MSB:n uusi kuulokevahvistin vaativan kuulokenautiskelijan kotiin. Suunniteltu toimimaan yhdessä MSB:n DAC:ien kanssa. Optimoitu 75ohm ja 150ohm tuloimpedansseille. Class A-luokassa toimiva vahvistin on tehty toiminnaltaan ilman negatiivista takaisinkytkentää. Ohjaa vaivatta lähes kaikkia dynaamisia kuulokkeita. Huippuluokan dynamiikka.

Tinkimätön toteutus MSB:n tapaan – rungoltaan, virtalähteiltään, komponenttien laadultaan ja sijoittelultaan.

Musta ja hopea


Uncompromising headphone performance meets the refined elegance of MSB design.

After years of headphone amp design experience, listener feedback and  numerous prototypes, we’re proud to introduce the Premier Headphone Amplifier. Guided by our design principles, we achieved a perfect balance of quality, functionality and beauty. When paired with our world-class Premier or Discrete DAC, you can experience the finest digital audio on a widely supported variety of dynamic headphones.

The rugged class A amplifier utilizes a unique Zero Negative feedback, high-voltage, current mode circuit that is load independent. The amplifier automatically adjusts to the load that it’s driving without affecting its stability or sound quality.  The amp supports headphones that are spec’d from Mega-Ohms down to a fraction of an ohm. From power hungry planar magnetics to efficient IEM’s, nearly all dynamic headphones are optimally driven. Boasting 134dBA of dynamic range and a high-power class A design, the Premier Headphone Amp easily performs the softest background ambiance to the most explosive crescendos.

High-resolution audio sources shine with our fully balanced architecture, ultra-low noise floor and impedance matched circuit topology. The Premier Headphone amplifier maintains this balanced topology from the input’s origin all the way to its 4-pin XLR output. If single-ended headphones are being used, it automatically reconfigures itself when the ¼” jack is inserted. Experience balanced or single-ended headphones without compromising either one’s performance.

Machined in-house, the sleek unibody chassis allowed us to evenly dissipate heat with an astounding 12,000 in2 (7.75 m2) of heatsink area. With powerful class A amplification, advanced thermal design becomes critical for component longevity and long-term performance.

The Premier Headphone Amp is powered by a custom wound, ultra low-noise, and shielded transformer. To mitigate the effects of residual stray magnetic fields, it’s housed in a CNC machined pocket lined with additional mu-metal shielding. The custom made Lundahl output transformers are also installed in individual machined cavities and located as far from any sensitive input circuitry as possible.  Everything is measured, shielded and optimized for this compact yet functional layout.

Daily headphone use needs to be easy and comforting to use. With the included 12-Volt trigger connected to your Premier Powerbase, the Headphone amp will automatically turn on and off with your system. Forward facing jacks make it easy to plug in and switch headphones, making it simpler to dive into your music.

After a long session of headphone listening, simply switch to the included Bypass Mode to send your music to your desk monitors or home system to share music with friends and family.
