Thankyou everyone,thankyou for your hospitality as well, what do you use under the 103's?, plywood, footer disc?, why does star sound have the same size measurements for all the stands?, do you believe a 103 can support a 180 pound amp?, and still sound the way it was designed to?, or do you believe the 103 is best suited for speakers for best sound improvement?
I use their brass discs to avoid damaging the cork flooring in my listening room. That being said, it is more ideal to spike your carpet and/or floor for room coupling. Those stands can support anything you can possibly throw at them and still operate at optimal capacity whether it be speakers or a dac. I find their effects more pronounced the more vibration you have at work (room>subs>speakers>tube amps>pre-amp>dac).
