This is a ShootOut review of some of iFi's most recent line-up – namely the two black labels and the two new "x" products. Before I start however, I thought worth setting out a few ground rules and my method, followed by a dive into scoring. Slightly differently to normal, I have given my method first before my conclusions (so that the conclusions have some context). I then go into a deeper dive for each category I have scored, giving my reasons and detail.

Method
For the purposes of this shootout, I have scored the iFi Micro iDSD Black Label ("Micro BL") , Nano iDSD Black Label ("Nano BL"), xDSD ("xDSD") and xCAN ("xCAN"). You will see in the table set out in the Scores section below, that I have ranked each of these products in the categories listed, giving each of them a total score. The product which is the best in each given category is ranked "1" and the worst ranked "4". Accordingly, the lowest overall score is the winner. I think worth noting that I am not saying that any of these products is objectively good or bad – I cover that detail in the full reviews (see below). What I am saying is that, ranked amongst the four iFi products I am looking at for the purposes of the ShootOut, the product which receives a score of 1 is the best of the four in that category.
To try to keep things consistent, I have reviewed the sound quality ("SQ") of these products by:
(i) plugging in headphones, playing a constant 10khz tone, then adjusting volume to the same level using the microphone on my Samsung Note8 and the SPL Meter app (to get an approximate volume match);
(ii) reviewing using the Sennheiser HD600 headphones and the CTM DaVinci X IEMs which I had on loan from CTM for a review (in both cases, volume matched as above); and
(iii) using the same tracks from Tidal (all 44.1/16, not MQA) through USB input on each of the Nano BL, Micro BL and xDSD, and Bluetooth input on the xCAN (given it is an amplifier, I found it quite source dependent for SQ – as one would hope!) . Just for clarity, this means the xCAN is not being fully and fairly compared in these sections, but it is a different product (an amp with a Bluetooth input rather than a "full" amp/DAC).
I have decided not to mark for boxing and accessories as all products would receive the same mark here – top class product packing and all necessary accessories included in box.
In the full ShootOut section below, I then go into some detail justifying each of my scores. I have also written full reviews for each of these products:
Micro BL – to follow
Nano BL - https://www.head-fi.org/showcase/ifi-audio-nano-idsd-black-label.22770/reviews#review-19514
xDSD - https://www.head-fi.org/showcase/ifi-audio-xdsd.23046/reviews#review-20586
xCAN – to follow
Conclusion
My overall conclusion is that, if you were planning to spend your money on one of the four products reviewed, the best buy is the Micro BL. Controversially though, it isn’t the one I would choose to buy! The device that I keep going back to, and that I want in my stable is the xDSD. I could have rigged my scoring system to deliver the result I wanted, but I have tried to be objective, and I stand by the conclusion that, objectively, the Micro BL delivers the most out of all of these iFi products… it is also the most expensive. However, it is most definitely a desk based unit, and the perfect mix of SQ, features and overall desirability for me is the xDSD. As ever, YMMV and you would be perfectly entitled to tell me that this whole ShootOut was a massive waste of time because despite the fact it was designed by me, I disagree with the result.
