So i said I would report back, here goes.
Summary- no difference for me between L90 and P30/70.
Fitted L90 by Boots late December, was going to be £2900 with the offer.
Got home to find I was on APD so changed to NAL2 in order to compare properly.
Changed molds to my old ones as the new had vents despite it being a reorder!
Did a FBRE test, put my 03 licences on and other stuff like tv connector etc.
Overall sound is the same as my P30, so is streaming.
Autosense in loud noise was disappointing, just reducing all volume including speech in close proximity.
No real difference using the app presets or sliders.
Managed to get back to Boots in three weeks for adjustments.
She suggested soft noise reduction which I thought was a bit odd but went along with it.
All volumes affected so I reverted to base.
It was now early February and when I tried to book it was going to be May! Well outside the trial period. So I returned them and booked with Specsavers for late March. They were £700 cheaper than Boots for L50 that I was going to be content with.
As my P30’s are out of warranty I was keeping a watch on Ebay for some new aids.
So late March I get ready for Specsavers wondering how to play it, expecting the quick sell.
What a revelation. A very pleasant and bright young lady who was a hearing aid user! Next bit of conversation was that she was a cello player! Am I dreaming or what?
Turned out her grandfather had dementia and loved music so she learned to play.
So now I am thinking I’ve won the audiologist lottery and this could be a very constructive when she pulls up the audiogram from two years ago. I used it to try to get the NHS clinic to retest me.
Have you never been told you are a candidate for a cochlear implant?
Bang! Very obvious in hindsight but so unexpected.
I don’t want to sell aids to people who won’t get proper benefit from them.
So she did the hearing test and it was as expected and said she could refer me for CI evaluation, so I said yes. If I survive I may get to the bottom of my speech recognition issues.
In the meantime @Zebras had a nearly new P70 for sale which I bought and I bought a new one from Ebay for £300 so I have a reliable setup.
I’ve precied this post but my judgement of this lady was that she was a genuine caring person.
As for the comparison of L and P it proves the point that we are all different.
I am glad you are sorted @michael1… Especially so, when you got your aids at a knockdown price, it’s always nice to get a bargain, well done you Sir 
We are indeed all different, we are all individuals, in truth our personal sound preferences are unique, to us alone… Some of us, (especially me) might be termed as “Cheapskates” but, I wear that badge with pride, I will buy new, if I am forced too, but if I can circumvent that option, I will gladly choose second hand, as this means, I can afford other ALD’s… I would not be able to afford or justify some of the equipment that I have, if it weren’t for the likes of eBay… Good luck with your CI assessment, cheers Kev 
On another note, regarding thick wall tubes, it seems like puretone.net supplies other online seller:
Only downside buying from them is the exorbitant shipping cost if under £50 
Fortunately @Baltazard I get mines as part of the service from my A.uD, free gratis I do not buy from companies, that charge OTT shipping, I dismiss them immediately, when I am on the lookout for any product… That price for for shipping is exorbitant, a Jiffy bag, and a first class stamp, will be no more than £2… Tubing must cost about 2p each to make 
Some folks get their money easy… Cheers Kev
I re-added Autosense the other day and found it a little better than I remember. I’ve decided the thing I dislike most, about it, is beamforming. Last night I went into each of the elements that make up Autosense4 and reduced the beamforming slider to zero. Sadly, however, “Speech In Very Loud Noise” doesn’t have that option, so I fear, a Very Loud environmend will be useless for me.
I believe, my expectations of Phonak aids mean I don’t need the expensive versions. Certainly no need for the P90 version.
Peter
I got mine from HAB hearing in Keighley, not expensive i think they were £15 for 5.
I am noticing a slightly strange phenomenon on the Naida Lumity 90 UP BTE, well not exactly the aid’s themselves, namely the Ear Hook, I am thinking, it’s just as well, I have a box of them, otherwise I would be running back and forth to the audiologist every 6 weeks or so… The white damper swells up, and jams into the widest part of the Ear Hook (see image) completely sealing in, all the sound, rendering the aid useless, until the Ear Hook is replaced… Now, either my ears are producing much more moisture, or Phonak have changed the material they use for their dampers? My aids go into a drier every night… Anyone else encountering this problem? Cheers Kev
Yeah that’s strange, if they have changed it they didn’t test it!
Maybe the temperature of the dryer and new material is not compatible?
Hi @PeterH
you can exclude “Speech In Loud Noise” from Autosense and create a dedicated manual programm for “Speech In Loud Noise”.
Remove the check mark at “Autosense OS” programm options (see point 4)
Then add a additional Programm for “Speech In Loud Noise” see 5)
This is the view you get after you click on the + symbol to Add a programm:
You need to select create a linked program for “Speech In Loud Noise” so you can then manualy access this via push button or via app
I have had that drier, for 3 or 4 years now, it still heats up, and puts out UV light… In my experience, Ear Hooks, do not swell up and block, well sometimes they do, but it’s a rare phenomenon, it’s only happened once before, with my Paradise aids, but never with any other aids, 6 weeks or so ago, both Lumity aids damper blocked up simultaneously, with no sound whatsoever emitting, I thought at the time, both aids had failed, but no, it was the damper that blocked… I think, it has to be material failure? Or lack of testing as you rightly suggested…Cheers Kev :
It’s Marked as 10 in the bag from Puretone… And if you think about it, why would anyone sell an uneven number like 5, the vast majority of us have 2 aids… The ones marked USA, come in packs of 20… I get my A.uD at Boots to order them for me. Cheers Kev
Just out of interest, what is the importance of this damper pad. Since 2009 when I was first prescribed with (UK) NHS aids, I was mostly prescribed with earhooks and full mo(u)lds. In 2015 I was told thin tubes and closed (2 holes) domes would be ok for my loss… they were lazy and wrong on this, but they didn’t have damper pads.
Anyway, I pushed these dampers out of some early earhooks, and all seemed ok after that, and the aids worked until the day I had enough backup sets to just throw them out.
On my Bolero Marvel M70s, I’ve replaced the earhooks and thick tubes with thin tubes and custom slimtips. There’s no damper between the ear and the aid in this scenario, so it makes me wonder why it’s need in the earhook/thick tube?
Peter
Not 100% sure either @Baltazard or @PeterH I always assumed the damper was for preventing too much moisture getting back into the aid, perhaps I assumed wrongly? Cheers Kev
The five i got from hab were stay dry ones and seem to be a different rubbery material.
Never had problems with dampers and no drier.
Could it be the drier UV that causes the plastic to swell or hair drier soften the plastic (too high temperature).
The damper/filter is in there to reduced an acoustic resonance of the hook/tubing.
They are a bit of a historical throwback to peakier receivers in aids with fewer channels, where you couldn’t easily control the MPO bang on the peak resonance without affecting gain elsewhere.
They’re not designed as a vapour barrier as the mesh is open.
Thank you @Um_bongo for that clarification, yeah on recollection, I have read the damper was to do with acoustics, so can we dispense with it, as it appears to be a throwback from yesteryear, or is it still important? Cheers Kev
Shouldn’t just be binned if the SW already includes it. However the aid should be capable of replicating its function.
Thank you Stephen… As always, we are much obliged for your knowledgeable response Cheers Kev
