I've owned a Creek 4140 (version 1) for years. I was deciding between the Creek and a Naim Nait 2 at the time. I've really liked the sound but didn't really realize how good it actually sounded until this past year when I had a chance to have some other amplifiers in my system.
PS Audio Stellar Strata: Much worse than the Creek. Sound seemed a bit synthetic. Maybe that is due to its Class D design?
Creek Evo 50: Worse than the Creek. Sounded ponderous and slow. Lacked pace.
Pathos Classic One: About at the same level as the Creek
Belles Aria Integrated: Similar in character to the Creek, but better resolution and imaging of the soundstage.
I also listened to some amplifiers at dealers:
Naim Supernait 3: A disappointment given all of the good reviews that I read about it. It sounded a bit gray in tonal color and a bit two-dimensional
Sugden A21 Signature: My impression of the Supernait 3 probably suffered because it was listening to it next to the Sugden. The amount of tonal color and fullness of sound that the Sugden was able to convey was impressive.
