Brilliant, I hadn't thought of this! hypothetically, if you had a device that needs 7Amps, can it pull the 7A from two 4A PSU's ? https://musicmaker.ie/voodoo-lab-vl-ppav-output-splitter-barrel-y-cable-4-in?

You can get an open box Sundara direct from HifiMan for $209 or $239 depending on where you live. I've bought the Ananda + Sundara open boxes and they both appeared to be brand new. https://store.hifiman.com/clearance-sales

I thought maybe the voltage protector on the Diablo was faulty and if you dropped HYPSOS slightly to 4.7Volts it might work.

I believe those 50Watt phone chargers have stepped voltage, so on mine at 5 Volts it can only put out 3 Amps. The 50W can only be had when it steps up to 20V. Thorsten said, even the original spec for the Zen-Can was supposed to be 5V with 5 Amps but instead iFi shipped it with 2.5A thus...

Thor, I'm not sure what the maximum Amps this will deliver to the Zen-Can amp ? https://Aliexpress.com/item/1005004825653850.html

I had both the regular Zen-Dac and the Signature-Zen-Dac for a month. the Signature definitely sounds better. It's more detailed and clearer. I still use the Signature version today. For me the power supply makes no difference, the Signature is just a better sounding Dac.

@iFi audio you should send this guy the Signature Zen's to review. He enjoys Zen-Can over many other Amps.

@iFi audio you got a good review here on the Zen-Can Amp.

Yes, I've switched back and forth about 50 times over the last couple of years.

@iFi audio @Sebastien Chiu Does the newest 7.4b firmware still have the older but great sounding "Symmetrical FIR Filter" ?? "The filter in 7.2B is a symmetrical FIR filter, using three cascaded FIR interpolation filters which are equivalent to appx. 75,000 tap filter at 8 X Oversampling...

@iFi audio can you tell us is the the X-Bass on the new Air-Dac the same excellent "X-Bass" that's on the original Zen-Can or is it the heavier "True-Bass" that's on the original Zen-Dac that's too strong a boost for most music ?

The regular Zen-Dac V1 and V2 sound the exact same, I owned both. I now use the the Signature-Zen-Dac which does sound better, as it has more detail and music sounds less compressed compared to the regular Zen-Dac.

You could get an open box Ananda for $580 with Coupon Code (NewYear19) ►https://store.HifiMan.com/index.php/open-box.html

I had this problem a couple of times - for me it goes away if I only use USB power. It may have been the particular power supply unit I use.

@iFi audio Will there be a Signature-Zen-Can amp that just has the standard X-Bass ??
