So far it's been great... let me summarize my journey.
I started with a Innuo Zen MK3 years ago. Liked it so much i upgraded to a Zenith MK3
I had the Zenith the longest. I have a nicely revealing system, and I tested using the Zenith as Roon core vs Sense.
Sense always won. It was just more open/organic to me (hard to describe). Not night and day, but enough for me to notice.
I then decided to try out a Grimm MU1 for the fun of it. So i sold off my Zenith and had the MU1 for a while.
It was good. I feel the build quality of the Innuos is much better than the Grimm. I liked the Roon interface.
But since i preferred Sense in the past and don't need to pay to subscribe to it (unlike Roon), i had my eye on the Stream3 since it was announced.
After the long wait it finally arrived. and i'm happy that the Stream3 replaced the MU1.
Once again i feel the Stream3 is a much better build, more sturdy, the ports more secure/tight, etc.
And finally Sense sounds better than Roon (or Stream3 sounds better than MU1)
So i'm currently set for a while, looking forward to the new features that Innuos introduces in Sense down the road.
