It could very well have more power, since it has higher power supply voltage, and the NJM4556 op amps in the O2 also limit the maximum output current. However, if you do not use a Hifiman HE-6, then the O2 likely has enough power anyway.

There seem to be no updates, the designer was not active on his blog for almost half a year, and is apparently very busy and has no time for the O2/ODAC/ODA. At the moment, it is probably better to get the O2 with a custom DIY enclosure if you want a more "desktop friendly" form factor, than to wait for the ODA, which may be released only after a long time, or perhaps not at all.

Regarding power: most headphones only need a fraction of a single milliwatt to reach 85 dB SPL.

 

In case of the DT990-600 ohm thats less than 0.3 V.

 I dont care how it looks...its how it sounds.....looks are important to some extent...but the sonics are way more important....

 

I did buy a uncased ODAC and installed it in a box that matches the O2 case...and with the rubber feet mates nicely...I will post pix later from home...

 

I also added RCA jacks to it as well so I can use it in my 2 ch setupif desired...

 

Dont hold your breath for the ODA....you can DIY one that has most of what it will/would have had....which I did.

 

All the best

In the spirit of open source which is attributed to this project, maybe it's time to see if the designer will release any schematics he has for a prototype and let the community--if there is anyone willing--finish up the design from here. Not to mention there are few vendors globally making money off the O2 and ODAC. It would seem in their interest to come together and promote such an effort.

So...does anyone actually THINK they hear a difference between the O2 and Magni?

 

Does anyone with both prefer one over the other and not due to features and specifications on paper?

 

Wondering if the O2 is worth bothering with if I have the Magni.

 

My guess is that I will find it to be exactly the same or better.

 

Has anyone tried the Q701 with both?

 

It's also interesting that both are labeled as "cold and analytical" or bright. Bright? If it's really transparent, is that possible? Must be only bright sounding due to a bad recording..

 

Strange, I no longer find the Magni bright at all. Even with my Q701.

 

I want a Magni that's about 2% warmer sounding normal_smile%20.gif So about 99.999% transparent

 

EQ is too painful. Don't make me do it..

 

Oh yeah.. I can also make my Magni very warm or thin and harsh. Just need to find the correct track biggrin.gif Yeah, it's that accurate I guess and won't change the recording. Not that I can tell.

On some tracks you can get bloated bass on the Magni too. Amazing how many tracks have such bloated bass IN the recording.

 

Sorry..just been trying to figure this Magni out. It reminds of a lot of my Micro Amp.

Sounds like you might need a tube amp as an alternative to the Magni smily_headphones1.gif

Mac vs PC anyone?

Just kidding.

 

Really?

 

I think the Stack is kind-of meh... farther away it looks pretty nice, but the LEDs are very bright. Up close, it's obvious that the chassis is just cheap painted steel. I have a JDS alu front panel and a blank alu front panel for the O2 - the JDS one has some poor text but the blank one looks nice compared to the Stack, IMO.

 

All opinion, of course.

MIA for a few months. "Extended time away." JDS blogged 4 months ago (almost exactly) that they don't know.

Not sure if anyone's mentioned it here, but wouldn't it help to keep the power supply transformers away from the audio equipment? EMI issues and all? Op-Amps have a certain amount of rejection, but why take a chance?

post #280 of 424

Lots of head amps have ac transformers inside of the box, some have external pwr supplies etc...

 

I think the ODA would have an external AC Adapter....

I have a question slightly out of subject.

 

I will buy a O2+ODac (all-in-one) and I am wondering how i could plug it to my media player (WD TV Live Hub). The only place digital audio comes out on the media player is from the optical output.

 

Thanks.

 

EDIT: Also, is there a USB input on the "All-in-one" O2+ODac, i have looked at pictures and it just looks like a O2, how can it go through the Dac if there is no USB?

I don't know anything about optical out stuff, yet.

 

As for USB, there's a mini-USB input in the back of the O2+ODAC.

As MiceBlue points out, the USB input jack is on the back panel of the ODAC+O2 combo.

 

Since that USB port is the ODAC's only input, you'll need an S/PDIF to USB converter if you want to connect a WDTV box to it. I don't know anything about these.

So as the current owner of an O2 with no ODAC, would I be right to say getting a Magni would be a waste of time? I was wondering how mixing and matching would work. I don't have a standalone DAC. It's simply awkward to have my E17 on the floor in a mess of cables the way it is now. The modi does seem tempting for the price.

Unless the Magni has some feature you find lacking on the O2, you're simply buying another amp.

 

It's possible to mount an ODAC, with some circuit mods, in the same case with a standard O2. The Schiit Modi and Magni have nicely matched if not integrated cases. But, electrically and sonically, mixing and matching will work just fine.
