Before I purchased my Sopra no2's, I auditioned them at Overture in DE using a Hegal then a Macintosh Integrated amplifier. They were in 2 different rooms, each well damped and setup properly. I wasn't impressed with them in the smaller room using the Hegal. Later I decided to give them another listen in a larger room with a big Macintosh Integrated. There was no comparison. I purchased a pair on the spot. These speakers need room to breathe.
I often see pictures of owners listening rooms with Sopra2's pushed up against the wall, next to a large TV. UGH! I guess the WAF won and the speakers lost.
My setup also has a Plasma between my Sopra's but the speakers are around 5' from the wall behind the TV. My room is 28' wide so sidewall reflections are pretty much not a factor. That gives them room to bloom and couple to the room.
They are also sensitive to crappy electronics. I'm using a Simaudio 700i which is very smooth and powerful and it's a great match.
Also, my speakers took forever to break-in. I lost track of the hours but they are currently 1 year old and have finally settled in.
Nice speakers......I plan to hold on to mine for quite some time which I've never done with speakers before.
