Dynaudio Arbiter power amplifiers

Lesser known Dynaudio Arbiter power amplifiers was a special Dynaudio project. They were build as reference and used while designing and testing their upcoming speakers. They were designed as a character less cost no object amplifiers with the retail price of $240,000. Dynaudio managed to release only 30 pairs.
