You may get a plethora of loudspeaker recommendations in reponse to your inquiry but in all honesty, you really should try and get to a hi-fi store somewhere in northern MI and listen. You may end up disappointed buying without listening first. We all have our own likes and preferences but in the end, all that matters is yours. I'm not sure how far up in MI you are but there is a store in Traverse City that sells Bowers & Wilkins speakers. They probably handle other brands as well (The Sound Room, 3275 S. Airport Rd, Traverse City 49684, 231-947-4710). B&W offers a wide range of bookshelf speakers. Their newest 600 series, which I recently auditioned, is superb. The 686 and 685 speakers are the two standmounts in this series and very reasonably priced. There's another store on the same road in Traverse City called "A Better Sound" (231-933-7225). They sell PSB loudspeakers, another excellent brand.
If you're in the UP and on the western side, there's a hi-fi store Marinette, WI called The Sound Seller, 2808 Cahill Rd, Marinette, WI 54143, 715-735-9002. They too sell PSB loudspeakers.
Another great brand is NHT. There's a store in Marquette, WI called Sound Surroundings, 517 Spruce St, Marquette 49855, 906-226-2828.
NHT are also sold at a store in Cheboygan, MI. They are Audio Video Solutions, 9916 N. Straits Hwy, Cheboygan 49721, no phone given.
So you have some choices if you can take a drive to these areas. But to recap, NHT, PSB, B&W, KEF, and Proac are great brands. CHeck out their websites. Good luck.
