Sorry for the long post but this should get you sorted.
The difference in sync speed between the master and test socket is most likely down to the time of day you plugged it in. You will get higher syncs in the day, at less busy times. About 10AM is the best time re-sync but it will vary from area to area, that's a good bet though.
Your line attenuation is the same in the master and test socket so you should get the same speeds in either after it's plugged in for a while and settled down.
Your noise margin has gone up in the test socket most likely because of re-syncing so often. That's normal and it'll drop in time if you leave it connected.
That speed is exactly what you should be getting for the stats in your test socket. And you'll probably get the same when plugged into the master.
What I would do now is a quiet line test, as suggested above, if that's clear, re-attach the faceplate/filter/internet/phone, then leave it connected 24/7 for at least 3 days or untill your downstream noise margin drops to about 6. Then do a re-sync, idealy about 10AM, definatly not after 4-5PM or when it's dark.
If all is well you should sync a bit higher and get an extra half a meg to 3.5Mb from the 3Mb your getting now. There is a handy table here that shows you the sync rates vs ip profile steps, you only need a bit higher sync to move you up a step for the 3.5Mb.
My old line had 52db attenuation and I was able to maintain a 3.5Mb speed with some strategic re-syncs, yours probably can too.
Once you've got that sorted you could get a filtered faceplate, bt do one called the iPlate and adsl nation do one aswell, they should both perform the same. Then you can install that and re-attatch your extentions. There would be no need for filters at every socket then either.

) and needless to say i never have any disconnection troubles, downtime, or even slow speed due to congestion, its always 95% or more of the rated speed, which is what really ticks me off with todays adsl suppliers, they say up to 2000000000Mb/s and you get a fraction of that.
