I always felt that the sound of SC8850 was not as good as that of SC88Pro. I thought it was because SC8850 used a switching power supply.
After replacing it with a Cable Creation power cord, the sound became smoother and sweeter. Now the sound is as good as SC88Pro, if not better.

You can listen to the video above to see if the sound is more comfortable and better than other SC8850 videos.

aah I see we found the audiophile. still, you can do better, you need a mogami gold nitrogen infused pure copper 1 million strand cable! Only then will it be suuuuuper smooth and suuuuuuuuuuuuuuuuuuuuuuper sweet. It would be like have Tom Lord-Alge on your left and right ear, constantly mixing to universal harmony.

Does this cable has current flow direction? 😁

Modern HIFI is garbage
My speakers are from the 1980s
Good sound quality doesn’t necessarily require a lot of money, but it does have to be done right

The thickness of the copper wire and the plastic cover of the wire affect the sound quality,
materials have a great impact to sound, the principle is similar to a musical instrument

But most people don't need to pay attention to these, they only need to pay attention to the sound difference

I'm sorry, but I've two bad news for ya. First one: The thickness of the copper wire in the power cord has nothing to do with sound quality, but with amount of current it can "carry". And second: g00gl, wiki....a and similar sites, known amongst zoomers as "sources of universal knowledge", can not compensate for the fundamental gaps in secondary education.

The only things that can affect the sound quality from power cord or plug is ground looping or bad grounding.

? sorry I don't understand what you mean, english is not my mother language
After changing the cable to Cable Creation (it's very cheap), the sound will be a little more comfortable and better.

The thickness of the power cord will obviously affect the sound.
For example, if you use 22AWG wire for power cord, the bass will be significantly reduced.
If you use a 10AWG wire, the sound will be muddy. It is best to use 14AWG for power cord.
This Cable Creation I think it is 18AWG, not ideal, not bad either

It’s normal for most people not to hear small differences,
(But replacing the power cord for the SC8850 is not a small difference. The original cord sucks.)

but you can definitely hear the difference between a CD player from the 1980s and a modern CD player.
The one from the 1980s will sound much better and more comfortable than the modern one.

Modern HIFI, such as CDs, amps, speakers, are all garbage.
But every year people think the sound quality is improving because they can't correctly distinguish the subtle sound quality.
Most people are just messing around, so the sound gets worse and worse.

I know why you laugh at audiophiles, they really are a bunch of idiots,
I am a music lover. I started listening to vinyl in the 1980s when I was 5 years old. I am not an audiophile.

Its pretty simple to get the proper thickness of the cable by maths.

The SC8850 takes 11Watts at 230Volts. Thats 0.04782 Ampere.
Our supplied voltage is AC. The assumed cable length is 2 Meter. The assumed loss is 3%. Assuming both ends of the cable have proper connection.

The optimal cable thickness is 0.0005mm² .

Everything above that will make no difference.

In american freedom units its the same story...

I have no idea what I’m talking about here so keep that in mind, but I think that an unshielded/uninsulated cable might be able to introduce some noise/interference on the line, but the power supply should be filtering out any noise in the power input anyway. But maybe if you had a ton of noise and interference on the line plus the filtering of the power supply wasn’t working?

If the cord is broken I would think the machine just wouldn’t work but maybe he’s having problems with a broken cord working intermittently?

Bottom line, if he likes his sound better with his new cord, that’s awesome for him even if it is just psychological.

I’d like to give him the benefit of the doubt and not just assume he’s here to sell cords. Even if he is here to sell cords, it is cool that people are making cords specifically thinking of our old equipment so I wouldn’t want to criticize him too much for that.

The SC-8850 poor sound (and "poor" being a relative term only!), at least in part, seems to be the DAC used. The SC-88/88 Pro used really quality parts (Burr Brown DACs), around the time of the 8850 Roland used some DAC's that were much more generic (more modern AKM ones). Ironically, the SC-8820 and SC-D70 both use a Burr Brown DAC and sound better (IMO).

But a power cord.. obviously isn't going to change much. I wish power cords would have such magic properties, especially on my older, noiser synths like the MT-32!

These have nothing to do with sound quality

SC8850 cannot use optical fiber cables,

Just uploaded a video, have a listen 😀
