After burn in about 8 hours since last night.

Now My Onkyo DAP DP 1X and my Ocharaku Donguri sound very good.
My impression after 8 hours is that my Onkyo DP 1X the sound now opens up.
Highs :
Is brighter and clearer too .
Now high has better presentation.
Cymbals sound very clear and clean.
Mids :
Has better pronunce and clear.
Out the box when I first heard the mids they were not so clear as like today.
Bass :
Has better detail and very clean sounding Bass.
Yesterday Bass sounded not so clean like today.
Separation :
Now it is very good .
Yesterday it was not so good.
Soundstage :
Now it is wider and has very good depth.
Yesterday was so narrow .
Black background:
After 6 hours nonstop burn in. It now has a blacker Background.
Overall :
Out the box was really not my cup of tea.
The sound quality was not so clear and congested .
This morning really surprised me.
Overall sounding very clear and clean like My HDP R 10 with Sabre DAC Chip.
I was so frustrated .
Why double DAC chip sound so congested and not so clear.
I am very happy now with Onkyo Dap DP1X.


I would like to share the Onkyo Dap DP X1 out of the box first Impressions.

Thanks Damon -- may I ask some questions first:

1. How honest could we go?

2. Regulation on review unit, free review unit/sample, "free" review unit/sample?
3. What if the review is against the products of site sponsors?

1).Be honest.
2). Be transparent. Say whether you bought, got given or were loaned the unit for review.
3). We have no advertising or sponsors as such, as yet. 


What we are looking for:

Short pieces, medium pieces, long pieces.

Each submission would ideally contain 1-5 photos.

Short announcements about new products.

Impressions of gear that you have tried or that you own.

Short or lengthy review of gear (Daps, amps, headphones, earphones etc).

Comparisons between similar products in the same price range (Daps, headphones, amps etc).

Articles on cables, bit rates, audio shows etc.

Interviews with makers, designers, companies of audio products.


Simple is best, less is more.

*Please see older articles in the blog for some ideas, of course adopt your own unique style.

One audio head friend told me about one prominent member of our community. I mentioned he seemed to like whatever he reviewed - although he didn`t review much.
He replied that he only reviewed what he actually liked. Fair enough.

Sometimes we may review bad products, but usually we will stick to products we like and think are worth our hard earned cash.


*Questions  may be via or via our Head pie Facebook page.

*Submissions may be made to

*We reserve the right to refuse any submissions or request more information or editing.

*We may edit articles for grammar, spelling etc but generally not the content.


We look forward to your participation.

This FAQ will be updated as time goes on.

Kind regards

What i like no coloration.
It is one to one copy.

Compare to PC ripping
The Sq is more natural and has No Coloration.
Better Black Background
With the PC you can adjust the Sound Quality for better Result .
With AK 380 CD Ripper you can not do any improvement on your CD ripping sound Quality.
Sofar i like the CD Ripper Sound Quality.

Last night i have tested my Ak 380 Cradle Balance Out to Mass Ko Bo 394 Fully Balanced Amp.

Ak 380.
Accessories :
Ak 380 Cradle.
Amp :
Mass KoBo 394.
AKG K 7XX Massdrop edition.
Cable :
Home DIY Balance XLR 3 PIn.
Sound Quality :
So far my Best Dap as Source for Mass KoBo 394.
This Sound Quality is near the SQ my CD Player April Music CDA 500.
I guess this Cradle uses USB as Power. Thats why the Sq so full .
It is useful and recommended for AK 380 Users.
Note :
Sorry for the messy Pictures , because the Balance Cables XLR 3 Pin are very Stiff.

How do you store your gear when traveling daily or for a more lengthy time period?

I bought the small green bag today as I was walking past a sale. Perfect size for my ipod touch 6G 128GB, Cozoy Aegis and ATH-CK10.

The red back is a small camera bag.

Often posts and threads pop up on Facebook and various audio based forums asking about where to go when looking for audio gear in Tokyo.

I will list a few of the more popular ones.

Over time I will will add more details and maps etc.

Already on the head pie blog there are two posts, one for Fujiya Avic and one for Bic camera.

Lets start with the large department stores.

These are Bic camera and Yodobashi camera. Not a lot separates these two places.
As you will see on my post on Bic camera in Shinjuku (West side) the headphones, dac/amps etc are all laid out on display with samples you can try easily by yourself without the need for staff.
Just bring your own dap/source to sample the headphones, headphones and source to try the dac/amps.

Not every Yodobashi or Bic camera has a large audio section.


Fujiya Avic in Nakano. (3F Nakano sun mall).

This is situated in what could be termed a mall, although not in the general sense of the word. It is quite old and the mall is populated but niche shops of all kinds, toys, anime, antiques etc. Its the kind of place people are looking for when they visit over developed and sanitized Akihabara these days.
They have a small shop, but a wide range of portable in ears, IEMs, multi driver IEMs, over the ears headphones, cables, daps of all kinds, dac/amps. They have most of the popular portable audiophile brands.
They also sell new and used, the used products in Japan are often as new.
Most gear except for earphones are locked away and you will have to ask the staff to try out the various gear. Older staff.

*Photos and maps can be found via google of course ;)

DAR`s useful post


e-earphone. This is in Akihabara and can be hard for some people to find. They now have a shop downstairs for getting your ear molds for custom in ears so its a bit more visible. I do recommend doing some research about where it is to avoid frustration. (I plan to add a map in the future).
Lots of headphones and dac/amps, amps laid out to try by yourself. Some items such as Daps and sources are in glass cases and you will have to ask staff to assist you.
Its not a big shop but like Fujiya Avic it has most of what you may want n a small space. Young staff.

*Photos and maps can be found via google of course.

Great post by DAR
