This thread had my anxiety up a bit. Back in the day I had a threshold 400A which I loved. It was a customer trade in so I bought it from my boss at a good discount. Long story short, I took it home and it sounded awful, boss said get new main caps installed, problem solved the amp served me and sounded amazing for the years I had it, (also kept my little apartment warmer).
I bought a Cyrus two with a PSX power supply and it arrived last week. I’ll admit some trepidation firing it up. Seller was very honest, the amp that was built in the mid 80’s had never been serviced, never needed it. It sounds great pushing my TDL compacts in my mancave room. If I could source a pair of Mission 767's, a Cyrus CD player and an Ariston TT I will have my dream system from when I was 25.
It just had me wondering if there are designs that are more prone to stress capacitors, and other designs that are kinder.. I’m not an electrical engineer so all I know is the set up will sound great until it doesn’t, then I’ll worry about the capacitors.
