Proac D48R

I recommend you to change the stock metal jumpers for better quality ones as soon as the speakers arrive to you because they do degrade the sound severely also Proac speakers are known for their very long burn-in period allow about 500 hours before fully break in( it is also mention at their user manual). 
You made the right choice please keep us update for first impression. 

Congrats Milpai, got to hear the D-48R's briefly and was very impressed.
Agree with itzhak1969, replacing the stock jumpers is a must and yes the Proac's do take a while to break in. At about 100 hours you'll get a better idea of what they sound like. Please keep us updated.

@itzhak1969,
Yes, I will be using the custom made Clear Day jumpers that I am currently using for my Quads.Thanks for the suggestion.

@cmach,
Thank You. Just curious, what was the system that you heard the ProAcs in? Will definetely report back after I spend some time listening to the speakers.

Milpai,

The Clear Day jumpers are an excellent choice. I'm using those on my Proac D-30R's.

I got to demo the D-48R at Audio Revelation. I brought my Manley Snappers along to have some point of reference. The rest of the equipment was provided by Jay at Audio Revelation. I just remember how big and effortless the sounded with great imaging and depth. Due to space constraints I ended with the D-30R which continues to impress.

Congrats on the new speakers!
