The Mytek Brooklyn DAC+ model has been completely redesigned, and features the latest D?A converter hardware with selectable reconstruction filtering options, improved clocking, restyled analogue circuitry, and a new, powerful headphone amplifier. The unit can also be used with balanced headphones via a special adaptor cable. Other highlights include a certified hardware MQA decoder, the ability to accept DSD audio (in the DOP format), a configurable analogue preamp section, which can accept the output from a turntable pickup cartridge if desired, and the ability to be remotely controlled either via the supplied Apple aluminium remote control, or any RC5?compatible universal remote. The Brooklyn DAC+ enjoys comprehensive digital audio connectivity, with two coaxial S/PDIF inputs (doubling?up as separate left/right SDIF inputs for a hardware DSD source), optical S/PDIF (Toslink), AES3, and USB 2.0. There’s also word?clock (in and out) on BNC connectors to allow synchronisation in multi?channel applications. All the standard PCM formats can be accommodated up to 32?bit/384kHz, plus the three most common DSD formats (DSD64, 128, and 256). As mentioned above, it also supports the MQA ‘master quality’ file format (see SOS August 2016 for more information: https://sosm.ag/mqa?format). For computer?sourced and streaming files over USB 2.0, Mytek have developed a low?latency interface with ASIO and WASAPI drivers for Windows, and Audio Class?2 compliance for Mac OS X and Linux. Drivers and a bespoke control app can be downloaded from Mytek’s web site.The analogue outputs are provided on both balanced XLR and unbalanced RCA phono connectors at the rear, the latter being 6dB lower in level. The two quarter?inch headphone sockets at the front can be used simultaneously and these are arranged to have opposite polarities — the left socket works in ‘absolute polarity’ (ie the signals are the right way up!), while the right socket carries inverted signals. This allows an optional adaptor cable (with two TRS plugs and a four?pin female XLR connector) to combine these outputs to drive a single pair of balanced headphones, if desired. The headphone amp is rated at 6W and is capable of delivering over 500mA of current with a ±12V range in balanced mode.There is an inclusion of a single pair of rear?panel analogue inputs on RCA phono sockets. These can be configured in the operating menu either for normal hi?fi?style line?level input signals, or to work as an RIAA?equalised phono preamp, with options for either moving?magnet (MM) or moving?coil (MC) pickup cartridges. A grounding screw?terminal is also provided on the rear panel. The final connection is a 3.5mm four?pole socket for 12V Triggering, with provision to both accept and generate control voltages to switch other connected hi?fi equipment.The thick front panel is available in black or silver and is machined with an attractive scalloped effect which scatters light in an unusual way. An OLED display in the centre is flanked by pairs of buttons on either side, plus a rotary encoder/switch and the two headphone sockets. The volume control serves as an on/standby switch, as well as for navigating the menus in conjunction with the other buttons.There is a comprehensive menu configures things like the remote control format, the colour and brightness of the logo and OLED screen, DSD and PCM reconstruction filter shapes, converter headroom, analogue/digital volume control, volume control bypass, and output polarity. There are also options to audition the mono sum or stereo difference, as well as to apply Mid?Sides decoding, turn the MQA decoder on/off, configure the internal/external clocking options, determine the output signal routing (line, headphone, both, or auto), as well as input source selection and analogue input formatting. Despite this considerable versatility, the operation is very logical and straightforward, although most things can also be configured and controlled via the optional computer application over the USB connection. Mytek Brooklyn DAC+Designed in New YorkThe only reasonably priced high end DAC with MQA hardware decoder needed to hear full original resolution of Tidal Masters Brooklyn DAC+ is primarily reference USB2 DAC, but also line and phono analog preamplifier and a reference headphone amplifier. It integrates digital and vinyl hi-res playback for reference listening on headphones and speakers. All integrated functions are of the premium grade. Both phono preamplifier as well as a headphone amplifier are of the highest quality, they challenge dedicated units costing thousands of $$.Brooklyn DAC+ features the following improvements as compared to Brooklyn DAC:– Sabre 9028 Pro chipset ( 9018 in older model)– Higher grade, more transparent and less noisy analog attenuator circuit.– Improved analog input performance– Improved Phono Stage transparency– Improved Headphone Amp sound (more detail, more definition)– Dual mono analog pathIn other words Brooklyn DAC+ has the same features as Brooklyn DAC but improved sound.
