Yes, Audio46, where I ordered my Gjallarhorn GH50 JMEs, is not currently carrying the RP, probably due to the Russia/Ukraine war even though they are available direct from Kennerton. You can either order them direct from Kennerton who uses DHL Express for a princely sum of money in shipping charges, or from one of their European dealers. I used Audio Emotion in the UK and got great service and reasonable shipping charges, but you never know these days who might be carrying Kennerton due to the unstable war situation. Their website is

BTW, the RP comes in regular and bass-tuned versions. I have the bass-tuned version and even with its minimal but tight bass I still think it is somewhat light on bass. The regular version IMO would be way too light on bass but I admit to never hearing the regular RP. That said, the RP does seem to produce the bass inherent on recordings, i.e. it doesn't try to add bass where none is present on the recording. Most headphones I have heard editorialize the sound with bass being prominent on most recordings but on bass-heavy recordings it becomes overwhelming. For instance, if you go to a venue with a DJ, initially the bass sounds exciting and satisfying but eventually it becomes tiresome and all songs start sounding the same. Most headphones I have heard sound this way but not the RP. If the bass is there you will get it with the RP bass-tuned version. If it is lightweight the RP will sound lightweight.
