What type of headphones are a good match for this amp?

I'm currently using a HD 58X with it, pairs very nicely :)

The output impedance is low enough that you can pair it with anything without worrying about it influencing the sound signature of the headphones. Many "true" (non-hybrid) tube amps have a very high output impedance, which will alter the frequency response of low impedance headphones - the general rule of thumb is to keep the output impedance/headphone impedance ratio at 1:8 or better. Since the CTH has an output impedance of less than 1 ohm, you can use it with anything 8 ohms or higher (which is pretty much everything). From a more subjective standpoint: many people like finding the right pairing of headphone to amplifier, especially with tube amps and their wildly varying sound signatures. The CTH has a pretty neutral sound IMO, with perhaps a bit of coloration in the high end. This makes it a good pair with most headphones, though I don't love it with headphones that already have a little sibilance (the DT990, for example, was not a good match). Headphones that need a little extra emphasis in the treble, on the other hand, sound great - the HD6XX is the most obvious example here. The differences won't be enormous compared to a standard solid state amp like the 789 or a JDS Atom, but A/B testing can highlight the changes.

ReedoI do not have the 6xx, but the jubilee which i am quite happy with so far. How does it pair with those?

It’s a Hybrid, it’s safe with anything it can power.
