Front End Audio acquires previously owned gear through our Buy-Back program. You can purchase used gear at a great price but there are no manufacturer warranties with these items.

This Black Lion Audio B173 looks and functions just like new and comes with everything as if you were to purchase it new. Awesome deal!

The Black Lion Audio B173 Preamp is one of the most "bang for your buck" preamps in existence, and is now available in the 500 series format. The B173 not only delivers the beefy lows, buttery mids, and polished highs of a classic 1073 preamp, but does so at a fraction of the price! The preamp and line amp circuitry found in the Black Lion Audio B173 500-Series is identical to the original B173. Not a single component or design feature was compromised while converting it to a smaller package. As a result, the circuit boards are jam packed with all sorts of delicious components, including a brawny Cinemag input transformer!

The power supply is the backbone of any preamp design, and can make a huge impact on the overall sound and performance of the preamp. The +24V rail needed to power the B173 500 is painstakingly converted from the +/- 16V rails of a 500 series rack using a custom DC-DC converter circuit specially designed to keep any unwanted noise or modulations out of the signal path. Complete isolation is then achieved through the use of inductors, ferrite beads, decoupling capacitors, power regulation, and a custom enclosure surrounding the entire circuit.

The Black Lion Audio B173 500’s “Class A”, discrete circuitry combined with high-end components provide a fresh approach to a classic sound that won’t disappoint. Thanks for your purchase and continued support of Black Lion Audio!
