I'm looking at this too. Besides my cd collection I have maybe 6 "high resolution" downloads from HD Tracks burned to dvd that I listen too via Oppo 105-optical-Ha-1-LCD XC. I have very good hearing but can't really tell the difference between the 24 bit stuff and well recorded cd's. Tired of...

Whatever takes a boatload of talent to play. I listen to classical, contemporary jazz but mainly focus on strings like Strunz and Farrah and Acoustic Alchemy. With my Ha 1 and Audeze you can really tell the difference between poorly recorded and excellently engineered music.

I have both. The HA-1 is a lot stronger. I have the Audeze LCD XC and not only does the HA 1 have more power for whatever reason it also sounds better. Tiny details hidden in the mix are clearer. Oppo knows just where the point of diminishing returns is and I'm very happy with mine.

Because of space restraints mine is sitting directly on top of my 105 which itself puts out heat so I thought it prudent to have a little air blowing between and over from a near silent fan. I wont hear it with my Audeze lcd xc closed back phones unless it makes a buzz electrically in which case...

Wow. Color me impressed. Much the sonic signature of the 105 headphone out but more power and finer detail. I'm definitely hearing subtle background things in recordings that were faint or inaudible before. Has a decisive  ( analytical? ) resolution that may not appeal to the warm/fuzzy crowd...

Arrives today:D

Mine will be powering an Audeze as well ( lcd xc ) :D I like the no metal connection optical idea. Just dont know if it will pass 24 bit. Guess ill find out.

I guess I should have added the 105 is powering my home theater and I use it directly to an amp utilizing the 105's onboard volume control which I will turn all the way down. That also keeps the signal sensor in the subwoofer from turning it on. So for now at least I need to use the digital out...

Just bought a refurb HA 1 and plan on feeding it with a digital coaxial/optical cable from my Oppo 105. I have a small collection of 24 bit flac/wav files burned to disc and was wondering if they'll work that way. I have a Android tablet but have never tried computer audio. Not sure i want too...

I dont know what that is. I have a 8.9 Kindle hdx but dont see anything about a otg.

So when's the front usb port going to be compatible with android?

How about the front usb port supporting Android?

Oppo inputs don't support lossless sound?

Smarty,  How are you connecting your 105 to the HA-1? Coax? Optical? Have you done a close AB between the 105 and HA-1 headphone outputs? I'm not trying to talk myself into buying one, honest.   ARRRRGGG!!

I didn't expect Oppo do do anything of the sort. No manufacturer would. Just wish I had a crystal ball some times and I'm sure I'm not the only one who spends more money than they should on shiny new toys like these.:D

Ok Smarty-britches, If I'd have KNOWN Oppo was building this kick-ass HA, I WOULD have bought the 103 instead of the 105. But NO!!!! these things must be kept under wraps don't they!!

But then again I loaded my high rez recordings along side the cd's already there and it took up half the space of the measly 64gb storage on the tablet. Maybe a laptop is in my future after all. That AND the HA-1 will by expensive tho'.

    I have the lcd xc into a 105 that sounds excellent. I was going the get the HA-1 until the front port issue came up. the front port on my 105 plays my tablet, thumb drives, whatever. maybe the HA-2 will be more accomodating. ( Is Oppo reading this? )

And why does the front usb support iPods but nothing else. :confused:

I don't get it either. Wouldn't you want a micro usb to full size male usb to run a kindle or other android into the front usb port of the ha 1?

Will the front usb port ever accept android?

So aside for more power the HA-1 sounds pretty much like the headphone amp in the 105?
