The AudioNemesis PM-1 is a very special MM phono stage with choices rarely found even in top of the line creations and never seen before in this class of audio products. No operational amplifiers, no feedback, no standard low cost parts.

AudioNemesis PM-1

We believe that audio circuits must be designed without feedback. So, the whole PM-1 is zero-feedback, all discrete, with top active and passive parts: Toshiba, Dale, ERO. Everything has been chosen for the music only.

The RIAA equalization is accurate and completely passive. Moreover, it's splitted in two sections to improve accurancy and sound quality. This is a very rare choice even in cost-no-object products but it is very important for the music.
Input impedance can be set choosing between 47kohm and 1kohm, and choosing any combination among 100pF, 200pF and 400pF, for a perfect match with your cartridge.
Intense use of HDG blocks helps to reduce noise and to increase dynamic.

The power transformer of the PM-1 is made with a top quality core, usually used in audio output transformers. In order to improve ESR, many low value electrolytic capacitors have been used in stead of one or two with high value ones.
Several shunt regulated power supplies can be found in PM-1. Shunt regulation is expensive and as a consequence rarely seen. It's difficult to find this technique even in high cost products.
We reduced any kind of noise coming from the power supply in many ways. It's very important to have clean, pure and fast power supplies. To improve the performance, we designed a custom mains filter. Despite the zero-feedback discrete design, the result in noise and hum rduction is a deep silence..
