Thank you all for the recommendations! I picked the Kinki through ebay as I wanted a powerful amp to run my Hedd phone. However I just could not tolerate the weight of the Hedd for a long audition and I would sweat. My dealer took the Hedd back and upgraded me to the Utopia.Hey glad to hear you're enjoying that album! Whilst youre at it, her other album from 2019 is really good too.
Was just looking at your signature and wow I've not seen anyone use that kinki headphone amp until now! I keep going back to the kinki website to look at the ex-m1+ but always overlooked their hp amp offering. How do you find that amp?
As for my own experience, I've only ever tried three tube amps - LDii, WA22 and now WA33. The Utopia sounded great with the wa22 but even better with the wa33. However, I have heard from a few friends who have had the pleasure of trying many amps (including the wa33), and several concur that the DNA Stellaris is still the best amp they've heard the Utopia with. Wish I could get my hands on one to try!
The Kinki is excellent (see 6moons review http://www.6moons.com/audioreviews2/kinki3/1.html)
with ample power and not overly bright but with a powerful weighty sound.
Clearly much better than my Hugo 2 direct to Utopias, added gravitas, less treble sparkle, bigger soundstage. As per 6moons a great pair for HD800's.
As a long time tube fan (Japanese Mactone Pre amp and 300b power amp in my 2 channel gear) I wanted to hear what the Utopias would sound with a good tube.
A friend of mine lent me a headphone amp by a local DIYer based on 6080s to try. It has too much power (it was aimed to drive his Audeze 4's) too much noise, hum but......it sounds wonderful, voices are so real, there is this soundstage and vitality, much more pleasant listen than the excellent Kinki.
So here my problem is that I have no comparison metric for a tube amp as this is a DIY project, I have no clue how it compares with the tube based head amps that are easy to find in the EU (Feliks Euforia, La Figaro, Ayon etc). I am also curious to try integrated tube amps that feed the headphone output directly from the main circuit Primaluna EVO 300, Leben 300 etc.
My tube journey has only just begun, and I am very happy to share experiences and ideas
