Shout out to Stoner Acoustics for being responsive and professional!
My unit was connected to a (suspectable) faulty OTG cable, the unit was then no longer usable. I contacted them and they offer one to one exchange.

I just received the replacement unit today. I am using it now to listen with recabled Alessandro MS-1. It just sounds so flawless. Recently, I have listened to a very nice headphone, which is Master & Dynamic MH40 (USD$399). I would say UD125 + my headphone now, it sounds so great, at least same level to the M&D MH40 if not better.

Proud of this Malaysian product!

---------------------------

I am overwhelmed of how good it can drive Koss KSC-75. The handphone sounds so goosebumply good now!

Thank you for your warm support.

You are definitely using the UD125 the way we intended it to be by design, i.e. which is a compact all-in-one DAC Amp capable of being used both as a line out and as a powerful amplifier. Unfortunately our marketing message is not clear and strong enough and some customers are still under the impression that it functions primarily only as a DAC.

I guess the legacy of the UD series does leave a strong impression on the customers. (This is the first UD of the series that features a complete feature set)

350mW Low Impedance Output


How do you define as low impedance output? 16 ohm? 32 ohm? Can I get a list of mW vs ohm, it would be very helpful.

EDIT: I forgot to share this image I got during my search of more descriptive info on the filter sound effects we can get out of the AK4490.

I'm still wondering why I don't notice any sound changes if I change the filters, oh well. That's why I've decided to replace my M-100 with M1060 (still waiting for the shipment).

We do not have these plots readily available at the moment, but we may publish some of these specs in the near future.

One of the German Reviewers made a measurement and it is around 0.1 ohms from 0 to 20 KHz.

You aren't suppose to hear a "huge" difference from each filters. Most designers simply pick one and fixed it in the firmware so the DAC only runs on one filter. However we wanted the customers to have something nice to experiment and play around with.

You can see how the filters differ from each other if you do some measurements on an Analyzer, but chances are you might not be able to actually hear these subtle differences.

I forgot to replied that the replacement unit is working fine. No more distortion at the start nor ending of every song. I'm currently using it with my Edifier S730 since I don't really like it much when pairing it with Xonar Essence.

It just suits S730 better. Less sibilance, and when I'm using no led filter, the bass is less exaggerated. I get less Brrrrrr from the powerful sub. Also I don't have to deal with the stupid low volume whenever I'm watching movies with 5.1 sound. It just route beautifully instead of low vocal.

I might have like the red led with S2000 but with S730, I definitely prefer no led.
