According to Terms and Conditions for Warranty; https://ifi-audio.com/warranty/ The owner is responsible to pay for repairs after the expiry of the warranty period, which is normal for any electric appliances. iFi does not specify the period of the availability of the parts. It means that you may have a chance to repair your old products in future if the part is still available. In contrast, Panasonic guarantees their inventory period of the spare parts after the product is discontinued (5-8 years depending on the product) but you have no chance to repair after that because they throw away the spare parts at the inventory period is expired. I like iFi's vague policy because I will have a chance to use the product longer. Of course, a risk remains in case pro iDSD becomes smash hit in the market greater than iFi expects.
