PM-1

zero-feedback, all discrete MM phono stage

AudioNemesis is a very young company born after 20 years of experience of the owners/designers. We would like to offer very high quality audio systems at the right price. Our experience in tube and solid state audio (from source to loudspeakers) give us a different sensivity. So, all designs are original, simple, effective. Nothing of the appearence, no slogan. Every product is balanced in designing, manufacturing and sound. We think that balance is the most important aspect, only with balance we can find music. No excess, no peculiarity, no false sound.
We offer several levels. For a higher number you can reach better results and "more" music. Level 1 is the entry level to the AudioNemesis world, nut it has nothing of the standard entry level product.
 
PM-1 is a very special MM phono stage with choices rare even in top of the line creations and never seen before in this class of audio products. No operationa amplifiers, no feedback, no standard low cost parts, passive splitted Riaa. We cut any unuseful part and cost. Our long experience in audio circuit gave us a clear road, and we started developing this product.
 
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. Anything 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 also in cost-no-object products and 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 user in audio output transformers. In order to improve ESR, many low value electrolythic capacitors have been user in place of one or two with high value ones.
Several Shunt regulated power supplies can be found in PM-1. Shunt regulation is expensive, rare and very good sounding. 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, rare also in high cost objects.
