Ordering a HiCap DR for SN3
I understand the connection with supplied Snaic 5 only is from HiCap DR socket 4 to SN3 upgrade preamp-out top socket?
Does the upgrade power amp-in socket below that on SN3 require a new smaller Cap cover?
Also on here I recall posts re connecting HiCap DR socket 3 to SN3 upgrade power amp-in socket with snaic 4-4 TO PRESERVE SIGNAL? is this essential?
