As someone living on the West Coast, USA, what dealer should I pre-order from to guarantee I get one of the special first production units? Will all authorized dealers in the US be getting the special first batch?

I'm guessing it's the switch between a fixed 2Vrms line-out and a variable line-out which have both been said to be Class A (only the headphone amp eploys op-amps)

*edit* One feature I do still hope to be added is that the variable line-out goes beyond the 2Vrms. This would be helpful for vinyl-turned-digital signals which are normally of lower volume. It would surely help as my powered monitors have their volume control all the way at the back.

Coming all the way from the Philippines, I doubt those special first production units will even reach us but if there are ways, may I ask who I should be contacting/pre-ordering?

is it really a different between first batch and the rest.

does the first really better sound?

Speculation suggests the use of NOS parts so once those run out, iFi would be using the second best or at the least, their second choice

Hi,

 

iDSD micro specification redux...

 

Folks, we totally forgot to mention one more kool feature (way too much stuff happening :wink_face:).

 

The iDSD micro will have a switch allowing to be selected as either direct DAC line out (2V, Fixed Level) or as variable Preamp out with X-Bass available and up to around 4V RMS output. So if you want to use your own preamp, have it your way. If you want to just drive active speakers and not fork out for a preamp, have it your way.

 

The switch is below the RCA Sockets, so not in the pictures we posted of the mechanical design, hence it was forgotten.

 

 

It seems I've found the answer to my own post!! Variable preamp out reaches up to 4Vrms!! Yay

Hi,

 

Sorry we do not use Femto clocks in any AMR/iFi products. Femto clocks are for SONET, not audio, so not as ideal as one thinks.

 

We wrote about this a few pages back on the Global Master Timing module in the micro iDSD (from the DP-777). It has better femto seconds performance than the Femto clock (which in turn is better than normal clocks).

 

Also, to clarify, the extras are on the outside, not the inside and there actually 3 items  :wink_face:.

Hi,

 

Drop Avatar Acoustics a line. They are the AMR/iFi distributor for North America:

 

+1 (678) 817 0573 / +1 (305) 608-6079

DCensullo@avataracoustics.com

 

or you can go your local retailer.

 

(but Avatar noting your pre-order is probably best).

 

Cheers

is the iPurifier one of them?!

Some of you with experience of the nano or micro iCAN will already be familiar with our XBass feature in the upcoming micro iDSD.

 

But for others, we hope you find this interesting.

 

 

Super Duper feature 2.0

 

XBass (not all headphones are created equal)

 

 

 

 

Background

“Listening to the radio I feel so out of place

There's a certain something missing that the treble can't erase

I know you can tell just by looking at my face

A word about my weakness I'm totally addicted to bass”

 

The Puretones – “Totally Addicted to Bass”

 

 

No one headphone produces a perfect bass response.

 

 

Explanation

Between different recordings and different headphones, bass is often found wanting.

 

To have Bass or not to have Bass, that is not the question here

Listening to great music is always a positive experience; from the most humble to the most extravagant system, all are capable of providing great enjoyment. However just as in the song by the Puretones, if the Bass is not right, then “There's a certain something missing that the treble can't erase”.

 

With headphones, bass performance varies widely. Some headphones have prodigious bass, some have perfect, even-handed bass, yet many others are bass shy or have severely missing bass. There is no direct link to cost in this, some rather inexpensive headphones can have killer bass, while rather more expensive headphones are found lacking. Of course, bass performance is only ONE factor in Headphone sound quality.

 

Here are some representative frequency responses of different headphones:

 

*

 

Leftmost is the Ideal curve, this is what a headphone SHOULD measure like. Real ones never do. The other three are examples of REAL headphones and show their varying degrees of bass response.

 

Going from second left, real world Example 1 has very good real bass. Such headphones are quite rare though.

 

Example 2 has some attenuation in the bass. This is often found even with rather expensive headphones. This curve is indicative of a certain US$ 1,500 Headphone which is all around excellent and of the best ever made, yet the bass is still a little lacking, not that one would call it bad, but always leaves one wishing for more.

 

Example 3 is typical of many smaller headphones. Bass is noticeably absent; not just a little at the very bottom, but a big chunk has gone AWOL. Such headphones do sound distinctly lacking in bass; thin, weedy and unsatisfying. They make some correction mandatory.

 

Another possibility that is not shown is that the headphone will have a very heavy, boosted bass, some DJ Headphones and some in-ear-monitors types are like this. Depending on music and taste this may be perceived as a good thing, or not. For such headphones it is very important that the headphone amplifier has a very good damping factor, so that the extra bass is well-controlled without becoming boomy. To show what actual, real headphones look like, below is a comparative shot of four different ones measured by HeadRoom.

 

 

 

At iFi we have been aware of this common bass problem with many headphones. Oddly, headphones with the best bass are rarely those with the cleanest midrange or the best imaging. Hence buying headphones is often a compromise.

 

i) One could buy a set of headphones that has almost everything and give up a bit of bass. With the player software, the equaliser function could be adjusted to compensate for the lack of bass. But this brings into play DSP and the music signal is no longer Bit-Perfect.

 

ii) And of course, with your iPod or Laptop, the limits become obvious: the limited power output simply cannot supply the extra power needed for the equalised bass and sound becomes distorted, so you have to turn the volume down, but you do regain some lost bass. It still often does not sound that natural either, as few of these equalisers are correctly tailored to compensate for the shortcomings of headphones…

 

Enter XBass...

 

 

How this benefits the listener

If your headphones leave your craving for deep, clear, solid bass unsatisfied, you need something eXtra. You need eXtra-Bass. XBass - adds back the "missing bass" and the customer is able to dial-in their desired level. As with other iFi features, this is performed in the analogue domain so the music signal remains original.

 

Further, as XBass is integrated in the micro iDSD Headphone Amplifier we have more than enough power to add the bass back without distortion - the extra bass is tight, crisp and precise.  

 

XBass is integrated into the micro iDSD (along with nano and micro iCANs). Just flick the switch to ON and away you go. If you find it doesn't suit a particular headphone or track, just switch it to OFF. 

 

Wanna make your 'phones the Ace of Bass? then checkout XBass...

Hi,

 

Nope. 

 

These 3 items are not audio-related.
