Chord Hugo - Page 198

post #2956 of 14305

Just fired up my new Hugo for the first time last night.  All I can say is  Wow . . . just . . . Wow.

 

I have always loved my ALO Rx Mk3-B+ as a portable amp, so I hooked it up to the Hugo to see what it would do. It worked fine but added nothing. The Hugo actually did better without it and had more than enough power to drive my 600 ohm DT880's to levels far beyond what the ALO amp could accomplish.

There are more than 60 pages of discussions in the Audio GD Master 7 thread on how to pair up Master & with OR5 or AP1/PP , and getting BNC or IIS to Master &. The main reason being that the headfiers found that the USB 32 in Master 7, though very good on it's own , is lesser when compared with BNC or IIS input . How do you find it with Hugo? Do you think using OR5 / AP1 surpass the HD USB input of Hugo?

 

BTW, can anyone compare Master 7 and Hugo ?

Made up for you mate it's a great little device

Might be embarrassing putting the Hugo with the likes of Arcam and monitor audio but it sounds ace in my kitchen,sonic bliss

Might take a pair of my chord anthem aray from my 7.1 system in the lounge and see if it sounds even better,probably over kill for the Arcam,Mrs giving me funny looks so I'll leave it for now

No problem for the Hugo to handshake and decode hi-res data from the source as long as the ground is connected.

 

I can confirm that too, I am currently using usb cables that either has the +5V line (red) cut or the +5V contact point taped up (so no connection) without any problem at all. After all Hugo doesn't use the +5V (red) at all.

SeeTeeYou... site is in Chinese, can this WM-Port/Mini-USB lead be used directly by ZX1 as a music source into Hugo?... can you find out for me please.

 

at present you have to use two cables to connect ZX1 to Hugo... using a single cable would be absolutely spiffing.

We all trust Rob Watts, of course.  Here is Rob's exact wording:

"It still does not draw power from the USB, merely senses that the VBUS 5v is attached. If it sees that, then the FPGA turns on the HD USB chip PSU, then the USB starts working.

 

The benefit is if the HD USB is not connected, then the battery life is increased as the power draw from the USB chip is significant.

 

The 5v sense is isolated via a 9K1 resistor, so RF noise on the USB VBUS 5v is not coupled into Hugo and we have tested that RF noise doesn't change the SQ.

 

No you can't trick it - once VBUS power is gone, it will shut down the USB chip immediately!"

 

So I continue to remain dumbfounded at you guys' reports of using powerless USB (and your reports aren't the only ones; a couple folks on CA are saying the same thing)......yet...I asked Rob the question because I have a USB card (JCAT) that can truly turn off the complete power (top port of dual port card is configured powerless)..and the Hugo does not see it until I turn the power on (i.e use the bottom powered port I configured).  ??  Qute EX and HD work fine off top powerless port, as do other DACs not requiring 5V.  Weird.  Maybe your cables (cut or taped over) still send something enough for the resistor to switch it on...maybe ground is all it needs?  My card sends nothing, zip.  And it's blackness in that mode is why I want to use the top port. 

 

Hugo sounds exquisite anyway.  :)

No idea why your one doesn't work. Normally it is the ground (black) wire that is used to detect the device rather than the +5V. I have 2 cables that either has the whole +5V (red) wire removed (i.e no red wire in the cable) or cut off at the USB A end and 2 cables with the +5V contact point taped up, all those without any problem. I think holeout solder his own usb cables and the +5V wire isn't connected. Thus no idea why yours didn't work. BTW did you cut the red wire or alternatively which contact point did you taped up?

 

PS. when you said turning off via JCat, does that mean the whole power (both the +5V and the ground) are turned off? If that is the case, then your PC would not detect Hugo because it needs the ground wire to function.

I have a Meridian Explorer now. It's a great little device. How much an improvement would Hugo be over it? I don't have the necessarry funds right now but I'll have soon. I just don't wanna pay for 1% better sound. :)

If your question is toward me, I don't cut up my wires.  They are not the issue.  I am trying to explain that my SOURCE (JCAT USB card) does not have USB power if I don't want it to.  Yours does...hence it is sending something to the Hugo to turn on the receiver.  My approach is to have a powerless USB source.  The EX and HD love that approach...it is such a lower noise floor.  I was hoping to use the same for the Hugo.  But Rob assures me the 5V noise is not getting into the DAC so I am ok about it.  But I am not about to cut up my JCAT or Total DAC or PPA USB wires.  And I have DACs (like Meitner) that require 5V anyway.

post #2969 of 14305

I think the idea is that the +5V causes internal interference in the usb cable itself even when it isn't used (it still creating a charge). 

 

I wonder whether your JCat shut off both +5V and the ground? Hugo does need the ground wire. 

 

You could just tape up your usb cable (or a cheap one if you like) and see does it works or not. It will not harm your cable and can be removed easily if you change your mind.
