I would give them a 9 out of 10 for customer support. I don't think I have ever received a totally DOA product from them or one that died completely within the warranty period. A few times when there were functional issues such as a malfunctioning gain switch on an amp or cosmetic issues such as a scratched up volume knob, they were extremely fast to send in a replacement free of charge to me (and I am in Canada).
The only reason why it would be a 9 and not a perfect 10 is because I have had a few instances where certain non-deal breaking glitches in their products were dismissed/qualified by their customer support as normal. Here are a few examples:
- a Lyr 3 that cut out sometimes and rebooted itself when playing bass-heavy music or games because its protection circuit kicked in
- a Bifrost 2 DAC that had a very low-level coil whine noise in only one of the channels when played at extremely high volumes
- a Modi 3 which had issues with low level RFI interference which is very specific to the location of my house in a close proximity to an airport
- a Bifrost DAC that had glitches when switching between certain sampling rates as the relay did not kick in fast enough resulting in an audible pop through the speakers
Despite these minor problems, I would order from them without hesitation as they are very reasonable and I admit that I am a picky bastard.
