SX-626 vs SX-580 Sensitivity/Tuner

[TubesGalore]

I have a SX-626 and a SX-580. Though not TOTL they are defiantly quality gear. I love them both as 20/25 wpc is all I need. What I have noticed is the SX-580 seems to have slightly better sensitivity and a more stable tuner. Since the SX-580 was produced about 5 years after the SX-626 I'm assuming the improvement in technology is the main reason?

download the service manuals for both

from hifiengine


then look at the specs for both models

alignment pays a HUGE part in how sensitive the tuner REALLY is.
