Digital Audio Review’s John Darko compares and contrasts the Signature 30.2 LFP-V Edition to one of his 300B single-end picks. You may be surprised at what clean, fast LFP battery-power does for vacuum tubes!

“Red Wine Audio have made a near-flawless integrated amplifier that unflinchingly nails the holy trinity of detail, tube-like euphony and fast, tight bass… effortless, majestic, powerful and delicate. A stunning achievement.”
