I just got the Lehmann Traveler a few days ago. Interesting amp. Great physical quality in a tiny 'brick'-like form. Attached to a DragonFly DAC, the sound is even more detailed and crispy than the already-crispy DragonFly's headphone out. Attached to the iPhone 6s-plus headphone out it's very smooth and seductive - amazing to hear when playing Dark Side of the Moon. I ordered a FiiO L3 cable, to use with the Apple Lightning to 30-pin adapter, so I can feed an analog signal to the Lehmann and bypass the iPhone's volume control. Presumably the DAC in that Apple adapter is the same DAC that's in the phone itself, but we will see. The 4-inch miniplug-to-miniplug cable supplied with the Lehmann is a wonder in itself - looks very expensive.
