Excellent. This has brought the improvements, I wished smsl po100 I bought earlier, would. It does what you guys said it would, clarity and precision is next level, I got better separation and layering out of the music. Voices are really smooth and full sounding! But YMMV, my system is little more complicated now, starting PC + Altor USB Isolator + iFi iPurifier 3 + SMLS PO100 2024 + Audiophonics DigiRescue, all this powered by iFi iPower X 5v + some supercapaticors, coaxial to Topping E70V and Audiophonics HA-B6102 + Burson V6 Vivid + Quad Era-1 / Audio Technica WP900. And I am really impressed how my headphones sounds now, thank you Audiophonics! Peace.
