Can you tell me why I didn't like the Reference 3a MM's?

So I recently asked about a new amp on the Amplifier forum.  I got a lot of good advice and ended up with a Pass XA25.  I really like this amp and the sound.  I have been told by Reno Hi Fi, Pass Labs and B&W, all of whom I contacted, that the XA25 is under-powered for my B&W 705S2 speakers.  But it sounds very good.  However a little flat when the volume is low.

So I am looking for some more efficient speakers.  I tried a used set of Reference 3a deCapo MM's, but they did not have the clarity of the B&W's and sounded a bit muddy at times.

I am looking at Omega Super Alnico HO's.  But I am wondering if the full range driver sound is what I didn't like.  

Am I wrong in thinking more efficient speakers will sound somewhat better at a lower volume?  Can you possibly tell my why I didn't like the MM's?  Something about their design or build?

Any thoughts on the Super Alnico HO's?  I don't want to move down the speaker sound chain.

Thanks much!  Any other speaker suggestions welcome!  But not horns.  I am not a Klipsch fan.

jbrrp,

I am limited on what I can do with the room.  Athough I did take a measurement with REW and and a mindsp mic.  However, I am at a loss as to how to relate that to actual room treatments.

The Aric Audio puts out a lot of gain. I have the gain almost all the way down and the volume, even with the Pass, rarely gets past 10 - 11.  It could well be amp/speaker interaction, as I was a bit surprised and disappointed myself, what will all the good reviews over the years.  Not that the sound was bad, just not as good IMHO.

As already noted, an efficient lively standmount is something of a contradiction in terms. There are ways to get around your gain problem too. 
This comment has me scratching my head;
I really need to stick with Bookshelf, as my "listening room" is my garage and the speakers are about a foot off the ceiling and wall for protection.
Protection from what? I hope you don't mean your cars! Placing your speakers only a foot from the ceiling and from the rear wall is inherently problematic. Why? Well for starters that creates a room node problem. Second, most bookshelf speakers are ported and despite their name, never sound best on a book shelf. They need to be away from floors, ceilings, and walls. I am curious as to how you have them mounted there.

I have them mounted on holders that stick out about a foot and are down about a foot from the top of the speaker. They tilt slightly downward towards where I sit and work. 

 Protection from cars, dust, dogs, kids, flying pieces of wood from a saw.  My garage is my space generally, shared with my shop, office, wife's car nights, grandchildren, pets, tools, saws, etc.

Not the best arrangement, I know, but it's what I have and it works fairly well.  I tried the foam plugs in the ports, but the imaging dropped wayyyyy off.

I saw you only had 13 posts and I was impressed by your humble photo/avatar and figured I would try to help you out. You have a lot of very nice gear for that environment. 
With that, I'm out :-)
