I purchased this new in 2020 and have been using it. I don't think I used it very often. I was surprised by the difference in sound when I first used it! Please consider it. From Soundhouse below: Features Class A not only transfers data but also considers bus-powered operation, employing 102SSC (Signal 25AWG, Power 21AWG). It achieves fast and reliable transmission, and the stable power supply preserves the sound's contours and dynamics.
