Full Balanced Class A Headphone Amplifier
With MOS-FET high current output, PRELUDE's fully discrete architecture features a precise, single-ended balance conversion circuit that renders the single-ended RCA input balanced fully balanced.
The input stage employs a fully balanced amplifier architecture, with precise, single-ended/balanced conversion. The pre-amplifier circuit is independent, adopting a class A output structure, with excellent power and natural timbre.
ALPS Potentiometer
The potentiometer ensures complete and accurate channel balance.
Clean Power
A customized high-power, low-noise toroidal transformer, with multi-channel high-speed low-noise voltage regulator circuit, supplies power for the headphone amplifier and a fully balanced headphone protection circuit.
Aluminum Chassis
The housing is manufactured from a single piece of aluminum which helps isolate harmful resonance that negatively affects sonic output.
I purchased this specifically to drive my Hifiman Susvaras. It is a beast when it comes to power. Even on low gain, it drives the Susvara's effortlessly. The big surprise was its abilities as a preamp. I tend toward analytical sound and equipment that produces it and I found this to be a good non-tube option for bringing in some warmth. I also used this to drive the RAAL interface box for RAAL Requisite SR1a and it works beautifully. At $2.5k it is a true bargain for me. It's winter so the heat generated is not an issue but if heat generation is an issue then look elsewhere.
