A Lyrical Tale of the Beauty and the Beast


Thivan Labs artfully combines a very distinctive and minimalist, highly functional and bold Bauhaus aesthetic with an unmistakable sonic identity … one that, with disarming honesty, infuses the “system equation” with a rich and lyrical narrative … a sonic narrative that is beguilingly poetic in cadence, such that the more you listen, the more lyrical the musical journey becomes !

The DL-50 Anniversary HPA Integrated is derived from Thivan Labs' DL-50 Integrated amplifier.


The Headphone Amplifier circuit is designed to allow the use of 2 headphones simultaneously, and is compatible with HP loads from 32 ohms to 600 ohms. Power output to Headphones ranges from 3.8W at 32 ohms to 200mW at 600 ohms. 

Its 2 x 15 Watt from a Class A push-pull circuit (30 Watt peak per channel), and its 4, 6 ,8 and 16 ohm output taps, allow the DL-50 Anniversary to control almost all loudspeakers currently available on the market without any problems.


As is customary with ThivanLabs amps, the transformers are heavily oversized, and sport very high quality metallurgy, which is what makes this amplifier's superior sound quality possible. Total weight ? No less than 31 kg !


The DL-50 Anniversary is built entirely by hand using a point-to-point method. This results in an extremely durable and reliable amplifier ... one that can operate 24/7 continuously and that is unconditionally stable.  


It's tube compliment -- 4 x 6H13C/6SA&/6080 power tubes driven by 6SN7s, can be qualified as being "recherché" ... French for rare, sought after, exotic and refined. It's sound can be characterized as having enormous dynamic articulation, drive-power, and an impressive command of detail and space ... fantastically beautiful vocals, a deep and tight lower spectrum, and silky highs."
