Re: ATS acoustic panels
I have a mixture of ATS, Acoustimac, and GiK in various rooms. They all seem about equally good to me in terms of fit and finish and doing the job they are intended for. I pick the vendor based on who has the color/size I want for the best price. To a first approximation, if I need a single standard-size panel I order from ATS, if I need a bunch of standard-sized panels I order from GiK, and if I have a weird size I order from Acoustimac.
The one place where I think GiK wins is that I cannot express enough how much I hate z-clips. I've reached the point that when I buy from ATS or Acoustimac, I just buy sawtooths and hang with those. Takes about a third the time and a quarter of the hassle.
