Echo Diastasis PH-79 Incredible Phonostage Open Box*

*This unit is an open box.  We also have a demo unit used at RMAF 2018   
Believe High Fidelity is a purveyor of exceptional equipment in the audio world.  We spend years looking for the best brands in a sea of commodity so that you don't have to. 
The Echo Diastasis brand is one of the gems.  We have demonstrated this top of the line phono in big dollar systems and it has been just as good, if not better, than phonostages 2-3x the price.   We also accept trades for McIntosh gear towards the purchase price.     
Designing a phono preamplifier has always been one of the most difficult tasks in the audio devices design era, because it tries simultaneously to solve a number of emerging design problems, where improvement in one area usually is not working beneficial for others. 
Inside PH-79 there are special enhancement devices, an additional noise rejection stabiliser and a special topology, ensuring that the delicate and low voltage signal of every phono cartridge (moving coil, magnet or iron) in the path to any amplifier, will be free from unwanted and annoying noises. With active equalisation, zero feedback, separation of high and low frequency poles and matching materials, the serious designing issue of the RIAA equalisation is getting resolved with absolute precision
