Mikrophono v4 MM/MC Phono Preamp

Our least expensive phono preamp.
It may be affordable, but gives up nothing in sound quality. 
Capable of being used in systems far above its price point.

Uses the same type of passive eq that is used in our more expensive  phono preamps.
  This preamp uses a discrete JFET front end loading system and opamp gain stages to give a clean quiet presentation. 
  Direct coupled with no capacitors in the signal path, delivers tight clean bass, and startling clean highs.
  Unlike some of the less expensive so called high tech alternatives we do not use those cheap plastic RCA jacks. Only gold plated heavy duty jacks used.
  Rear mounted push button to select either moving coil or moving magnet gain and loading, with a very short signal path from the switch.
  Standard loading is 47k for MM and 100 ohms for MC. However MC loading can be changed to anything you wish at the time of purchase. If down the road, the loading needs to be changed, it is a simple matter of replacing two resistors. 
 This can be done by anyone that is good with a soldering iron, or can be returned here for only the cost of the shipping.

All new high ​efficiency double regulated power supply. Produces the quietest preamp so far. No hum, and hiss is reduced by over 20dB.
No wallwart power supply.
We also implemented some changes to the circuit board for a shorter, more direct signal path. 

While the stock IC's are of terrific quality, they are also a cost effective item.
  Recently we have been testing higher performance IC's with a cost no object approach. 
To that end, available now are super low noise high speed opamps that are a major step up in performance. They are vastly more expensive than stock, so they are available as an upgrade.
  This can be done at any time, before or after manufacture.
