And so, I was looking for a longer USB cable as I shifted my hardware around. I began googling here and there.
And so it seems like a USB cable without the 5V power (Data+/- and GND only) MAY help in the SQ as there's no noise introduced into the cable at all.
(I used 'MAY' here as I don't want to go into debate regarding digital cable )
I found Elijah Audio Isolate CU and Michael advised to do a simple test to see if my DAC can work with the 5V.
No. It didn't work.
I'm using JRMC 20 with ASIO driver. It cannot playback.
I did also emailed OPPO Service to ask them about it, below is their reply.
Any comments? Or did I do a bad job in testing? I used electrical tape to cover the 5V pin.
I tried this a while back and neither the oppo HA-1, or the schiit "wyrd" worked without that power alive.
My next idea it to reroute the power separately by using two cables.
Also they make a cable which separates the power conductor from the others internally and is shaped flat..
Hi All,
I need a little advice from all of the gurus on here...
I just purchased a Oppo HA-1 a month ago. I'm having some odd performance issues with it. The sound out of the balanced outputs (not headphone) just don't seem to preform up to par with the rca outputs. I'm connecting this to a Creek Evolution 50a and a Little Dot MK VI+. So speaker output and headphone output seem flat but seems much better with rca. I though it may be cables so I've tried some custom pure silver xlr cables(way to bright but still lack luster) off ebay and now I'm on some kimber hero xlrs, still same isisue.
How can I test if there is an issue with the XLR output? Maybe it is just the synergy between the Oppo DAC and the Evo 50a? That doesn't make a whole lot of sense since the rcs works well. If it is a synergy issue, what DAC would you replace the Oppo with?

it was stated way back in this thread that the rear connections are opamp based and take a bit of burn in and was stated to be a bit lean at first untill break in.
I haven't experienced this myself as I never used them but thought it would help to know this.
I would like to add. I own the Oppo HA-1 plus a decent tube Amp. With average tubes in it still beats the HA-1. With good tubes it runs circles around the HA-1. I often switch between the two set at the same volume and it is night and day difference. The amp section of my Oppo HA-1 is basically retired. Only use DAC and remote volume control.
ok so I know it was a bit misleading as I believe you are talking about a $2k woo wa22,
But I like to know if you were comparing with the ha1 balanced out or the single ended out.
To me the balanced out makes a considerable improvement and specs show HA-1 as the more powerful unit,
Although I see your point about the %5 improvement and the tube sound could easily give you that.
Definitely an excellent amp that woo..
