Audiovalve RKV Mark II

The RKV is a powerful high-end OTL (output transformer-less) tube-driven headphone amp that uses a unique and patented circuit where an OPAMP biases the tubes. It comes with an optional Impedenzer allowing it to drive low-impedance headphones (below 100 Ohms), the AKG K1000 and speakers.
