Marantz HDAM-SC Class A discrete op-amp

Replicates the latest discrete op-amp circuit of Marantz.
Used for replacing and upgrading op-amps such as (AMP9927, LME49720, OPA627, AD827, OPA2604, NE5532, NE5534, MUSES03, 02).

Recommended for upgrading DAC decoding IV and LPF analog output op-amps, ES9018, 38 series, AK4495, 97, 99 series, CS4396, 97 series, PCM1702, 04 series and other DAC decoders, digital players, CD players, headphone amplifiers, preamplifiers. Good compatibility, with a significant improvement in sound quality!

Operating voltage: between ±8V and 24V.

It adopts the original Toshiba JFET twin field-effect transistor input, featuring high input impedance and excellent matching compatibility. Operating in class A mode, it helps eliminate crossover distortion. The sound field is extremely spacious, the background is transparent, the high frequencies are delicate and not harsh! The mid-frequencies are rich and full! The low frequencies are elastic and powerful! Sound color style: spacious - natural - refreshing!

Marantz independently developed the HDAM analog amplification circuit, a technology typically only applied to high-end or top-of-the-line equipment. It has abandoned the use of cheap ICs and replaced them with its own HDAM (High Definition Amplifier Module). The HDAM, with its wide frequency response, low negative feedback, and high response rate, significantly improves the sound quality!
