LampizatOr- BEST300B DAC Manual
Introduction
Thank you for choosing the BEST300B (Lampizator) DAC. We created it with huge
research effort to deliver not only world class musical performance, rivalling the most
expensive DACS money can buy, but also to offer very long life of the product. Simply
speaking – if you adhere to some basic precautions listed below – the product should
last a lifetime and hopefully in this period – will never be outperformed by a competing
product.
“Whose lifetime?” one might ask – well – let’s not go into details – enough to say it
should work flawlessly for the foreseeable future.
We can’t be 100% sure, but it is extremely unlikely that the market and the industry in
the future will embark any technology of music storage faster than 192 kHz and with
more resolution that 24 bits. We already hit the human ear limits, not to mention the
real needs of mass consumers (MP3).
Data formats
The DAC is capable of automatic recognition of all sampling rates from 32 to 384 kHz
and bit rates from 16 to 32. Since few if any transports offering SPDIF format of the 192
kHz exist in the consumer market, it is hard to guarantee the operation but on the
professional ones which we tried – it worked. From our experience the transmitters of
SPDIF are incapable of making good square wave over 48 kHz, so if you play a 192
kHz file, be aware that on one hand you “play” more detailed data, but at the same time
your signal is waaay more distorted so at the end of the day for this reason alone it
may not be worth it to chase the hi-rez rabbit.
If you use USB connection, all our DACs will play up to 384kHz and 32 bits. This
theoretical limit does not imply that you need RECORDINGS of that resolution, which
don’t exist by the way, but that you can use up sampling to play regular files. We
however listen to all recordings at the resolution settings they were recorded.
By PCM files we mean all known file formats like: MP3, MP4, Aiff, Flac, WMA, WAV,
Ogg, Ape and many more less known types. PCM abbreviation stands for pulse code
modulation.
DSD
Direct Stream Digital, also known as DSD format - this format is not new as many
people think, it is as old as digital but it wasn’t used for consumer audio or home audio
- before. It became very popular after 2010 and continues to make its way into our
homes. It is VERY different than our well known PCM format as found in our CD files,
MP3, FLAC or WAV - AIFF. It encodes the music in the data stream differently, looks
