I recently purchased a pair of 1.7s (new). I play them in a wood paneled room (my office) with oxygen free (non-audiophile $.50/ft) speaker wire. Power is provided by a piece of junk (Old Yamaha AVR rated by the manufacturer at 85/channel into 8 ohms probably about 100 into 4 ohms). And I run them without resisters. They do not sound bright. I do not play loud, though and am planning to upgrade the power source (possibly with tubes).
Here is my advice. Make sure the speakers are angled so that the woofer is a little closer to you than the tweeter. Magnepan recommends that the tweeter be on the inside (speaker with serial number ending in ’1’ is the right speaker). I find this is best if you are able listen from near the ’sweet spot’ If you listen at higher volumes, by all means make sure you have enough power, and consider tubes as they tend to be ’warmer’.
