I've just shipped out the Fir Audio tour kit to the next Canadian user & am thankful for
@Rockwell75 for the opportunity in getting some in-house time with the VE EXT, Phonix and 3 shiny Firs.
Of the 5 iem's, my favorite is the EXT, though I hate to say it, none of these are really compelling offerings for their pricetag if I am going to be critical.
If anything, I am extremely impressed by how the likes of IER-Z1R, KSE1500 & arguable even the IE900 vastly outperform the price they command.
The IER-Z1R, on average/ good sources like DX300 + AMP12, Matrix Mini i-Pro3 or lower ones like L&P W2 consistently performed on a higher echelon except for raw detail retrieval vs Phonix.
This made me want to demo on my main source with a desktop amp that can do iem's - Bricasti M1se + BHA-1 - to see if I could get the Fir or Vision Ears to scale to their potential. Well... against my hopes, it really just scaled the Z1R and IE900 to high levels & the KSE1200 with custom energizer scaled stratospherically, near Susvara/ X9000 levels.
The landscape we live in is a bit discouraging in my opinion. I've owned most top flight iem's up until the 2022 and finally settled on a roster of 4 iem's that do all I need and more.
I bought MEST Indigo & Odin, and genuinely loved them. But then again, IE900 was knocking at their door but for a fraction of the price but with better transients, dynamics, coherence and a more functional day-to-day form factor - reality came down crashing over me. Indigo is the champ for me when it comes to holography and blown out/ large image with a great tuning, but it's victim of a hashy and grainy upper treble. So I sold it. Odin's the best Empire Ears iem, and by a landslide, but then again, as a product it feels kind of cheap, the stormbreaker cable is... how expensive and why? I loved its upper midrange forwardness, it really helps with microdetail, but you live and die by the tuning. Poor recordings are not welcomed. As most Empire Ears iem's, there is suppression of the upper treble, and truncated decays, air is no really there and it favors a more focused sound. It makes for an engaging and dynamic listen, with good detail and resolution, though still not Z1R level.
This ended up sounding like a pissy rant. but really it's just a constructive criticism of the state of porta-fi in my opinion. Every 6 months something new and shiny is released but it's never really a revolutionary product. There are definitely creative ideas that have come to be in the last 3 years especially - UM quadbrids, the increased usage of electrets as super tweeters, Fir's proprietary bass system but in the end, I think sometimes less is more.
- You will never beat a single driver and no crossover in-signal when it comes to time coherency. Perhaps the limitations are still extraction of raw detail from a single DD vs multi-ba + DD's, but then again IE900 proves that properly developed in-house drivers are better than off-the-shelf components and stands among the best. The Shure KSE has no following anymore probably due to its cumbersome use and cheap-ish shell/ non-detachable cable, though it remains to this day the single most detailed in-ear ever made, which is an objective. This was released in 2016 - basically forever ago in audio metrics.
I want to see someone make another full-range conventional e-stat transducer; there hasn't even been one hit the market since Shure did it.
To this day I still prefer my sub 2K iem's over my Mason Red Halo FE which is telling. Love this iem, but really not sure where my money went
