded more natural. So I went with Sphinx and am very happy. BTW, ignore claims that any class of amp universally exhibits a common characteristic. I bought a Musical Fidelity class AB amp and found it brighter than a different class D amp on my particular speakers. There is no substitute for hearing the equipment yourself. You’re off to a great start with Maggies.

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....

Hi, I drive my 1.7i's with Conrad Johnson MF2275SE amps. Avoid Class-D, buy used, plenty on the market. A lot of people swear by Sanders Magtech, but any amp which doubles in power from 8ohm to 4ohm will do the job. Good luck.
