That's not good. Are any of the pins broken? If so, email Kingwa at Audio-gd to have a new one sent to you. If the pins are bent, you can use a mechanical pencil to straighten the pins. I used one to straighten the bent pins on my Earth HDAM of the bagged Compass I received and it worked well.

Yea, the pins were bent. I straightened them out and popped it back in. Just hooked it up and thankfully it sounds fine. Good thing nothing was knocked loose or broke from that. Only casualty is that the OPA was ripped loose from the ground wire. Not sure if I'll notice a difference or not from that.

They are all large companies with a huge budget. It's quite a big deal for a tiny company to offer this, IMO.



Did you know there was a gain switch on the back? I should really take the shovel to you guys, since I discussed with grawk about my writing FAQs, yet it didn't appear anyone who was in the discussion read the contents of them.

Some history: All the Audio-gd headamps had cheap, Chinese locking jacks on them, which were easy to release headphones from, but also poor as the sound would drop out often from a bad connection. Since locking jacks are supposed to help maintain a good connection, this was rather stupid. I basically said to Kingwa, never let any headphone amp out of your company ever again with those cheap jacks, as no matter how good the design, it will all be for nothing if people complain about the signal dropping out from those cheap jacks. He replaced them with the genuine Neutriks instead. I agree they are probably unnecessary.





I have no problem with the Neutrik jack on my Compass, in fact I think it's cool looking and I don't care that I have to press the thing to release the connector ... big F'n whoop, ya know ????

That's good...I'm glad it's working for you. I am using the Sun v2 HDAM and don't have the ground wire connected. I think it sounds better without it.

This is the way I feel as well. I always leave my headphones either not plugged in or out of the way when I'm plugged into the Compass so tripping over cords and sending it flying isn't a serious concern right now!

Well, that's a first. Strange things happen during transport indeed. I would never thought it could come loose during shipping since it's basically wedged tightly in the case. Was the foam (foamtape) that's supposed to hold it in its socket still in place?

Glad it still works though. The ground wire probably doesn't make a world of difference. Still, if you happen to have a soldering iron lying around you could try reattaching it.

Is it not dangerous for the HDAM to not have the ground attached? I would have worried about it frying the little guy!

Here is what Audio GD website says :

Quote:

Even if the earth wire is not connected or used, the output sound will have slight difference. The user can choose to decide on his own, but we recommend to connect the earth wire to ground. Please do not connect OPAs earth wire to AC power socket ground.

Hmm, very interesting! I just assumed that the ground would work like other grounds: to protect from surge damage, etc. so unplugging it just sounded like trouble. Now I may have to give it a shot, thanks!

I hope to get the DAC100 for audition by next week, and to compare it with the Franken mod. however, zero with franken mod is still much cheaper than the DAC100.



I think they no longer sell the dac100 already

dac200 is their entry model

Why did 3 accounts all say the same thing?

"This one is also mostly great.ya rally?

Someone setting up multiple accounts for HF-2s?

They are all spammers. They have an image link in their signature that doesn't show. I've reported them.

Not looking to start a DIY discussion in this thread.

My guess: Metallized Polypropylene 700pF? (but seems like an odd number)
I could be way off. Any ideas?

For the record I found out that these caps are silver mica 7pF. No need to change these if you want to cap mod the compass.

Oh my. I recieved my Compass today. The post office actually attempted to deliver it yesterday, but I was not home. Started shipping on June 1st, arrived to Superior, Wisconsin on June 4th. Pretty fast EMS. Out of the box with my girlfriend's HD555s this sounds amazing. More impressions when burn in is complete and I have my HD650s!
