ART USB Phono Plus PS

We bought these in a rush to use them in a small recordstore for the customers to listen to records with headphones. There arent many alternative products in this price range so it was an easy choice.
We had also a Turntable Lab phono pre which sounded much better but was also more expensive.
We have only used the RCA ins and headphone out. Never needed the usb feature so wouldn't mind if it wasn't there but the other simpler and cheaper DJ Pre II model doesn't offer a headphones socket.
it's a pity it only has minijack input though, in a shop it's not the most secure solution but still after 2 years it works flawlessly even after the minijack plug was hit and bend many times by drunk customers during some events. The monitor output level knob could be bigger of course. On/off switch would also be great too.
Anyway for the price I would highly recommend it.

I use this interface to provide stereo digital IO between an iPad and another audio interface connected to my computer. As such, I cannot comment on the AD-DA capabilities.

Overall it works very well for the purposes I use it for. The sound is clear and the latency is negligible.

The ability to change the clock source and sample rate from the device would have been useful (as I am using it with an iPad and there is no iPad app for it, I cannot change these during use).

For those who are looking to rack mount it: it is quite easy to remove the rubber feet by unscrewing the front or back panel. Once this is done the unit fits exactly in 1U.

Overall recommended if you are looking for quick and easy stereo digital IO.

If you wish to listen to your old LPs on contemporary equipment without phono input or phones, or even digitalise it, this is equipment I recommend. It is easy to use, works well, and has reasonably good sound (of course can not be compared with high end tube pre-amps) if you use it as analogue phono pre-amp with the RIAA correction. Good news is also that it can be used without computer in this case, as opposed to some other makes (e.g., Terrasoniq x64).
I did not carefully read the description and did not notice that delivery only includes USB cable for power supply. But, fortunately, it has a power plug which can use virtually any power supply (broad range of voltages, AC or DC with any polarity - quite interesting and unusual although technically simple). I recommend to order a suitable power supply if you intend to use it offline.
