Still trying to sell mine thank you for the consideration!
For people that have been waiting for Penon to carry them. Here it is. https://penonaudio.com/lz-a5-filters.html

nice 1. I am revisiting these. couldnt keep away...lol.Waiting for the new filters to arrive - and then plan to remeasure them. Will post results when they arrive
So apparently filters are as follows:
Blue : 3KHz ~ 10KHz +2db
Black: 3KHz ~ 10KHz +1db
Gray : 3KHz ~ 10KHz -1db
Red : 3KHz ~ 10KHz -2db
Also, these start out from 8HZ (A4's were marketed as 10Hz with red filter) so there is a high possibility for more sub-bass rumble. Yay!
Can you please explain these 2 graphs? Both graphs show great differences between 1kHz and 3Khz, and the first one even under 200Hz, while the filters should affect 3-10kHz.
Vs new filters
Seems new filters went completely away from previous overly bight upper mid enhanced filters all together. The new filters is much more sensible so far as sound balancing goes. In a bit of a surprise I was not supposed to get my filters in till tomorrow. They are at my house as I type. Will be very interesting to hear how they do compared to older filters. It looks like they fine tuned the Grey and Red filters and the new grey and reds should have even lesser degree of empahsis. Might be a bit subdued compared to the originals.
They might even be a bit borning. lol

OK - as promised, new filters arrived. Series of graphs to follow.
Usual disclaimer with my measurements:
The graphs below are generated using the Vibro Veritas coupler and ARTA software. Ken Ball (ALO/Campfire) graciously provided me with measurement data which I have used to recalibrate my Veritas so that it mimics an IEC 711 measurement standard (Ken uses two separate BK ear simulators, we measured the same set of IEMs, and I built my calibration curve from shared data). I do not claim that this data is 100% accurate, but it is very consistent, and is as close as I can get to the IEC 711 standard on my budget. I suspect it is slightly down at around 9-10 kHz, but seems reasonably accurate through the rest of the spectrum.
I do not claim that the measurements are in any way more accurate than anyone else's, but they have been proven to be consistent and I think they should be enough to give a reasonable idea of response - especially if you've followed any of my other reviews. When measuring I usually always use crystal foam tips (so medium bore opening) - and the reason I use them is for very consistent seal and placement depth in the coupler. I use the same amp (E11K) for all my measurements - and output is under 1 ohm.
Any graphs are provided merely as a point of discussion. Both sets of measurements were taken on the same rig with same tips. Click graphs for larger images:
Blue Filters
As you can see - pretty much identical. Virtually no change with the blues
Black Filters
Again very similar - but this time the black is slightly down in the upper mids.
Grey Filters
Quite a marked difference. The old grey were almost identical to the red. These ones have a bump in the mid-range and also the lower treble.
Red Filters
Again - practically identical.
So lets look at the old filters all together:
Yep - too much alike, and more like two pairs than 4 separate tunings.
And now the new filters:
Definitely some more variety this time
My take - once again, I really only like the red and grey. Red is quite warm, but still has nice overall balance (esp if you EQ a little bass out). The grey this time is quite good also. Definitely V shaped, but the enhanced upper mids and lower treble help counter the bass, and aren't too peaky.
Would have liked something between the red and grey - but defintiely this is an improvement on the originals.
