Same here - I got a Purifi ET-400 based stereo power amp from Audiophonics in 2020 because at the time there were no sources (or at least none I was aware of) for a similarly value priced Purifi amp from a US-based seller.
From when I clicked the submit-order button on their website to when the amp showed up at my door, it was only 8 days, which is pretty great for international shipping of an item of that size and weight.
The amp performed flawlessly, and the current version they sell of it is even better, with a slightly improved internal wiring layout and a 12v trigger I believe.
Their customer service is also stellar in my experience.
