Your Magni died? :o

I guess Schiit products will be Schiit. *generalising of course, I have no direct experience with Schiit's customer service and I haven't been too impressed with their products*

Yeah. I switched my Magni off before I went to bed the night I got it, woke up the following morning, flipped the switch, nothing happened. Checked the wall wart, nothing was wrong with it but the Schiit was dead. Seeing as this is the first Schiit product I've ever bought, the Magni was not the greatest of first impressions.

 

Currently waffling back and forth on whether or not I should simply return the things and take a $60 hit (due to shipping and restocking fees) or try to exchange the Magni and sell the M/M combo (the Modi still works, after all) to someone on Head-Fi. Decisions, decisions.

 

In the meantime, at least I have the O2+ODAC to keep me company! beyersmile.png

Gosh sounds like a quality control issue there?

 

All of the Schiit stuff I have had, Asgard, Lyr worked flawlessly regardless of its sonic qualities....and Jason has always been top notch in contacting me with any questions...

In Canada the most they can charge you is sales tax on electronics. There are no duties on electronics for personal use.

Holy mackerel this is depressing.

 

So before I left the house for lunch/grocery shopping, I was doing some headphone testing between my earphones (Sennheiser CX 300 and MEElectronics M9). I come back home 2 hours later and my O2 is dead. To make sure it's my O2, I plugged it into my Clip Zip and I get no sound. Gain on or off, battery-powered or not, headphones or earphones, my O2 doesn't make any sound.

 

My ODAC works just fine. At the moment I have my earphones plugged-in to that even though it's just a DAC.

 

What to do? :(

I'm sure "he" will post an update sometime or another. He's gotta be almost finished with the ODA schematics by now. Or not.

Well then, apparently my AC adaptor is dead. John suggested swapping out the batteries and the O2 seems to be working again.

That wouldn't be so surprising. there aren't many AC-AC adaptors out there and the ones there are do seem to be on the cheaper side. I have both a custom german one commissioned in one of the diyaudio groupbuys (it was expensive), and an ebay one at a quarter the price. The ebay adaptor is, what shall we say, rather too eastern oriental? smily_headphones1.gif

The german one is built like a panzer!!!! I'll never sell it. Respect for our German brothers. smily_headphones1.gif I don't think I'll be needing that ODA power.

The O2 I built myself with leaded eutectic solder, which means it is more reliable, less breakable (from dropping) and probably won't develop a solder fault in future, unlike new unleaded solder. The ODAC is US made, as we all know, so at least it has that going for it: quality build and parts albeit unleaded solder. I'm nicely set up. I regret not building with the B003 case + 1/4 socket and RCAs. It turns out that the 1/8 (3.5mm) sockets are rated for 2000 insertions. frown.gif

So now I am using a short belkin 3.5mm lead to avoid those insertions.

I've used unleaded solder for electrical lab classes, and yes it's not very good. XD

I'm not 100% sure if JDS Labs uses unleaded solder on the other hand. As an audio company, I would think they would know better than to use unleaded. At home I have some 62/36/2 solder.

Well, I'm not sure of the US situation but any commercial electronics sold in to the EU has to use unleaded. Much of US produced goods are already made with unleaded. JDS likely uses leaded but the power supply is probably unleaded.

I can't help wondering why people always ask this. Build one in a larger case with a 1/4" socket and RCA inputs and you have an ODA. smile.gif

Here are some of the advantages with ODA, not only RCA inputs and 1/4" socket. 
 
(CTRL+C & CTRL+V from Guy site)
 
Real Ground – The ODA will not have third channel masquerading as a virtual ground to mess up the performance. It uses a proper bipolar power supply referenced to true ground and direct coupled outputs.
 
Higher Quality Power Supply – The half-wave power supply in the O2 is something of a compromise for size, cost, and battery charging reasons. The ODA power supply improves on the O2’s in several ways.
 
Wider Source Compatibility – The ODA should work with anything from an iPod Line Out Dock (LOD) to high output home DACs with a wide range of headphones. It has more flexible gain options compared to the O2.
 
Headphone Protection Relay – The O2, like many amps, produces a “click” in the headphones when you turn it on and a soft “thump” when you turn it off. The ODA uses a headphone relay to eliminate these noises and provide added protection for expensive headphones.
 
Other Possible Upgrades – Depending on how the details sort out, the ODA may have some other upgrades as well such as a possible preamp/line output
 
Happy listening! 700

The ODA as mentioned in the post above is a little different thab the O2, no batteries was one of the design points etc...so no portability. Thats ok with me.

 

Sonically it seems that it should not be any better or any worse than the existing O2.
