Hello all, this is my second post on this excellent forum.


a recent change in domestic situation forces me to disconnect the speaker from my system and use headphone most the time. I understand dedicated head amp is way to go, but i try to minimise the cost next to nothing.

i have been experimenting using speaker output from Creek 4040 amplifier and connected to headphone Senn 580. I am using home made banana-to-6.3mm socket to connect the amp to senn.

I found the sound is very acceptable. I don't know if you have any experience about this and what you think.


cheers.
 
Yes you need to run the amp through some robust 8ohm resistors the aluminium clad 10 watt jobies. Ths ill allow the amp to think its powering a set of speakers and not get up set by the 600ohm ? impedance of the headphones.

Though again I don't claim to be an expert so any one out there shed more light on the subject.

Oh yes shouldn't cost to much !
 
Theres no harm in it as far as I know, it just might not sound as good as a dedicated headphone amp designed for those impedances. Having said that, there is a high end headphone that requires so much power, it needs to be hooked up like this. That particular headphone is the AKG K1000, and resembles a pair of ear speakers.
 
Thanks all for the reply. It is such an excellent forum.

I have been connecting it for a day now, seems ok. btw, the senn impedance is 300ohm.

The volume level is no more than 8' clock and it is loud enough for me to dance around and hear most detail that i normally miss from my speakers ;)

You might think the noise is high as it goes from speaker output, in fact it is as good as from headphone socket in the amp. Yes, Creek 4040 has headphone socket on the front.

If it works fine, i am going to use the same for my main system which is using nait 2 and I don't want to destroy this little cute amp :)

keep me informed guys if you had any experience on such things before i make a serious mistake :(

cheers,
 
I don't think this will cause any problems. Most amps are designed for 8 ohms ... but are ok all the way down to 4 ohms. Impedence is confusing anyway - as the impedence varies over frequency ... so it's not as straight forward as one may think.

However, increasing the impedence from 8 to 300 ohm, shouldn't be a problem. Obviously the amp wasn't designed for this - so audio quality may suffer as a consequence. However, driving a 300 ohm load, you'll be pulling much less current from the amp - so you won't actually do any damage. Someone please correct me if I'm wrong? :confused:

I think you're more likely to do damage to your ears and/or headphones by accidentally turning the volume up too high :)
