Counterpoint SA-3.1 and 5.1


I never see these pre-amps available. I remember them as very easy to listen to while having quite a bit of detail. Are they all dead or is it that no one wants to part with them?

SA-5.1 Uses two 6DJ8 types in the phono stage, two 6DJ8 type in the line stage, one 6CA4 type, one 5651, one 6JC6A and one 6GC5.
Anyone here still using 3.1? I just got one myself and im wondering if i can use the line out  as a regular output like the main out? If im getting it correctly you can use that if the source you’re using has a level or volume output... ?? The line output will bypass the 3.1’s gain mute and balance???
