SimpleBest PSU/chassis for RPI4

[FredA]

I bought the simplebest filter and am enjoying it.

Certainly a very inexpensive piece of equipment considering how dramatically it effects the sonics.

I definitely need more time to experiment with this new toy but one thing is immediately clear: The more components I connect to the "-70dcb" outlets the more transparent the outcome and the leaner the sound. The less I connect to it the less transparent the sound and the meatier the sound. "-50dcb" has the exact same effect as the "-70dcb"- just less so. Combining use of both -70dcb and -50 dcb with different components results in transparency somewhere in the middle. It is all a matter for more or less of the same thing IMHO.

I could see how one may not want all their components hooked up to the "-70dcb" as even though it results in hyper transparency, things are pretty lean. It is a matter of balance. I have no idea where I will end up yet as I need to give my ears time to adjust to all the options.

At minimum I for certain like my mac mini plugged into the "-70dcb" even if none of my other components are plugged into the filter at all---- and just for my mac mini this filter was worth the money for the sonic improvement.

I would not put an audio-gd gear on the filtered sockets. But a computer or a clock, no issue in my experience. I prefer an isolation transfo, a big one, for audio-gd.

I really preferred my DI20HE direct-to-wall (haven't tried a high-current bank)
makes me think all HE models may be the same

So far- I like all my equipment (except mac mini which I like in the -70dcb outlet) plugged into this outlet called "direct". The sound remains meaty and dynamic- but clearer than to the wall without becoming lean at all.

I do not understand what "direct" does- but this is what the company told me:

Dear Steven,
Thank you for your reply and your comments. The ' direct' means that the 'direct' charge will block the direct-current in the alternating current. The direct charge will be suitable for back stage power amplifier if you are going to this charge. If you have any questions, feel free to tell me and I am happy to answer that Hope you have a nice day! Thanks again.

Direct is without filtering, straight to the wall.

 

[rsbrsvp]

Direct is without filtering, straight to the wall.

That is what I thought initially as it sounds very similar to direct to the wall- but it still sounds a bit clearer than direct to the wall in my comparisons.

The explanation they gave me certainly sounds like something is being blocked with this outlet.

Perhaps it is a placebo effect- but I hear a small difference...

 

[FredA]

Perhaps. The description is not under the right section.it’s found under -50dB..

there are 4 types: -50dB, -70dB, bypass (direct), dc blocking

 

[rsbrsvp]

I agree with that in regards to the website.

But their response to me again reads:

The thing is the person answering is not the designer. There must have been a miscommunication. The person is describing the dc-blocking in the answer.

 

[rsbrsvp]

perhaps....

 

[FredA]

Going through the box can have an effect on sound. Power cables do.

 

[rsbrsvp]

Indeed- If "Direct" is "bypass"- It nevertheless sounds a bit different and better IMHO

 

[FredA]

I have tried many power distributors. They all sound differently, like power cables. Being an audiophile is living on a never-ending quest.

The ' direct' means that the 'direct' charge will block the direct-current in the alternating current.

Sounds to me that "Direct" here means filtering DC noise or DC component from the AC power. Quite a few power conditioners do that, too.

No. These are labeled Dc-Block. See the image of the unit there. Note that the webpage documentation has errors in it.

Got it.
