The ultimate digital product with the ultimate analogue sound.
After the phenomenal success of the SCD-025 Mk.II, Vitus Audio were bombarded with requests to make a version of the SCD but without the CD replay option, literally just a DAC at the same level of performance for those people who no longer use CD as a replay medium. The SD-025 Mk.II is the result.
When Vitus developed the SCD-025 Mk.II they went back to the drawing board and started from scratch, the SD-025 Mk.II has also got all of these benefits. All of the audio boards and power supply were redesigned. The digital audio section has been taken to the extreme.
To minimise jitter, Vitus decided to use a sample rate conversion with a dedicated DSP based module, this module is programmable and upgradeable so as newer standards develop this machine can be easily updated to stay at the forefront of digital technology.
By achieving a sample rate of 384KHz (instead of the more common 192KHz) the amount of bandwidth available increases, so a custom masterclock module was developed to fully support the sample rate conversion modules – this was an expensive way to do things, but when you hear it play music, you’ll realise instantly why they did it!

The external digital inputs on offer are 1 x XLR (AES/EBU), 1 x Coaxial and 1 x USB type B, this USB socket supports up to DSD 128 and 32 bit, 384KHz.
There is also an ethernet socket to give the SD-025 Mk.II a network connection. You can stream Tidal, Qobuz, Spotify, Deezer and Internet Radio via the excellent MConnect app.
There is also a USB socket labelled wi-fi dongle – should a hard wired network connection be difficult, a dongle will allow the SD to connect wirelessly.
