I’m under the impression that how much you use and where you place it is far more important than the particular brand of panel. Most places post the absorption specs for their panels so it’s not really a matter of better vs worse just “different”. (And of course the aesthetic angle).
With that being said, I believe Vicoustic’s analysis and room projects are highly regarded. $150 I think for them to consult on a HiFi room. Their panels are NOT cheap though (I did a consult from them and the cost for all recommended panels would have been close to $20k). GIK acoustics will do free consulting/advice, but I don’t think they’re as knowledgeable (at least in my experience). Though They were more willing to work with my budget of “around $1000” rather than Vicoustics more “we think you should spend $20k and make it perfect”
