Cambridge Audio DacMagic Plus DAC/Headphone Amp (Playback 55)

A New Benchmark in its Class

Consider this DAC if:

• You must have a DAC with a variable volume control.
• You require a DAC with USB, S/PDIF, and Toslink inputs.
• You want a DAC that has both balanced and unbalanced outputs.

Look further if:

• You need a USB DAC/preamp that also has analog inputs.
• You require a DAC that also supports multi-channel codecs.
• You want a DAC with an AES/EBU input.

Ratings (relative to comparably-priced DACs):

• Design & Features: 9
• Tonal Balance: 8
• Timbral Purity: 8
• Detail & Resolution: 8
• Imaging/Soundstaging: 8
• Dynamics: 8
• Value: 9.5

 

BOTTOM LINE

Benchmark, price/performance leader, giant-killer…call the Cambridge Audio DacMagic Plus anything you’d like, but the bottom line is that it can deliver a surprisingly high level of performance and ergonomic elegance at a price that will leave plenty of money left over for the other components in your system.

 

SPECS & PRICING

Cambridge Audio DacMagic Plus DAC/preamplifier/headphone amp
Special features:

• Dedicated Cambridge Audio USB Audio 2.0 Windows driver for 24-bit/192kHz playback on a PC (download available from Cambridge Audio website). 24-bit/192kHz supported with downloaded USB driver and ASIO or kernel streaming modes.
• Mac OSX 10.5 or later supports 24-bit/192kHz USB output natively, so no dedicated driver is required. Built-in driver for USB 1.0 connection (up to 24-bit/96kHZ).

Inputs: three digital audio inputs (one USB input, plus two additional digital inputs—each with its own set of Toslink and S/PDIF coaxial jacks). Bluetooth connectivity is also offered via an optional Cambridge Audio BT 100 wireless Audio Receiver.
Outputs: two variable-level stereo analog outputs (one single-ended via RCA jacks, one balanced via XLR connectors), two (pass through) digital audio outputs (one S/PDIF coaxial, one Toslink).
Data Rates Supported:

• USB: 44.1kHz, 48kHz, and 96kHz at up to 24-bit resolution.
• Optical and Coaxial S/PDIF: 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, and 192kHz at up to 24-bit resolution.
• Internal upsampling to 384kHz/24-bit via Anagram Technologies Adapted Time Filtering 2 (ATF2).

Hello,
The first feature is stated as: "Twin Wolfson 8740 24-bit digital-to-analog converters in dual differential mode for precise stereo imaging."
Please explain how and why "Twin Wolfson 8740 24-bit digital-to-analog converters in dual differential mode" provides "precise stereo imaging." How does the DAC provide that benefit ?
Thank you.

Although Cambridge Audio does not provide any additional info, I suspect the better imaging is due to a better separation and S/N ratio using dual mode processing.

While I do understand the basics of converting from USB to S/PDIF format, why does getting good sound quality (seemingly) require one of those processors in addition to an external DAC after that processor ? Why is good sound quality (seemingly) not able to be generated from an external DAC all by itself ? (or is that simply determined by the DAC's price and brand and circuitry ?) Example: Would I get better sound quality sending the output of my more than three years old Dell desk top PC computer's generic sound card into a Musical Fidelity USB to S/PDIF converter and then to one of these Cambridge Audio DacMagic+ external DAC's via a decent quality USB and S/PDIF cable or by sending the output to a DCS Scarlatti series DAC or an MBL reference series DAC directly with the needed cables ?

I haven't done this comparison so I do not know the outcome.

I do know that one solution as quite a bit more expensive than the other, so economically it's apples and oranges.

Until the pace of innovation in computer IO and computer audio interfaces slows down, it will be very difficult for all-in-one DACs to keep up with single-application interfaces such as USB/SPDIF convertors. By the time a designer finishes the DAC, the front end USB interface is several months old. By the time it comes to market it can be as much as 3/4 to a year old and outpaced by current interface solutions.

I have Audio Advisor (AA) as my home page. One thing that I see very day is that so many Cambridge Audio (CA) components are selling way below their MSRP prices via price cuts from Audio Advisor where the MSRP is shown as being "slashed through" and the discounted price listed. What is going on with AA and CA please ?
