I found the Gustard X26 Pro (not the R26 which I never owned) much warmer than the Yggi+ LIM. My Office system is the Magnepan LRS+ speaker, which is a tinge on the bright side of things. The Yamaha NS5000 speakers in the Livingroom is a tinge warm. The Yggi+ plays very nicely with both. I would not use the X26 Pro with the NS5000.
When I used the X26 it was with a super bright system and the X26 cooled it down. Interesting, that same system with a new implementation of a key part allows me to use silver cables. I had to use copper before.
On Wednesday my friend, who worked with the Schitt guys, is coming to my place. I am buying one of his amps. He has some golden ears, and I am very interested in his take on the Yggi+ and some other gear I have.
He is going to hate some of my gear, but as they say, "different strokes for different folks."
Some interesting comments on this review.

BTW - the Yggi+ LIM can be demoed at home for 2-weeks. After 2 days I threw the shipping box away.
