Vintage Headphones

Jeez how did I miss the original post. Very nice. The original headband condition is unbelievable. The must not have been used much at all. You have the MJOLNIR? I bet that's a nice match.



To update my year old post I bought some AKG K240 ll's for the office and took my Lyr & HP-1's to my Atlanta apartment. Still enjoy them every night.


Thxs fun cans.. I sold the mjo and gun shiit combo some time ago to buy an Oppo HA-1 which I have yet to do. Got sidetracked along the way w a iFi Micro DSD for a while. Right now it's just my Oppo PM-2s f
And my 6plus. Still have the Yamahas, but need a real amp to drive them. Have to say, PM-2s direct from 6plus is decently ok.

did the same with Question and Children's Children...first 2 lp's on my entry level Marantz and Dual/Shure and D/C David Clark aviation headphones.


Awesome.. My uncle had an AR turntable and speakers, Dynaco Tuner and Integrated amp and headphones.. Wish I could remember brand and model of headphones. But he would put on Moody Blues (in search of the lost chord? I think) sit me behind the sofa, right next to the gear, and the music would jump from left to tight, back and forth. As I recall, his albums were very dirty, lots of pops and clicks! [emoji445][emoji443][emoji442] lots of memories.. Oh he had a coo Raleigh '10 speed' bike too, w leather Brooks saddle of course!!

8 ohms is super low head phone impedance. If they are also super efficient a typical receiver head phone output should do well. If they are inefficient they'll only sound their best with a tabletop headphone amp.

This quote from head-fi explains it much better than I can.

Pros and cons of high impedance headphones:
Headphone impedance is usually increased by thinner wire and most importantly more turns of wire in the voice coil. More turns or loops creates a larger field (area of magnetic influence). In layman's terms more magnetic force for the coil to move the diaphragm. Thinner wire usually works out to a lighter, more responsive diaphragm. Depending on the headphone design, this may lead to more accurate response.
The displacement (amount of movement) of the diaphragm (the part that vibrates to produce sound) can be better controlled via a more accurate flux (magnetic field to pull and push the diaphragm).
Difficult to drive for small headphone amps with low output voltage and low gain.
Most high impedance headphones need an amplifier with higher voltage gain and higher output voltage, e.g. the 600 ohm Beyer DT770/880/990 series.
Allow Solid State Op Amps to work more efficiently with less distortion. Have a look at Op Amp data sheets and a graph of distortion vs. output impedance for most audio Op-Amps and you'll get the idea. This is a very complex subject, but most Op Amps are designed to output (typically) up to 10 Volts into 600 ohm loads or higher.

Pros and Cons of low impedance headphones:
Headphone impedance is usually decreased by thicker wire and less turns of wire in the voice coil. The magnetic field is built up by more current.
Easier for small and/or portable headphone amps to drive. For example: an iPod or MP3 player headphone jack. Many small and/or portable headphone amplifiers are designed to output a volt or two into low impedance, high efficiency headphones, e.g. Grado headphones.
Low impedance, low efficiency headphones usually sound better when driven by a desktop amplifier, e.g. Audeze LCD-2 or AKG K70X.
Low impedance headphones usually sound better when driven by a solid state or a transformer coupled vacuum tube amplifier. Low impedance headphone do not usually work well with Output Transformerless vacuum tube amps.
 
Pioneer SE-20 here. Got them for the look, sounds is quite dreadful, looking for an upgrade :D

hey what headphone amp do you use with those DR-7 i have been looking for something better than my preamp for a headphone option

Straight out of my Receiver a Viking SC-5814 I like their sound that way:)
 
Earspeakers: Stax SR-X Mk3 (1975) and SR-Lambda (1979)
Energizers: Stax SRD-7 (1971) and SRD-6 (1973)

They sound pretty damn good for their age :)

Had a set of SE 50's that sounded pretty good but these are not lite weight headphones. Would not want to were them more than an hour.
