Magneplanar Listening Comparison 1.7 vs. 3.7 Speakers

3.7 owners are going to love this discussion. ;) 

There are many justifications for audiophiles opting for the lesser speaker, and this is one of the most obtuse I have seen. :(

who advocated the smaller speakers and what reasons were obtuse?

I've always felt that the 3 series Maggies were the sweet spot in the line up. The smaller one's sound a bit bright to me. If your budget and room can handle them, I'd suggest going for the 3's.

In my experience, for a given manufacturer and model line, a bigger - and naturally more expensive model, will always sound better given enough room to breathe and fed by the appropriate amplifiers. You clearly have enough room so it's a no brainer that 3.7i is the better choice if cost is no object.

I've spent an hour listening at the dealer's with his music, and about 2 hours with a test CD I made up.  Not against a 1.7i, but against a 1.7.

The 3.7i does sound better to me, but even if the improvement is not due to visuals (the bigger speaker, known to cost nearly 3x as much _ought_ to sound better), I am not really hearing $4,000 worth of improvement.

In my room the difference may well be less, but there is no way to test them both in my room, or even to hear  the 3.7i at home without buying it outright.

That's why I'm interested in hearing other people's impressions of particular qualities to listen for next time I try them out.
