Hello,
in the rec.audio.high-end newsgroup I found this hints:
MG HEAD DT OTL MKIII HEADPHONE AMPLIFIER
www.divertech.com/aslmgheaddt.html
MkIII version, now even better! All tube SET design with OTL/transformer coupled out puts. Upgraded circuit and outboard power supply.
Have anyone hear this amp?
Sorry - about Cyber I wrote some days before - I have overlook this
CYBER-10 Multifunctional Tube Amplifier
www.opera-consonance.com/products/cyber10usb.htm
Cyber-10, 20 and 30 look almost the same with Reference Series but much smaller---- so we call them "Mini Reference line".
The Cyber-10 is a single ended Class A design without negative feedback, it can use KT88 as well as EL34/6CA7 and KT66. With plate volatge at 360V, EL37, 6L6GC, 5881 can be used actually. The Cyber 10 operate the output tube in UL mode to give 12W power. There is also a switch to operate the amp in triode mode which halves the output to 6W.

Cyber-20 is the first high-end vacuum tube headphone amplifier produced by Opera Audio. It uses two EL84 connected in triode mode single end operation being driven by a single 12AU7. A separate power supply using LC filtering is being used. All connections are by point-to-point wiring. Worth mentioning is, Cyber-20 is the first vacuum tube headphone amplifier in China that uses an output transformer. The selectable output impedance of the output transformer is done by a switch at the front panel. With this switch the amplifier can adapt to headphone having impedance ranging from 10 to 600 ohm. This enable high-end headphone user getting choices over many different headphone in the market. Dual headphone output makes it easy for two listeners to enjoy the music together under the same conditions for easy comparison. The top of Cyber-20 is covered with African solid rose wood. With its cute outlook and small size, an ideal compliment to its warm, transparent and powerful musical performance.
