Do Not Trust This Company For Online Purchases
I bought an opened box iFi DAC from this company. It claimed it was like new, but when it arrived, it turned out being defective. I've owned many DACs and have been enjoying DSD files from my PC for years, so I know how things work, and how they are supposed to sound. After experiencing issues with the device, I contacted HFB. They told me they'd 'run tests' and what not from their end on another device. They never did. They never got back to me until I decided to return the device, for which they had me pay by the way. So it cost me over 20$ shipping to return it to them. They finally refunded me the price of the item, but refused to pay for shipping. They claimed that the said device worked properly, insinuating that the issue was on my end. I'm playing all forms of DSD as I'm typing now without the issues the iFi had.
I wrote to them to ask for a complete refund and they simply ignored my email and brushed me off. I will never do business with these guys ever! Their loss in the end.
