Hi All I have a Cyrus 3 amp and PSX supply feeding a couple of Mission bi wired 753 speakers. I have had the system for around 25 years and to be honest never really been satisfied with the sound, but as I have owned this kit for so long I have become attached to it! I have been trawling through the ebay pages and toying with adding a decent power amp to try and improve the system. I must be honest all my music I listen to on this system is streamed but does come of a good sound card so actually sounds quite good, its just that I have never felt the mission 753 have ever performed how they should do, and I suspect they need a lot more power to bring them to life at low volumes. Here's the thing, do I buy a Cyrus 8 power amp and use my 3 and PSX as the preamp or do I mix things up and use a different make of power amp as I have heard Cyrus should never be used with Mission. I have thought about buying another 2nd hand Cyrus 3 and PSX and using them as mono amps per speaker with another preamp (my thinking behind this is that 2nd hand Cyrus 3 are cheap but have no idea if this would be pointless). I have a budget of £400 for some 2nd hand kit so any suggestion or sensible advice will be welcome. What has brought this upgrade fever on is I have just purchased 2nd hand kit for my son for his first system which comprised of Audiolab 8000a Technics turn table and Mission 752 and this sounds bloody good compared to mine, so I have to address this. Thanks JT
