New Head-Fier
Quick search am i correct £500 for a audio quest optical cable, wow £10 cable will do its digital i'm sure even Robb Watts would agree.
curious, does the grounding cable plug direct to wall socket? I use iFi AC purifier, which has a ground socket (takes banana plug) , I have a ground from RCA shield between Qutest and amp to the iFi. sounds fine, though hard to tell the difference when ground lead removed.So since I have the Qutest I had a problem with powering it. The stock psu is a EMI/RFI generating monster, like all swithing power supplies. Noise was coming through my PC, monitors, amp and even headphone wires. No idea if this extra noise has any effect on sound or not, but for me it was annoying. Powering directly from PC's usb port everything was silent. Didn't have this issue with DAVE, everything was silent. I see some had some complaints on the TT2 forum aswell with feeling tingling by touching the case.
I got an Ifi iPower 5v to see if its better then the stock psu, but it had the same noise. I even considered buying a hifi pci e card to power Qutest, since this issue bothered me so much.
Even the power bank battery had EMI/RFI injected into Qutest. Until, by random testing, I introduced the battery with charing usb to PC's port, and behold, all the noise was gone. I guess it all went to the ground. That got me thinking that if I can somehow ground Qutest all the noise will go away.
And I've found the solution, it's called iFi Audio- Groundhog. Connected to the Ifi iPower 5v all the EMI/RFI is gone. Everything is silent as it was with DAVE. Don't know if this will work with stock PSU, needs an adapter, or if this will also work with TT2.
Such a cheap solution to a problem that I don't know if it affects sound quality or not, but for me it was bothersome. Will attach a picture to see how its connected, Ifi iPower 5v comes with an adapter DC jack to micro, the groundhog is between DC in and the adapter.
must be real diamond fibre in there in there for that price..Quick search am i correct £500 for a audio quest optical cable, wow £10 cable will do its digital i'm sure even Robb Watts would agree.
IMO Audioquest is waaay over priced!must be real diamond fibre in there in there for that price..
though was a shame they moved out o the headphone market, the Nighthawk's great sounding and against the competition not overpriced. Maybe they weren't making big enough profits on them..IMO Audioquest is waaay over priced!
I've been using an Anker power bank rated at some 26800mah. It sounds great, no noise or interference at all. I actually tried a cheaper batter back and noticed the highs started to bother me. Switched back to the Anker and it has been sounding perfect. It also lasts a really long time. I just unplug it from the battery side when I'm done using it. Will last me several days before I need to recharge it.So since I have the Qutest I had a problem with powering it. The stock psu is a EMI/RFI generating monster, like all swithing power supplies.

Glad to hear youve found the optical that suits your listening style. I was in the same boat tossing out the usb for optical, but it was a lifatec glass toslink. I wonder how the lifatec compared to the diamond toslink in terms of music character. Please do a comparison if you have the time/cable. Thanks
It was around €120 for me and it was well worth!I'm sorry, unfortunately it's very difficult to buy Lifatec in Europe, that's the reason I went with Audioquest..
Useful info on the QED. I'm now thinking about moving to a glass cable as well, current cheap plastic one gives no issues, but if there's gains to be made then of course would like to try. Yes seems the Lifatec only available in US, so I'm not sure what else to go for as the price of the Lifetac would be about the most I'd be happy spending.I'm sorry, unfortunately it's very difficult to buy Lifatec in Europe, that's the reason I went with Audioquest. The only glass cable I had was a glass QED and that one was very bright, almost usb like, so if your current cable is softer sounding then usb with no veil added then it should be close to Diamond Optical, but again, its different for everyone, all you can do is test for yourself and see if its worth it.
