new owner of a used Naim NAIT 5Si integrated amp, I would like your opinion on what the seller told me about the amp: all Naim amps do a “speaker pop” when turned on (by design for sound quality reasons, power supply/electrical related), he also told me that the loudness of the pop is relative to the sensitivity of the speakers. My speakers are high sensitivity DIY speakers of 99 db, I am a little worried that the pop might damage my speakers.
Would love your thoughts about this. Speaker shown behind amp, going to be my first proper stereo setup with a DAC connected to my PC.
Most Naim amps do a pop on startup.
Although on my Supernait 3 it’s very minimal.
Best to follow Naim advice for reliable performance and leave on 24/7
It’s always ready for action and stable.
However it makes sense to disconnect during lightning etc.
Or long absences.
The speaker is called DIYSG Titan-615LX, it is a three-way speaker with a 15" woofer, 6,5" midrange and a compression driver in a horn waveguide. It was really just put it together and paint, since the cabinets came as a flat pack and I bought the crossovers pre-assembled, so it is possible for a novice to build their own speakers.
I have actually not hooked up the amp yet to my speakers, still waiting for my DAC to come. I did email Naim support about the pop and received a great answer from Duncan:
"It is perfectly normal, and will not damage your speakers.
The pop you are hearing, is a micro discharge from on board storage capacitors. There will be a minute amount of energy lost when you start up a system, and again when you power down. This translates to the affectionately known “Naim thump”, and this is what you’re hearing.
