I doubt it. I can place an order for it today. It says delivery 5-7 weeks, which probably just means "it'll arrive when it arrives". This is the norm for many of the US brand amps here in Europe, very long delivery times. But the sales statistics is not based on how many delivered, it's based on how many people buy it, regardless if they have received it or not. So no, I think the sales statistics is accurate.
But sure, I'll give you that perhaps people are not wanting to place orders before they have a lower delivery estimate since you have to actually purchase it full price, not just a placeholder fee, and paying almost 5000 euro without getting anything for it, and no real assurances when you get it, might put most people off.
But looking at Friedman's in general, for instance JEL-20 is on place 107, JEL-50 is at 139, Plex is at 95. Not really selling that many it seems.
Thomann is however only 1 store, hence why I was curious if people are ordering these amps here or if they're just bottom fodder in Europe.
I could imagine that it it could be difficult for boutique Marshall inspired brands to reach success here since the real Marshall brand amps are so cheap so the idea of paying 3 times a Marshall on something that will be more difficult to get support and repair work done on it might not be that appealing to people.
