Thank you all for your valuable feedback and advice.
For AC outlets, I just started using Porter Ports and believe they are really good and in my system, they just replaced Oyaide outlets I had been using for long.
I am not yet happy with my speaker positioning and will need to work on it to get this right !
Thanks for pointing me to the XLO disc. I have a copy of this one ! I remember they had many tracks and I have only used the 'break-in' track so far. Can you please guide me on how to use this disk for speaker positioning ?
For room treatment, I guess I have the same problem as I have the long wall right behind my listening position and there is reflection off of the back wall. In this case, are Tube Traps placed all along this wall in close proximity to the wall ?
