I have a Luxman CL-38uC, and a Luxman CL-35 III (which was reviewed by Audio Critic in issue 1 (1977). The Audio Critic review is irrelevant with regard to the CL-38Uc.
The Luxman CL-35 III is better than good, When I heard it recently compared to an Audio Research SP-3A, I and others listening preferred the Luxman CL-35 III.
In my system the Luxman CL-38uC replaced an Aesthetix Calypso/Rhea, and I think it sounds better than the Aesthetix equipment it replaced.
Compared to CL-35 III the imaging is better, including a larger more defined sound stage, and blacker background. A synergistic combination with the rest of my gear. My system is posted so you can see it here on Audiogon.
I have not heard the Manley Chinook phono stage so I don't know how it compares to the Luxman, but I did like the Luxman better than the Aesthetix Rhea.
