Nice photos but nothing really new brought to the thread.
Oh, just ask !
Driver of the new Magni versus driver of the Gjallarhorn JM Edition (modified)
(New) Magni
Quote Ivan (from Kennerton) : To tell you shortly, it is not a new Magni, the driver is indeed the same as in Magni for now, and that is the only of their similarities. The main feature of this model is that it has an embedded horn, which is actually carved of wood and is a part of the cup itself (I specified on the photo attached).
Driver of the new Magni
The design of the cup differs from Magni very much with different chamber and horn itself, which affect sound a lot. Their bass is very different from Magni's, the bass is much deeper, but due to the cups, it is not overloaded. Magni are much much more neutral.
Le Gjallarhorn
The current Gjallarhorns GH50 page https://kennerton.com/shop/gjallarhorn-gh-50/ Retail price is 1080 EUR, now with a huge discount of 25% for first 10 pcs, as you understand first 10 were already sold, I think the current price will be for a month or so.
There will be at least one another version with another driver, all I know at this point that the diameter of the driver will be different. The design of the cup takes a lot of time, it took 2 months to make current design by constant trial and error.
