Hello everyone,

This article was updated again to show better photo of the actual production model, I'll the better polished photo is now up.



Front angled view: as you can see the input select and gain select switch.  The rest of the layout is just like DA-152.




Front view: slightly more boring but shows the front more clearly.




Rear view: Two sets of inputs, one bypass for your other amps and systems, and one pre-out to your power amp or active speaker.



Innards view: To satisfy the pixel peepers inside all of us.   Click for large 5 mega pixel photo if you REALLY want to see the details.


Basic specs:

• High performance headphone amp with up to 250mA/channel capability. (that's a lot for most headphones in the market)
• Even better than DA-152's headphone performance, with excellent detail, neutral tone with a bit of warmth, and great smoothness.
• Two sets of selectable input for connecting to different sources.
• One set of bypass output that, well simply bypass the signal from input with no additional processing.
• One set of pre-out the is slaved to the headphone output, the test figure below shows what this puppy can do.
• Independent power supply for pre-amp and control power.  Reducing the possibility for interference.
• High performance tuned regulator for pre-amp section.
• Dimension: 215 ×205 ×80mm (W*L*H), excluding knobs and connectors

As with our products, we never shy away from posting the test figures, because well feel the figure looked quite damn good to us.   We only refrained from posting before due to design modifications that was yet to be implemented for better performance.


Only low gain setting tests are available at the moment, I'll post the high gain test result in a couple of days.

High input level test (Roughly equal to 10V RMS signal)

Click link below for the full pic.





Low input level test (Roughly equal to 2V RMS signal)

Clink link below for the full pic.



Please note the test figure above, we believe that there isn't too many headphone amp or pre-amps around that came compare. We understand that specs and test figures isn't everything, but good test figures is the foundation that can be used to create good sound.

We are still "projecting"... As well we are considering some introductory/pre-order bonuses for those who'd trust us.

[Zyca]

Well, here we are HA-171 is now ready for release

David,

Dimensiions?  This does not incorporate a DAC, is this correct?

Thanks,

Hello Jim,

You are correct, it does not include a DAC, it is a pure Headphone amp/Pre-amp.  A single function design allow us to push the performance envelop further without a massive cost increase.


PS: the first post is updated again.

Thanks

Looks like it would go great with my 131 DAC. What impedance headphones will it handle?

Hello, it will go well with most dynamic headphones, since it have way more power than most headphones would need, even AKG K1000 can be driven well without problem.


Thanks

David,

This looks really tempting. Now's the time to let us know if you are going to offer an introductory/pre-order bonus.  I would be using it with AKG 701 phones and Modwright electronics.

Well, since you've mentioned it, what about free IeGO GU-R301 upgrade for all HA-171 orders before the end of Jan 2009? To spice things up even more, if you order DA-151/131 + any of our IeGO cable with HA-171, not only will I reduce the combined shipping to $60 for the whole package (North American/Europe shipping, other region please ask, normal shipping charge is $80 for this package), I'll also upgrade the socket on DA-151/131 to GU-R301 as well.

How's that sound?

David, how much for just the HA-171? I already have two IeGO power cables (courtesy Woodsyi).

$350 + shipping, the free upgrade is not a cable, it is upgrading the IEC socket on the machine.

Is it possible to rewire it to have 2 preamp outputs instead of the bypass?

Hello David,

Yes, it is possible, I've just checked to make sure.  If you would like to order, you will need to wait for the unit to be built for you (Within 5 business days).  On the other hand, regular units are always kept in stock, so it could be shipped out usually within 1 business day.

Thanks

David

Just closing the loop on my earlier post.  I bought the HA-171.  It is beautifully made, sounds great, and was delivered to Virginia in just 4 days. Thank you David.
