Austin Taylor (http://www.austin-taylor.co.uk/index.php?page=adsl-splitters)
Had a report from a collegue that the Austin Taylor faceplate improved/reduced his attenuation by 5dB.
Have ordered 2 for testing just curious if anyone had one of these?
SO far i have a clarity a genuine bt nte 2005 and an adsl nation.
On my line the adsl nation is the worst with the clarity and bt about the same, I have stripped apart all of them and the adsl nation seems to use active components as oppossed to passive of the other 2, looking at the pictures of the internals of the Austin Taylor the component quality looks "better".
When i get it i will do a write up and photo of all the internals.
Haven't even heard of them, tbh, Dean, so I'll be interested to hear your opinion.
Do changing these things really help a *lot*? I have some generic BT wall plug thing which is kind of wonky as was installed with the house and some free ADSL filter I got with some computer order years ago...

Be interesting if you did do a write up :)
I mentioned over on another thread that I couldn't understand quite why people rated the ADSL Nation product so highly. Of those my friends and I have used - BT, Clarity and ADSL nation - the only ones that have failed have been the ADSL Nation ones. OK they've been replaced without quibble, but I became convinced they were more prone to failure because, as you say, they are an active rather than passive filter with more components to fail.
I think the BT and Clarity ones are made by Pressac.
I think the BT and Clarity ones are made by Pressac---Correct
A Descent filter makes little or no differance on a line with sub 30dB attenuation.
However on a long line the differance is much more noticable. (or a line prone to interferance)
The reason i am doing so many tests on different suppliers (and have been given a fairly substantiale budget) is my company are currently in the middle of an adsl voip roll out of 120 stores.
Some are fine but some are on end of lines, one i investiageted was on 71dB attenuation and download speed was a miserly 800Kb, the adsl bandwidth graphs looked really strange.
A visit with a BT engineer showed they had not used a single pair but a wire on two different pairs (split pair scenario) bought attenuation down to 58dB but more importantly the graphs started to look more normal. fitted an nte-2005 and it reduced the attenuation down to 49dB the download sync now at 2049Mb.
I have to do a report for the company anyway's so duplicating it here is not a problem.
I guess the last stage (ie. BT network to your house) that goes through the filter generates contact 1/f noise, so a low S/N from a long line would get totally drowned... I have to admit my understand of all this is pretty weak.
The BT i-plate near doubled my internet speed.
Pulling the ring wire is cheaper. ;)
Wow faceplate suppliers are fast i now have 5 of the 6 ordered on my workbench.
trouble is after taking them apart 3 of the 5 are identical apart from the secondary pcb which supplies adsl wires as well as standard 235 wires.
Hmm me thinking not many real manufactureres just a load of hype and re-badging/silk screening.
just to keep you all on the edge of your seats Austin Taylor and ADSL nation are the 2 odd ones so far.
when i do the review/testing i am going to use a friends troublesome adsl, he has 3 sky boxes and a real nightmare of internal wiring, i keep promising to sort it out for him and have promised i will fix it this weekend. ideal testing ground, coz i don't care if i down his profile :) currently 2Mb and he lives under a mile from exchange!!! (have already proved test socket and a sync of 6Mb) so excellent testing ground for filtering properly.
Interesting. Looking forward to the results.
