1. 2tigers/red pouch

hi, duly noted.

As an example, don't be worried about leaving a message/post in here but not receiving a specific response (we don't want to keep bumping this thread, it's probably against the board rules)

We will release a spreadsheet so you can check your reservations after we've reached a good number.

Hi. Is there anywhere that I can demo UD125 before deciding?

b. Light Blue

Just to double confirm, can I use it in pure dac mode for my pc speaker S730?

Hi Andre

Yes. The DAC unit is designed to be used as a dual purpose unit. There is a line out mode.

b. dark blue

hi paletteLIFE, unfortunately we do not have resellers or distributors at the moment, so a demo is not possible for now.

We do have some Malaysians with the international models, perhaps if you know some of them you could ask them for a demo.

Thanks.

Thanks for clarifying.

I want one unit then.

Hi, just wondering how to use this with smart phone? Just connect through otg? Do we need external power source? And ak4490 is capable decode up to dsd but it is only 24bit96khz in ud125, what is the reason behind. Just several questions before making order, thanks.

Name: Jasper Lee Teck Zhuen

Pouch: Dark Blue

Our spec guide requires that the Android OTG to minimally have at least 150mA current output.

The UD125 is designed to be extremely powerful, being able to cater to the most sensitive IEMs and very demanding big headphones. We would still suggest you use an external power source by using a splitter to get the maximum benefit from it.

The UD125 is designed around the UAC1.0 standard. If we were to go the DSD route, we would need the UAC2.0 chips which requires very cumbersome drivers. (Kinda defeats the purpose of the UD125)

The UAC2.0 chips will also come at a significantly higher cost. The Ak4490 while is DSD-able, is not budget friendly when designed with DSD in mind. We do believe that the PCM standard is still very robust and high quality, and that the UAC1.0 is more than sufficient for the UD125 class dac/amp.

I just want to enquire if UD125 Special Malaysia Edition has different specification than the previously launched UD125?

Hi Stephen!

It is exactly the same build, with some MOQ-required perks. (such as custom pouch colors and different case design)

EDIT: The difference is mainly aesthetic. This is part of our celebratory effort to return to our roots. (We started off selling at Lowyat Forums)

The international build will remain our staple.

We do, but it's going to be at our usual rate of 6 USD.

Okay. I'll take that.

Would like to ask regarding the filter, how is your personal experience on the filter?
Would you love to use them or remain as it is?

Thanks!

Btw does this work with Pioneer dap?

This post has been edited by dennisbklow: Mar 6 2017, 04:56 PM

We personally prefer the default. keke. The beauty part of it is that you as a user can select whichever sounds best to your ears.

We do not have a Pioneer DAP so unfortunately this is something we are unable to confirm.

Keen on this!

My only concern of the UD125 is it is using Mini USB instead of the currently far more popular Micro USB or the more common printer USB cable, it is not a big deal but I believe it will be easier for user to find replacement cable than the Mini USB cable, it is not a big deal at all but I prefer the Micro USB cable. The volume controller (the toggle) is a little hard to adjust since it is not extrude enough to the outside and my finger is quite big in size, again, it is not a big deal especially when it sell so cheap.

u will fix that or not?

I did purchase this unit via your website, the product quality feel cheap and not user-friendly.

I see, you prefer something more conventional?

Hi salimbest83

The main reason we use the mini USB standard is primarily because considering the timeline this was designed, similarly classed DACs are still on the Mini USB. (and similarly priced action cameras are on it as well)

In our experience as well, the Mini USB is a little more durable than the Micro USB.

There will definitely be changes for the future UD130. We will be putting in more tests to gauge for the best possible USB options in the future.

Don't be worried about the Mini USB cable replacement. The usb cable that is bundled with the UD125 has been proven to be very robust and good. Replacements are plentiful from our side (and at a very cheap price).

As for the VC, the reason why it is mostly flushed with the panel is for durability concerns. It's primarily a trade of between ease of toggling durability.

Thanks for the feedback though. We will be taking all these into consideration for our future iterations.

Hi bsa12.

We're sorry our products did not meet your satisfaction.

Perhaps you could elaborate on the user-friendly part?

there is only one button to control volume and change setting, have to visually check the colour of led light to know the setting change. the model is very light weight and it comes bare unit inside the pouch with no manual.

This post has been edited by bsa12: Mar 10 2017, 09:38 AM

Thank you for your feedback.

The manual is not included because we firmly believe in going the green route.

The manual pdf can be found on our UD125 website:

The exact link to the pdf is as follows:

thanks for the reply.


can i use this purely to replace my computer soundcard.
( USB to UD125 to Speaker/ Headphone )

i mean use it everyday.
is it durable enough to be use that way?

