Headphone Amplification

So apparently they followed the "Glass FX" tube DAC and integrated with a headphone amp. Dual 12AX7As. http://www.jolida.com/product/glass-fx-tube-headphone-amplifier

What do you think about a $3000 woo amp? http://www.wooaudio.com/products/wa5.html Anyone at the meet listen to it?

Just picked up a DIY Kludge headphone amp. The base circuit came from a Vacuum Tube Valley #11 on page 24 and 25. Here is the link: https://web.archive.org/web/20131122141643if_/http://www.jumpjet.info/Pioneering-Wireless/eMagazines/VTV/VTV11.pdf A few minor mods were made to improve the performance, such as additional power supply filtering, HEXFREDS, DCed all filaments, etc. This amp sounds great. Has NOS Tung-Sol 6080 and 6SL7 tubes. Has plenty of power. Easily drives Abyss 1266 phi.

Birgir finally has his hands on the SRM727, and evidently does not like the thing at all. Extended comments hopefully coming from the big guy soon. Comments on the 300 should also come soon once he can get his fingers inside the chassis to rewire the transformer. I've come to the conclusion that the srm323 is stax's best sounding amp that is still in production.
