What would be the point? The biggest part of the cost of a component is the casework. The circuit and socket for the headphone amp is only a small part of the cost. Removing it won't make the product significantly cheaper.

 
I was thinking about those who want a quality DSD DAC without all the extras.  Actually, have a base model without any of the add-ons.  Can you post how much the casework and circuit parts costs?  I'm not aware of the prices.

Most of the analogue circuitry used to drive the headphones is also used to drive the RCA and XLR outputs too. Only the final output buffer could actually be removed along with the headphone sockets.

They already have that---AMR DP777.

But that does not have DSD capability, right?
I thought it does, but checking AMR website it seems you're right. Well, now I'm really waiting for that mini iDSD!...:D

Including a HP amp wouldn't hurt. In fact I think that's better (vs external HP amp) because you got a much shorter signal path.

AMR has released an upgrade for their DAC. It allows one to listen to native DSD as well as improves other aspects of an already popular design.

Great to know that. Thanks for the info. Cheers.

  Hi all,

Major case of feature creep - so we are going to aim for prototype for CES and then launch in Mar.


 
When we have anything close to soup, we'll put it up here.


 
The next new product is the Retro and that is coming in November.


 
Okay, not fully soup, but here you go as we're in a good mood today!

Cheers.


I saw the real pieces of both Mini and Retro in a event at the AV Fair in Guangzhou, China.  I like their designs and specs as well as the materials that they use for Retro's case and speaker boxes (are made by bamboo). In particular, the sound quality of Retro (can't test the mini yet) is so sweet and powerful given that the small size. I enclose few pics of Retro I took at the AV Fair for your reference. iFi will launch Retro in Europe first, follow by the USA and Asia. I can't wait to have one

What is iFi retro? What does it do?
