Well, it seems everyone's doing it, so why shouldn't German high-end company T+A have its own headphone system? Hot on the heels of its first headphone offering, the Solitaire P planar magnetic design [HFN Jun '20], T+A also has a matching headphone amplifier, the HA 200 – and here it is. Even by the standards of some of the headphone exotica out there, the Solitaire P/HA 200 duo is pitched unashamedly high: the 'phones will set you back £4800, and this headphone amp £6600 in either black or silver finishes, making the whole system the thick end of £11,500. So you're going to have to be pretty serious about your headphone listening to consider it.