Hi salimbest83

The UD125 is designed for this very purpose!

So the answer to it is yes.

UD130 is coming up soon?

nope.

But considering ESS Sabre just axed some of the chips we use.....*hint*hint*

Cool! Instead of toggle, I think that a button (with colour LED display) for filter selection will be more appreciated. Same goes to volume control. Just my point of view, haven't got in touch with the unit even.

Any info on the exclusive design pattern and what is the changes compare to the conventional version? Is it a complete new design on the shape of the casing or just alter some printing (and color) on the casing?

Name: Makkuri
Pouch colour: Dark Blue

The casing used is the same. There will be a one-time-only design for this case. We will put out more information regarding this soon.

Hi boss,

Am interested but still looking at my budget. Can PM me when this bulk buy is closing along with payment, etc?

Thanks!

Pouch: Red

Looks like it will take some time to complete this preorder.

a. Name (for tracking, any recognizable name is fine): zy_xcup
b. Pouch Colour (Black, Red, Pink, Light Blue, Dark Blue): dark blue

still available right?

updated.

yep, unfortunately that's the downsides of doing bulks these days. We understand that most people would prefer to get ready stocks.

That's why we're pushing hard for a production run that'll include populated units for this bulk.

Certain MOQ related raw materials can be done at a later time.

Wanna add another one.

Total for my order: 2 units.
Pouch Colour: Red, Dark Blue

Any chance I can bypass the amp and purely use the DAC only?
I've been using your previous UD100 and UD120 on my Klipsch speakers and since the speaker is already amped, I'm worried the double amping might be an issue.

What is the closing date for your bulk?

Looking forward to your advise and reply.

Would like to know the description of the different filters in a more layman term.
Is there any word suitable for different filters? Warm? Clear? Vocal?
For example,
None: Neutral
Red: ?
Blue: ?
Purple: ?

Appreciate that

Thanks for your support. Updated.

There's no "double amping" with the UD125.

The design is "quite clever" in the sense that we've managed to integrate both the buffering output stage with the "amplifier".

What we basically did was to use an extremely powerful amplifier to act both as the output Diff to SE Stage and the Amplifier itself. So there's no "double amping" in the traditional sense.

Just push volume button to the max and it'll bypass the internal attenuation and thus becomes a pure line out.

Sorry for the delayed response.

Let's see, as a disclaimer, our philosophy is that while objective measurements can be made in real life, the perception of quality is still very much dependent on the user's experience due to the fact that our ears and ear canals have very different texture and thus the brain perceives sound quite differently. Some filters may sound warm to you but it may in fact sound bright to another.

The AK4490 as we know it contains four different filters, two traditional filters and two modern filters. These filters act as a passband digital "filter" to only theoretically allow frequencies you use to be produced post conversion.

The more "aggressive" the filter, the less frequencies it allows to be produced. You don't want anything that you can't hear as they may be errors or noises. This is why a good digital filter is important for DACs.

However, life is also not that simple, aggressive filters create some other issues by itself, they would often generate new errors by themselves so a delicate balance is required.

These four filter settings are heavily based on the "aggressiveness" of the filters.

NONE - Delay Sharp (Modern)
RED - Short Slow (Modern)
BLUE - Slow (Traditional)
PURPLE - Sharp (Traditional)

In terms of aggressiveness (from most aggressive to most sluggish)

NONE > PURPLE > RED > BLUE

In other words, the more aggressive filters are better at making sure that only audio frequencies are being generated through out.

From a technical stand point, the "modern" filters are better for their intended purposes. Both modern filters theoretically have less errors comparing to their traditional counterparts.

It's really up to you to decide which one fit your particular system the best. For all its worth, we think they are all great and it's even better that you as a user get to decide which one's really for you.

Very well explained. Now I get a better idea. Appreciate that!

So which one u pick sure?
I need someone that understand it to follow

When in doubt, put default
My plan is, to enjoy the default setting first for fairly long hours, then try others in descending aggression order.

However, I still have a question. What colour of light is on when it is at line out mode?
Is D.SHARP (Short Delay Sharp Roll Off) representing the line out mode?

1) Liu Chee Zhen
2) Black

i've been longing for this since forever. let me buy this dac this time pls

anyone tried this before and compared with fiio q1?

Noted.

Thanks. We'll be releasing an excel sheet soon so you can all check your orders.

dont forget me ! i did emailed u before~ nico55orange@gmail.com

No worries We're currently cleaning up the list so we can better publish it so that everyone can double check their placement.




