Sorry to took this thread, but this fit me too.
Today my non programmable PSU (2x30V/5A) died, kind of, it auto set to max voltage 53V alone and killed expensive fan that were connected when accident happens. Reboot, turn knobs to 0 does nothing, PSU is 32V per channel and is acting like series, and it really output that voltage to CH2, even the probes are not in series configuration. Anyway the PSU got fire +/- two years ago, since then i use it to spare money but now is the time for refresh.
My needs are at least good programable 30V 5A, the 3A will not suit me and dislike to put parallel to get those 6A max, but if parallel acts like automated way with a push of a button, for example CH2 will set as same voltage as CH1 automatically i would consider it, eg: SPD3303X-E
After read this thread i found the SPD1305X with good price and features, but also saw Rigol DP711 which cost only 40€ more.
SPD1305X VS DP711 what would be the better choice?
There's also the Korad 2x30V 5A, is that any good compared with the models above?
