We also spent a lot of time comparing whole unit combos :-


Oppo: HA-1 -> Balanced -> PM-1
Stax: Invicta -> Balanced -> Electra -> SR-007Mk1/SR-009

The Oppo setup to my ears had a closed holographic presentation whilst with the Stax it was more open sounding.

I'll spend more time listening to the HA-1 with the PM-1 balanced and unbalanced, and with other headphones tonight. And will try doing HA-1 <-> Invicta comparisons tomorrow night.
Your post is not clear.
If you used the PM-1 in this comparison then the whole impressions are flawed because of using different headphones.
Better to Use the same headphones and don't bother with PM-1.
At least can compare dacs.

Sean I noticed considerable improvement after 72 hours of burn in with the Ha-1.  Most of that treble energy and edge is gone now. Really liking the amplifier and dac for what it does in this price range. Great thing is it will drive most headphones easily .

Thx for the tip Frank, I'll see if I can let it burn longer before I pass the unit off to the next reviewer.

Listening to the HA-1 with the HD800 and it is sounding  very detailed and has plenty of power on reserve to drive them easily. Using mostly normal gain for all the headphones and having good results.

You are listening at a high level as you pointed out what I didn't realize happened to me as I was breaking it in..
The trebles did have some slight extra energy or presence,
but I did not experience it as having edge.
Maybe sparkle instead. .
Kind of highlights the details.
But it vanished and made me think I was mistaken.
Yet this Dac is definitely a top notch dac.

4 days and counting.....

Made my own "triple threat" type adapters for all my favourite phones in readiness.

Can use pretty much any phone with any cable. The PM-1 cable has balanced 4 pin XLR and 2 x 3 pin mini XLR (LCD). So made adapters for PM-1 / HE-6 / HD800.

PM-1 shown with Silver Dragon.

You might want to read this posting I just added to the Oppo PM-1 thread, because it mentions this thread.

If you haven't seen the HA-1 in person, you'll want to check this out.
It'not an official review, but just an overview with some very nice video demo shots of the HA-1.

Oppo calls its HA-1 a headphone amp, we call it pure audiophile awesomeness

OPPO had released PM-1 & HA-1 last week in HongKong and both will be available in June. You can search more news on Google.

SS burn-in. I'd give up everything I own if someone could prove this.

One of the happiest days of my life was the day I stopped worrying about it.  Audio is a really big tent, and I hope it gets bigger.  That means allowing a plethora of concepts to flow like water without bashing my head on the rocks trying to change the tide.

 

Ahhhhhhhhhh....................serenity!

 

Closer to topic- I kinda home Oppo releases separates.  I just don't need an amp/DAC combo.

Just because you haven't seen any proof does not mean you cannot hear.
Trust your ears over your eyes..

Your ears are the most complex sound receiving instruments in the world.
Combined with the brain to process much more so I would say, like in my sig, that it is you who is limiting yourself. .

Yeah, if you're in an anechonic chamber.
