BMC PureDAC - Digital to Analogue Converter, Reference Level Headphone Amplifier and Preamplifier
 
Only $1,690.00
Plus, Free Shipping in the U.S.!
 

Preorder Now - Expected Delivery - Now September 2013

 

*NEW* The B.M.C. PureDAC delivers a DAC of the highest quality. The PureDAC combines its DAC with a balanced preamplifier, a reference-level balanced headphone amplifier, and B.M.C.'s exclusive Digital Intelligent Gain Management (DIGM), a volume and amplification control system that calibrates gain without dividing or downgrading the input signal.

 

Features:

Top-grade Digital/Analog Converter with Current Injection current-to-voltage (I/V) conversion

 

High-resolution asynchronous USB interface up to 24bit/192kHz

 

ASIO driver for Windows; Linux and Mac compatible

 

AES/EBU, coaxial and Toslink digital inputs

 

Balanced, reference-class headphone amplifier with digital/analog power convertion (DAPC), load-effect free (LEF) technology, a lateral MOSFET, a super-low impedance LEF output stage, and lossless Digital Intelligent Gain Management (DIGM) volume control

 

Balanced LEF, CI-compatible preamp that optionally operates in B.M.C. Mode, with DIGM and a vertically diffused metal oxide semiconductor (DMOS) and LEF-balanced output stage.

 

Separate volume controls for the line and headphone sections

 

Second-generation DIGM with optimized gain distribution between power amps and internal and DIGM volume levels

 

Optical B.M.C. Link for connecting with B.M.C. amps like the PureMono

 

Remote Control

 

Massive and stylish extruded aluminum chassis

 

Dimensions: 14.37 x 4.06 x 12.91 inches, W/H/D (365 x 103 x 328 mm)

 

Weight: 11.9 lbs (5.4 kg)

 

The PureDAC's balanced preamp is integrated with the DAC's current-to-voltage converter, which converts and filters the DAC's current, eliminating the need for an extra stage. The Preamp and headphone amp both employ B.M.C's exclusive Load Effect Free (LEF) technology that handles a speaker's current demand separately from the voltage demand, increasing the preamp and amp's efficiency and the quality of its audio reproduction.

 

The PureDAC also boasts separate volume controls for the preamp and the headphone, a high-resolution asynchronous USB interface, digital AES/EBU, Toslink and coaxial inputs, balanced analog inputs, RCA output jacks and a special B.M.C. link for connecting directly to a B.M.C. amplifier.

 

Its balanced output is ideally compatible with amplifiers featuring B.M.C's exclusive Current Injection (CI) technology, which enhances signal purity and the musical presence of the PureDAC's audio reproduction.

A few notes, the pictures show a 3pin XLR. This is incorrect and the Unit will have a 4pin Female XLR for balanced operation. Some more details just in from BMC. See below.

 

 

Dimensions: 365 x 103 x 320 mm
Output Impedance:
    Balanced headphone < 1 Ohm
    Standard headphone about 100 Ohm*
* This is a new approach of a quasi balanced standard output with a floating mono GND. It sound clearly more quiet and dynamic compared to the standard solution.
Upsampling: None! Asynchronous upsampling is always a sound degrading procedure unless you need to reject a bigger amount of Jitter.
USB: Asynchronous of course, going even further: We managed to use a unified clock for the Sabre DAC and the USB, so the internal Sabre DPLL isn't needed.
DSD: One reason for the delay is the implementation of DSD. Hope it will be finished quickly.

The headphone amp has a very unique approach. Of course it uses our LEF circuit, therefore it is a single ended class A performance without a feedback loop. The amp itself is a part of the DAC's I/V converter, so the DAC goes directly to power without any extra stage. Usually you wouldn't use big transistors for a headphone amp due to their capacitive load and bandwidth; but in this configuration we need to perform the bandwidth limiting of the I/V converter. This means PureDAC is using 8A output devices (!!!) of a special and rare kind: Lateral MOSFET, known for fantastic sound quality (you can see by the specs), but having some problems of delivering very high power due to saturation limitations, which is true for speaker but never for headphone drive.
This is why we can enjoy all the sonic beauty of this solution without any drawback, and also dare to offer an output impedance close to zero, delivering a fantastic control!
The XLR line out uses an LEF vertical DMOS-FET stage. Unique and challenging any preamp available regardless of the price. 

PureDAC is designed for balanced use and any other use would be a waste. It is true high end and should be used and combined accordingly - once you see an inside photo you will understand how different it is.

Concerning the power it simply a question of impedance. The voltage range is always the same and due to the very low output impedance just the headphone determines the maximum power by it's current request. For low impedances like 32 Ohms you better don't use the very high volume levels.

PureDAC features our exclusive DIGM, so you don't need to worry about impedance / gain matching of headphones.

Expected delivery on more units of the BMC PureDAC with DSD decoding is mid September 2013.  Moon Audio has a demo unit plus more are on the way.  The final production unit won't be available until the middle of Sept. The first shipment leaves Aug 15 and takes about 3-4 weeks to arrive via container ship. 

 

  

 

The PureDac is fantastic and probably the best value in combo units especially since it is balanced and also does DSD decoding. 

 

 

 

Thank You.
