Well that escalated quickly.

My bet is the MSII is your problem, to high an output into the O2, get the ODAC, or you need to lower the source volume.

I did lower the source volume but I think I need the wall wart improvement. It's thin sound combined with clipping that was problematic. If the wall wart takes care of the clipping and I run it with the HD650 -which demands less power and has been demonstrated to work with the O2 - I should get better results, shouldn't I? Even with a hot source.

Yes power supply could be the problem, not getting enough power, I used the O2 with HE-6 fine but from a iPod line out

Powering an HE-6 with an O2 strains credibility seeing as these are legendarily demanding headphones.  I guess I'd have to hear your set-up.  I guess stranger things have happened.  I read you using the HE-6 with the O2 earlier in the thread and figured you must have mis-typed.

Why? Planar magnetics are almost purely resistive. The only difference with the HE-6 is the low sensitivity / inefficiency.

You won't be able to blow your brains out with an O2..

The O2 will power the 500's aplumb.

 

From: http://www.techpowerup.com/reviews/JDSLabs/O2_ODAC/3.html

 

The test unit JDSLabs so kindly sent to us was setup with the stock gain of 2.5x and 6.5x, which should fit both low and high efficiency headphones. If you plan on using it solely with in-ears, you might want to set the gain set to 1x and 2.5x. To put it into perspective: this little amp has more than enough power to get the HiFiMAN HE-500s singing at 2.5x gain, and even the notoriously hard to drive HE-6s had plenty of volume available on the 2.5x gain setting.

 

There are tons of posts from people using the 500's and the O2 and working very well.

 

I use (2) Odacs and a MSii+....I cant tell the difference between the 2 except for the 2.25 volts out of the MSii+....both awesome dacs and work well.

 

Remember this is a "low cost DIY" amp  that was designed to prove a point....that great performance and neutrality does not have to come at great cost....

 

If you honestly dont like it fine....then move on to other amps  and dacs to your "objective" liking...

 

all the best

I just got my O2.  Absolutely killer!  I also have a C&C BH and as good as that amp sounds it just can't squeeze the sound out of my DT770 Pro's.  It will drive them fine, but the O2 just gives it that special sound.  Before getting the O2 I was going to get rid of the 770's.  Not now!

Isnt it nice to have a totally transparent neutral device that can finally allow you to hear what your cans really "sound" like.

I enjoy reading about more happy owners of the O2, it's still my reference amp, and nothing's beaten it yet!
