Audiosector TDA1543 NOS DAC   2011

 

My first experience with the TDA1543 IC was not really favourable... see my experience with the Valab TDA1543 DAC.

The world of digital music reproduction is moving fast and chip technology advancing in big steps, but at the time the market seemed to be dominated by inexpensive chinese offerings and the Buffalo DAC's.

Searching all available options I was quite intrigued by the minimalist creations of Peter Daniel and choose to try one of his Audiosector NOS TDA1543 DAC's as a first serious foray into computer audio. It seems that I got one of the last units he sold, fully packed with genuine Black Gate capacitors and, on request, with a discrete Bobken regulator for the digital section.

I mounted the DAC board on a CNC cut bottom plate with copper feet and cased it up in in a housing made of two blocks of modelling hard foam finished in very rare Amboina, with a black perspex element down the middle for visual contrast and smoked panels front and rear.

Connecting the DAC to my transport was done via a battery powered M2tech EVO USB converter.

 

The Audiosector DAC certainly delivered what I expected from it with its natural and energetic presentation. You could definitely hear the break-in phase of all those Black Gate caps since at first it sounded quite grainy and congested. A few weeks later that turned into an open soundstage with very nice pace and rythm and a great sense of authenticity. It was a small step up from my previously use CDP... but then: computer audio is advancing fast!  :)
