Folks, RMAF!
Amazing show, amazing vibe, amazing visitors, amazing hardware! And we're there!



Many of our products are to be found at our place, including the full Pro stack (Pro iESL + Pro iCAN + Pro iDSD) and a number of fabulous headphones; Focal Utopia, Final D8000 etc.



And we have something very special in there too! The latest AMR DAC. For now we'll just put these pictures here, but in upcoming weeks we'll reveal more nfo about this machine!

 

[captainobvious]

what is the correct size DC power plug required for the DC input socket on this unit please?

 

[ShinRA88]

Do you have updates on pentaconn made by order version?

Ugh I wish mine had a 4.4mm instead of the 2.5. Bump as this needs to be addressed!

We see those comments. We really do

 

[all300b]

Can we ask general questions about the upcoming AMR DAC? Did you custom craft the world's first 32-bit R2R silicon? What about 3D printing your own customized version of the Bendix 6900 for the output stage? Expecting great things from this one.

It looks quite sad and lame with the 4.4 to 2.5 mm adapter ( and i don't think its good for the socket over a long period of time)

 

[doggiehowser]

I use a Heimdahl2 adaptor - 2.5mm to 4 pin XLR. You can get longer ones as needed.

I am subscribing to the "The shorter the adapter.. the better." theory

 

[doggiehowser]

With some cables, not always true - there is an optimal length, and they often sell it in multiples of this length. So a Nordost 1m cable may be 1.05m long for one model and 1.03m long for another.

The best is no adaptor at all. But I think the full Heimdahl loom seems to work well

Soon we'll do something regarding explaining what this product is and what it does. Stay tuned!

1. DSD Remaster mode works with filters, therefore yes.
2. We'll explain how MQA interacts with filters once this functionality is added.
3. We're working on this and are almost done.

@iFi audio “Almost done” with MQA Release sounds confident. Are you confident enough to commit to release this within 2018?

We're confident in saying that it's almost done. When we know the exact launch date, we'll inform everyone here.

I take that as a “no confirmation for 2018” then.. boo! The cadilllac-style “lamborghini AMR dac” should wait, let’s get Pro iDSD completed just kidding, how could complain while listening in joy to the Pro iDSD. Complete joy

Jaw-dropping features - the story ends

Power Supplies

Using classic tube design, brought up-to-date with 21st Century technology, all incoming DC is converted to a high-frequency waveform then rectified and filtered by a choke input capacitor filter. This produces a first-level DC bus from which all further voltages are derived. The circuit also generates a galvanically-isolated power supply voltage for the USB input circuitry.

The digital section is powered by a bank of Super Capacitors totaling 6.6 Farad (6,600,000uF). iFi uses Elna Dynacap DZ (TM) Super capacitors because they have a 400 times lower internal impedance than common grades of super capacitors.

Individual low-noise TI LDO Regulators with local LC filtering provide the final low-noise power for all individual digital sections, a total of six individual regulators cover Clock, SPDIF Input and the DAC's digital section.

For the analogue stage (especially the tubes) higher voltages are needed. The whole stage effectively operates on a 60V rail offering massive potential dynamic range.

The USB input section has its own separate power management system with multiple regulators and filtering operating from the galvanically-isolated voltage generated to power this section.



For the analogue stage, higher voltages (especially for the tubes) are needed. The whole analogue stage in effect, operates on 60V rail, giving massive potential dynamic range. These are generated from the main DC Bus and filtered using multiple stages of inductor/capacitor filters, with Elna Silmic Capacitors forming the final stage.

Every section in the iDSD Pro has received massive attention to detail and combines classic design techniques for tube equipment with state-of-the-art technology to deliver extreme performance.

I have to say that this is a fantastic product. One of the only shortcomings is the remote control

This is a wonderful product. One of the only shortcomings is the Remote Controller. It works intermittently and only controls the volume. Is there a way or option to upgrade the remote to one that controlls the inputs and filters?Can I add a universal remote controller like the Harmony universal remote? If so, what are the remote code settings to add into the universal remote? Thank you.
