Franco Serblin, who passed away in 2013, first unveiled his flagship Ktêma in 2010. He had left Sonus faber, which he founded in 1983, in 2006, so the Ktêma was in development for nearly five years before he felt it was ready to be sold by the new company bearing his name. I remember the tension during its gestation, and Franco's elation at being able to produce a no-compromise system – not that he was ever restrained at Sonus faber. Think of the phenomenal Extrema, Guarneri and Stradivarius. The wait for the Ktêma proved worth it – as did the anticipation lasting a decade to hear a pair in my own system.

Talk to audiophiles that grew up through the 1990s and the chances are they associate brands such as Sony, Yamaha, Onkyo, Pioneer and Denon with meaty AV receivers and, possibly, mini systems. The reason is that it was around this time that the major Japanese corporations began directing their energies into developing products for the burgeoning home cinema market, meaning these younger hi-fi enthusiasts never really saw them flex their design muscles in the stereo arena.

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.

Three thoughts hit me as soon as I switched on the Copland CSA100 integrated amplifier. The first was that it was an all-embracing, do-everything tube/transistor hybrid like the Vinnie Rossi L2i-SE [HFN Jul '20], rated at a similar 100W/8ohm if at a fraction of the price, at £3498. The second was that I want it to kick off a fashion for cool, fully-loaded integrated hybrids because they are the smartest option for offering the best of the tube/solid-state worlds. The third is the realisation that I need to look deeper into hi-fi system building.
