STAX SRM-500T Will be available from HeadFreaksNew STAX SRM 500TVacuum tube output driver unit for STAX earspeakersSTAX introduces a new vacuum tube output driver unit SRM 500T, the successor model of SRM 006tS. STAX custom made low noise DUAL FET is installed on First Stage and the vacuum tube is installed on Output Stage. STAX continued to use the traditional circuit design which is perfect for STAX vacuum tube driver and improved the power efficiency. Finally SRM 500T achieved the sound quality
