Looking for a more portable enlarger (ie Durst 601's) I located another like-new 601 with CLS head. I can avoid shipping charges resulting in the CLS being less expensive vs the M601. I print with both a condenser and color head. I'm aware of each heads properties through experience.
I researched photo-net enlarger posts and saw some complaints. A few wrote the CLS light source was too bright. One had to stop down to f/16 for a 6x6 inch projection. The suggested fix was to dial in neutral density. Others claim the illumination too weak and the corners would vignette.
The vignetting problem seems to be configuration issues.
The weak or too strong illumination is unclear. Typical MF enlargements on my system are 6x8 inch B&W prints at f/8 to f/11 in a range of 14-30s. Is this timer and f/stop range what I can expect using a CLS head without dialing in neutral density?
