3d+:
3d+ is a fully analog crossfeed implementation, which adds a delayed and lower level of the L-channel audio into the right and vice versa, to simulate a speaker-like effect.
The graph below shows the crosstalk when 3d+ is enabled, and a scope view showing how one channel is slightly delayed (intentionally).
This isn’t personally my thing but it’s a nice feature to have and definitely works with some ‘hard-panned’ recordings.

Hello !
I congratulate you for the initiative you had creating this site where, in addition to “subjective” opinions and reviews, we also have access to objective measurements, in the style of Audio Science Review.
I am one of your followers on your youtube channel and now I will be one of the followers of your site.
I would have a suggestion, if you don’t mind: for those like me, less technical individuals, maybe some comments accompanying the measurements would be good, so that we can better understand what it’s about.
I wish you success in the future in everything you undertake !
(Please excuse my English, it’s not my native language)
Thanks!
I have a video coming which will be a bit of a ‘measurements for dummies’ type thing. And I’ll do a written version as well. Should hopefully be done soon.
For example, in the “1 khz 4v Unity gain 32 Ohm” graph, there is a discrepancy between the L and R channel: THD + N ratio = 0.001745% vs. 0.002740% and SINAD = 95.166 dB vs. 91,245 dB. Is this difference significant ? If the answer is “yes”, can we know where it might come from? And, most important, can this be detected subjectively, by listen to music through HP conducted by iFi Zen Can ?
Also, in the graph with “1khz 700mv (Headphone Level) 32 Ohm” (but also in the ones at other impedances), there are discrepancies between the RMS level of the L and R channel: 675.9 mVrms vs. 709.2 mVrms. Are these differences significant and subjectively detectable in practice ?
Another question: is the performance of the “Multitone” test good or mediocre with that “grass” in the graph going up to – 100 dB SPL?
Thanks a lot !
This isn’t entirely uncommon. In this case, the zen can has a little bit of channel imbalance anyway so that will be a factor. But also no amp is going to have both channels be absolutely 100% identical.
It is a difference that leans on the larger side but not enough to worry about.
In the multitone test, it’s ok, but the fact that it has rising distortion/noise into the upper frequencies (also visible on the THD+N/Frequency graph) is a bit concerning
I may have missed it but is this the balanced or single-ended output being tested?
Good question.. not clear to me either
Sorry should have mentioned that clearly, its balanced in balanced out. Will run and add SE reports later
Cheers!
Congrats on your channel and now website. I look forward to your content. It’s delivered in a way that holds my attention, which for being quite analytical, says a lot. Good luck going forward.
Considering that ifi Zen Can has an analog volume control, it would be helpful a L – R channel balance vs. Volume plot/chart.
Do you think the Zen Can is sufficient enough for Arya v2’s? – maxing out at 0.8w – Thanks!
