high(1000 ohm) impendance headphones on low cost headphone amps

post #1 of 31
Thread Starter 

Hi,

 

I managed to find some pretty good headphones which have an impendance of 1000 Ohms.

Currently i have no amplifier to drive those so i searched the web for something "worthy" and in all honesty, low cost.

Since i had my mind set on buying a dac too for a while, i was pretty excited when i found the aune Mini USB DAC Headphone Amp MK2 SE on ebay for a reasonable price.

The possibility to combine it all with my smsl t-amp (i know i know...) to create a more or less complete desk setup made it look an ideal candidate.

Since the description says it drives pretty much anything up to 600 ohms i'm concerned it might not be the perfect little thingy after all, but since most headphones nowadays seem to be at within that spectrum, i'm wondering if the 600 ohms part is more of a practical reference than a technical reality. My knowledge of everything electronic still is very limited (i'm working on it) this seems to be the perfect place to ask: Will this little chinese gem be a good match for those high impendance phones?

the combo of cheap headphone amps + 1000 ohms already sounds like a disaster.

 

and i didn't even think there where any headphones with that crazy high impedance...

The EF5 docs claim to be able to drive phones up to 2k. Maybe there's some weird ones out there? wink.gif

@Dubstep Girl, you're right, nowadays there might be close to none, there used to be, though, quite a few, even much higher ones. Toshiba HR-V Series HP had an impendance of 4000 Ohm for example.

 

The ones i got here are Toshiba Electret HR-810. Those have a switchable impendance, which is 8, 300 and 1000 Ohms.

While i realize of course i can drive them with 8 and most likely with 300 no problem i ask here for 2 reasons:

 

First, another User here described the sound of those best at 1000 ohms and second, much more importantly, i'm afraid to break something when i accidently plug them in using the wrong setting.

 

@Magick Man: The aune is almost outside my price range already i'm afraid. The most i can put on the table at the moment would be 150-180$, even less without the dac feature.

Sorry, just thought I'd chime in and say that you wouldn't 'break' anything if you plugged your 1000 ohm headphone into an amp that was incapable of driving them... It just wouldn't sound very good... (good being the way it's meant to sound)

 

=D

but those are electrets, don't they need a special amp kinda like the electrostats to drive them?

Wow you found some really rare cans CervAnteZ!

 

It seems like they're some kind of electrostat hybrid of some sort?

I did indeed, and almost by accident. Couldn't sleep the other night and was browsing some fleamarket website and found them offered last november. wrote him, still had them, bought them right away. They seem to be in pretty good shape as well. Can't say anything about the sound yet though, since i don't have them in my hands yet (will though next sunday smily_headphones1.gif ).

This seems to be the specs for those Toshibas:

 

Type: Back Electret

Frequency Response: 20 - 30,000 Hz

Impedance: 1,000 ohm , 300 ohm , 8 ohm

Sensitivity: 104 dB / 100 V rms

Distortion: Less than 0.5 %

Cord: 2.5 m

Wight: 240 g ( Without Cord )

 

Looks like they need a special amp or a power amp.

as far as i gathered they don't. anything they need is built into a special fat plug. the post nihaz supplied ( http://www.head-fi.org/t/183272/elusive-very-toshiba-back-electret-electrostatics ) says so, at least.

I guess what needs to be done then, is to plug them in to some regular source, like a portable player and see what kind of volume they get.

If they require 100v to get to 104dB, the portable player will barely be able to make any sound at all.
