Exactly to both! However, I think you have 30 days to return them. But Pipegear is just an audio store, so either way, if you have long term issues, you would need to go through Hifiman anyway. But since the $423 one is through Hifiman/Amazon, I would suspect it is a safer route. I got my 400se this way, and I've had zero issues with it.Took me a while! So hifiman (US) sells them $369.00cdn on amazon.ca, with ~$54 import fees deposit + ~9$ standard shipping = ~$432cdn estimated delivery 11nov.
The 399 option is sold by PipGear (ca) for $460 after taxes delivered Oct 28
US Hifiman Warranty vs Canada might be an issue though, HFM not being the most reliable :\ (but ... being on amazon, might still be free returns in case of issue?)
