The M1 gives you plenty of input format choices with four digital inputs: coax, optical, balanced, and USB. Versatility accompanies the connectivity. The M1 DAC will lock on to any S/PDIF signal at 32 kHz, 44.1 kHz, 48 kHz, 88 kHz, 96 kHz, or 192 kHz. The input sampling frequency is displayed on the front panel.

"The M1 DAC's explicit sound should certainly breathe new life into aging CD players," notes John Bamford in his October 2010 review for England's Hi-Fi News magazine. "It delivers distinguished audio with superb detail retrieval and a broad, deep soundstage."

Oversampling 24-Bit DAC
The M1 DAC consists of a top quality over sampling 24-bit digital-to-analog converter circuit which upsamples all incoming data rates to 192 kHz. This is genuine true upsampling and moves the digital artifacts to well outside the audio band, allowing their easy removal without detriment to the top end of the audio band.

The well-tuned filtering circuit results in immeasurably small jitter, noise, and distortion, allowing astounding imaging, detail, and transparency, to deliver all music types exactly as the artist originally intended.

The M1 DAC has been carefully designed to be partnered with M1 series, and also matches well with M3 and M6 series products. These combinations will yield one of the best high-fidelity systems available at any price.

Performance Rivals Any DAC
According to Musical Fidelity's Founder and Managing Director Antony Michaelson, "The M1's technical performance is, pretty well, as good as any at any price. We know this sounds like an incredible claim but it's true." And the company has the track record to back him up!

Musical Fidelity's state-of-the-art circuit design and PCB layout with the use of premium quality digital components gives state-of-the-art performance. "Unsurprisingly, the result is state-of-the-art performance," says Antony. "It's just that the price is competitive so many people find it hard to believe."

Vanishingly Low Distortion
The M1 DAC has vanishingly low distortion, typically less than 0.005% across the band. Frequency response is ruler flat. Jitter is extremely low. The noise ratio is outstanding, making it one of the quietest DACs in the world regardless of price. "Looking at the M1 DAC's total measurements and comparing them to any DAC up to ten times its price you will see that, on balance, the M1 DAC is equal to or better than any," Antony concludes.

Choke-Regulated Power Supply
The M1 DAC has a high quality power supply featuring choke filtration on the mains input. This effectively acts as a an AC line conditioner which increases the performance and value of the M1 to even greater heights.

The choke regulation is derived from the massive Titan power amp and is used throughout the M6 and M3 product lines. As far as we know, the use of a choke filter is unique in a DAC. It filters out unwanted noise from the mains and allows the M1 to work properly, regardless of AC power line irregularities. It makes a huge difference in the sound quality.

Typical choke designs can end up causing as many difficulties as they solve, because they create a magnetic field that has deleterious effects on the musical signal. But the bifilar choke regulation system used by Musical Fidelity cancels out the magnetic fields that other styles of chokes generate. The circuit takes advantage of a tried and true design. The company has been using this technology since 1987.
