When connecting a snaxo 362 to mono blocks which have rca inputs, do I need to use two separate cables from the snaxo for each mono block, or can I just use a stereo Din to rca cable from one snaxo din socket to the mono blocks? Does it make any difference which method I use?
Yes, you can use three stereo or six monoblok amps. The SNAXo 362 accommodates either.
No need for a splitter. Just three sets of DIN4-2x RCA phono cables. Only issue would be the tails to the RCA phonos. They may need to be quite long to reach each socket. Also the SNAXO can be fussy about the cable it drives - otherwise you can get instability with all kinds of issues including RF and poor performance. This is why SNAICs are not recommended here rather Naim’s active leads which are similar to the DIN-XLR cables.
