Up for sale is my Cayin HA-6A MK2 Headphone Amp purchased around 6 months ago locally in Sydney (can provide original invoice) and in excellent condition, apart from a bit of dust...The amp comes with the stock tubes but also have purchased Ray Vacuum Select Tubes - 2 matched 12AU7 and 2 5U4 that...
Are you looking for a fair buy on a serious tube headphone amp? At A$3,000, this lands exactly on the current median of the small comparable AUD set, so it reads as fair rather than a bargain or an overreach. With no spread in the recent comps, there’s not much room to argue for a steep discount, but it also doesn’t look ambitiously priced for a well-kept unit.
This is the kind of amp people buy for its rich, spacious presentation and the ability to bring high-end headphones to life with real drive and tone. If the listing is genuinely excellent condition and complete, that’s the upside here: you’re getting a respected, statement-level piece without paying a premium. I’d just verify tube hours, original packaging, and whether any accessories are included, since those matter more than usual at this level.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
