I see you made the good choice; this Pioneer speaker range is awesome.
Didn't know about them until 2 months ago, up till than we had been auditioning over the coarse of a year many different sets for our new to build HT room. We do need a 7.2.
During one these listening sessions a set of 1Ex's where standing, not connected, in a corner. Since we couldn't find the sound we like we asked the salesmen to hook them up. All I can say it was a revelation, form the first second we knew that this was the sound we where looking for. My wife and I did many blind tests afterwards and came every time back to the 1EX's (with experiences as described in this thread before). In the same shop they also had a set of the slightly smaller brother, the 3EX. They sound very close to the 1EX but miss the sparkle of Beryllium tweeter, however they are amazing as well.
To make a long story short, we go for an all Pioneer HT set-up, with the exception of the subwoofers, which will be SVS PB13-Ultra's in piano black.
So here it is::
Fronts 2x S-1EX-W, Center 1x S-7EX-W, and surrounds 4x S-3EX-W. All of these we managed to buy brand new in a closeout sale for a ridicules low price. The heart of the system will be Pioneers 60inch plasma, the new Susano SC-LX90 and new Blu-ray LX91 player. BTW the W in the code stands for dark wood (all most black) which awesome and very chique.
We can't wait to hear this, but still have to do a lot of work in building the room (in a old farmhouse in the Netherlands) and that wouldn't be finished before Christmas.
