The hint of classics: 16-bit DAC TDA1541A with advanced octal tube buffer
Something new, something new-old-stock, something borrowed from the past - this is a digital-to-analog converter based on the early D/A chip TDA1541A from Philips. Some people say the TDA1541A is the best D/A converter of all the times. Even if it's not, let's take it as a funny retro project, not sounding bad at all afterall.
This DAC has many digital inputs making possible to use it with many kind of modern digital sources, even DSD and MQA files are nicely playable on computer thru USB and Foobar 2000 software.
The advanced octal tube buffer makes possible to get amplification needed after I/V processing at the TDA1541A's output.
Low distortion tube buffer gives spacious, tonally perfect and outstanding sound with lots of details.
OLED display provides information about digital input selected and digital signal resolution.
