Hi I have recently been given (on long term loan) a Naim Nait 5i from my father as he has gone back to using his Quad that he has since the 70’s after a process of restoration. The Nait was bought in Sept 2010 and has been in a cupboard unused for the post 2 years.
After an initial issue with a ground loop hum which I fixed by grounding one of the audio inputs directly, the system was sounding great. My setup consists of the Nait, Pro-Ject T1 Phono SB (brand new), Apple Airport express (for streaming), B&W 607 speakers (brand new) with chord company connectors to link everything together.
After a few weeks of enjoying some great sounding music I started to notice a fluctuation in volume whilst listening. This happens randomly but often and is very noticeable, like a flicking between high and low volume. It happens with both inputs I have ie. turntable and Airport, I have swapped inputs but does not make a difference. I have wiggled cables and wires whilst listening to see if it is a loose connection but it doesn’t seem to be.
Does anyone have any ideas? Is it the Nait or should I be looking elsewhere?
I would appreciate any suggestions as you can imagine this make listening a very unenjoyable experience.
Many thanks
