I got the confirmation from Paypal that the payment went through, and the money was taken out of my account, but I still have no confirmation from iBasso. Should I be worried? I was pretty excited too, since this is my first headphone amp purchase.


I wouldn't worry.
I ordered on Sun. , got a tracking # Tues. amp on Thurs.

Send them an email and send them a message via their website and you should get a response.

No reason to worry. I ordered my amp on Wednesday evening and received them on Friday afternoon. Lightning quick delivery speeds! Though I am located in Singapore which is comparatively closer to China than the USA.

I copied emails to service@iBasso and sales@iBasso as well as via their website before gatting a reply.

I don't think they reply until they ship.

I am trying to roll opamps and have trouble discerning dual and single opamps, and where should I put the opamps in which holes? How do I see which ones are duals and singles?

The instructional sheet provides some information but it is not as detailed as I would like, being a complete noob in such things.

May I know if only one dual opamp is required for the LR's or do I have to put two into the single opamp lrs?

Thanks.

Dual opamps go in the middle. if you look at the top picture on the diagram, you'll see it. It took me a while to see it, I usually just read directions; I rarely look at the pictures myself.

My P3 came in yesterday, had some fun trying out some recommended opamp combinations. I'm glad the included so many thumbscrews, so I can use them on the front of the case for easy access. Does anyone know if it is okay to use a regular 12V adapter, or do I have to use the 9V adapter that came with the P3? I don't really want to have so many adapters on the table. And is it okay to gently wiggle the opamps out, or is it better to pull it straight up? The supplied tweezer is pretty lousy, because it slips so easily. Unless I'm not using them correctly...

Don't use a 12v adapter, as some of the included opamps have a max voltage rating of 12v, and most unregulated 12v wall-warts exceed 12v by some amount.

Wal-Mart sells a multi-voltage regulated 1000ma combo power supply for about $15.00 and has many included tips. It works well, and when I checked the voltages, they were exact.

I just noticed on the Ibasso website that:

1) they are temporarily out of Python D3s and;

2) the new T series amplifiers are going to be released soon!


I must have gotten in just in the nick of time, as they told me mine would ship Monday.

Thanks. How do I tell which are dual and single opamps, supposing I am not using the iBasso provided opamps?
Thanks!

Ok I was running the Heron in its stock opamp configuration with the Transister Buffer being used, and encountered a serious problem and was wondering if any other P3 owners experience the same problem.

2930435321_75991c8ef1_b.jpg

I have the P3 in low gain setting, and had my UM2's on with no music playing.

Adjusting the volume pot within the range of the first two dots as shown in the diagram where the red arrow indicates the range of volume pot adjustment, I heard lots of unwanted noise.

I will try to describe it to the best of my ability but have included a direct-download link to the .WMA file which I have tried to record the sound with success by attaching my voice recoreder input to the output of the Heron.

http://rapidshare.com/files/152895478/DS300076.WMA

What I heard was a shrill whistling sound that was never before heard in my Viper. This sound was very persistent and there was lots of white noise also, and only untill I move the volume pot past the second dot, where it would be pitch black and then noisy again, with lots of white noise.

Whilst recording I first turned on the unit with music playing and turned it to the second dot, where I then stopped playing music and turned the knob back down again.

Please let me know if anyone else has been experiencing this and if I should return this to iBasso.

Btw, I have given the P3 a good 24 hour burn in period with the buffers as I thought the problem will go away after that.

Thanks.
