i used the Lawton mod for my Fostex Tr x00 Mahagony and the Denon D2000.I do it my self.It was simply do it.
On the Tr x 00 it was so much better as before after the Mod.
More controled Bass and mid,the Highs not so sharp.
But the Mahagony cups are not god,the sharpness was better after but not suffisant enough.
It was a little bit better with the Ahg Pads and Dekoni rings.
In future i plan other cups maybe from Emu or lawton.
I am not sure yet.
On the Denon 2000 it was simply to install the Mod.
After it was better too,more controled bass and mids,and the highs more control and not so harsh.
I complete the Mod with the Roseeood cups from Emu.
Too install the cups was not so easy to made, because i must cut the nodes for a better closing the cups.So i must be put out the driver from the frame for a good cut.
After change the Cups it was better as the Tr x00 Mahagony and the plastic cups from the Denon.
More bass and sub bass,with good control,the mids goes deeper,
And the Highs very beautiful not so high and not so sharp.
A better desortation, more natural and the Voices from the singer more volume,gives more Room as before.
I find it better as the D7200 out of the box because the Bass from the Mod is more natural and not blow up in comparision.
The Lawton mod is Good thing for the first, good investion.
For Later with cups i depend how much money you will spend.
I am sure the Lawton cups goes a bit better as the Emu in Sound.The finish from the Cups the Lawton are awsome,very beautiful.
The Emu have a good character with her Cups in sound and a good finsih for the price.
A Good thing is to change the cabel,i have buy the Fostex connectors on alliexpress and complet it with the Viablue EPC2 cabel.
The Via blue cabel is a silver cabel with a good Isolation.
Here the List:
It possible to buy for European buddys in England the Dekoni Rings.
The Lawton mod only by Lawton in Usa and the Cups.
The Emu cups only by Emu on her Webside.
Here same from the D2000 mod.
