i am having a hard time finding another z5500 because people are just out of there minds on ebay. trying to sell beat up systems for Enormous amounts of money.  i almost had a brand new never used set. until someone came in with a crazy bid and outbid me of 350  there becoming scarce 

  the only problem i have with Cerafine. is. i would have to source them from ebay. and then the question comes to play whether or not i am getting Genuine Caps. i might just stick to the Silmic II  unless theres a place i could get the Cerafine thats a know place

yes i did tons of research for hours! and i learned quite a bit! pin layouts . i also learned a lot about ADC's and so on. so i completely get it now.  as far as the D2audio chip is concerned. it doesn't seem like a alternative will come easy. as the company on sells in big quantities.. i would...

  you dont think any of these would work?   http://www.mouser.com/Semiconductors/Audio-ICs/Audio-A-D-Converter-ICs/_/N-4gxil?P=1z0yr4yZ1yx6n13   i think i might be will to try a cap swap.  according to the pdf the ADC's are tssop 16 but i am not understanding much else.   but i think i...

well there was on OP AMP which was the same old OP AMP from the Z5500 R4580I series. I changed that. i am not sure which it controls. but all is good as far as sound. now there are A/D converters  3 for center/sub /RL RR/ and FR FL.    whats there now is   ...

  i like it . i have to find another Z5500 set at a good price

omg! i cant believe how the speakers sound with this tweeter! def worth the upgrade!  Dayton Audio  ND16FA-6

new tweeters. new mod. more of a finished product. i didn't have a stepping bit. so its a tiny bit unfinished. i will get the bit before i do the rest so they look perfect. still have to put it back together. and solder the capacitor    

  i got a 2.2 in there now but not a Nichicon.  also i ordered some new tweeters to test make it more of a finished product. my Z906 came today and i must admit. it sounds really FULL and awesome! i was expecting to be disappointed but i was not.! but heres the question. is it worth modding the...

guys who likes the tweeter mod?          

well i scratched this exta z5500 to the side for now. scrapped all the landings. and everything is prefect. made sure all the traces are intact... will check more later..  i know the Z906 are not as good. but i went ahead and purchased them. i guess i will mod them as well :D     ps. on the...

i changed the capacitors on the pre amp board. i initially had bass. then i lost it. i re installed the old ones and still nothing. very little. what else would cause this. i do not have the newer pre amp board. its the bigger older one

the humming I have is from the sub alone. if I remove the Coil. no more hum. I tried to isolate with rubber but still seems to want to hum. only replacement might be the cure. for a better quality coil. also is it possible for the coil humming connected with pop when using fans or lights?

  all done with the 2nd unit. All Nichicon KW series Every Cap. and all OP amps Changed. sounds Amazing!   but Popping is still very Present. only when its connected from something. say a TV. via optical and so it the HuM, when off and switch on.  even without the Sub Connected. and turned on...

  slightly off topic i recently got a second set. z5500 i noticed this one POPS when turning on and off any switches. we have very good power. and my other set never did this. do you know what might be responsible for this?

seems like the only difference would be current one is 6ch later one is 8ch

would upgrading the cirrus logic chip to a better one help anything too? just curious

     one other question. i got the main caps 10000uF but they are snap ins so they will be much bigger. i was going to lay them down on the pcb and glue them in place. but i heard people using the GE silicon type 1 wont harm electrical components. GE claims its neutral cure  any experience...

Thanks for the reply .

hey guys new to the forums. but not a nooby to electronics. so i wanted to take on this project and bought all the parts. but for the life of me couldnt find 1 pcs 4700uF in 75v. or atleast 1 they wanted to sell bulk. so i purchased a Nichicon Muse FW in 35v which is still higher then original...
