The Bitzie has an appreciable & supreme overall build quality with perfect workmanship. The outer case is made up of aluminium, and is polished & brush finished; volume knob is rubberized, and has a grippy feel to it. . . . The Bitzie is powered solely off the 5V USB line. This makes it also to work straight off an android smartphones, which is a definite advantage for travellers. . . Lows are strong and fairly accurate and go very deep. Full bodied bass with a ‘punch’. Mids sound clear, slightly intimate & with a touch of ‘valvey-ness’ if I must say. . . Highs are clean, airy, just right amount of sparkle to keep the music alive. . . Soundstage in Bitzie is very good, and realistic and to some extent, slightly lacking in width. Depth is very good. The Bitzie has a fully circular imaging, but gives out comparatively more depth and lesser width in sound stage. Detail retrieval, and dynamics are excellent, way further than any USb powered DAC/Amp I have ever heard. Overall the sonic presentation is very pleasing. Absolutely zero audible hiss/noise, and zero EMI pickup & pops. . . I can recommend the Bitzie for any music enthusiast who wants a compact portable USB amp/dac with high performance aspect. Bitzie is truly like a swiss army knife: very handy unit that fits in pocket & is very well performing. Its workmanship is of high standards, and thus very reliable & robust in operation.

The power, control, bass and treble extension, sound stage and smoothness all took a significant upgrade over the headphone jack from the iPhone/iPod, even over another portable DAC/amp combo I shall not mention. Right there and then I dropped my deposit and will take home a brand new Bitzie tomorrow.

It is one of the most natural sounding DAC's I have heard, I can hear every instrument and sound clearly, with no harshness/"glare"... Connection to my hi-fi amps and speakers was easy with the enclosed adaptor. The same clear and involving sound made the music I played sound great. Room filling sound with a wide and deep soundstage, in short as big as the recordings! It is hard to believe it is a USB DAC

the Bitzie also drove my Audeze LCD-3's with no problem, a very decent headphone output... truly remarkable and a sure winner... it's amazing that such a great sound can be had for such a low price

...the glorious realisation while listening to that album was the accuracy of the guitar sound. Gibson guitars / pickups overdriven into Marshall tube amps give a delicious sound and listening through the Bitzie had the hairs on the back of my neck standing on end...

I have three good DACs in the house - two in equipment costing around 3-4 times more than the Bitzie, and a DAC over twice it's price. Never was the Bitzie outclassed.... I think the Lautus USB cable should be a regular part of the package, though, as it allows the Bitzie to perform to it's full potential. If you don't use a "good" USB cable it'll be like a V8 firing on 4 cylinders

...the best part IMO is how it draws in the listener. Very mellow and musical

British-made USB DAC quality

The Bitzie is a tiny USB DAC/headphone amp for Android phones*, tablets, MAC book, and any PC, MAC or Linux USB port - desktop or laptop.

*requires an OnTheGo adapter - Android Jellybean upwards

Driverless Plug & Play!

Completely driverless it accepts 24 bit 48kHz and 16 bit 44.1kHz (CD quality).

Two headphones!

It has two headphone sockets: 3.5 mini-jack and full size 1/4 inch jack - and can drive both low and high impedance full-size headphones, as well as IEMs.

Hand soldered surface-mount - by our own UK engineers

Active speaker drive!

It is supplied with a stereo RCA jack adapter to connect it to active speakers or a line input on your home audio system - or even to drive power amps direct - and deliver high fidelity sound.

Optical and Coax SPDIF outputs!

The Bitzie USB DAC lets you adapt legacy and SPDIF only DACs to accept USB audio.

Proper real volume control!

Fitted with a real rotary fine quality ALPS analogue volume control - no more fiddly up-down buttons!

Quality components picked for their sonic abilities

It's Z-match too which means it can be used right up to its maximum setting if needed without distorting. Great for maximising volume into 300 Ohm headphones or setting at max out when connected to a preamp input.

Incredible Sound Quality and Stereo Imaging!

Graham Slee products excell in analogue sound quality and superb stereo imaging and the Bitzie USB DAC has to be heard to be believed!

When used to drive our Proprius mini-monoblocks it is hard to believe that its musicality could be bettered.

Music On The Go*

Plug & play tested with Samsung Galaxy S3 running Android Jellybean, S4, S5, and Huawai Ascend G6 (EE Kestrel) using an "On-The-Go" adapter.
Over 7.5 hours continuous playing time from Samsung Galaxy S3 fully charged battery - not a USB hub.

A Note on Higher Resolution Playback

The Bitzie accepts up to 24 bits at up to 48kHz sampling frequency. Higher resolution files WILL play to the Bitzie from suitable music player software (such as Foobar2000 on a Windows device).

However if the software is set to "bit-perfect" (for example when using the Foobar2000 ASIO add-on) higher resolution files will not play whilst that mode is selected.

The S/PDIF coax and optical outputs play out at 16 bit by removing the 4 non-audio bits, and the 4 least significant bits

The difference between 24 bit and 16 bit audio is the noise floor - with 24 bit the noise floor is -120dB (4 non-audio bits ignored makes 20, each bit represents 6dB, and 6 x 20 = 120); with 16 bit the noise floor is 96dB (6 x 16 = 96)

Features

20 great reasons why you should choose the Bitzie USB DAC/External Sound Card...

  • 1.55V rms analogue output
  • Two stereo output jacks

Warning!

This product gets its power down the USB cable. It must not be powered from any external power supply, even if the vendor is using our company name to (wrongly) suggest our approval. Doing so infringes warranty and can cause irreparable damage to your Bitzie.

System Requirements

Please note that this information is subject to regular updating as we find more compatible devices.

Troubleshooting - New Unit Start Up

Because the Bitzie USB DAC is bus powered it has to establish its internal power supply from the computer whilst at the same time having to communicate with the computer.

Initially, the time it takes to charge the brand new capacitors in a new Bitzie USB DAC can take longer than the computer is programmed to wait, and the computer having not received data in time, reports a malfunction.

If after a number of try's at connecting the Bitzie USB DAC, this occurs, leave the Bitzie USB DAC connected and restart your computer. This should allow sufficient time for charging the capacitors and the unit should then work without error.

Operating Systems and Computer Equipment

The Bitzie DAC is plug and play requiring no messy driver downloads on most PCs/laptops/notebooks.

For appropriate operation of the Bitzie DAC one of these operating systems must be running on a host PC and equipped with a USB port certified by the manufacturer. If these conditions are met, operation does not depend on the CPU operating speed.

The Bitzie DAC may work with other PCs and operating systems also, but proper operation has not been tested and cannot be assured.
