Speed up burn in

Im in the very fortunate position of have bought a new 300DR. For some reason I dont fully understand my wife does not want music on 24/7 to burn it in, strange! Is it possible to put say an 8 ohm resistor across the speaker cables have have it running 24/7 to speed things up. I ask out of both curiosity and an abundance of ignorance

I would have thought taking the cable out of the speaker terminals and set so they can sit without shorting would do a job.

Hi Mr Jug I guess that the cables need a resistance to load them

Why not just use it to listen to music when you want. It will ‘burn in’ when it burns in. Why does everything in this world have to be instant now? Enjoy the journey, not just the destination.


Because unlike you I’m stupid

Yes, take your time e and just enjoy the music

I guess putting the amp in a situation of real world load could be helped from using some sort of high bandwidth burn in white noise test track.
Remember even day to day listening over a very long time might not be putting a system into burning in some aspects of replay.
Imagine after a few years putting on a track that really gets things cooking at a certain frequency that’s never been played before.
Remember as well that once Naim amps start sounding “burnt in” they are not far from needing a service :grinning_face_with_smiling_eyes:

I normally set my streamer to internet radio 24/7 at a very low level…so we can sleep. You have no system identified ?

With my 250DR I did leave the radio playing at very low level 24/7 but after a few days gave up and just enjoyed listening to the music and hearing all the different nuances emerge.




With the electronics you just need to leave them powered up.

Instead of trying to put a load* on the speaker end of the cables, why not leave music playing, but wind the volume control to zero?


(* - in answer to an earlier question, an 8ohm resistor would be a poor mimic of a loudspeaker since it would only present a resistive load, without any capacitance or inductance. It would also not change over time or with frequency, which is another reason why real speakers can be such a swine to drive well)

Well if you leave music playing with volume at 0 at the pre, none of it reaches the 300

Speed up burn in ?

It’s better to burn out than fade away.



If you believe that a power amp that has (I understand) already had soak testing when manufactured will still “burn in” to a significant enough degree to make a difference, then I suggest running it as close to maximum power as possible. To not annoy other people in the house you could put the two speakers facing each other as close as is possible without the moving cones touching, whereby there would be considerable cancellation of sound. Alternatively, to do silently run into a dummy load of, for example, an 8 ohm resistor - but do ensure it has a power handling capacity to cope with the applied power: in practice you could use, say, a 25W resistor on each channel, and set the volume control wherever would correspond to close to but not exceeding 25W average output with a source playing continuously. The fact that it is purely resistive and not the same as a speaker load is immaterial in this context:you are simply trying to run the amp on as high a power as possible for however long you believe will achieve the effect you expect.

If running in cables and speakers then some music on in the background will quicken the settling in process.

Good point - hadn’t read OP closely enough!
