In Stock An In Stock item is available to ship normally within 24 business hours.
Preorder A Preorder is an item that has not yet been released. Typically the label will set a projected release date (that is subject to change). If a projected release date is known, we will include this in the description in red. Other Preorders are set to release 'TBA.' This means that release date is yet 'To Be Announced'. The Preorder can be released anywhere between weeks, months or years from its initial announcement.
Backordered An Out Of Stock item is an item that we normally have available to ship but we are temporarily out of. We do not have a specific date when it will be coming.
Awaiting Repress Awaiting repress titles are in the process of being repressed by the label. No ETA is available at this time.
Expected On When an item is Out Of Stock and we have an estimated date when our stock should arrive, we list that date on our website in the part's description. It is not guaranteed.
Special Order A Special Order item is an item that we do not stock but can order from the manufacturer. Typical order times are located within the product description.

The Musical Surroundings MYDAC II excells with Red Book CDs, MP3 & Internet Music Sources!
Analog-like, extremely natural sound! Experience Fidelity only reserved for the Analog Master Tape!
The Ultimate in Archiving your CD Collection! Highest Quality Sound!

The Musical Surroundings MYDAC II is the first Digital to Analog Converter using Musically Optimized Digital Reconstruction (MODR). Mike Yee’s Musically Optimized Digital Reconstruction technology, developed over the past 3 years, is software driven, executed with a Field Programmable Gate Array (FPGA). The ability to recover low level musical, textural and spatial information buried in digital music files allows the Musical Surroundings MYDAC II to reveal new levels of musical information and enjoyment. The Musical Surroundings MYDAC II features 3 inputs including USB for computer audio up to 44.1 KHz and S/PDIF for high resolution files up to 192KHz. The design allows future upgradability but the strength of this new technology is the unmatched "analog-like" sound it creates with existing Redbook CD, compressed digital music files such as MP3, and internet music sources.

Digital audio and Analog audio have very different distortion characteristics. Digital distortion is lowest as the signals are largest, the distortion is the highest when the signal is small. Analog is completely different, it's distortion is the highest when the signal is the largest and smallest when the signal is small.

To improve the low level resolution of digital playback, a new recovery method MODR (patent pending) was developed to significantly improves the low level resolution. Basically, it is a reconstruction technique that alters only the sub quantization changes in the signal - not hugely different than standard reconstruction, however it is highly optimized for musical signals.

The results are surprising. Listeners expecting to hear the equal musicality of LP experience fidelity only reserved for analog master tape. This digital reconstruction technology is a game changer. Even compressed audio can sound extremely natural.

The SPDIF coax input allows all sample rates between 32kHz to 192kHz, resolution 16bits to 24bit. The TosLink optical input allows up to 96kHz and is ideal for use with Airport Express and Airplay. The MYDAC II supports up to 48kHz/16bit sample rate for USB input from a computer based music server.

The digital signal processing is done in an FPGA in order to minimize jitter. Using an Field Programmable Gate Array (FPGA) allows for complete control timing of the signal processing and removes another jitter source.

The DAC chipset is the TI PCM1798, delta sigma.

The output filter uses low distortion audio op amps from TI (old National Semiconductor). This is the first Michael Yee design using "integrated op amps", which are a high-quality affordable implementation to introduce this new digital technology.

"...the performance is stunning. The sound produced is extremely natural with tons of low level information. This gives a great amount of ambience, so that you can hear into the recording, the background hall or studio and, in doing so, gives great and subtle nuance to the actual music. This is very noticeable in vocals where you can actually hear the throat and chest sounds, and the enunciation and voicing is presented in a very natural but up front manner ( not in your face, but like having a front row seat at a live performance). Singers take on a very vivid three dimensionality, where the listener can sense the body and the face behind the sound." - Audio Direction

"Surprisingly, Mike's circuit excells at MP-3 and other lower resolution downloads. His circuit, while very detailed, makes the lower resolution audible, but in turn actually preserves much of the subtlety which gets completely glossed over by most processors. MP-3 downloads lose more information each time it is copied, but first generation downloads sound remarkably good and many will easily mistake it for a CD quality resolution. If you are into the convenience and desire a higher resolution, the MYDAC may be your ticket." - Audio Direction

"The MYDAC II has stunning performance. It captures low level information better than any DAC in its price range and surpasses the performance of many DAC’s far more expensive than the $1,000 introductory price..." - Audio Direction
