Running in?

[admin_exported]

Hi,

I am new to this Hi-Fi products. Can someone tell me if amplifiers, CD players and DVD players also need to be run-in properly before they can sound their best? If yes, then how much time would they normally need? Am trying to decide between PM6002 and CA 540Av2 for MS 902i. Which one would you suggest?

Thanks,

Regards,

Ankan

IMO your amp and cd player will be broken in by the time they take to warm to their optimum temperature. I'd give your speakers a week of normal use before they have settled. During this time your ears will have grown used to your new system which may add a bit of enjoyment. Enjoy!

Most Hi Fi gear does need to be run in before it starts to sound anywhere near as good as it should, I know for a fact that my gear straight out of the box didn't sound half as good as it did after a some serious hours running in.

From my experience the Graham Slee Novo headphone amplifier took around 200 hours before things really started to open up, CA Dacmagic took around 48 hours and my Cyrus CD 8 se took around 72hrs to initially open up but still a few weeks after that kept improving.ÿMy Grado 325i's took a good few days to burn in, but my Quad 12l2's seemed to bed in pretty quickly.

I used to own a CA 640c v2 and the sound was excellent, can't comment on the Marantz but I know CA offer very good value for money... such as the DAC Magic which holds up extremely well playing lossless files through my Cyrus 8vs2 and Quad 12l2's.

I know for a fact

And where might this fact be?ÿ

I know for an opinion that my gear sounds better now than when I bought it, but still sounds gash for 10-15 minutes after turning it on from cold.

I sometimes find that aswell, but I thought only valves needed to warm up. I guess I thought wrong.

I definitely feel gear will improve over a certain amount of time. It seems to vary quite a bit between manufactures and the type of things we are talking about; but a few weeks of normal listening should see improvements.

TBH, I think that for analogue mechanicals (i.e. Cartridges/styli / speakers / headphones) then there is a benefit for the "running in" period. But for electronics, I would say that 1/2hr for all the circuitry to come up to temperature is enough.

My amps are said to be best when left running 24/7, but I can only tell the difference between cold and about 1/2hr - they don't seem to improve further from there.

40 to 200 hrs burning in is needed.

Internal wirings, caps, diodes, op amps, speaker cones, cables all
start to perform at / near there optimum after this time.

Ok, I know this isn't comparing apples with apples, but if the performance of electrical components improves over time (initially) then there's no reason why this should be restricted to HiFi and AV kit surely? A PC should start operating (measurably) better after it has been "run in". Can anyone confirm this from experience? (I certainly can't, but I'm open to offers.)

Good point!

I can understand equipment needing to warm up, but am not totally convinced about 'running in'. Particularly (as I think I mentioned on another thread), cables - I'm don't understand how a cable can 'improve' with use.

And if it can - doesn't that suggest that all cables will get better - even cheap/no-name speaker cable, mains cables etc?

I'm of the opinion that speakers need to be run in, but for everything else my very humble opinion is that it's tosh.

As I have an Arcam system, I decided to have a read through postings made by John Dawson on another forum with regard to this subject. He stated I am not personally convinced of longer term "electronics burn in" in scientific terms (with the possible exception of electrolytics) but our skilled listening staff have observed some kind of effect so we take it seriously enough to recommend a reasonable period of playing in

If he's not convinced, neither am I
