An experience like no other, and the true magic of the ultra HiFi sound brought to your dynamic headphones…….
Dynamically driven.
Designed to be driven by any high quality Pre Amplifier, and designed to achieve the full untapped potential from your dynamic headphones, the Reference Dynamic Headphone Amp is a fully balanced amplifier.
Boasting 139dB of dynamic range, the amp works in tandem with the Reference and Select DAC, allowing the music to come to life in vibrant and unforgettable new ways.
CNC billet chassis.
Starting with a 65lb plate of raw aluminium, material is machined in MSB’s own in-house CNC shop.
After more than four hours of machining, 60% of the aluminium is removed, resulting in a significantly lighter, more contoured product with the best anodized finishes on the market.
4-Pin XLR
Each amplifier is equipped with three 4-pin XLR outputs, designed for a shared listening experience.
Fully equipped.
A rear-facing headphone jack allows for a cleaner system aesthetic there aren’t any dangling cables interfering with a cleanly assembled system.
The noise floor is reduced with an isolated transformer and grounding scheme. 12 Volt triggers allow remote control over the system power.
Analogue bypass.
If you’re sharing the headphones with a two-channel system, use MSB’s internal bypass we’ve installed directly into the amp. Simply turn off the unit for the signal to be sent to your other system.
