I am using the Magna Riser Airborne with my LRSs and like the stands a lot. Rob seems to be a straight shooter and has listened to a lot of different stuff over the years.
I’m using the LRS with a Stellar Gain Cell DAC and M700s fed with (primarily) Roon and Audirvana streaming Qobuz and Tidal with a smaller local library of bit perfect rips and DSD downloads. Also using a pair of REL T/5i woofers chosen for the small woofer cones to help match the speed of the planar drivers in the LRS.
Pretty darned happy with the setup and I’ve owned a lot of different stuff over 40+ years.
