I am having a problem with my X18. I have connected U18 to X18 via I2s and AES Lately I connected an external clock OCK-2 to U18. Now when I play via I2s the X18 , the window display UNLOCK which is flashing. The sound is also impacted. Can anyone help me with this. How to solve this and what is...

I am on Gustard setting. This setting works fine with DSD when I am using HQPlayer which converts PCM to DSD. But when I am inputting PCM signal to the topping DAC than I get drop outs.

I am using Gustard I2S cable from my U18 to Topping D90SE DAC. But there are drop outs frequently. Can someone help me selecting the right setting between U18 and Topping D90SE

A friend from Hongkong said that 1A purple fuse is popularly used there for a Asian 230Vower supply. Again cannot confirm anything. Just an opinion.

Just got two fuses Purple and put them in U18 and X 18.. I could feel the difference immediately even without burn in. Looks like a leap forward in sonic improvements

Well thats a good news as I got my X18 just yesterday only. Together with U18 DDC it is sounding very good.

I just got mine yesterday and I am very happy listening for few hours. Although will need 150 to 200:hours burning in time to sound at its best but initial impression about clarity and sound signature are very good. Also I am using it with Gustard U18 DDC that makes it even better. A very good...

I think that D1se is also very good DAC. but it doesn’t have AES digital output, this is the only thing that is stopping me to buy that. I am using Gustard U18 and AES output of U18 is very good alog with I2s. So I want to have both options AES and I2s Gustard X18 and X26 have.

I am also using Gustard U18 and it’s really very good and took my system upwards by a notch or two. Now I am confused if I should buy X18 or X26pro because the price difference is almost double. I think using X18 with U18 takes you almost to the level of X26 pro. Will you agree. Or should I go...

I am thinking of buying Denafrip Ares 2 or Pontus 2. I wanted to know if these two DACs are compatible in Gustard U18 via I2S connection. Anyone using Denafrip DACs may be of help to me.

My D90SE has been transformed into a new much better DAC after adding U18. The improvements are not subtle but are huge and visible to anyone who has listened .

I am using U18 with Topping D90SE. Some how I didn’t like D90SE on its own because it’s soundstage was much narrower compared to my earlier D90MQA (AKM Version) which I found more musical. But after adding U18 everything changed for good. Now my system is sounding fantastic with much bigger...

Hi I am new to this site as a member. But I have been following this thread for some time now. After reading favourable comments about Gustard U18, I decided to buy one. Also got Gustard I2s cable from Shenzhen audio. I think both U18 and the I2s cable are fantastic products and improvements can...
