#Pure synergy serial number#

The 8 core uses the 5.xx version firmware while the 16 core uses the 7.xx versions and I need to remind everyone that the firmware versions are not interchangeable.

#Pure synergy serial number#

You could tell which version of DAC you have by the firmware version or the serial number but not visually anymore. Now both HFM and the newly boxed 6xx variants come with the 16 core XMOS DAC section. When the 6xx variant was reviewed I actually got the second iteration of the DROP variant which still came with the 8 core XMOS DAC but the front panel was changed to look identical to the ZEN Signature version 2 DAC. Other than that the amplifier section specifications remain similar to the original ZEN CAN but with a different color scheme and a couple of tiny build tweaks very similar to the 6xx variant. The other change that has taken place is with the bundled power supplies but not much else has changed or so it seems.

The differences between the two sets, the 6xx and the HFM variants are in the tuning and effects of the HFM feature on the amplifier section which replaces the 6xx feature. However, we have a review sample nonetheless and will probably go further in-depth with this HFM set insofar as the effects this Set has on Hifiman headphones. The HFM set was introduced right under our noses and in iFi AudioвЂ™s typically surprising manner.

Since I have a few Hifiman cans iFi Audio decided to send one over for review. What I was looking at was basically the same dish with a different sauce.ДЄs I was scanning the iFi Audio webpage I ran into another similar ZEN stack Signature Series but it was an HFM set tuned for Hifiman cans so I immediately started to look around for one. At one point I thought I was seeing double, then thought perhaps my eyes were failing me. A funny thing happened to me as I was doing research to write up the original iFi Audio ZEN Signature Set review.
