Oppo has re-opened the store for the HA-1, so go run and get a unit before this batch is gone. :ksc75smile:

Not much of a review. I sure wouldn't run to the "Add to cart" button based on it. As far as musical impressions go this is about all he had to say:

 I played music, mostly classical, from my iPod and also from my computer, where I stored the downloaded DSD128 music files. All of it just sounded terrific! The highs were clean, and the bass was deep. No excessive sibilance or congestion in the midrange.

My setups will have the HA-1 in my office and the 105 in my media room... the best of both worlds.
I don't often listen with headphones in the media room though, but when I need to it's nice to have the 105 for that.

 

I am surprised there is only a slight difference. Based on what I can see from the design, it should be a significant difference, particularly with a much more potent amplifier stage. The BDP-105 sells for a similar price to the HA-1 but of course includes much much more. The HA-1 is specifically focused on the headphone amplifier stage, and a slight difference would be seen as pretty much condemning it as a failure! (I don't believe that for one minute though). With more demanding headphones like the Audeze LCD-2/3, the BDP-105 simply didn't have enough oomph and so the result was that some of the dynamics were lost. It was a clean, neutral sound however....just not as involving as it could have been.

 

Resurrecting a post from someone else above that never got answered. In terms of power output comparisons. The Burson Soloist is rated at 4W per channel into 16 ohms (single ended only). But they don't say anywhere whether that's max, RMS or rated power output. So I am struggling to know how it truly compares in output to the HA-1. Audeze recommend 1W per channel RMS into 50ohms for an LCD-2 for example.

Some others have said a bit more than a slight difference. Just depends on your own setup.
Yes you get other features with their pre-amp media players (BDP-105 and BDP-105D),
but you are not realizing all of the features in the HA-1 that are not in the players, so it's more like trading one set of features for another set of features.
Yes the 105 could have a bit of trouble powering the most difficult to drive headphones, and that is just one feature that the HA-1 improves on.

Lots of talk about the HP section of the HA-1 but, unless I missed something, not much about the DAC's sound characteristics.

 

If the DAC is no better than the 105's then, to me, this is a case of product redundancy. All Oppo needed to do would have been to include a top notch HP section in the 105. Even with a slight price increase it would have become the ultimate no-brainer.

Indeed. We need some more details

 

Firstly, the ESS9018 can be used as an 8 channel DAC. In fact on the 105 I believe that is exactly how it is used. I seem to recall 4 of the feeds are used for the stereo output, 2 are not connected, and 2 are used for the headphone out. But to get the maximum SNR and dynamic performance you use 4 DACs per channel. Based on the specification of the dynamic range for the HA-1 in the DAC stage (115dB), this would indicate to me they are not using 4 DACs per channel and have probably split it again to cover the pre-amp output.

 

Secondly, there are the choices of op-amp and capacitors as well as the power supply aspect that all affect things. I don't believe we have enough data to judge that either at this point.

Not really. The BDP-105 would have to be slightly redesigned to add more. The HA-1 takes 2-ch audio quality step further and has a little better sound (to my ears), and others say even a bit more.
The HA-1 also has features the -105 does not... analog inputs, balanced HP output, trigger in/out, bluetooth, mobile direct connect, low/high gain, HT passthrough, DSD256, volume knob, and more...
Just as well, not everyone wants a big media player as a desktop HP amp. The HA-1 is much more compact for table side, bedroom, or office type setups.

Additionally, in my experience, Bluray players are generally tuned for speaker setups. The HA-1 was designed with headphones in mind, not home theater...

I understand, and I suppose not everybody is looking for the same features/sound characteristics. That being said, based on Oppo's VFM track record, I had high hopes for the HA-1 as a DAC but until I've read enough comments/reviews to convince me that it is not yet another hyper-detailed but cold sounding analytical ESS based DAC I'll hold off.

 

As me and my ears get older I find myself longing more and more for that rich, meaty sound my memory associates with vintage gear.

Kind of sort of, yes.
The pre-amp/media player/dac (BDP-105(D)) puts emphasis on home theater setups and includes a very nice headphone amp.
The headphone amp/pre-amp/dac (HA-1) puts emphasis on headphonics and includes pre-amp features.
So you choose which is best for you based on what you need. There are actually quite a few people so far saying they have both, because they like them so much.
I also have both, and use the -105D in my media/theater room, and the HA-1 in my office where I spend many hours at the pc for work and play.

Having got both units myself now, I can safely say with headphones like the HD800 or LCD-3, that the difference between the BDP-105 headphone output and the HA-1 is significant. There is a really obvious difference between the two. The main difference is the dynamics. The BDP-105 output makes the sound feel compressed in comparison to the HA-1. This is what I would have expected and I can now confirm it. There is a slightly brighter tone to the HA-1 as well, but the main difference is a significant and obvious difference in dynamics. While the tone is slightly brighter on the HA-1 than the BDP-105, it is slightly less forward in the treble than the Burson Soloist. This makes the HA-1 extremely successful with the HD800s...and a matter of preference for a darker headphone like the LCD-3.

I seriously doubt you'd want a class A amp running in your blu ray player next to your other gear or in a rack. The HA-1 gets class A hot!

Also keep in mind that it is fully analog and balanced throughout which uses double the space. It would have to be that much bigger to accommodate a media transport and the associated inputs/outputs for home theatre. At the end of the day a BDP-105/HA-1 hybrid would be as big or bigger than most home theatre receivers and very difficult to keep cool. Imagine the issues introduced with cooling fans and space dedicated to heat sinks. Not going to happen.

For the markets they are intended for each device is top notch. Don't forget about the superb video processing in the 105. That is one of the main selling points of the player, which it really is at the end of the day, a media player. The HA-1 is focused in being a headphone amplifier/pre amplifier with a suburb DAC implementation.
