Description

For close to the ultimate in affordable DAC extravagance! The new DAC4.1x Professional Edition (finished product) of the all signature DAC4.1x. We took our very popular DAC4.1 and added all the possible AudioNote signature parts along with a gorgeous Silver faceplate- We try to keep this unit in stock and we usually have a few in hand for next day shipping – the kit takes about 3 days to build by hand by our expert craftsman!  Lets start with the over view of the entire kit

All the finest AudioNote components in the 4.1x professional edition – Check out our DIY version in the shop also! AudioNote Non magnetic tantalum resistors along with Kasaii electrolytics (non polar) , AUdioNote copper film caps – Triple  C core transformers , Charcroft Caps on the digital board – truly the kitchen sink of signature components!

Hi ANK,  the DAC arrived today…  Absolutely Stunning !   I am a qualified Electronics Technician (3ys full-time at college) and the build quality is so good it took my breath away – it’s a work of Art !   -Ted Martin 

A stunning Aluminum Faceplate for this finished product DAC with SPDIF and USB – The feature set is HUGE – Let start with the power supply – we use the M2 6×5, ecl82 tube rectified and tube regulated Power supply but we put in the finest components – the AudioNote 1W tantalums throughout along with the 2 Audionote copper film caps .22 and .47 for the ultimate power supply!

Below you can see  the Signature DAC digital board with AudioNote tantalum resistors – this board is professionally built and tested and designed with the AudioNote r2r digital to analog strategy

IV transformers are a proprietary AudioNote design where the very delicate analog  current signal that comes out of the AD1865 chip is run through a high quality audionote resistor to create a voltage representing the Audio signal – this signal is then transferred through a 1:1 (I/V) transformer which allows this ultra delicate signal to land on the line stage fully intact – ready for amplifiation! The IV transformers are housed in a special MU Metal can!

Once past the IV transformers the audio signal is amplified in the output tube stage which comprises of a 12au7 input tube and an ECC99 output stage (DAC5.1 output board) the board uses the expensive audionote Non magnetic tantalum resistors along with the AudioNote copper film caps!

The final part of the output stage is our custom triple C core output transformers for manimum audio performance!  – specially wound on a computer controlled machine for exacting specifications and tensions – the results are awe inspiring for music lovers!
