I addressed this iBasso and they do not feel it to be an issue. One of the major capacitors used is out of stock.

I should have gone with D4 instead of D10, I thought I would use Optical out more than I am actually using it and so far D4 is having better feedback.

Its fine, its never too late,try selling your d10 may be you can get 50 percent of what you need to buy the D4, please get the D4 that's when you will become a true portable audiophile

C'mon kunalraiker, praising an amp you own is one thing, but that's just too much. And I'm not saying this just because I didn't buy one before they went out of stock

Well maybe

I'm having a bit of trouble with my new D4.

When I power the amp with 9v power and the original buffers, It starts to oscillate after about 20 seconds. USB and the original buffers works fine. I got the bypass buffers (Hiflight), and they work fine with 9v power.

I was wondering if there are any other buffers I could try?

I have never heard any clipping with my D4.

If I am not wrong, there are 2 upcoming units.

a balanced DAC with (optical,coax,usb) and a balanced portable amp.

My amp isn't clipping, clipping would be in the dac (I think?). Anyways, when I turn the 9v on with the stock buffers, it works for about 20-30 seconds, then starts going to nothing, then full volume and back about once per second.

Putting in the bypass buffers fixed this, but I like the sound of the buffers better.

my d4 works slightly differently from larry (headphoneaddict)'s in terms of the connection:

With USB power from my Macbook, i can use:
1. "AUX">>IEMs to bypass the amp, using only the DAC
2. "headphone">>IEMs to use both DAC and AMP
3. "AUX">>LOD>>IPOD and "headphone">>IEM, i can play from the macbook (much softer), or play from my ipod, or both!

All these without a battery!
