Chord Electronics - Hugo 2 - The Official Thread

Yeah. It does raise the question if each ground point is different.

If each ground position were different then it would suggest the Hugo 2 would make its own ground noise. However that's why I posted and then realised I needed to add to the post. To highlight how the Groundhog can be added all over the Hugo 2 unit, or any unit. To show that it doesn't seem to matter where we ground. For assurance that whatever you do, you'll be OK.

Best just to try a DIY job. Then test different points.

With my TT2 and Shure KSE1200, I could ground anywhere and the noise went away. Even just touching the KSE1200 energiser or Hugo 2 case grounded it for me.

Ground noise comes from different units operating at different ground to each other. That shows up as a voltage difference in ground planes - between the units; and noise.

I'm probably overthinking the situation, but I wanted to get some thoughts on it.

I'm not experiencing any issues that are leading me to ground the unit. My digital source and the LPS that powers it both have a grounding post on the case and the manufacturer (Allo) recommends I tie as many of my devices to this same ground as possible. I'm not sure it'll make a discernible difference, but for <$10 in materials I figure I may as well give it a go.

Hopefully someone can help me with this. When grounding the Hugo 2 via USB using something like the "Groundhog" from iFi are you actually connecting to the ground pin on the USB input or are you connecting to the shell of the connector? I figured rather than spend $50 on the Groundhog and have a bunch of adapters I'd just make my own since micro USB connectors are cheap. I know it's possible to ground via an RCA output, but in my setup it would be much cleaner to do it via the micro USB input.

Groundhog was not made with Hugo 2 in mind I believe. It applies to several equipment and no rocket science underneath. It provides a ground to equipment that doesn’t have one. You can plug it to a RCA port, a USB port, a coaxial port, etc.
It’s a product made with someone like me ( someone that don’t have knowledge in that specific area) in mind.
I believe you can get the same results with a DIY solution.

Hi guys, tell me somebody has compared hugo2 with hugo tt. What do you say?

 

[rcoleman1]

Wrong thread.

Hi guys, tell me somebody has compared hugo2 with hugo tt. What do you say?

I have both. If I was to give up one it would be the H2. The TT is so smooth and has power in reserve which opens even easy to drive iems. Some say the H2 provides much more detail but I put that down to a bit of digital sheen and forward hi’s tuning. The TT is more analog sounding. I also have a TT2 which does provide more detail than the TT but at a big cost.

Hi guys. Trying to decide between the ER4SR or the ER4XR for my daily driver. Does the ER4SR repsond to EQ well? My main genres are Jazz, R&B, Oldies, Rock and Hip-Hop. I'm definitely not a basshead but I like a little bottom end sometimes. Thanks.

I have ER4SR, and sold er2xr,,i think the bass is adequate in er4sr. never even thought to eq them, because they already sound excellent.. just got the balanced cable and it made a huge difference.
er2xr i like the sound of the extra bass, but it did hurt my ear drums when playing too loud, so i decided to protect my ears and go with sr.

I definitely did not notice any ground noise in my model.

Well from the Chord website, the Hugo 2 uses:

Battery: 2x Rechargeable custom Enix Energies 3.7v 9.6Wh Li-ion (lithium-ion (2600mAh) batteries.

Like these:

https://cpc.farnell.com/enix-energies/mgl9015/battery-li-ion-1s1p-18650-3-7v/dp/BT06417

£17.66 each retail price including VAT.

Only customisation on the Hugo 2 version would appear to be the addition of a small plug.

Not quite plug'n'play then. Some soldering would still be required.

Frankly this battery issue is the only thing stopping me from getting a Hugo 2 same as it stops me from buying any DAP above £100.

I don't know. That page shows the MGL9015. Some Hugo 2 pics show that battery installed.

Whereas some pages show the MGL2811 in the Hugo 2, e.g.:



What confuses me though is that the Hugo 2 uses a tiny connector, to attach the battery. Whereas every pic online shows the battery soldered.

We can buy those tiny plugs though.

I searched Hugo 2 battery and clicked on 'images'.

That pic is the original Hugo

Well spotted. It even says 26K taps and I missed that too.

This one is the Hugo 2 though, and it has the battery - MGL9015. It's not easy to see, but I can make out the numbers 9015.



However the specs on the 9015 in this picture, and one spec on the 9015 in the link above are different.

https://cpc.farnell.com/enix-energies/mgl9015/battery-li-ion-1s1p-18650-3-7v/dp/BT06417

The battery in the picture says: Nominal Capacity 2.6 amp hours.
While the Farnell one says: Nominal Capacity 1.6 amp hours.

So is it good to let the Hugo 2 drain fully on occasion and then give it a full charge? Just wondering what the best practices are for maximum battery lastability.

 

[GreenBow]

Then there's this battery too. I saw some like these yesterday, and will post the link when I find it again.

Well if you look up the batteries that people have posted. You will see that sort of advice.

One thing I picked up was. It seems best to make sure you charge or discharge the batteries a minimum of once every three months.

There was another spec I saw but I didn't know what it meant. It was talking about trickle charge and said 'two years'.

Yeah this one, which might be a fit for Hugo 2 also. It might be the one on the picture of the Hugo 2 in the HiFi Choice review.

It gives some care statistics.

https://pro.enix-energies.com/media/pdf/ACL0004_UK.pdf

Shelf life with trickle charge - 2 years.
Charge frequency during storage - 3 months.
