If you would like to audition a DAC we offer a 14 day trial period. If it is not to your satisfaction, you can return it and your money will be refunded following safe return of the unit(s). All we ask is that the equipment is returned in the same condition in which it left the factory* and that the client pays for the shipping and any non-refunded bank charges or fees. 
If you wish to return a DAC please contact us within the 14-day trial period. The trial period begins at​ the date of delivery​.
* If the DAC is returned in a damaged state and the damage is deemed not to be caused by the carriage company an assessment of the cost of repair will be made and that amount will not be refunded. ​We recommend that you purchase insurance to cover the return shipment in the event of loss or damage by the carriage company.​

We can accept payment by Paypal, Bank Transfer or Check.
