Naim looks to desktop audio with DAC-V1 preamp/DAC and NAP 100 power amplifier

Naim DAC-V1/NAP 100

Naim has launched its second DAC, the DAC-V1, at CES 2013, which opened its doors in Las Vegas this morning.

The £1250 DAC-V1 is a compact preamplifier/converter, designed for connection to a computer or other digital components, and has its own remote handset, volume control and onboard headphone amplifier.

Partnering it is the NAP 100, a new 2x50W power amplifier also in compact casework, and set to sell for £650. Like the DAC-V1, it will go into production next month.

Naim DAC-V1Naim says the DAC-V1 is ‘designed for the customer who uses a computer as their main source of music’: it has an asynchronous USB input, able to handle audio at up to 24-bit/384kHz, while the five S/PDIF digital inputs (BNC, 2x optical, 2x electrical) can handle formats up to 24-bit/192kHz.

It shares with the original Naim DAC the company’s custom-designed 16x oversampling digital filtering, implemented in DSP on a SHARC ADSP21489 processor which also controls the ‘zero S/PDIF jitter’ system. This takes the incoming data, buffers it, and then reclocks it out at a rate suitable for the DAC and digital filter.

The result is that the filtering and Burr Brown PCM1791A DAC, shared with the NDX and SuperUniti, are completely isolated from incoming jitter, whether the source is an S/PDIF input or the USB connection.

In addition, the DAC-V1 goes to great lengths to isolate interference from the attached computer: it doesn’t use the 5V power line on the USB cable, the USB ground is filtered and the digital and analogue sections of the unit are galvanically isolated, thanks to the use of optical couplings, to isolate noise. Even the S/PDIF inputs are transformer coupled to the same effect.

The DAC-V1 can be used as a conventional DAC into a preamp, using fixed-level outputs, or directly into a power amplifier, thanks to the provision of a digitally-controlled analogue volume control.

There’s also a high-quality Class A headphone amplifier included, with a 6.3mm socket.

Naim NAP 100

The NAP 100 is a dual-mono power amplifier, delivering 50W per channel into 8ohms, or 100W a side into 4ohms.

Described by the company as a ‘classic Naim discrete transistor power amplifier’, it uses audiophile-grade selected components and a linear power supply with a large toroidal transformer, and like the DAV-V1 employs a non-magnetic low-resonance chassis and sleeve, and built by Naim at its Salisbury factory.

I guess because this one is specifically designed for use with computers via the asynchronous link. You could always plug the USB stick into the computer...

Thanks for the info. One thing's slightly strange - all their streamer products include USB (stick) sockets, as does the original DAC. Why not here I wonder.

Yes, it is.

Can anyone get confirmation that the fixed output is available on both the DIN and the RCA output sockets? Thanks in advance. This could fairly be dubbed the rich man's M-DAC.

And I can see the NAP100 going down well amongst those who use the old preamps.

DAC-V1 and the NAP 100 look beautiful Smile

Thanks
