First one is banana, it's use for amplifier to speaker. ( cannot be used)
Second one yes, RCA to 3.5mm converter.

the power is very low, only 5V drawing from USB. So, nothing really need to care about.

yeap, let it on 24/7

I assume you shouldn't let it sit on metallic/conducive surface.

Potential short circuit

Technically you just see the LED does not light up.

Seem like my china labour is leak my design out?!
No copyright for my pcb !

*Will discuss it later with the china labour these few days!!

Ya, inside all china imitated products.

@@, i don't have any register domain to do so. So
i am failed.

Few updates from now:
*All wm8501 will stop selling start from now,
*Next china labour changed,
*Next DAC to be design is target on DACPORT +/-equality sound.
*PCM2706>ak4396> OPA1612
*Remove RCA output
*remove spdif output
*selling price lower than wm8501
*100% Copyrighted.

The prices are not much different if u calculate the shipping fee together. But then..the original designer problem, is big deal.

I'm curious to know too.

the story is simple

I design and draw the PCB, send to china labour for PCB printing and soldering jobs.
Send back to me and i resell.

Story goes bad, he himself print and solder the pcb and sell to out source without
my permission me. 
The +/-sound of DACPort, imagine it. 

chronologically speaking, chchyong89 is 'in the right side' since he posted the pics first.

I am very sarcastic and selfish man. That i only want to sell something
that can't find at other places.
PM me, as long as I am alive! I would like to serve all of my
buyers!

A definition of the word hypothetical is "not well supported by available evidence".
but you yourself was the one who came up with the evidence ie "...but only 1 thing i can c is the date of posting the photos are dif.
u posted on Dec 19 2010, 12:46 AM
but hifimediy posted on January 17, 2011" so I'm like kinda confused.

plunderer1 is making an assumption and very cleverly tries to avoid responsibility for his own words by adding 2 question marks at the end to make it look like a question, here "i think its not done by chchyong89, so means that it will copy from others somemore or DIY by heself ??" And you have come out in support of an assumption.

Let's not jump to conclusions nor make assumptions. If you are happy with what you have bought maybe it's time to move on. And if you are not happy with the item in question or the circumstances surrounding this issue you could always PM chchyong89 to try and work something out. I can see some of you are hell bent on some sort of mud slinging. DON'T! It does nobody any good and just leaves a bad taste in everyone's mouth.

No bad feelings all of you, I would not giving myself any excuse,
I would admit to say that is my fault because I made the products
without putting effort on considerations and survey on PCB factories/labors
choosing and marketing.

So this product will officially stop selling from me, any of the
technical support for this DAC can PM me, as long as i am alive. 

i trust chchyong.. because he is cyber mmu !! i am too.. i trust our msia student did that... !!

What if 2 version leh? Casing and non casing version 

But sure i will choose the casing version +1

Find leg from the yellow cap, solder a 0.01uf non polar capacitor in parallel with it, be sure to keep the 0.01uf leg very very short.
