I’m running a technics SUV 650 amp had it cleaned and re capped it’s very powerful and is doing far over it’s rated output, they were know to underestimate at that time, I love the sound and will not leave it go unless it smokes itself. Now.. that’s old👍🤣
My Technics amp was rated to 120 Watts per channel and I had a pair of Sony speakers that cut the amp out at 20% volume.
A mate went on holiday and lent me a pair of Wharfdale E90's and gave permission to turn up the volume on them
So one day, turned the treble and bass knobs to suit, turned up the volume to arroung 5.5, windows were shaking, neighbers were out, and the police were called. Did take it to 7 but dare not go any louder as they were not my speakers.
Wish I could get hold of a pair of the E series
