Impression of RME UCX II
yoshitaka, 20.08.2021
I am a UCX and Babyface PRO FS user.

This is a comparison between Babyface PRO FS and UCX II.

Owned equipment
Speaker Genelec 8331 (purchased at Thomann)
Headphones SHR1840

External processor
RUPERT NEVE DESIGNS Portico II Master Bus processor
SSL FUSION (purchased at Thomann)
Analog synthesizer

The first impression is the headphone amplifier.
Babyface pro fs sounds brighter than UCX II.
I hear more high frequencies.
The UCX II has the impression that it sounds a little more subdued than the Babyface pro fs.
If you like flashy sounds, Babyface pro fs is a good choice.
But UCX II is also very good. Enough for me.

Next is the impression of speaker out.
You can see the sound better with UCX II. Overall.

About input
I think the mic preamp, other inputs, and the UCX II are very good.

Both the UCX II and Babyface pro FS sound great.
UCX II is a very good item because I need a lot of input.

It's also worth noting that the major difference between UCX I and UCX II is the addition of AES.
I own a genelec 8331.
The difference in sound is obvious when connected to 8331 with AES.

If you are considering UCX II as a replacement from UCX I, I highly recommend UCX II. The UCX II has a good view sound.
