INTRODUCTION
After the good result obtain with the DAC End I have design with Nguyen Quang Hao a set of boards to create a cheaper project with a sonic performances very near.

INTRODUCTION After many time lost to explore the DAC world from the DAC 1.0 to the DAC Final I have found the end of this way. The No Oversampling DAC give a more natural sound but if you ear the TDA1541 and TDA1543 seem to lose details. The AD1865N-K with passive I/V give a perfect combination, natural sound and all the details.

INTRODUCTION In these years there was many interest about my SESS Tube Headphone Amplifier published on Headwize because it is simple and it give a very good sound. Now I have decided to start a new project using all my new experiences and the best components on the market like the new amorphous C-core by Lundahl.
