Thinking about buying JBL Synthesis components


Standard Member
I’ve been shopping around for some new audio equipment. I have looked at receivers and separates from many different brands. Arcam, Anthem, NAD, and JBL Synthesis. As far as what I want, I honestly don’t know for sure but gravitated towards separates this time and have narrowed it down to Anthem or JBL, leaning towards JBL. I have to go with used components as I am not rich, and plan to buy things slowly to help with sticker shock. I currently have a Yamaha V6a or whatever the model is with HDMI 2.1. HDMI 2.1 has shown to be basically useless at this time. I have a PS5 and Sony 900h with HDMI 2.1, but I’m not noticing much, so keep this receiver isn’t in the cards. It sounds ok, but it’s time to get some better sound.

Is an older JBL processor, like the SDP-25 worth investing in? Would an Anthem processor sound better but still work ok with JBL EQs and amps or is best to buy the same components?

Ive seen 7 or 8 channel amps…would that be a better or worse idea then buy several 2 channel amps? In case amps go bad, I’ve been in a situation where having multiple 2 channel amps saved my bacon (movie theater)

last but not least, I was looking at the JBL SDEC 3000 or 4000. The connections the back confuse me. The Phoenix Combicon style confuses me as to how or why they are used.

I know these are a lot of questions, but the interwebs aren’t helping to answer many questions about these old components. I wish I could afford new, but I can’t. If anyone has this equipment or can point me to a great resource, I’d much appreciate it!
