Power conditioners and power regeneration

Puritan works but they go cheap at the connectors using low conductivity Brass

on you tube I see people upgrading the Ring contacts with Furutech ,

land for sure the AC contacts should be gold over Copper .

I wrote to them many times Totally ignored , I told them offer a SE model .

why compromise a otherwise very good design . The ones that have upgraded 

said it is a Very good improvement in clarity , it’s too bad Many companies don’t care .myself and others can’t be bothered if the company don’t care .

I have my surge protection at the breaker box a Siemens 

then vh audio has a great one with surge power factor connection you connect just on your dedicated audio circuit .

breakers should be changed every 3-4 years ,unless you have silver plated copper contacts which I have on 2 breakers since the pandemic a5 industrial supply house no longer can get ,from Germany ,but by far the best $50 each at the time 

regular copper oxydizes ,and must be changed for it corrodes.
