    ZA3 - XLR Op Amp swap

    In the end, I settled on the following configuration of opamps: Sparkos SS3602 for XLR, Burson V7 Pro Classic for the right channel and SS3602 for the left channel. You don’t have to install the opamp in the left channel, but I liked it better this way, feel like its adds more transparency to...

    ZA3 - XLR Op Amp swap

    I'm so surprised with performance of these two little amps that I want to test another theory: if removing ops from the left channel still affects the sound in mono mode, it might make sense to try putting another Sparkos in the left channel. As soon as I buy two more SS3602 opamps and try it...

    ZA3 - XLR Op Amp swap

    Hello! I recommend erasing the old thermal paste and applying new one (arctic cooling mx-5, for example) so as not to accidentally overheat the amplifier. If you don't use sub out, you can remove these opamps. I pulled them out at the same time as the left channel opamp. In my opinion, the...

    ZA3 Mono Mode Sub Out

    Hi! I connected the subwoofer to the sub out of one of the amplifiers. The low frequency information is usually the same for the left and right channels, so there is no difference.

    ZA3 - XLR Op Amp swap

    Many people prefer MUSES02 for their warm sound, maybe I'll try to play with different op-amps later :) I've swapped op-amps in XLR for SS3602 and immediately noticed that a little harshness in the high frequencies went away, but at the same time the highs became much darker. I waited about a...

    ZA3 - XLR Op Amp swap

    I connected subwoofer to the sub out of one of the amplifiers with RCA. Low frequencies are usually the same on both channels. That was surprising, but after many years with high level connection, I feel that it just integrates better and sounds better with low level input. I’ll swap opamps in...

    ZA3 - XLR Op Amp swap

    I also decided to swap the opamps in the XLR. But I would also like to change the opamp(s) for the Sub Out. Do you need to change one or both Sub Out opamps in mono mode?

    ZA3 - XLR Op Amp swap

    I've tried to change op-amps in the XLR (ss3602), it sounds much better than stock, but when you swap them in the right channel, it sounds the best. Interesting to try to swap op-amps both in the right channel and the XLR. Would there be an additional benefit in sound?

    ZA3 Mono Mode Sub Out

    Hello! I have two Fosi ZA3 in mono mode and I want to connect a subwoofer (Rel Quake) that has 1-RCA low level connection and Speakon high level connection. How should I do that?
