Audio-gd Phoenix balanced headphone amp. - Page 137

*Double post*

Sorry guys!

However, where are those rubber feet? I don't see them in the box or on the feet of the amp. I'm using little pieces of paper to seperate both units. Is that a good idea?
Were should I plug the data cable coming from the power box? Left or right? I plugged in the right one. Does it make a difference?

Sounds like what's called "zipper noise." It happens because the volume transitions are made when the signal level is above zero. More sophisticated digital volume controls avoid this by using what's called "zero crossing detection." In such circuits, the signal is sensed and the volume transition is only made when the signal is at the zero point.

If the Phoenix doesn't use zero crossing detection, then the zipper noise is "normal."

Debug button in the back will reset the volume from 70 to 90. I think the clicking when you change the volume is quite normal. I believe it happens with balanced output also.

W T F ?!?!?!

Those clicking sounds are very obvious and why the fakk am I hearing a distortion everytime I incease or decrese the volume in my cans and speakers? This is abnormal for a 1200$ amp.
I paid less for the Compass and I didn't get those fakkin' annoying distortion sounds and clicking poping sounds when I played with the volume knob.
This is pissing me the fakk off! I paid 120$ to have this thing shipped and I waited for all the bugs to be reported and fixed and I get a faulty amp.
Oh by the way! The 99 mode doesn't work at all, at least I hear no sound in single ended mode. All I see on the screen is oN 99 and when I play with the volume or selector wheel, I see either 00, 70, 99 or oF.
WTF?!?!?!

I don't hear distortion, so that's something else.

I hear occasional clicks when I increase the volume too fast in either direction. Not now when left alone.

I don't know whether you have a fault unit or not. But, please restraint from using "fakk' please.

Okay! I just figured out how the debug button works with 70/99 and oN, oF modes.
And I still hear those anoying distortion sounds and they get louder as I increase the volume.

Just curious.

Are you getting the clicks when you change volume when no music is playing or if you have no source connected to the Phoenix?

k

I only get the clicking popping sounds when the Phoenix is turned on and when I turn the volume left or right between 0-70 or 0-99. Before 0 and after 70 or 99 I don't hear them. I don't need to have some music playing or my DAC feeding the Phoenix to hear the popping/clicking sounds.

Thanks.

If you're getting it with no music playing or even without a source connected to the unit, then it's not typical zipper noise and there's something wrong. Either an inherent design flaw, something wasn't adjusted properly before it shipped, or it's broke.

This is pissing me the hell off!
I just emailed Kingwa. I explained him everything and I asked him if he tested it personnaly before shipping it. I'll wait for his reply.
I'm a student on loans that shouldn't have bought this amp in the first place and I don't have the dough to send it back.
Thanks for helping out Koyaan. Btw, Koyaanisqatsi is my favourite Glass composition.
I'll report back tomorow morning. G'nite!

I'm sorry to hear that. The more I hear stories like this the more I'm convinced that sadly Kingwa's just not ready for prime time.

You're welcome. Wish I had some better answers for you.

And I like it too, though I can really only listen to it when accompanied by the film.

Okie doke. G'night!

Now I'm just scared as fudge for the Phoenix coming Monday. This is BS, how does he not hear these things at the factory.

The minor clicking when you change volume is normal with this amp. It seems to be random and doesn't happen with every click of the wheel. It is extremely minor on my amp and hardly noticeable.... certainly there is no distortion involved at all. It sounds like yours unit may have a more serious problem. Discuss it with Kingwa. He is very good about taking care of these things and will make sure you are satisfied. Yes, I understand your frustration. The units need to be more thoroughly tested before they go out and quality control needs to be improved.

I feel your pain, brotha'. I had a defective Ref1. I'm waiting for the new one to be shipped to me.

I have decided to help Kingwa free of charge re-type his website in proper English. It will be a long and tedious process and he really doesn't want me troubling myself but I'd like to help him out with it. I'm almost completely done with the Phoenix page. He would, however like a Phoenix F.A.Q. page, so it would be good if you guys can send me e-mails (yes e-mails, not PMs, to pjnuckingfuts@yahoo.com) with any F.A.Q. Questions you think should be on the list.
