Here for your consideration is Cayin’s flagship tube headphone amp. I won’t go into a lengthy description, suffice to say it is BY FAR the best headphone amp I have heard or owned (and the list is a long one). Will drive anything from Susvaras to Abyss 1266 with ease and utter authority.

Please reference the excellent (and ‘spot on’) review at Enjoy the Music here;

Incredible build quality with custom made-in-factory transformers, specifically built for this amp. Also has provisions for high efficiency speaker out.

Selling this along with the majority of my headphone equipment to finance a dedicated home theater system.

Perfect cond., non smoker, always kept in a clean pet & child free environment.
