Spendor D9.2 vs Proac D48r

I have the D7’s and have to agree that they absolutely need break-in time, after which the highs soften noticeably. The other issue is that oddly, the drivers seem to need to warm up. I usually will start them playing for 20 minutes or so in the listening room before entering to enjoy—otherwise yes, the balance is tilted towards high with a relative deficit in midrange warmth. I can see this being an issue at a show if they are played cold...assuming this isn’t all entirely my imagination!

The lack of the needed break-in time can be an issue on a show.  
I drew attention to an interesting fact on Montreal show.
Some dealers have a good sound in their room every year, other dealers have a bad sound in their room every year. They change equipment but it doesn't influence to SQ. 

D series have a long break-in time, for sure. Takes the LPZ tweeters hundreds of hours to settle in. Any opinions formed before that time should be put on hold until the speakers are fully broken in (as with all components).

The Spendor classic series is too warm, mushy and slow for me. The D series hits the sweet spot in speed and transparency with mid-range timbre and sweetness.

An update:  I went with the Spendor D9.2.  I couldn't decide and I got a great deal on a premium finish so I went that route.  So far very happy.  And they don't overpower the room...at all.  In fact initially I  thought the bass was a bit light.  Have about 50 hours on them now and the bass is starting to show up a bit more.  But it is very tight, fast bass.  The mids are glorious and the top end is tremendous too.  A very fast "snappy" speaker.  Very transparent. Looking even more to getting them fully broken in, but very happy so far.  And not overpowering in my 12x15 room in any way.
