@donquichotte Someone else being in the room with you can change the sound, making demonstrating your system frustrating unless they turn out to be a good acoustic treatment.
OMG - Room Acoustics are Critical - WAF be dam-ed!.
Just wanted to let my friends on Audiogon know - my wife was gone this week - I moved a LAMP in my living room - Sound stage widened by 4 feet. Mid and high end much cleaner.
Room Treatments do matter.
Wish me luck - she gets home in 3 hours!
Enjoy the music - I am amazed at my playlists - like a new and improved system!
