In the mean time 3 eneloops in series do their job just fine:)

 

1A is more than enough. Computer USB ports output 0.5A normally.

 

Good point; BTW I'm discussing this same thing on another forum and this link was posted: http://www.circuitsathome.com/adum4160-usb-isolator-assembly-guide

 

I'll try that circuit isolator first; if it proves noisy I'll go with the Eneloops.

The O2 powers the Q701, K701, and K702 with room to spare. Who misled you to believe otherwise?

You should say that you don't like the pairing . Rather than "can't power " .

Do you find the O2 produces a thin, flat sound, possibly with harsh treble and a lack of bass?

Thin and flat... Absolutely! The O2 has very low noise (thin) and is linear over the entire audible frequency range (flat). In virtue of it having a flat response, you may find it lacks bass in comparison to your other amps, but that is only because your other amps are not flat (they emphesize bass). Treble is not harsh, it is clean (low noise) and accurate (linear).

 

If you dislike the O2, then what you really dislike is your headphones!

Not I! I was trying to draw out the other poster and then reach the conclusions you posted.

 

There are some Classical vocal passages (strong, loud, Sopranos) which are piercing with the O2 and JVC HA-S500. With the O2 and HD-650 or DT 990, they're sublime. With the M-Stage and S500, they still sound good. Logically, that's similar to what I expected.

 

But, as they say, the proof of the pudding is in the tasting. To me, the ODAC+O2 combo tastes good.

Thinking the O2 sounds thin and bright with the AKG phones and concluding that it's not powering it.  Good ol' head-fi.

post #1180 of 1938

The O2 does not lack bass.

 

My LCD2's are awesome with the O2 and ODAC, My AKG 702 and Q701 play very well...and the O2 has no issue driving the 701/2 to levels louder than you can stand.

 

The lack of bass is more the cans ability to reproduce bass...

well, assuming i got the m stage for practically the same price as the o2, which is a better value?

 

The matrix has 4 gain settings, does the 02?

The matrix has 2 rca inputs, what about the 02?

 

...i'm not knocking the O2, i''m, honestly curious. 

 

And assuming the ODAC pairs well with both, can anyone  recommend anything better, DAC wise?

 

How does this compare to a hrt msii

The O2 has two gain settings, one analog input, and uses two, 9V, rechargeable batteries for portability. It's more transparent (but not by a large margin to my ears.)

 

The ODAC and HRT MS II are indistinguishable in sound quality. The MS II accepts a wider range of input encodings and comes in a more compact package.

 

The ODAC+O2 combo has one USB and one analog input. It requires an external, A/C transformer.

 

Which is a better value? That judgement is for the eyes and ears of the purchaser.

post #1183 of 1938

Never had a Matrix....and dont know how it actually measures up to it spec wise...but its a discrete amp i believe...lots to go wrong if its not done correctly.

Many folks have them and like them...

 

I have had the HRT MSii and the HRT MSii+....both good USB dacs...

The ODAC is as good...name your poison.

For the price the ODAC is a very good perfroming dac...

 

The gain issues is not a real issue for me....you want to use the lowest gain setting as possible.

You can change the gain settings in the O2 depending on you needs..its all well documented on the blog over there at the designers site.

 

The amp i built and the one i got from JDS Labs uses the standard gain and I use the lower gain setting with multiple cans...no issues.

 

Good Luck

Just bought the ODAC from Head 'n' HiFi after reading your comments (thanks btw).

If anyone is interested I'll post my impressions on any improvements/drawbacks in sound quality compared to my Asus xonar essence ST soundcard.

post #1185 of 1938

Ok, thanks guys. That's very helpful. I'm quite excited to get the matrix. And now that i know that the odac and hrt msII are the same in terms of audio quality, it makes my life easier finding a deal.
