The Raal 1995 headphones aren’t your regular plug and play headphones, and in order for your amp to work correctly with the Immanis headphone you need to use one of Raal’s Ribbon Current Drive Interfaces like the TI-1b or their newest one (RCD-32(Ohm)) which you can see in the pictures. Both interfaces work fine, you don’t need to buy a new interface if you have one already. The RCD Interface, featuring purpose designed, highest-quality, toroidal transformers is designed in the style of a headphone stand. Toroidal transformers convert a voltage-controlled amplifier output into a current-controlled signal for driving the ribbons.

You also need to use a special headphone cable as well as an input Cable. You can buy a full bundle with everything you need, so no worries there. If you already have the cables and interface, then you can buy the Immanis only. Contrary to with the SR-1b you no longer may use the open-baffle Compensation Barrels. The barrels will change the intended sound signature but also, because of reducing the level above 2k for about 5dB, they may overload the ribbons with bass when you increase the volume to compensate for the 5dB loss. So make sure to remove the barrels from your SR-1a/b system when switching to the (Magna or) Immanis.
