Description
For sale, a near mint Astell & Kern ACRO CA100 Headphone Amp, DAP, Streamer and DAC. Only used to test it is fully operational and in tip top condition. There is one very minor visual knock that I have highlighted in the images. Apart from that it is in mint, like new condition. The CA1000 is a very well specced bit of kit that sets a new standard for headphone amplifiers, providing powerful and clear sound to both headphones and a full hifi system. Can drive pretty much anything you throw at it! From an audiophile home - I am constantly swapping out hifi gear trying to get the best synergy and bang for my buck, be it speakers, amps, streamers and DACS, so please feel free to follow me to snap up a bargain - I tend to sell below market prices and be the cheapest on ebay at time of listing. Happy to demonstrate on pick-up. All my items are sent fully insured, tracked and signed for - or you are welcome to collect. Returns and refunds only accepted (30 days) if fault detected, proved, and if returned at buyer’s cost, including a tracked, insured and signed for service - refund will be flatly refused otherwise - terms non negotiable. All serial numbers are photographed, matched with invoicing and packaging where available and registered on Immobilise. Additionally, items are security marked before shipping, all for security reasons. Strictly no offers, please. Unfortunately, I dont sell to buyers with a less than 18 months track record including less than 30 feedbacks and/or bad reviews. Please take this into consideration as all such purchases will be cancelled and the item relisted accordingly.
