Yes it coincides with me replacing my 282 and 250DR. I traded them in for a brand new 252 and a brand new 300DR and at the same time bought the Fraim support.
I used the same speaker cables on the 250DR for 9 months and haven’t had any issues. Just good sound. I didn’t even lift or move the speaker cables significantly during the upgrade.
Black Rhodium Foxtrot are :
- 2 core twisted pair loudspeaker cable
- Diameter of cores 5mm
- Capacitance between conductors for 3m length 83pF
- Terminated in gold plated Z plug
I’m running a 5M length.
NAC A5 is about 20pF per m right? So The Black Rhodium Foxtrot are a bit thicker and do have a bit more capacitance, but I had no compatibility problems with the 250DR as I said, so is the 300DR more sensitive to higher capacitance cables?
As regards the power front, yes the AC inlet plug is securely inserted into the PSU and yes the power button on the PSU appears to latch ok. (Also - I only use NAIM Powerline Lite on the entire system).
Here is a more complete description of what I’m seeing happen:
The power down / cut out doesn’t happen at listening volumes, only at back ground volumes.
It first manifested itself when I decided to leave the system running over night playing radio paradise as a means to get hours on the new amps at low volumes.
And when I came down stairs the next morning, both NAIM badge lights on the PSU and AMP modules of the 300DR were off, the power button on the PSU was still on.
I then switched it off, and tried power recycling it, and it didn’t turn on. Thinking that I’d not fully inserted the AC inlet plug, I wiggled it and pushed against it harder. I then tried to power up the PSU and it turned on and I set it to low music again.
After 10 or so minutes of playing music at low background levels, I heard a pop and the AMP and PSU again turned off. Turning them off and waiting over 5 minutes and then turning it on, started it again.
Keeping the volume at low levels, a few minutes later it will turn itself off again.
If I turn the volume up on the pre-amp, its totally fine and continues to play for hours no problem.
In terms of the quality of sound, it’s excellent. Full bodied, good bass definition, great timing and superb detail. I can’t ask for more on that front.
