Hi i just get into this rabbit hole and got myself Aune S9C Pro dac/amp.

As far as clean power, low noise floor concern. We turned to power conditioner linear power supply and even change to power cords. In order to get effective results does that mean we have to change everything starts from power conditioner down to linear power supply and power cords all at one time?

Among these 3 ways If i just get a good power conditioner while I still use back the generic free plugs from the gear will that be sufficient or even with a good conditioner I still need linear power supply whether if I'm using ifi purifier or allo shanti psu on top of power conditioner.

Can someone share your thoughts.
 
Don't worry about that stuff.

The Aune S9C has a linear power supply already.

Save your money for speakers or headphones now.

There is no evidence to show that expensive power cords or power conditioners do anything to improve the sound.

I use hospital grade power cords just because I like the solid connection they make to the outlets and they are inexpensive, but I don't think they do anything sonically over the cheap cords included with gear.

Are you in the US or ? Why do you think your power needs "conditioning" or "cleaning"? Power cord wasn't long enough or broken in some way so you replaced it? Sounds like you've fallen for some audio bs, tho.
 
The power supply in your device already filters the incoming power. Absent anything extremely abnormal (such large voltage sags/spikes) you don't need to don't need any devices in front of any audio component. And certainly don't worry about the power cord. As long as it's fit for purpose and isn't poorly constructed, there's no issue. And if you do have an issue like a power cord that isn't fit for purpose or large voltage sags/spikes, the symptoms won't be subtle. And a power conditioner or expensive "audiophile" cords would be the wrong solutions.

Basically, save yourself a lot of money and anxiety and don't buy into that stuff. Return anything you've already purchased, if possible.

Power conditioners, power cords, linear supplies.


None of these will have any benefit for audio quality. Any decent equipment already has a seriously impressive filter that removes noise from the power - and that is the existing power supply.

This has been measured here over and over. These overpriced items have never been shown to provide an audible benefit.

Power conditioners might be useful if the power quality is so bad ( Regular dropouts or surges) that there is a risk of damage to equipment - but not for improving audio quality

Fancy power leads or linear power supplies are always snake oil.
 
Why did you buy such an imperfect device In the first place? It simply should not show the problems you are trying cure.

Well, it doesn't IMHO.
 
So bottom line everyone is suggesting use back the generic cable and plug, additional linear power supply or conditioner won't make any difference since S9C already comes with a linear power supply rite?

Still more curious why you thought that was some sort of way to go/solution.....

Slight correction:

Linear PSU won't make any difference since the supplied PSU - whether linear or switched mode - will already perform perfectly adequately at filtering out mains and other noise.

Please describe the actual problem you have. It isn't clear to me what it is at all. Try forgetting any possible solutions you think of for a moment, focus on the problem itself. What is it? Does the DAC produce audible noise? If so, are you sure it's that and not another device in the chain?

Please be specific and precise, and we can help you.

I would imagine he has read on 90+ percent of audiophile sites that you don't get good sound until you have replaced all your power cords with expensive unobtainium. Have linear power supplies everywhere, and conditioned the mains until it is silky smooth like being washed in rain water.

This should not be a surprise to us - we see it all over the place. Nor is it a criticism of the OP - it is difficult to see past this stuff when it is everywhere. Impossible for most who don't have an engineering background.

I'm just glad he came here to get a dose of reality before wasting his money on expensive but useless audiophile jewellery.

If you want to try ANYTHING, try some clip-on ferrites on the standard cables and make sure the connections of said cables to amp and wall socket are clean and firmly plugged in. I once lived in an area where I felt these ferrites made a tiny difference to my active speakers and CD player (my preamp and matching amps before going active, were designed by an ex rf engineer who made damned sure his products were totally immune (measurably too) to mains nasties!

The ferrites above are dirt cheap, easily sold on if they make no 'difference' to you. I still use them on most things with smps as at worst they're absolutely harmless ;)
 
Thank you all for your input.
Have been following some trusted audiophiles from youtube like iiwi or Joshua to name a few for quite sometime heard them mentioned linear psu or conditioner before even though they did reviewed S9C but never mentioned the need to use linear psu on this unit as I thought is a very basic thing in order to really enjoy the most your set, conditioner or linear psu is a must on all system or else you are missing what your set can deliver. Noisefloor is a hindrance to every set of amp or dac as I thought might appear on S9C especially im using macbook connect to external hdd to play flac or dsd music.

I'm starting to think there is no actual problem with your stuff. It plays fine, right?

I would suggest recalibrating your "trusted audiophile" filter.
 
I was thinking of using upnp and looking at Fiio SR11 streamer but than again is there a need of streamer?
