Superlux HA3D

This is a great item to carry around with you and it can solve a lot of headaches. I use it sometimes for headphones and sometimes to increase the amount of outputs from a mixer for instance. It has a lot of level available so serves as a sort of DI box when there is a mismatch being pro and consumer gear. Lasts a long time on batteries and can work on a wide range of current from an adapter so it's really flexible in the field. I did have to send it back though as the locking XLR would not let the cable go! It's only the second faulty product that I have had from Thomann (in fact I had two Behringer items go faulty too when I think about it but that was a few years ago now). It was sent back for repair and of course Thomann were quick and efficient. Not only is Thomann cheaper most of the time but the service is on average so much better than we get here in Britain. This HA3D does cost more than similar items but it is built like a brick. The only real issue I have is that the paint flakes off really easily. Then again yes we need our gear to look good when performing but reliability is the thing that we MUST have . This does seem to fit the bill. Worth the money.

I bought this thing in order to allow an assistant to hear what I was doing while mixing. It was a bit expensive, but the size, build and features seemed to be just right, so I went with it. I wasn't disappointed - it's heavy, but that's because it's made out of some sort of bulletproof unobtainium plating. It's battery powered, and the battery housing is easily accessible (no screws). It has XLR line inputs, which is perfect, as well as TRS ins, if that works for you. The three headphone outputs have independent level control, which is perfect for when everyone is wearing different models of headphone. Most of the headphone outputs are quarter-inch TRS, but there's a parallel minijack output so that you can plug some earphones in directly without needing any adapters.

All in all, it's a solid unit, and does the job perfectly. Just don't drop it on your foot!

Possibly the best value headphone amp on the market, the HA3D isn't feature packed and offers limited connectivity, but for the right user it may be all you need.

I bought this to sit in my hi-fi rig alongside a couple of other headamps, the excellent ART Pro Audio Heampamp6 and the new Behringer Monitor2USB which has a crossfeed function. The Superlux trounces both in terms of sound, even right out of the box. Used on battery power it is absolutely silent to my ears, through a pair of Sennheiser HD800S's. It's compact and very solidly built, although it does look a bit industrial.

CON's
Nothing at this price!

Just be aware there are no balance, bass & treble adjustment or mono function for critical studio listening. If that suits then I thoroughly recommend this unit and for the other functions there are plenty of rack size units which would happily complement the HA3D

This works great as a headphone amp. Balanced and unbalanced inputs, will drive most headphones to very loud level before distortion, good sound, dual power sources, and runs a long time on a couple of AA batteries.

In addition, I have found this useful for other purposes. Often I need to have a line level volume control, and this works great because of its multiple input and output connectors and battery power. It is also helpful when I need few dB of clean gain, or a way to go from a balanced to an unbalanced line. It adds no hum because it is battery powered.

One nit to pick: I wish the battery cover had a retainer so it's not so easily dropped or lost.

It's a well built and useful box that I would buy again.
