Had Three Different Speaker Thoughts; Now A Fourth


I currently have B&W 606 S2 bookshelves and I am thinking about doing something different, I haven't been overwhelmed by their build or performance. So I read and read and read some more and I think I have it narrowed down to three choices. Auditioning any of them is highly unlikely.

I've looked at the Tannoy Eaton, the Volti Razz and the Magnepan 1.7.

My listening room is 12x25 and there's not a lot of room for moving my LP (odd closet and a center of house chimney). 
I have a Parasound Halo6 Integragrated. 
Given the size of the room would the Razz be too much? This is my top choice.

The fourth option a friend mentioned and it has appeal is this... I also own a pair of Polk RTiA7 towers. They are a really nice cabinet with a nice build that house a 6.5 and two 7 inch drivers and a tweeter. He said I should think about replacing the drivers with Scan Speaks and upgrading the crossovers.

Thoughts?

I've been working to pay for these musings so forgive me for not responding sooner. @soix I'm looking for magic of course! I'm looking for imaging and soundstage, coherency, presence, smooth solid bass, dynamic and fun.  I live in the sticks and have never heard an electrostat or planar, never heard Tannoy and limited experience with horns.  I've gone batty trying to get my bookshelves and subs integrated, it finally sounds decent but not great. Not really any further ahead than when I was using the Polks which honestly punch above their weight. I think it's got a lot to do with timing and placement in my current set up. @erik_squires I've read up on the Fritz' in the past and I will revisit it for sure, just not convinced on the whole bookshelve / sub combo anymore. @avanti1960 I tend to agree with you after some sleep and thought. @jasonbourne That's the concensus. I can see it in the case of the Thors as @mozartfan has done but probably not with the Polks. @roxy54 I guess I did need to be a bit clearer! @kcpellethead  my house is a square within a square meaning my front wall opens into the dining room. I can place my right speaker where the wall would be without sidewall relections which allows me to put 8' between my bookshelves.

Given this I’d recommend saving a ton of hard-earned $$$ and try a pair of LSA-20 Signatures available here from the manufacturer for only $2299/pr. Read the reviews. They’ll be a huge improvement in every parameter over your monitors, and they have enough bass that you’ll likely not feel the need for a sub anymore. If in the unlikely event they don’t absolutely knock your socks off (but they will) you can return them, which is a really nice option especially when you live in the sticks. Best of luck.

Have your dealer set up the Maggies in your room and give them a few days to listen to a wide variety of your favorite music.

If you do not like them IN YOUR ROOM, buy something else.  However, be sure to critically look at your hardware as well.  You will hear whatever it adds or subtracts from the music with these speakers, so it may be time to change some of your components, or not!

Cheers, and happy listening, which is what it is all about!
I think given the financial commitment you are going to make, that a road trip is in order.  If you have never heard Maggies, you definitely need to hear them.

I say this because people often are drawn to them, or not.  In my case, I knew they were for me immediately.  You nay or may not have the same reaction, but the only way to know isin person.  As an aside, on our first listening trip my wife liked them so much she was good buying 20.7a, we ended up with 3.6s and are content to this day.

Good luck on your journey, research, research, research!
