To accelerate process, we will be slowly rolling out shipment in a first come first served basis over the span of 1-2 working weeks. These can be tracked in the master purchase list located in this thread. We would like to kindly ask for your help to complete the full payment so we may ship the units out to you as soon as we can. If you do so, please let us know your shipping details as well. Thank you.

23/06/2017 - The casings have arrived. Assembly has also sent out assembled units. QA and QC will begin after Raya. Hopefully we can start sending out around Mid of July.

08/06/2017 - POUCHES Arrived.

17/05/2017 - We're starting to collect the deposits for the reserved units. Please refer to the end of the first post for more information.

16/05/2017 - PCB Assembly has started. Colored Pouches are secured. Deposit collection will start soon.

04/05/2017 - Raw Materials are currently with our assembly plant, production will start shortly.

29/04/2017 - List updated. Further updates -> https://forum.lowyat.net/index.php?showtopi...&#entry84726268

03/03/2017 - Some of the proprietary parts have been secured, so production will be faster than suggested timeline if we manage to get our MOQ. The MOQ is primarily due to the custom casings.

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 Andre

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

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.

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.

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.

thanks for the support

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

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.

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?

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:

Hi salimbest83

The UD125 is designed for this very purpose!

So the answer to it is yes.

nope.

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

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.

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.

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.
