If you read some other their reviews you would see that this one is pretty negative.
Marcin tried SAM for wrong speakers and gave up (as expected) - it's not used for the rest of review.
It appears they were just polite in the end, not wanting to be rude (probably because of importer / shop which gave them Devialet for review) - the last sentence you quoted saying "it's not hi-end, but just good looking Hi-Fi" is saying everything about the device which costs 15k €.
Obviously, both of them (there are two "independent" reviews) like some different kind of sound...

Life is not measured by the number of breaths we take, but by the moments that take our breath away...
