Vacuum tube amplified headphones...

I am now a headphone fan because fate take my acoustic room and speakers away, but with the AKG K340 hybrid, my actual system beat my tuned speakers/room , and to beat my K340 someone will need a dedicated acoustic room with speakers way better than my Mission Cyrus 781...Cost : over the sky...( ask an acoustician how is the cost a dedicated room, and if you do it yourself , i takes me at least a year full time of listenings experiments to figure out and tune my resonators )

Cost of my Akg K340 : 100 bucks ...By the way the bass i hear correspond to a subwoofer arrays...but it vtakes me 6 months to peut them on their optimal level ( 6 modifications) Nothing is easy... But it is more simple than speakers/room well done...i dont think that in S.Q. many headpgone can beat them, after all they were compared to Stax omega  favorably because of deep bass impact and holography and electrostatic highs and this 45 years ago without optimization...

@pindac , that's what I've read about ribbon 'phones, but haven't had the experience....nor esl types, the cost of which is not in my budget...

'scuse...

@ghdprentice , here's one version of that cartoon; there's an LP variant of an iPod that's cute....

....and those K/S VT 'phones will mate seamlessly to this little marvel....

....tangital tracking available on the V3 model....

@asvjerry The DIY Ribbon Speakers were a follow on to an investigation into building a Stax Type of ES Headphone, from recollection there is a Part that can be purchased very cheaply that enables the Stax ES Type to be produced.

It become apparent, both the ESH and RH DESIGNS, could have all parts required prior to assembly purchased for approx’ £100.

If the most desirable aesthetic is wanted, the price will inevitably increase.

The owner of the Stax ES Headphone was absolutely lost for words, when the discovery was made that the Ribbon Type was bettering their Headphones at approx’ a twentieth of the cost.

The same builder of the Headphones is also the Builder of the other devices I mentioned earlier using the Korg Nutube.
