DAC End 2

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.

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.

The AD1865N-K give the better performances with a 200ohm MK132 Caddock as passive I/V.

In this configuration the output signal is too low to drive any amplifier so I have design for the AD1865N-K the better output stage.

This DAC use a single ended vacuum tube amplifier without the expensive output transformers used in my original DAC End.

The DAC board follows the original design but has been inserted a jump to switch the phase of output signal.

In any vacuum tube stage the signal on the anode is in out phase...
