-It is not well known, and therefore suprising, but the Orion 565 holds a few advantages over the Orion II 566 in terms of performance:​ 
  
 1. The 565 provides stereo line out connections on the Aux I/O connector where the 566 only has a single line out 1. The 565 provides stereo line out connections on the Aux I/O connector where the 566 only has a single line out

 2. On very strong s9++ signals where the hardware AGC kicks in, the 565 receiver stays clean but the 566 receiver is prone to occasional distortion. ​ This has been verified on four out of four 566's tested, which spanned the entire production history. 2.

 +===== 566 Advantages Over the 565 =====  
 + 
 +1.  Color display is MUCH more attractive than the 565 monochrome display, which loses contrast as it ages and may need to be replaced 
 + 
 +2.  Ten-Tec used superior connectors on the 566 encoder signals, which is a known problem area in the 565
  
 +3.  The 566 offers 600hz and 300hz optional filters without an extra preamp stage. ​ The 565 work-around is to use the Inrad #762 600hz filter in the 1000hz filter slot.
  
-Of course the 566 holds a major advantage over the 565 with its crisp color display and the 566 also seems less prone to the 565's intermittent encoder issues.
