Product Details
The MD300-APS is one of the larger scale products in family of vacuum tube Stereo
Pre-amps from Ming Da. Through its unique 300B or 2A3 amplification architecture,  
the MD 300 APS brings the best that those tubes have to offer to amplifying low level
preamplifier signals. It boasts a higher dynamic range than most preamps on the
market.   

On the functional side, the MD 300 APS has four inputs and two sets of outputs for
driving amps and subwoofers.  There is a bias switch on the back for choosing 300B
or 2A3 amplifying tubes.  A remote is included that operates volume and muting.  To
further quiet tube microphonics, high quality tube ring dampers are included.

The MD300-APS is made up of five high fidelity Vacuum Tubes over three different
types, catering for a greater range and depth in sound, and providing an optimally
natural sound reproduction.  A pair of low noise 6SN7 tubes are the first stage of the
amplifying chain that feed either 300B or 2A3 tubes (see “Tube Righteousness” to
determine which tube is right for you).   An easy bias switch located on the back of
the preamp, allows you to switch between the two handily. The  MD 300 APS also has
a stunning frequency range between 5Hz to 150KHz and good voltage gain; while the
natural quality of sound reproduction in the MD300-APS is helped by negligible
distortion and Signal to Noise Ratio.

A wide input voltage range of between 100mv to 1000mv, high capacitance and low
output impedance makes the MD300-APS high on efficiency while designed to retain
as much original sound as possible.
The MD 300 APS has 4 inputs and two outputs, muting and remote control
Uses a “short signal path” design in that the 6SN7 tubes immediately feed the 300B / 2A3 tubes ampliifiers
Is available in a variety of tube configurations – see “Tube Righteousness”
