I checked the same files on the laptop and the Oppo displayed bit for bit what I was playing. I would change the bit depth and sample rate from my laptop and the Oppo kept pace and would display everything exactly as it was being fed. blink.gif

Turns out I was still on a beta FW on the DAP because I was testing sonic differences vs the official FW, and in my excitement to hear the HA-1 forgot to switch back the the official FW. rolleyes.gif

Long story made short, the DAP was down sampling in the beta FW and the HA-1 caught it. I'm confident it's bit for bit, no conversion, up / down sampling here. cool.gif

Thanks for that!

Unfortunately that is really above my paygrade, so I really do not have an answer for you. You may want to hit up our E-Mail support whom can forward the request to the engineering group for a proper explanation of how the ESS Sabre32 chipsets are utilized in the HA-1.

Thank You Hastur for your help, but why don't you ask directly to your engineers? After all you have a direct contact with them.

A request from a customer usually holds more weight, importance, and usually actually answers the question than if I made the request direct. My job at OPPO is conflict resolution (ie. Tech Support), so my main concern is to isolate and resolve issues. My knowledge and understanding just needs to be "in good faith", that is, I just need to know that is is supposed to work, but not necessarily why it works. For a customer, "good faith" isn't necessarily enough, so the engineers will take an extra step to discuss the technology and its implementation when they know that the request is explicitly for a customer, rather than for personal curiosity/reference. This is why I always recommend that customers send a written request when there is something that can't be answered directly on the forums or when engaging in a phone conversation.

 

With that said, I have already made a request for a response about how the ESS handles internal upsampling, but since this is the weekend, I do not know when a response will be tendered.

We all apreciate! 

Thanks again for your help, Hastur.

"Under promise; over deliver" and "expect the unexpected". 

There will always be inherent limitations in the hardware/software, so it is best to take suggestions as they come, work on implementing them to the best of your ability, then release the enhancements to the customer.

Can you confirm whether a simple bass & treble control feature will be added or not some time soon?

Want EQ?  Connect your Sanza Clip to the RCA inputs of the HA-1.

Here yah go, the unofficial announcement

http://www.amazon.com/s/ref=sr_nr_n_4?rh=n%3A172282%2Ck%3AEqualizer&keywords=Equalizer&ie=UTF8&qid=1400423975&rnid=2941120011

... Buy two HA-1 and use one as a dac to reduce any interference between the dac and headphone components. Just insert desired EQ of choice into chain and there you go, problem solved!

When will it be released in Europe ?

post #268 of 4750

Will there by 230V versions?

post #269 of 4750

For anyone lucky enough to have obtained an HA-1, I have three questions:

 

(1) Is it possible to disable the headphone amp section while using the preamp outs? (This seems important to me, given the Class A operation of the headphone section.)

 

(2) If you've been so brave as to take the cover off your HA-1 to peek under the hood, can you see what devices are powering the preamp outs? Reportedly, the preamp out stage using op-amps, but I'm wondering both (a) whether this is accurate and, if so, (b) what type of op amps are used.

 

(3) In some photos of the internals of the HA-1, the big capacitors appear to be made by Su'scon. Confirmed?

 

Thanks!

1) No. The headphone amp stays on when using the analog outputs, instead of headphones - it can't be turned off without turning off the entire HA-1.
