xDuoo TA-20 Balanced Tube 12AU7 Headphone Amplifier. I bought this directly from the xDuoo store on 12th April.  Very nice headphone amp when paired with my LSA HP-3 (= Kennerton Magni) headphones.  I'm only selling now as I have a vintage preamp (Yamaha CX2000) arriving soon which has a headphone socket, and this will be enough for my needs.  I rarely listen to music through headphones. 

This will come with the stock valves (unused), and the original box.  Location = Colchester. Price = £250 + £12 postage to mainland UK.
 
The TA-20 won an award from Headfonia for best headphone amp of 2019.  I have copied the text below from the Headfonia website.  
 
Best Amplifier


Tube: xDuoo TA-20


The xDuoo TA-20 takes what made the TA-10 a great amp, to the higher ground. It can drive virtually any headphone you like, or want, with a sound stage much wider than its transistor competitors. True, it’s not a full Tube amp, but that’s also what makes the TA-20 affordable (and compact).

Build quality is still astounding, with real attention to details and a comprehensive layout. It’s not the most transparent amp you can get, but that’s the magic. If you’ve never had a tube amp before, maybe this should be your first one, even more, if you own a planar headphone.
