- The Circuit is specifically designed to provide sufficient amplification to match your cartridge with the rest of your system.
- Each unit is hand built “Made in the USA”.
- 50 hour factory burn in on all circuits and vacuum tubes.
- A low Noise level of -75 dBu below maximum output allows the quietest passages of you music to be heard.
- The output circuit is designed to drive your cables and isolates the output from the influence of the next stage.
- RCA connectors are high quality, Gold plated, recessed with an isolated ground.
- Isolated ground RCA connectors plus the Ground On/Off switch will allow you to choose the best ground configuration.
- Recessed RCA connectors are durable and will hold up to the typical Audiophile who loves to change their configuration.
- All switches and knobs are easily accessible, nothing hidden inside to adjust.
