KEF blades 2 or Dynaudio C4?

Mountainsong, what will the distance be from the side walls to the speakers?

1.5 meters

mountainsong,
Did you ever get the opportunity to hear the Luxman monos M900? If so, what are your thoughts?

Mountainsong, if you are on the East Coast we might be able to get a trial pair of Blade 2 for you to try, considering we have most of the line and have a very good working relationship with KEF, we might be able to get a trial pair for you.

We have the big Blades and the Ref 5 so if you want to check either of those out that would be our pleasure. 

As per the Ref 5 we have tried them in our small demo room which is 18 by 14 and they sounded magnificent, in that room, they were about 3 feet from the rear wall.

We haven't heard the new Luxman gear,  we were dealers for the older Luxman gear, we did a shootout of the Luxman C800 vs the T+A PA HV preamp vs preamp the the T+A was far cleaner.

Whatever you decide we would love to be able to assist you if we can.

@mountainsong the 1.5 meter distance from the side walls is OPTIMAL so you will get the most out of these speakers. Too many people make the mistake of putting these speakers too close to the side walls. After more than 50 hours of testing speaker positions, mine are 4 feet from the side walls and 4.5 feet from the back walls. While these speakers are quite sensitive to placement, the good news is that they are relatively light as compared to other speakers in their price and performance range so they are easy to more around.  I chose not to use the spikes and used Stillpoints on mine. If you can arrange for an in-home trial, that would be optimal, but based on what I know about your taste in music and equipment, I am sure you will be very happy with the Blade 2s. I really haven’t heard anything that sounds better at that price point (over even $10,000 more). The Blade 2s have me now engaged with the music as opposed to kicking in the OCD thoughts regarding "how can I get better sound"!

Keep us posted.
