That's okay too - say between 9:00 and 3:00...

Hi All.
I get Move.
It bought it from a Japanese agency of Meier. (I'm Japanese)
It aesthetically likes the sound of MOVE.

It meets two troubles.
Eyes are that 006P battery becomes a loose connection one.
006P battery of Panasonic moves internally. It is not possible to fix.
It is the same also in the battery of the GP Co..

The second is a shake of the plug.
The plug shakes, and the noise has occurred.

When commuting due to these two troubles, it is not possible to carry.

Then, E-mail was put out to the Meier Co..
There was an answer from Mr. Meier.

According to Mr. Meier

The battery has the difference by the manufacturer in the size.
It is understood not to fix with MOVE well. It was recommended to correspond with the
spacer.

As for the shake of the plug, it was an answer that was not able to be agreed.
It is said that it is an individual difference though it is a shake
not seen in other PHA.

Other users (in Japan) are in the same trouble, too.
There is dissatisfaction in this quality of conformance though it likes sound
of MOVE.

Dr. Meier is very right about this. There's no real size standard for 9v batteries at all. Some are shorter and thicker, or longer and flatter, or, or, or.....

But this is pretty easy to fix. You just have to put something behind the backplate that will fix the battery to its place. I have to do this with my Hornet as well when using a certain brand of rechargables.
Isn't there even a strip of rubber that comes with the Move for that very purpose? (It might be the spacer you refered to...)

What do you mean by shake? Is it a loose plug?

A few others have mentioned these issues also...

Here are some of the biggest complaints about the move:

thx manox2
It is animation and an understanding shake of.
I also want Mr. Meier to recognize the problem.

High Current (9 or 12 Volts) and Low gain (the jumper inside the amp) ?

See what your ears tell you...
I also have 595's and agree with the high current, low gain settings. I find quite a noticeable difference between USB power and either the 9V battery or a 12 V adapter. I found a RadioShack adapter that is regulated at 12 V (at least in my experiences).

Yes, very loose!
If the noise doesn't occur, it doesn't do to the problem.
The noise has occurred because the plug is loose.

Question to all PK1 users: what gain and what current to be set on with a 9v battery for the best SQ?

Thanks!

High current. Your battery will drain faster but you'll have a better performing amplifier.


Gain is dependent on the efficiency of the headphones. HPs that are easy to drive (highly efficient) use low gain so you have more room to adjust the volume knob. High gain on high efficiency headphones causes the amp to deliver very loud sound at low volume settings.

I run high gain high current with UM2's...small volume knob travel, but impeccable sound....

Like I posted before, I couldn't get rid of it except when I added an external powered USB hub. While feeding the Move from my desktop (or laptop) the hiss was too annoying.

But now it is gone and I'm pleased.

Cheers!
Nothing fixed it in my setups (pretty loaded Asus P5ND2-SLI sytem and HP laptop) except trying an external powered hub. Befored that I always got some hiss and noisy silence even in low gain mode. This was more obvious with the Mylar X3 and less intrusive with higher impedance headphones.

I do not know if that has anything to do with the Move's build quality but the issue disappeared when I used the hub. Now silence is pretty dark and flat as it should be.

I have also tried the Corda Move with a different Toshiba laptop and there was no hiss at all using the same headphones so this is probalby related to the source's DAC and USB power line.

Overall, despite the external hub need, the Move has been a great product. I'm happy with it.

I get zero hiss from my Apple Mini, HP pavilion dv8130, or IBM T41.

Yesterday I tried plugging the MOVE into my AV710 (black Alt. out) via the cable that came with the MOVE.

As of that moment, I was brought closer to the sound, the sound was cleaner, and there was even more impact.

Anyone with an internal sound card with some snot may wish to try this. To my admittedly inexperienced ears, I think the AV710's Wolfson WM8728 DAC (which I use as described in this thread) sounds better than the Texas Instruments PCM2704 in the MOVE.

Yup... it's a DAC off:

Wolfson WM8728
SNR: 106dB
Sample rates: 8kHz-192kHz
24-bit PCM
Data sheet source:
http://www.wolfsonmicro.com/uploads/.../en/WM8728.pdf

Texas Instruments PCM2704
SNR: 98dB
Sample rates: 32KHz, 44.1KHz, 48kHz
16-bit PCM
Data sheet source:
http://pdf1.alldatasheet.com/datashe...613/TI/PCM2704

I'm sure those aren't the only specifications that affect sound quality, but I don't know hardly enough about this technical stuff to comment any further (or even this far). I'd be interested to hear what other people think about the MOVE vs. their dedicated sound card's DAC.
