AKG K340 and perfect amplifying solution

[afico]

Dear all,
i was wondering which is the definitive solution about the amplfier to make those headphone sing..
I tried an OTL with 2 6080..but the bass is not so nice...
i was thinking to use directly (maybe with some resistors) the speaker out of my venerable Leak stereo 20 (11w)..what do you think?
Thanks a lot

Antonio welcome aboard! It has been a long time since I listened to the K340 and I recall they are harder to drive than most dynamic headphones so a good amp would be needed. Do not know of the amp you would like to use but resistors can and will change the sound. Have you considered the Heed CanAmp?

K340s are a pain to drive. i'm not even sure i have heard them at their best.

I say do it, you may have to do something about possible hum.
The original sales brochure says you can hook them up to power amps.
If you have the amp hand you've nothing to loose.

thank you all for your kind answers..
i just tried with a Nad..but terrible hum and compressed sound...jesus i am really thinking to buy a more sensitive headphone..this is a real finger in the ***

Yeah, K340's need monstrous voltage output, perhaps something OTL would work.

How did you wire it up?
Have you cut the plug off or re-cabled?
Straight out the amp or through resistors?

I was having a very good results with Aspen 823 OTL amp Aspen Audio: Aspen Model #823 Headphone Amplifier.

from GraniteAudio Vacuum tube power amps, tube preamps, silver cables, tube phono preamp, Ground Zero ground loop elimination system, handcrafted stereo systems.

Glad you found a solution, hope you come back and post pictures.

I run my unmodded set with the Heed Canamp and the Sansui AU-D33. It sounds clear enough.........
Don't know how to tell if it drives them fully though. How can you tell?

This thread is pretty old, anyone tried any new amps recently with these cans?

A post on the K340 from the Modern Era!
I've had mine since the 80's but got into them only recently. Only mod is cotton removal. Either that or my FiiO E09K amp is causing bass drum muddiness, in the opening track of Paul Simon's Rhythm of the Saints, for example. They do seem loud enough, cranked up to 2:00 or so. The phones are the gray-driver, bass-heavy version.

Hello, Greetings from Mexico, 
I'm the lucky new owner of a used akg K340, and marked 30 years or so, I have the version bassheavy, I have them connected to a matrix Mstage USB, Gain 18db +, and hear between 12 and 3 to the Pot amplifier. 
Ask enough power, however sound better connected to a receiver aiwa late 80s. 
Greetings and excuse my bad English.
