and let it burn in.
There's no need to do that, as this isn't the same as burning in a pair of headphones. Just play your favorite music through it. I've actually heard of people warn that you shouldn't play constant frequencies (like those found in Wavegenerator), since it might damage the amp. Not too sure about the last part, but I do know it's absolutely unnecessary.

I don't understand your post.
If you want burn your amp, it's need a load, an headphone or 10 ohm resistance to have some signal witch run inside the amp.
Maybe i have wrong, but it's the way to process to burn caps and it's preconise by RWA ( for the load, not for burningwavegenerator)

Unless the way it is burned in, has an effect on the sound.

There is soon a lot of thread about burning process.
it's more interesting to know how sound change with time of use.
out of box, after some hours of listening sessions....Time to obtain mature sound.
synergie with sources, head or hearsphones etc...

It is all interesting. And the value of a forum is to share experiences, mistakes made, etc....

So, I look forward to your impressions.

In the following thread, Jamato8 discussed the changes he heard as his burned in, and I may also have a few posts in there about what I heard change during burn-in: RSA **Predator** A review in stages ** With some images - Head-Fi: Covering Headphones, Earphones and Portable Audio

I didn't like mine out of the box, but by 350 hours it will have surpassed your Hornet (with 2 weeks continuous use it surpassed my Tomahawk that had 800 hours). By 600-700 hours you will be addicted to it, and by 1,000 hours it will be mostly done maturing. I basically had mine running for over 6-7 weeks with a 1 hour break a day, to get it fully burned in.

Mine is the one Skylab reviewed here: Review: Portable amp roundup! 37 portable amps reviewed and compared - Head-Fi: Covering Headphones, Earphones and Portable Audio

Here is my review: http://www.head-fi.org/forums/f5/min...-micro-306883/

I have started to do the same things.
Mine is on the grill and have 20 hours on it now.


So out of box :
Too much separarte frequency - sound like there is a loudnes- Not natural sound- lake of openning.
clear, detail, punchy.
After 10 hours :
Lake of Medium frequency, egalisation bw bass and treeble.
Sound sometime like a wave with open aera.
It's look like there is something witch always change, sound is absolutly not stable.
clear, detail, punchy.( it doesn't change )
After 40 hours :
Detail-Punchy -harmonisation bw bass & treeble
Wave effect is go away, sound is quiete stable.
Lake of open aera -lake of medium -lake of natural sound.
The improvement continue...

After 50 hours :
This is the born of the amp.
it's the minus burning time to have a stable amp.
Before, i wasn't able to keep the headphone on my head more than few minutes.
Now, sound is ok.
Punchy, clear, detail with great bass and good treeble, medium take there place.
It' doesn't sound so good than my hornet, but start to comp with.
wait and see...

Nota :
I use my burning plug to burn the amp.
It's an ordinary mini jack with 10 ohm resistor.
So, maybe if you use a differente load ( as an headphone 32 ohm) time could be more longer to obtain same result.


80 hours :
Nothing special.
Good stable sound.burning process do this job.
Lake of open aera.Lake of natural flavour, for the rest it's perfect.
More detail and powerful than the Hornet.
Nota :
I burn it with the dac and there is a lot of change.
The dac sound cleaner and less artificial.
At the begining, my iMod sound cleaner as source, now it seems to be egal than PC-USB-Predator dac.

100 Hours :
Sound indentical as 80 hours, but too much Bass now (maybe they take there place ).
i'm waiting for an improvement with medium and open Aera witch give it a better natural sound.
if it's hapen, sound 'll be perfect.

120 Hours :
Magic sound is born.
all is perfect.
Deep bass, great treeble, perfect medium.
Open Aera is there witch give a natural sound.
Detail and more punchy than the Hornet, it drive without probleme my GS 1000.
I'll continue the process to know if there are some improvement, but even if it stay like that, it's sound GREAT.

140 Hours :
Sound as 120 Hours, but Higher Dynamic (witch was soon great ), it's incroyable.
it's sound like a great dynamique powerful Amp, absolutely not as an tube amp ( like my Hornet ).
Very sensitive on the source quality and with an immediate respons.
I hope during buning process sound 'll become more warmer.

