Tube-Like Sound from Standard CDs with No Oversampling
Pro-Ject's DAC Box S FL is an ultra-compact desktop DAC that provides high quality digital-to-analog CD conversion without oversampling or filtering.
The concept of the DAC Box S FL is based on the original format of the standard 16-bit/44.1 kHz audio CD with a maximum transmitted audio frequency of 20 kHz.
"It's at its best when it comes to energetic, lively music making, in which case it's right on the money, full of enthusiasm and very convincing," notes Richard Black in his March 4, 2010 review for TechRadar.com. "It's so good at that side of things that all our listeners forgot almost completely about the usual hi-fi stuff of balance, detail and so on, and just wrote about how convincing the music-making was."
Four TDA DAC Chips
The DAC Box S FL uses four TDA-1543T D/A chips in parallel Dual Differential Mode, which guarantees high precision and very low distortion in the audible frequency range below 20 kHz. The ultra-low distortion spectrum below 20 kHz is very similar to that of tube amplifiers. Distortion levels rise significantly above 20kHz, which has no effect in playback of audio CDs, because this is above audible frequency range.
The SMD output stage is direct-coupled to DA-converters for best results.
'Extremely Cool' Sound Quality
The sound quality of the DAC Box S FL is 'extremely cool,' even though the TDA-1543 operates best at higher temperature levels. Good heat sinks are needed to deal with heat for safe operation. But this specific configuration has a special advantage. No additional filtering needed! This has positive results in overall sound quality.
The sound of the DAC Box S FL is naturally balanced with lots of detail and articulation, along with strong bass For many audiophiles, this DA conversion principle is the best possible link between the musician and the listener.
"It's at its best when it comes to energetic, lively music making, in which case it's right on the money, full of enthusiasm and very convincing."
"In fact – and this will probably sell a few units sight unseen – it's so good at that side of things that all our listeners forgot almost completely about the usual hi-fi stuff of balance, detail and so on, and just wrote about how convincing the music-making was. Big scale, wide dynamics, natural sound and suchlike were about the most technical comments to be found."
