220 mA is not enough for the O2, sorry about that.
 
You could try measuring FETs and power regulators, maybe you'll find the broken piece with ease. Also, might worth trying to see if op-amps are good or not, but I honestly doubt op-amps might break so easy with FETs protection...hmmm...
 
Good luck!

220mA should be enough.
The BOM even suggested a 12vAC 200mA power supply.  That's what I use on the O2s I built, and I've never experienced any explosions .
 
That having been said, I guess it wouldn't hurt to increase his headroom a little bit.  JDS labs uses a 15vAC 500mA supply.  The O2 definitely wouldn't push that supply to its limits.

Hi all,
 
I'm wondering if anyone can tell me the exact name of the usb cable for the O2/ODAC? I want to get something way shorter from the internet and after some research I found that USB Male A to Mini B 5-pin Data Cable would be the size I need?
 
Anyone can confirm that?
 
Thank You all!

If it hasn't changed since the Rev A, the cable you described is correct. This is the cable I bought for when I wanted a shorter one. Its the smallest one I could find (6'') at the time that had a good rep. If you want something longer this monoprice one at 1.5' should do the trick.

Thank you. I am actually looking for something really short, like 10cm. Found this one:

Been thinking to give a shot to these high end usb cables but they all kinda long and there's so much BS going on around them...dunno...
 
If you guys know any mini usb cables around 10 cm (3-4 inches) would be appreiated if you shared on here.

http://o2amp.wikia.com/wiki/Power_Adapters - 200mA is minimum. AFAIK I have 500mA in my O2.
Anyway I wonder why why the transformer got burned and what other components got defective because of this.

Any decent USB cable will do the job. Just maybe add a ferrite choke like I've done as NwAvGuy mentionned that there was some measurable improvement. http://nwavguy.blogspot.ca/2012/04/odac-released.html?showComment=1334803522234#c4272810052548519926

Thank you for all the advices but I just made up my mind right now that instead of spending on aftermarket usb cables I do an upgrade towards another amp/dac and put my O2/ODAC in the classifieds. It breaks my heart to see it go but I have a hunch the upgrade will make me even happier!

It was a nice journey with NWAVGUY in the past 1,5 years, and who knows, I might turn back to it later. Thank You O2/ODAC!!

I'm trying to hook up my O2/ODAC to my home theater's receiver and just use the ODAC line out to the RCA on my receiver. This is in an effort to experiment with some music I have on my PC using the ODAC but with a different amp. Question is, the line-out is 3.5mm...so would I buy something like this to hook it up to the RCA input on the receiver? http://www.amazon.com/Cable-Matters-Plated-3-5mm-Stereo/dp/B00ESM3EIQ/ref=sr_1_4?ie=UTF8&qid=1458580682&sr=8-4&keywords=3.5mm+to+rca
 
The receiver is a Sony STR-K665P if it matters.

 

[raoultrifan]

I believe this cable adapter should work just fine in your setup, in either VIDEO or DVD inputs.

Alchemist007; I use a cable like that to connect my TV's 3.5mm output to my receivers RCA inputs. I also use a cable like that to go from my receiver's RCA outputs to the objective 2's 3.5mm input. Works in both cases.

 

[Alchemist007]

Good to know it's multipurpose.

 

[riverlethe]

Is there any reason to prefer the O2 over the Magni 2 at this point?

 

[Alchemist007]

I've heard someone say that provided enough power, any two solid state amps should sound similar if they're both claiming to be transparent.

Right, so why buy the more expensive and/or uglier one with less features?
