I must add just a few things but the text is as, though some additions re: measurements to be added.
I started impressions at the TouchMyApps forum. I'll have a full review later in the next few weeks. I think this product deserves the ink space and will find many fans as it breaks the mould. How is this? Well, it's an expensive product, selling from 400-700$ depending on where you are and what unit you choose. But rather than going the very tried road of all-out benchmark performance, VorzAMPpure and VorzAMPduo obviously plow their own sonic signature, and it's no an accident. It is wonderful.
Vorzüge are a new company out of Germany. The VorzAMPpure and VorzAMPduo are their first products. They are (I assume) new to most people here at Headfi. e-earphones, Fuji-AVIC, Musica Acoustics, and who know else has them for sale and testing.
In Japan at least, the Vorzüge is quite popular despite being expensive. It is tiny, compact, and delightful. I need to go back to spend more time with a sample. If you go to any of the above stores you can try one out. I assume people here will also be getting them soon as they are excellent. As an amp-only unit, I've not been this excited for a long time. There are very low levels of noise, maker-tailored low and high frequency rolloffs, and from my other listening observations, a slight amount of harmonic distortion in the signal.
Whatever the tech spec says, it has a sound all its own, erring towards a wide, taught mid range, and secondarily, extended, but extremely smooth highs.
I've got not much more to say other than the DUO version has EQ switches for bass and treble, and has major impact. I find the treble switch introduces a bit of background noise, and probably sits at around 5-6 dB increase, while the bass switch plows through your head, possibly serving up ~10 decibels of jaw-shivering bass. It is a more intense version of the Graham Slee Voyager. Well, as far as the contour is formed. As far as coherence from bass to treble, the Vorz amps are smoother, easier to listen to.
A size comparo with ALO The National and GoVibe Porta Tube+
NOTE: Vorzuge contacted me to say that if anyone wants their gain lowered, Vorzuge will do it for free. So, go ahead and buy with confidence.
More impressions welcome here!
Remember, full review is up at TouchMyApps.