180 Hours :
No change compare to 140 Hours...

200 hours :
Change in the treeble section.
Higher and clearer.
More equilibrate bw deep bass and treeble, sound great with the mid, just a lack of warm and open aera...
Great presence, 3D scene.
Sound change slowly comparse to the begining of the burning process.
Changes are subtitles.

220 hours :
The sound i'm looking for begin to appears.
Dac, principal change, it's start to change and become more "Musical", less neutral and very detail.
It's like you have pull off a filter, incredible..GREAT improvement.
Sound of the amp start to become more open and have a great backstage image.
Wait and see, but it's on the right way.

260 hours :
Great sound when i use it with the internal dac.Nothing wrong to tell.
When i use it with the imod source:
Sound ├ęgal to the Hornet with alo imod doc cable (blackgates inside the plug).
Don't comp with the Hornet when i use Pvcaps ( less natural sound) and prefer listen it throught the usb cable to my computer for the moment.

300 Hours :
Like at 260 hours.
Perfect sound through the Usb Dac, only pleasure.
The best sound i have heard until now.
Concerning the analogical source (imod and Pvcaps), i'm not in love with it for the instance, i prefer the result with the Hornet.
Not enough Open and Warm.
So i continue the job.

340 Hours :
Great sound through the USB dac, very sensitive with the quality of the records, you heard everythings.
More pleasant sound with imod source.
The sound get slowly more open and more natural than before.
it's like there is a better equalization bw bass, treeble, medium.
Great presence an 3D sound with the 2 sources.

500 Hours :
Sound have really improve at 480 hours and continue slowly.
All is in order, and it's very pleasant to listen it with or without dac.
Detail, dynamic, NATURAL.
there is a little lake in the open aera and warm compare to the Hornet, but sound is globaly BETTER.
The Predator is very sensitive on the record quality and reveal all the glorious sound or trouble...
It's a killer !

i'll continue until i obtain more warm and open aera, but this burning process worth the pain.
It's a new amp, absolutely not the same than out of the box, and think it'll be my better amp.
Perfect for low volume level of listening session.


550 Hours :
Pleasure.
Sound reach the stars.
I have obtain the sound than i was looking for since the start.
It's my better amp at this day.
I was so deasapointed at start of the burning session, than i just want say to the others, take time to burn it.
I'll continue beacause i'm sure there'll be some improvement, but it's yet my best amp (and you know, i'm in love with the hornet).
500 hours again and i'll give you a detail comment about the sound.

700 hours :
Predator is definitively better than my old Hornet.
Same sound signature with just more dynamique.
Perfect amp.
my old hornet can comp with Predaor if i use x cryo sylver cable from Alo.
So the gape bw the 2 amp is not so big and it's confortme.
When you choose an RSA Amp, it's always a top choice.




Burning process, wait and see...




I use a mini jack with 2X5 Kohm as load and i'm sure it's the reason why i obtain a great sound with only 120 hours.
I f you use a 32 hom headphone as load, time 'll be 3X longer for the same result.
I hope it cans help other people to burn it, and the special load worth the job.

Rico67, I am in no way trying to belittle your intelligence at all, but it took me a long long time to understand how to work the gain switch in concert with the volume pot to achieve maximum results, for example, I can't listen to HD650's on High Gain, just Medium, and my SE530 IEM's don't like Low Gain, just Medium. I will say now that each person is different and the phones will vary, I know, just wanted to say that it took me a long time to figure that out.
Enjoy,
Scott

Hi Scott,
no problem at all.
Everyone have its own taste.
I'm burning the predator for the moment, so nothing is fixed.
I use an GS1000 with gain on the Medium and its work ok.
The only thing strange is than the GS1000 is very Open, and for the instance with Predator, there is a lake.
Appart it, the sound is Great.
the Predator sound better for the moment with the usb Dac than link on my Imod.

I do this post only to indicate the improvement of the sound during the burning process.
That' all, nothing else and hope it can be useful for the new purchaser of this beautiful amp.

Keep us updated as you burn it in, I think your information is useful to us all, especially the potential buyer. Thanks Rico.
Enjoy,
Scott

Hi,

I would guess you should have added another 300-350 hours by now, and I wonder what your impressions are since your last detailed "change vs hours" post on the 9th?

Thanks!
