CLASS A P3 5670 Vacuum Tube Valve Preamp Amplifier Preamplifier
Description:
It's a very good preamp.it's a new design with better sound quality and beauty exterior,easy to assembling. All electronic component are using professional units.
For example:
1. Fully shielded transformer,and the High voltage filter capacitor using Original Philips BC capacitor.then you can get a pure power from tranformer.this is the basis for pure music output.
2. All resistance using solid core resistance,Safety at Higher Power Resistance builds up as current flows through a wire. that resistance causes heat, which increases as the amount of power increases. Too much heat can cause a fire. Braid-stranded wire carries more power with less heat due to a greater surface area.
3. Audiophiler MKP pro audio coupling capacitor.and nichicon filtering capacitance , be sure the pure music output.almost without any back noise,when you turn volume to MAX.just can listen a little noise floor.
4. About the input and output interface.all using GOLD RCA interface.
