Well, it seems that I agree with everything you've said.

 

Still, Donald North thinks the 250 ohm versions sounds the best.... expectation effect maybe?????

I go with what sounds better to me and I prefer the sound of the 250 ohm version, while others in direct comparison have preferred the 600 ohm. To each his own. I have consistently said the 250 ohm version sounds like it has more treble energy and my measurement findings support this.

 

I recommend people get their own equipment and measure and compare the two for themselves.

Is that the '03 880 or the '05 880?

'05. I've never heard the '03 and am curious how it compares.

A further thought on this subject.

 

To be fair, despite my objective position that all 3 impedance options of the DT880 are virtually the same (or actually the same), if my DT880 kicked the bucket today, I would re-purchase the 600ohm DT880 manufaktur just for the psychological satisfaction of knowing I had the sweet "audiophile" model. 

 

That's what alot of this stuff is anyways - psychological satisfaction and a major cause of upgraditis.

*shrug* well, when the price is about the same, ya know? But at least I know not to refuse if someone offers me a cheap DT880 250ohm.

LOL.........  are you sure you'd do that?  Spend the money on the "Audiophile Model"  for psychological reasons?

 

Question:  Are you using a special audiophile power cord?

That is exactly what society is all about -- spending the extra money for psychological reasons.

Its not like the 600 ohm has the 1000% plus mark up you see on that kind of crap.

hi guys... this has been an invaluable thread. thanks to the OP.

 

I would like to know the science behind properly powering the 600s tho... I have a totally 'stock' build M3 and am concerned it wont power the 600s to full potentional...

 

some say it will and that morsel designed it for 600s others say the output impedence ought be b/w 2-4x phones impedience?

 

how would one measure that? IIRC the output impedence on an m3 is near zero...

 

any other amp specs one ought pursue? I wonder if the majority of 250s out there would be better powered than their 600 brothers....

You're a fool to think you're immune to auto-suggestion.

 

If you would check carefully, he is the starter of this thread who has been very logical and rational in the face of great douchebaggery.

 

Props to you Catharsis for being so cool throughout, and being able to find an answer. I also like your name.

Unless you're looking to colour the sound, an output impedance close to zero is ideal.  There are a few head-fiers around here who can calculate the voltage requirements for the 600ohm DT880 (I can calculate current, but that should'nt be an issue).  In most cases, if your amp is plugged into a wall and you're getting 16V or whatnot, you should be absolutely fine, although I would love to have some of those calculator guys show up to ensure what I'm saying is true.  For portables, I'm not sure if a 9V battery would be enough (2x9V = 0kay)

Wow - thank you Trysaeder for your kind words. 

 

The support from people such as yourself has been overwhelming in this thread, and I wish I had the time to thank all of you by name.  When I started this thread I put my war-helmet on expecting an epic battle, but it appears as though only a few opponents showed up on fighting day. 

 

Thank you so much everyone for your awesome contributions to this thread.

the specs on the 250 indicate a sensitivity of 96dB - i'm assuming at 1mW.  a 600ohm impedance will require a little more gain voltage swing than the lesser impedance varieties, but this isn't a significant amount considering we're driving sensitive HPs.  looking at the M3 specs ( http://www.amb.org/audio/mmm/  ), assuming you have a o11 at 27V, Wmax with the AD8610 will be 2Wrms into an 8ohm load.  driving a higher impedance HP will be easier, requiring less current.

 

assuming your source puts out 2Vrms and with an impedance of 600ohms, and assuming no current limiting, Ohms Law says max current draw of the HPs to be 3.3mA, or 6.6mW.  you need 1mW to reach 96dB.  you will have no issue driving the 600ohm.

 

the default gain setting for the M3 is x11 because Morsel used the 600ohm DT990, requiring a little more voltage swing to give you more play in the middle-range on the volume pot.   

 

btw, i loved the M3/DT990-600 combo.

Agreed completely.  That power cord was something...... !!!! 

 

Amazon has the 600 ohm version for $249.99 and the 250 ohm version for $248.85.

 

With no premium to pay, which model would you get and why? 

 

USG

 

PS:  I'm wondering who actually said the 600 ohm version was the audiophile model besides the fanboys who got sucked into Beyer's original marketing hype, like the guy who bought that power cord?
