The Audio Guild announces the Electro Magnetic Amplifier Co.'s 535SE Headphone Amplifier/Line Preamplifier

SACRAMENTO, CA (January 3, 2017) - The Audio Guild (TAG) and the Electro Magnetic Amplifier Co. (EMAC) announce a new headphone amplifier/line preamplifier designed for the most demanding audiophiles. Designed to capture the magic of the classic single-ended triode (SET) vacuum tube amplifier but without the heat, expense and regular replacement of vacuum tubes, the EMAC 535SE uses a unique and innovative passive/active hybrid amplifier circuit that preserves the extreme simplicity and single-ended nature of the classic SET amplifier. Beautiful "deep vintage" styling pays homage to the venerable triode which saw its first widespread commercial use in the classic "blackface" radios of the 1920s. Built here in the USA, it is available for pre-order now via Indiegogo at a retail price of $1,795 with an early bird discount of $200 for the first 25 units sold. Delivery of the first production units is expected in April of 2017.

"I fell in love with the luscious sound of single-ended triode tube amplifiers, but a couple of 'shocking' experiences as a teen put me off of designing with the high voltages required by vacuum tubes" says TAG co-founder Steve Eddy. But it was this which gave rise to the challenge of capturing the SET magic without the use of tubes. "Initial reviews have been great, and we are excited to get our creation out to more sets of ears."
