As someone who is admittedly lackluster with experience with other High End IEMs on the market I feel I must preface this review by disclosing that the IEMs I am well familiar with are namely Campfire Solaris 2020, Atlas and IE800.

Therefore apart from a direct Solaris 2020 comparison this review will diverge from the standardised structure as not only do I not feel adequately competent to write it as such (with justice) but other reviewers on here have done more than a splendid job of them already.

I bought myself Solaris 2020 this summer and quickly jumped on the honeymoon phase with it.
Admiring not only the tonal balance where I found I also enjoyed them more then the aggressively bass-biased Atlas, but more so in its technical prowess.
Namely its renowned imaging qualities , separation and clarity.
A threat to this strong-bonded romance came one morning when an opportunity came to be a part of the Thummim review tour.
I was hesitant to accept taking part, fearing it might not only leave me uninterested in an IEM I so lovingly own but also install in me this rampant idea to go ahead and just put my car up on sale... ...
If this confuses any readers, then it might help to know this IEM costs a rather hefty 4500 USD. (...and the car is 2005 Opel - PM if interested) >JK.

And so just like a standard protagonist of an ancient greek mythological drama handles a lascivious adultery proposal, I, with a little degree of back-thought worry but more lavish enthusiasm, accepted the opportunity!

Now 10 days later into listening to Thummim, for most of the 10 days that the IEM has been loaned to me, urges me to share with you that after a swift and abrupt divorce my Solaris 2020 is on our beloved head fi trading forums. (Also plz pm if interested).


Hopeful chucklesome narrative aside Thummim simply outperforms Solaris in every segment and leaves me with what I thought previously possible by an IEM much surpassed.

On the technical front the IEM never skips a step. Its firm and clear instrument placement and separation is staggering. It places instruments spherically around your head but with a tone that is dense and yet not lacking in detail or air.
The timbre is life and analogue like. Presenting vocals with engaging thickness and clarity, low end that is gutural yet articularly controlled and highs that, the embedded 4 electrostatic drivers form, strike with such amazing fast transience.


In a more direct comparison with the Solaris 2020, the immediately obvious attribute to me was MMRs flagships thicker notes.

Most obvious difference in density is in the low end where Thummim also extends further and punches harder. Although control and speed are a lot closer between the two the CA flagship loses there slightly still.

Solaris' midrange has been my favorite part of that IEM as I feel CA had made it so that most of the listeners focus on said midrange, hence making it a very engaging and non fatiguing monitor in use.
Thumim also possesses a more thicker midrange, that is also more detailed and natural sounding, though I find Solaris able to hold its own the best in this regard. Vocals have a tendency to be placed closer to your face as opposed to further in front on the Thummim making it occasionally a more suited affair for me.

The Treble has a less energetic and more relaxed sound on the Singaporean flagship.
I Initially missed the Solaris exciting sparkle , but soon came to normalize to its tuning and was simply swept away by the detail retrieval and layering Thummim has on offer.
Add on top of that the surreal fast ride cymbal hits that appear like magickally spawned in the air this IEM continually kept me enchantingly amazed.

To put this comparison in short the Thummim is like slightly warmer Solaris 2020 on steroids.. And growth hormone. And insulin.. With some myostatine inhibition on top...And If bodybuilding paraphernalia eludes you, it's about three times as good by my emotionally hijacked estimation.



Thankful to @mvvRAZ for this amazing experience and for organizing the review tour. My girlfriend hates you.
