Reference 1 is the first reference class line-stage preamplifier offered by JE Audio. Reference 1 employs all-tube pure Class-A single-stage wideband balanced amplifier design. 6H30Pi vacuum tubes are used for signal amplification. No semiconductor devices are used in the signal path. Because of employing just one single-stage, Reference 1 has a lower phase shift compared with conventional multi-stage feedback amplifiers. Additionally, no global feedback is used so that the purity of the musical signals is preserved.

Reference 1 line stage preamplifier is equipped with a proprietary design digital potentiometer for volume control. The digital potentiometer is designed in such a way that it only attenuates the incoming signals but does not affect the signal integrity.

Reference 1 line-stage preamplifier presents lifelike musical quality in terms of transparency, dynamic and extraordinary imaging capability. It will meet any demands for high performance audio.

"if what you’re looking for, first and foremost, is great sound -- specifically, great tube sound -- give JE Audio’s Reference 1 a serious audition. It’s an incredibly good preamplifier for a reasonable price. Its build quality is excellent, its feature set very good, and its sound is out of this world. It’s my top recommendation for preamplifier pleasure for under ten grand." Doug Schnedier of SoundStage. Reference 1 preamplifier received the Reviewers' Choice award.