On the other hand guys, if we cannot reach the desired MOQ, we were thinking of going with it either way. However the downside to this is that there will not be an exclusive one time only casing design. We'll still be able to get you guys the pouch colors you want though

Hi would like to inquire:

1. You previously mentioned earlier that you suggest to use an external power source by using a splitter to get the maximum benefit from it, does this apply when listening through a PC/laptop?

2. I have a pair of planar magnetic headphones (Hifiman HE-400i), it has a 35Ω - 93dB SPL/mW spec which seems very low impedance on paper, but I'm told it requires a ton of power to drive them right, specifically more current than voltage.

At a listening volume sample of 120dB SPL it needs 4.19 Vrms (voltage) x 119.71 mA (current) = 500 mW to power them.
I listen at usually no more than 90-115dB which needs about 2.36 Vrms x 67.43 mA = 159 mW (115dB volume).

Will the UD125 at 350mW output be able to drive them well? Sorry, I probably left out some other technical specs, I'm not an electrical engineer and there's hardly any audio gear reviews/sites that explain about how voltage/current work on amps to headphones

Any advice is appreciated.

cheers

BlueDAC from CEtrance, this is so good! It also uses AKM4490, provided with wireless solution.
However, the price is at least four times higher than UD125!

May I know u will be releasing the excelsheets on lowyat forum or fb?

When you use Bluetooth, you no need use dac already. Most of the details are lost in the compression and decompression.

Besides all these crowd funding really know how to play mind games. They will talk until it's really good but end product is usually face palm.

+1

I want to know too.

Sorry for the late reply, it's tax season and the holidays T_T

1. This only applies if you decide to drive it from your supported phones/tablets, otherwise the PC/Laptop will provide more than enough power for the intended use case.
2. Your calculations are correct.
3. It'll be sufficient. You shouldn't listen to music at high volume levels anyway as you'll most likely hit your "ears'" internal clipping.

Sorry for the delay, it'll be done soon.

Wireless is definitely something in our project line ups, though as of current R&D is primarily focused on getting the next high end DAC out.

The thing with wireless is, you're going to trade off some of the more "audiophile-ish" specs that most people want, given what is currently available in the market.

thanks for the reply man, much appreciated. Count me in,

It would be really cool if you could hook up with local designers (industrial/product and graphic designers) to collab the artwork/design language for your future products

I'm a fan of your work, hopefully you can make the Malaysian exclusive graphics happen bro.

List has been updated as of 29/4/2017

Some updates:
1. I'll put up the list tonight before I go to bed, but I'll most likely be removing the email column (for those who identify themselves with your email, hopefully the name is close enough that you know who to look for. This is to protect your privacy to be honest. Also part of the reason why we didn't want to put the list up so early.

2. Raw materials have arrived. We'll push for a production run sometime next week even if we did not reach our bulk numbers. This would ensure that production will still be carried on at a fast pace.

3. Most important point is this, should we not reach the required bulk number by a very soon cutoff date which would be set, we propose that the bulk will still be carried on albeit minus the custom casing. (Need ya'll's input on this, feel free to reply to this thread)

Thanks.

Duly noted.

Thanks for the support bro.

We've added the member checklist here. Please check it out.

https://forum.lowyat.net/index.php?showtopi...post&p=83940948

Let us know of the amendments if there is any. Thanks again.

Great suggestion! Is there any artwork/design that you are following?

How to reserve? I'm interested, please pm me.

thanks for the review mate, I've corrected it in our local copy.

Emailed you a response earlier. Thanks for the support.

Update 4/5/2017:

The raw materials are currently with our assembly plant and the production will start shortly. So seeing we are incapable of reaching our desired MOQ for the custom casing, we'd like to propose that we go with earlier proposed package (lower price and custom pouch). If this is okay with ya'll we'll start collecting deposits for the actual run. This also means that the casing will use back the international version which we already have a supply of.

Thanks.

I'm ok with that

Okay. Looking forward to it

Hi i am interested. any updates on the ETA. still take 2-3 months to deliver? thx

I'm in for the sound, looks is just a bonus.
So yeah, go ahead.

Cosmetic and design is additional things for me, the functions and sounds are the utmost priority.

Cosmetic and design is additional things for me, the functions and sounds are the utmost priority. IF u can make a pool of it, it easier for to know how majorities feel 'bout it.

@all

Thanks for the feedback.

I guess we'll be proceeding with our production with the current quantities. After we've confirmed timeline with our assembly partners we'll start collecting the deposits.

Thanks again ya'll.

Guys I recently found an e-vendor on Taobao who sells custom Mini USB - USB A cables for mechanical keyboards. The cables are braided have gold plated plugs. They come in a variety of colours and have 0.5m, 1m, 1.5m lengths available. I bought them through Ezbuy hopefully it'll arrive by the time we receive our UD125..
