James at Legacy Audio here- I wanted to expound on some things
for the community. The iV4 Ultra version dedicates the whole power supply of an 1200AS2 to supply the exceptionally high current capability. We have the iV amplifier on display in our CA showroom- Destination HiFi. We’ve been testing them thoroughly, here, and the dynamic range the iV amps provide offers huge benefits for all speakers.
Additionally, when you look at the dynamic range capabilities of stereo source material (which is predominantly recorded at 24 bits) and the emergence of streaming high resolution two channel audio as well as Atmos surround sound, using an amplifier that can keep up with the dynamic range is increasingly beneficial. I invite anyone who wants to further understand the advantages of these incredible amps, to stop by and hear what they can do!
All the best,
James
