ZMF Aegis hörlursförstärkare är ett samarbete mellan gör-det-själv-designern Keenan McKnight (a.k.a. L0rdGwyn ) och Zach Merbach.
Designen på Aegis är helt olik den hos andra hörlursförstärkare.
Med designern Keenan McKnight egna ord:
"It's a transformer coupled amp, but not like all the other ones out there, it's an unusual circuit. The output tubes are wired as a cathode follower, much like how tubes are wired in an OTL, but it is transformer coupled instead. This isn't the case in a conventional transformer coupled amp. Cathode followers have no voltage gain, so to make a transformer coupled cathode follower work, the input stage has to be very high gain, the reason 6SL7 is used. Another unusual bit is the 6SL7 input stage is loaded by a choke, not something you'll see much in commercial amps!
So why go to all the trouble for the transformer coupled cathode follower? 1) lower distortion and output impedance and 2) going cathode follower removes the cathode bypass capacitor out of the output stage that is present in almost all transformer coupled amplifiers. The more capacitors you can get out of the signal path, the better, which really improves dynamics and clarity in my experience."
Förstärkare som Aegis, som är transformatorkopplade, har förmågan att mata ut effekt vid olika impedanser för att matcha både objektiva hörlursströmbehov och subjektiva preferenser, samt leverera riklig effekt vid de olika impedanserna för varje typ av hörlur. T.ex. har ZMF hörlurar med olika behov, som drar nytta av utrymme över sina strömkrav.
Aegis har verkligen kraften, formbarheten och klangegenskaperna så att alla hörlurar ska få möjlighet att glänsa, oavsett typ.

ZMF Aegis Amplifier
New look! Walnut Faceplate, Foundry Copper Vein Chassis and Covers, Copper Knob, Accent Plate and Power Button. I first heard the DIY version of the Aegis Amplifier at CanJam SoCal in 2022. It was a shocking moment for me as the amount of breadth, space, oomph, and realism was overwhelming. Although it was during a show, I would “steal” the seat in the room often to listen as much as I could. And then, also having built up a huge tube collection by that time, once I got one in the shop I had to try the Aegis with all the tubes I had, and all the ZMF and non-ZMF headphones that I could find. Even after all the tube amp collecting and gear that I have gone through, the Aegis continued to make me excited to figure out what I was going to listen to every time because everything sounded exciting again.MFR Info:
Cathode Follower A unique circuit makes the Aegis sound unlike other amps on the market. Tube Rolling Paradise The Aegis is purpose built to sound amazing with stock tubes, or to let you go ham radio crazy and buy tons of tubes for your rolling delight. Each sector; Rectifier, Output, and Input tubes have a plethora of options. Stock tubes are JJ Electronics EL34, 6SL7 and GZ34. Optimized Power With 6 different impedance options based on XLR and 1/4" values this will drive any dynamic or planar headphone, even those in the 75-80dB/mW range! The 4.4TRRRS jack has a voltage divider for sensitive IEMs and headphones. Designed for ZMF The aesthetic design of the amplifier is inspired by aviation dashboards and iconic brands like Chicago's own power amps like Zenith. By integrating elements from vintage audio and the unique characteristics of ZMF, the design will fit in in any environment, be it a hoarders paradise, or a suave modern minimalist chique playground.Amp Performance * Input impedance: 20kOhms * Output Impedance Range: - 1/4" Out: Low: 5ohms, Med: 11ohms, High: 31ohms. - XLR Out: Low: 11ohms Med: 28ohms High: 85ohms * Power: Average of 2 Watts, 1/4" and XLR 1W to 2.5W, calculated based on headphones from 8 to 300 ohms. * Frequency response: -3dB from 11Hz - 33kHz * THD+N at 1mW: < 0.05% * Tube Types: - Rectifier - 5V / 2A types; GZ34/5AR4, 5V4/GZ32, 5R4, 274B. 5Y3, 5U4G -Inputs - pair 6SL7 -Output - pair power pentodes; 6V6, 6L6, EL34, EL37, KT66, KT77, KT88, 6550. * Tube compatibility spreadsheet.
