If you are referring to the output stage, it is driven by opamps.

Do you happen to have a specific model of the Opamps and it spec? I wonder if we can use the. Output in the back for a headphones out ...lol

I don't have the opamp spec.  I was going by a high resolution image I found but the numbers can't be read.

when increasing or decreasing the sound, music, sizzles. This is normal?

 

[OhMyGodPancakes]

Yes, it's a known flaw

Try cleaning your volume pot with deoxit.

It was mentioned here not to use deoxit on this type of closed pot but I bet some have. You can get into the OPPO with a little effort.
I did use deoxit gold on the internal connectors with a nice boost to sound.

The Volume pot can be fixed normally by turning off the unit. Then running the volume knob backwards and forwards fully for a minute that should clean up the pot contacts. If the pot is faulty an nice email to OPPO is always worth a try...

Good luck

Would HA-1 be a good match with HD 800?

I quite like the hd800 using the high gain setting. I don't find the digital glare that some have described from the sabre Dac. I also use my lcd-XC with it.

Thanks!

I wonder if I should replace my Asgard 2 / Bifrost combo with HA-1 to be used with HD 800. Can get HA-1 for $745.

How about with Deckard?

My experience with the 800's is minimal but prior to me purchasing with ha-1 I tried the deckard with lcd-xc and senn hd700's and liked the ha-1 more.
Also quite few people have stated in this thread previously in their opinion the 800's go well with the ha-1, so by all means read back in this thread.

anyone here had tried comparing between this one and questyle cma600i?
thanks?

My HA-1 has powered off by itself twice today during playback. I press the power button to turn it back on and it resumes as normal. Has anyone else experienced this or have a clue what the problem is?

I too love my HA 1 for my HD 650 & HD 800S! I too have read about people discussing Sabre glare....which I just don't hear....I have thought about trying a Schiit Gumby in place of the DAC while using the HA1's Class A amp.

I made my own 20ft cable with the balanced connections and the Amp has plenty of juice for my 300ohm HP's.

I have not had any turn-off issues as noted above. Mine is less than a year old and Oppo's discontinued selling them makes me wonder about their reliability. Mine has been rock-steady and if I had to complain, it takes about an hour before it sounds good/warms up. Typical of digital gear though.

I really like the remote and the different screens the unit has as opposed to DAC/Amps that show zero information.

Cheers,
Larry

Never had such an issue. Might be worthwhile to drop an email to OPPO.

Did you unplug the headphone cable right before it powered off? I've had the same thing happen a few times over the past two years and if my memory serves correctly, it was right after the headphones were disconnected.
