Much of the conversation now about these surrounds really expensive tube amplifiers. The system cost of these $6000-$12,000+ amplifiers will limit the audience.
With the Jot R no longer made, it will be important to share info together about what affordable amplifier options work well with the new headphones. Obviously it is subjective, but I wrote that the Magna and Immanis are easier to drive and were less amplifier picky than the SR1a. I am looking forward to learning which amplifiers that are under $1000 (think Schiit Lyr+ for example) work with the new transformer stand for the Magna in particular. It is already an expensive headphone (worth every penny), I think affordable amplifier will open the market for it.
In the meantime, hold onto your Jotunheim R!
I'm so glad I snatched up one of the last Jotunheim A amps when they were on close-out. It's been a really good affordable option for my CA-1a, as it's only slightly different from the R, but it's a bit of a shame they aren't available new anymore.
