Quote from the Designer

"Luminare is the godfather of the RKV HAA for Headphone Auditions Amsterdam. In contrast to the standard RKV2, the RKV HAA can drive higher currents even to low-resistance loads due to different tube equipment and a tuned OTL circuit design, which is 2 x 8 watts in the best case. In principle, the RKV2 cannot do that because it was designed for high-impedance headphones in 1982.
Stefan at Headphones Auditions Amsterdam had the idea to downgrade the Luminare in such a way that the entire STAX part was dispensed with and only the part that is required for dynamic and magnetostatic headphones.

With this modified concept, all those who did not have a STAX and did not need a STAX could enjoy the performance features of the Luminare.

There is also a reduction switch on the front for the GAIN, so that the volume of low-impedance headphones can also be fine-tuned"
