Confused!

Slowly piecing together a respectable yet reasonably (for me) priced system. Right now, it's about the speakers. Was looking for a budget yet legit bookshelf, and landed on the Polk Rti-a3's and Elac Debut B6's. 

The Polks have a great clean sound, more than enough low end, and sizzle on the top. In fact, too much sizzle. I like things crisp, but not burnt. Where's the midrange?

Enter the Elacs. Andrew Jones, rave reviews, should be a sure thing. Great low end, fantastic middle, but missing some crispy goodness. After the Polks, sounds like someone threw a wet blanket over them. A day with them on their own though, I'm beginning to like them more. A lot more. Although, still finding that I'm twisting the evil treble knob that I shouldn't have (new amp day comes later) clockwise.

Finally, a question. Is there a more Polk-like B6, or a more B6-like Polk out there for less than $700? Should I stick with the Elacs and fiddle with placement? They will be forced to be close to a wall, about 1 foot give or take. I'm about ready to return the Polks, there's just not enough in the middle to handle riffage.

Room is about 12 x 13. Front end is a 10+ year old Yamaha HTR-5560 run in stereo mode and an Onkyo C-7030 CD player. No 'table in my future, I sunk my early retirement funds into CDs starting 30 years ago, can't comprehend investing in vinyl. Music tastes are mostly rock, punk, indie rock, blues, metal and its several subgenres, and a good sprinkle of jazz and polka. Speakers will be on stands.

Help!
