Maybe you're right about one common thread would be really hard to search in a big topic. True, I did not mean you need stop making separate topics with certain bugs or problems on the forum, just maybe specific questions about device. And  it is always nice when there is a specific group of people who use the same as you and you can talk about the device, links with other maybe not rme devices, durec feature or ask questions in general as in kind of club. I just suggested.

Then let the users of the device here just leave their opinions on its use as i asked in previous post. Because search through the forum, I found only negative feedback, because a lot of threads and few posts in each of them, people rarely write if all is well, but because of the number of bugs there are doubts about the stability of this device as a primary card, and there is no alternative from rme devices for my needs, except that look for an old ucx, which I do not want to do

Of course I do not mean that everyone should give up their business and write their opinions here right now - no.

Just want to hear something different from the problems. That is my "specific question", because from what I read the last few weeks on the forum in the amount of posts when i use "ucx/ucx 2" search tags  I can not imagine kind of statistics or find  who was saying that he uses the device about a year and had no problems. I can see just those 10 +  bootloader issue posts and maybe posts of  people who use this device not enough time, because  now  the impression that each of these devices sooner or later will catch the bootloader  error. That`s why I created this topic, if it violates the rules or ethics of the forum, I'm sorry.

No, i never used extended search on forums, have no experience in it. Main forum i use have comfortable search by few words and i can find few sub threads to see where question i interested in appeared.

May you please quote me an example of how a query should look in the advanced search on this forum to see the positive feedback from people who use this device more than six months, if of course there are such on the forum?

well, i can see that starting this topic wasn't useless. Because i can't see good feedback as easy as bad ones. I always use search before asking and in this case impossible to find needed information for me, if it's easy for you, well, i'm not so clever or not as good in forums use as you.

I can't forget about  dissatisfied people and their posts, because i already told about it above.  That i know people don't write posts if all is ok. That's was reason for this topic to see opinion of users who use device without troubles and haven't wrote anything. about year ago unit appeared on market. now Items on European market out of stock and there still not much feedback.

i think same results quantity as negative will be enough for me .

And yes, for me few bad opinions in case of audio is reason to think twice.

Same with warranty. I wouldn't ask about all this things if in my country  warranty services always worked as they must be.

I know about rme  is similar  to "stability" and it's main reason i eat bread and water for
7 months to buy this thing. I want to forget about all audio driver issues forever and don't get another ones. This is new device full of features, and it is not axiomatic if the past devices have served for 20 years and are still in service that the new one will be so unproblematic. I take into account all the reputation of rme and that is why I set up to buy device from this company.

Thank for detailed information and help with search, i'll wait for feedback or flip through a couple hundred pages in the hope of finding something I'm interested in..If there is no blackout, of course..

sorry for my english

I've the UCX II that I bought October 2021 and I think it's a great device that fits very well with my usage as well as on top of my ADI-2 DAC FS. The one modification I did was to put small feet on it so the distance was increased to 12 mm as the supplied feet are to small, in my opinion.

With the UCX II I can have, for me, a good enough lip synch for my mic during video calls using echo with a delay of 300 ms that the video call program is using for input, while I monitor on a different output to my ADI-2. My camera is connected to my PC using a HDMI-USB converter, thus the need for a delay. This is a hidden gem.

As for temperature I did a few measurements on the UCX II. The ambient temperature is 23C, and I fastened a temperature sensor tip a mm or two from the centre hole in the bottom, towards the rear.

For the test I connected a condenser mic with 48V on, enabled dynamics, EQ, as well as echo. The output goes to my ADI-2 via ADAT. I'm also watching some YouTube/HBO/etc as well during the test on my Genelec monitors connected to my ADI-2, with loudness enabled, EQ disabled but tone controls enabled and set 0. The point is that the devices are not just idling but sees some use.

So, after an hour with the UCX II on the desktop the temperature is 40C.

I put the UCX II back on top of my ADI-2 DAC FS, and after an hour the temperature is now 43C.

Bought UCX II today. May you tell please, are settings buttons  ( 4 black small plastic ones on front panel) have some backlash ? If i rotate the device in  hands, turning it upside down, these buttons make a sound as if something is dangling inside the body of device. Of course, the device during operation stands still, but I just wonder if this is normal for this model or I have a defect of the assembly?
