Recently my z5500 control pod started giving problems. Will suddenly go blank. Then it died totally. Apparently the cirrus chip died. After around 13 years of good service.
Was really reluctant to throw out the good speakers and sub (thx certified man), so this is what I did

I bought a Yamaha rx-v6a, hooked up the satellites to it. Made a bypass cable for the sub. It is now in 5.1 form, but I will buy 2 additional bookshelf speakers soon to make it a 5.1.2 system.

I ordered some speaker foam surrounds from shopee. They just arrived. I will refoam the speakers, including the 10" sub, as they are disintegrating.

The satellites are 60w 8ohm and the sub is 180w. They work really well with the Yamaha avr, especially after the automatic configuration.

If your control pod is dead, you can also make a bypass cable for the amp in the sub. Basically a direct 6 channel connection to the amp. I decided to get an avr cos I wanted to upgrade to Atmos. I think it's a good way to still use the excellent speakers. The sub low pass cutoff is 100hz, which is a bit high, but can be adjusted. The satellites are full range, though they lack separate tweeters, but again the avr can compensate for that.
