Which one to buy: UpTone USB REGEN or Intona USB Isolator?

My effort, ....I was lucky as I had a small enough Allen key to remove the PCB.

 

I ESD strapped and out into an ESD bag for safety...

 

Did slice myself a few times. ... There is a void sticker on one screw so be warned.

 

I wonder if ( Is it Daniel? ) @ Intona could test this... Give us all his thoughts... they designed it... Jplay made it look like deaths Ferrari...

 

Have fun

Hi,

Could explain more about ESD strapped

How to do it? I just only wraped it.

Thanks

[NAIDIVER]

Sorry NAIDIVER

ESD is Electrostatic Sensitive Devises.

 

You can damage electronics with static so I am always careful and earth myself. I use a strap...

Can you show me some photos of yours (with intona)

[NAIDIVER]

Hi NAIDIVER..... I only use ESD strap to remove electronics before fitting tape.

The strap isn't used with the INTONA....

 

?

ha ha ha... I still don' t know what it is anyway...

Ok.. I will learn it from your given link.

Thanks, Middy ^^

Today I should receive my Intona. I have a question... Does the linear psu for the computer still make sense with this product?

Theoretically I would say no.

 

I don't know much technicly and theoretically but from my trail and test.

Intona is not a universal drug for the whole deceases.

You do still need a LPSU for pc.

I use PPA USB card with separated LPSU and ATX LPSU for pc and also with ac line conditioner.

But i can hear the diffence. Intona with clean signal from audiophile pc sounds better than regular pc.

 

If it doesn't make sense. The sound should be the same.

" What??? "

 

[NAIDIVER]

Not what but what what with watts...What...

 

Jplay stole our idea by making it a custom great looking case... I draw the line if J Play bring out their brand of kitchen foil.... Not for the microwaves though.....?

 

I just got my MU metal but I am waiting to try it on a new toy when it comes before using it on the Intona. Abtr great find on the case may be enough but as it's a test... that hopefully will benefit others.. pushing the limits doesn't hurt...

 

Keep smiling

Ha Ha Ha , I love your comments.

Fwiw, I'd say that if the audible effect of shielding the Intona is about 20% of total computer (usb) audio quality, then shielding the Aqvox may add another 5 to 10%. I didn't do any blind testing though. And I still have to try copper tape.

 

Hi, Abtr

I heard many friends on here used copper tape for shieding. It made me wonder why. because as i know, Aluminium is better for shielding. Or i misunderstood? not sure. Sorry.

 

[NAIDIVER]

I have placed a Bybee Signal Enhancer underneath the Intona and a project case filled with steel BB shot on top of it. Very nice improvement.

 

Hi, What is a Bybee Signal Enhancer?

[NAIDIVER]

You guys are all nuts and I say that with much affection. I totally get a kick out of reading about all your trials and tribulations with widgets and widget tweaks. I wish I had the energy and will (and money) to partake.

 

Hey.... It's fun!!

For me, It's funnier than washing dishes for my wife at least.

Hi NAIDIVER,

 

I think basically aluminum should be almost as effective as copper for shielding high EM frequencies because of its high conductivity. For lower frequencies (below 100 KHz) copper is said to be better, although the aluminum case is much thicker (1.5 mm) than the copper tape that I ordered (0.1 mm), so I'm not sure if the copper tape will make a difference. I'm thinking of buying an EMF meter to do some measurements.

 

A problem with aluminum (as was already mentioned by John Swenson) is that the surface will always be oxidized and aluminum oxide is an insulator (also see your graph above). This may compromise the electrical connection between the lid and the rest of the aluminum case so it won't act as one continuous shield. The copper tape I ordered has a conductive adhesive. Applying it to the outside of the aluminum case directly after sanding off the oxide should effectively seal it and fully connect the two aluminum parts..

 

Hi, Abtr

I don't understand that chart much.

I thought i have to see it insulator index. Is it wrong?

Is your computer connected by a 3 pin IEC mains socket to mains earth ?

If so, the screen connection of the Intona's incoming USB socket is likely to be connected to mains earth. You should be able to verify this using a DMM.

If it is, try connecting the metal work of the USB socket to the metal case.

Hi, Alex

I also used EMI absorber sheet. Do i have to do the same?

I meant is it grounding necessary?

 

And second question, does it cause short circuit if it contact to any paths of circuit?

[NAIDIVER]

Check first if the metal shell of the incoming USB socket on the Intona is connected to earth when connected to your computer.

You can also do this by measuring the resistance between mains earth and the metal shell of the USB plug at the output end of the USB cable from the computer. You should only read a few ohms resistance if it is.

You don't need to touch the EMI absorber sheet.

Before doing this, check that there is no measurable resistance between either the Input or Output USB socket shells and the metal case due to how you have mounted it in the case.

 

For the absorber sheet, i didn't applied it for intona but my pc. Just ask for the information. ^^

Is it ferrite or something?

Can it cause short circuit on my pc?

Thanks....

Easy to say, but hard to prove. Not all galvanic isolation is equal. I wouldn't trust what the manufacturer claims.

 

Agree. My Brooklyn DAC also Galvanic isolation built in. SQ is still improved after Intona connected inbetween.
