Agree with you regarding vibration control, it's very importen. I did a DIY for my table shelf to put my gear on with two layer of MDF with dampningglue between and the performance is quit good. My TT is one meter from the speakers and the pickup dosen't jump even at high level of volume. Wasen't interested to buy a shelf that cost a lot of money.
I have vibration control but when I'm thinking a bit further I can't do anything about airborn vibration. Never mind how I twist and turn the airborn problem will allways be there. When I put my hand on top of my CD-players there is a lot of vibration. Isin't this strange 
I tweaked alot before I realized that this wasen't the problem that caused my bad sound in my room so I gave up with the tweaking and concentrated on room acoustics instead.
Agree with you about self- induced and room treatments is difficult to accept for som people. 
Thanks

Wow that is one beautiful room.  I see what you were saying.  It must have been very reflective prior to tuning.  Your treatment no doubt worked sonically but it looks great too.  Is it my imagination or are your VR4 Sr MKIIs a flat black?

You are right Gavin, about reflective. Before treatment there was alot of flatter echo and lack of dynamics in the sound stage that the sound was so terrible that you coulden't listening to music in my room. I do understand when people saying it's to much harshness in upper frequency. As you can see, the reverberation time klerrly proves it thanks to diffusion. High transients is more dangerous to your earholes than loud music being played. I can listening for hours without any pain.
Glad you liked my room.
Thanks
