ok i bought my zz5500s years ago, some friends bought 5.1 setups with cheaper amps and up him finally spending 1600 uk pounds on his third speaker setup his first 800 pound and 12000 pound speaker setup didnt come close to my zz5500 even base wise but he bought and spent 1600 pounds on some 2 years ago and they were superior to the second hand 100 pound logitec speakers. all his speaker setups were recomended or came with tv speakers and not stand alone brands like say q acoustic or kel or ae to name a few.
The zz5500 are awsome in small rooms and even biger ones im sure.
Now this is where things begin to change.
in 2019 december i deciuded to change my viewing from a tv to a projector and as such was forced to move to a amp anbd seperate speakers as i would have to constantly change my imputs with 4 devices. and the optical out a great option on the zz5500 for say a ps 4 or more to my projectoror is awsoem but you cant manipulate channels well like in the other pc way, jacks lol.
So i bought a denon 2600h and qacoustic 2010i 5.1 but with 3020i fronts.
I takes time to set up the speakers and they ares signicficantly biger than the logitec z5500. the whole centre speacker is same as a q acoustic speaker cone lol.
while waiting for th walls and cabling to be sorted i decided to hook up my center speaker from the q acoustic setup and compare it. remember i actually was wathcing alot of audio movies ready to compare my zz5500 with the 3010i setup on denum. well i was shocked. i personally couldn't tell much of a difference from my tiny zz5500 to the huge centre q acoustic 3090i speaker. i tested it with my none audiophile ears and didnt see any difference that made me think id changed my speaker, i just didnt, but that was on remember opticla output zz550.
But the moment i stiuck all the q acoustic speakers on the denon 2600h it was lightning years ahead . It was more the extra subtlty and acuracy of the management of the sound and its placement that shocked me. my z5500 was great but the q acoustic took it a few levles above.
Well worth the trade. The base on the 3070i wwhich is a very tiny unit was not even close to the z5500 base, thats for sure, its there and itsa more controlable but the logitec z5500 does have louder feeling base even if its more apreciated on q achoustics.
Bottom line if your looking for a great set of budget speakers for your movies pc and consoles then the z5500 is a fantastic bargin, jump up another 800 pounds id recoment q achoustic speakers. If your forced to use optical out on the setup i would consider a proper amp and q acoustic or warfdale 5.1s as the ioptical on the z5500 is great but you loose the control on the seperate channels youd need to mess with(in my opinion) to make the z5500 sound as good as alot of much more expensice 5.1 systems. Remember if i still had control over all those optical channels id have not upgraded. Keep a torch handy as the z5500 led does stop working aFTER 10 YEARS OR SO LOL. you caN GET REPLACEMENTS online all the time, i had 2 of each speaker and was about to get a controler backup. i had to use a torch and my phone as a light when changeing it.
