Pristine has slightly more mid-bass quantity with a similar rumble ability. The SE5 has tighter hits , while the Pristine’s sub-bass notes are more ‘’grand’’. Due to the mid-bass presentation style, Pristine provides slightly warmer signature, but both are very smooth.

Overall midrange picture is a little bigger on the Pristine and the transparency level is close. Both are natural and have slightly warm signature, while the Pristine is less effortless. The SE5 articulates midrange details a bit more but they both produce lower harmonics very well. In very fast metal tracks, both have congestion in instrument placement, but the SE5 provides a little more resolved presentation due to average note size. Both are very good in the upper midrange area and don’t tend to sibilance.

Pristine has slightly more prominent highs with a better tonality. The SE5’s treble sounds a bit edgy in comparison, but the speed performance is very close and they can both handle fast metal tracks.

Also, Pristine’s midrange seems to be closer to listener due to ‘’grand’’ notes, while the SE5 has more space around instruments. In very fast metal tracks the SE5 takes the separation advantage. In addition,the SE5 is more coherent and has better imaging.

In comparison, HUM provides better lower harmonics and sub-section body, but the resolution level is close. In the upper midrange, the Pristine is smoother, while Lear is less forgiving and tends to sibilance more.

The treble notes of Lear sounds mechanic in comparison. However the extension is better on Lear, but the Pristine has more natural tone with faster notes. Spatially, Lear betters the Pristine with deeper and wider stage structure; Lear locates instruments laid-back compared to the Pristine’s aggressive presentation style. In addition, Lear provides more neutral air between instruments; the Pristine seems to have more congested instrument placement, but it is more coherent and its presentation is easier to follow with a blacker and more stable background.

On the other hand, the Pristine has slightly more prominent mid-bass presentation with a more open tone. ACS Encore betters HUM in terms of sub-bass control, texture, and resolution.

On the other hand, the Encore betters the Pristine in terms of control and staying stable in fast metal tracks. In addition, the Encore has more space around vocals with more cleanliness.

Both are resolving, very natural, and fast in treble region. HUM Pristine’s treble notes are slightly weightier and have a more open tone by a small margin. In addition, both have roll-off problem in upper treble region.

The Pristine has a slightly wider stage and provides less warm air around instruments due to the dark presentation style of the Encore. On the other hand, the Encore has a deeper stage with a more distant and blacker background as well as a better separation. Both have a good imaging, but the Encore takes the lead in terms of being easier to follow and coherency. In addition, the Encore is less fatiguing due to the Pristine’s stage position.

Final Words:

HUM Pristine has an impressive performance in terms of tonality. When we look at its workmanship, two-way design and the sound provided, we can say that the engineering behind it deserves appreciation. However, its separation in fast tracks and stage depth might be better. Some may prefer its aggressive presentation style, but it is not a kind of bright or analytic style of aggressiveness. It is just a stage position. From what I read, HUM Pristine universal version seems to have a different sound than the custom version. Some say that universal version has a slightly bright signature. Customers need to consider that difference and a possible fit effect when they are deciding.
