1/10 price for High-End player

It is not a slogan, only. Thanks to the additional board it is possible to transform cheap CD player into high class audio component, capable to compete with CD players costs 2.500€!

There were used best quality components, only. From reputable producers, like: Burr-Brown, Wima, Vishay, Panasonic. The heart of the circuit is, one of the best on the market, 24bit, 192kHz sample rate, advanced segment, digital-to-analog converter from Burr-Brown - PCM1793. If the chip is the heart of it, then Qbacky's filter modules are the soul of.

The market is full of DAC's based on mentioned chip, but this one is an unique, with wonderful sound. Thanks to Qbacky's modules. Hand made, well-thought-out, selected components, in thick copper enclosures - it is a result of long researches. All this measures brought an incredible sound, with wide scene, dazzling reproduced voice and exhibiting all record's details. All esthesis are indescribable during listening music with the DAC. It is just to experience!

High-End RIAA preamplifier

The preamplifier has been a minimalist, primary. An audio section - to keep a short sound path, as well as control - to simplify a handling of it. But in real, simplified, puristic audio circuit needs complicated stabilisation. The unit became to awkward in usage. Also, immensity of switches and knobs is old-fashioned.

Therefore, the micro-controller has been used. It resolved all listed above problems and enabled a lot of useful features, like remote control. Only five touch sensors was used to control the preamplifier. All information are presented on big LED display. Application of modern components increased an usage comfort.

All electronic are installed into a full aluminum enclosure. Audio section and control section are absolutely separated.

The most important - audio part. As it was mentioned above, consist a minimal amount and necessary components, only. All amplify semiconductors are integrated in modules, closed in copper cans. Two per each channel. Thanks to all noted measures, the sound is balanced, incredible deep and natural. From basses to sopranos. It is hard to find other, competitive preamplifier.
