I have 3 usb cable:

Purist 30th Anniversary USB Cable 1.0m 1500$

Acoustic Revive USB Cable 1.0m 500$

hp OEM USB Cable (Printer 1.8m) 5$

 

My true Bit-Perfect system :

Roon Labs -> Macbook Pro 13 Retina 8Gig i5 -> Berkeley Alpha USB (Streamlength Code) -> AMR DP-777/EAR DAC4

 

All usb cables sound very very different but all are crap.

hp 5$ has flat sound but very easy to my ear and very balance but it is not transparent .

Acoustic Revive is very Clean and precise but the sound is mechanical and compress.

Purist is more beautiful sounding than two other but it is compress . i love purist analog cables , they are so good and i use neptune series for AC Power, Interconnect and Speaker Cable but their digital cable is compress.

you could turn volume up by hp 5$ cable but purist and AR do not let you turn the volume up.

 

I ordered Audioquest Diamond USB Cable 1.5m and i will get it before 15 october.

 

now i would like to know is any body know a good sounding USB cable without dynamic compression.

i need beautiful sound of purist without compressing dynamic .

 

before posting this thread i did read previous threads. no gain

Like quite a few others have discovered, current USB 'treatments' do work. To start, the Intona Isolator separates the computer from the DAC/DDC and the best is, it doesn't require a power supply. Any ground loop is broken with the Intona, and that is most likely causing dissatisfaction with cables you have so far used.

 

If you don't like the looks of the original plastic box product, JCat have a nice metal case, it's the same inside as the regular Intona. You need an extra USB A to USB B cable, you have no shortage. Keep the best cable towards the DAC.

Gordon Rankin do not use +5vbus in Berkeley and isolating my macbook power has no gain.

i do not blacker background with more noise filtering , i told i need dynamic.

i have iUSB 3.0 and i damaged the sound . i removed iUSB 3.0 from my chain.

direct connection of Macbook to Berkeley Alpha usb is the best way.

I second the JCAT recommendation - their product line is well put together.

 

JCAT Reference USB Cable: JCAT – reference computer audio accessories | JPLAY

The JCAT USB Isolator is also an excellent product and does make a difference.

You will observe an increase in dynamics in my opinion as it isolates the noise from your Mac;s power supply.

 

Most of all being Swiss you will not have trouble shipping to Tehran.

Isolation is a workable technique. Isolation to 4kV, this means a voltage of more than 4KV must break the barrier between input and output. IUSB does not have this specification. Intona is an isolator not a noise filter. I have used intona on 4 dacs and 2 DDC and all of them benefit.

Thank you

There are some interesting company out there like VDH , CAD , Couirus , light harmonic And ...

Light harmonic even give you eye pattern but non of those specs help us to go right directiob.

What about dynamic?

what kind of music do you like?

 

I listen to various type of music and Choosing USB cable has No relation to music , i need dynamic sound just like placing loudspeaker in a better place. More Dynamic mean you could turn up more the volume

I do not think it help , many ac filters like shynuta clean the sound but kill dynamic. Many high power solidstate amplifiers use negative feedback for less noise but they kill dynamic.

Berkeley use Gordon Rankin Streamlength code and it is very good interface. No usb input of any dac even with good isolation and noise filtering sounds as good as Berkeley.

 

I should say i compare Berkeley with our reference CEC TL0-X

How do you know that the usb cable is at fault? Have you tried other types of connections and get the sound you want?

Right question, i think about that because various usb cables sound complete different.

Hp is more dynamic but very veil , Acoustic revive is very clean and transparent but so compress.

About other component and computer setup all are configured bit perfect and we have no ground loop in system.

Most audiophiles do no care about dynamic as i mean, bad speaker placement kill dynamic but no body care it in his home

You may also wish to consider a better source and/or better power supply. I've used a MacBook Pro in the past and I can tell you from my experience that there a number of better source/power supply alternatives that will have a more significant impact on your sound quality than different USB cables. One less costly option is the Audio Alchemy DMP (digital music player). It is simple to use and produces great sound quality. Plus it uses an AES output so you avoid USB cables entirely and avoids the need for your Alpha USB converter.

You are barking up the wrong tree if your issue is dynamic compression... that's a source resolution quality issue. USB cables color, mask, irritate but unless they are utter crap dynamic compression is not fixed by a different cable. Look into solutions that will improve your output resolution into the USB cable.

The reason I asked those questions, is that sometimes people expect way too much from cables. They spend a lot of money, and when the cables don't fix the problem, they get very upset. That said, cables can make a nice difference, and if used properly, can enhance SQ.

 

You made this statement as well

 

"Many high power solidstate amplifiers use negative feedback for less noise but they kill dynamic."

 

You're exactly right. That's why I say cables may not be enough. No cable can overcome a high feedback amp that has no dynamics. Anyway, here's a few cables you may want to look at.

 

Harmonic Technology INEX Photon Digital USB

JPS Labs Superconductor V USB

Kimber Select 2426 and 2436

 

I would also recommend the AQ you have on order.

About dynamic compression:

- Room/speaker placement

- Record quality

- digital cables

- high negative feedback amplifiers

- low sensitivity speaker

 

Usb cable design is so important

high end is more complex than making product by measurment devices and it seems very few designer focused on digital cable design.

i check your list

Technologies advance. USB-B, beyond the cable, what Marantz for isolation has done :

Images found from Japanese reporting :018.jpg

Equipped also with a digital-isolator in the interior of the MMM. When using USB-B' date=' SA-10 has therefore adopted the [/u']digital-isolator at two places in total.

017.jpg

For the soon-to-be latest product, a reply from Ken Ishiwata to me regarding their SA-10 DAC / Disc Player :

« Best sound performance you can get from SA-10 is using USB-B !!! Once you listen with USB-B with good PC, then you won’t listen to anything else…. Not just sound quality but also size of sound stage and precision to stereo images are completely in another level !!!!

Yesterday in my listening room I have worked once again with Rainer Finck to come up with certain proposals for Japanese…. We will continue till we are happy with the results but one thing for sure, best performance will always be by USB-B…. »

 

Well, keep in mind to audition it when it's available in your country ; Japan release is later this month, but Europe (and America too ?), Ken said « next Spring »

Proprietary technology, we'll have to wait and study what exactly they'll reveal alongside its release. Ken said they're seeking patent...

I must need the USB isolation devises. AES, FireWire, and now Thunderbolt seem to be better solutions for connectivity in my system. May be the implementation.

I have only tried LH Labs, Oyaide, AQ, and Furutech USB cables. They do sound different.

 

2012 Mac Mini, i5 - 2.5 GHz, 16 GB RAM. SSD,  PM/PV software, Focusrite Clarett 4Pre 4 channel interface. Daysequerra M4.0X Broadcast monitor., My_Ref Evolution rev a , Klipsch La Scala II, Blue Sky Sub 12

Clarett used as ADC for vinyl rips.

Corning Optical Thunderbolt cable used to connect computer to 4Pre. Dac fed by iFi iPower and Noise Trapper isolation transformer.

I am going to try AQ diamond , CAD , Oyaide , Curious in future
