A long wait a superb work that Joseph have done on my HP2 were “i” means improved, a new double cable and some other things on the new drivers (I don’t know what…).
My old HP2 is now a NEW one and (I think) a very rare unit because the work of the friend Joseph with his 86 years old…
The can arrived some days ago to my door after 3 mounts of wait, but this is another HP2, incredibly better: new drivers, new cable for another quality of sound. This is MY phones, the only one!
I’m now using them with the EAR HP4 (Fivre 6sl7), but very soon I’ll have coming other two amps, just for the HP2i
1)The TTVJ Millet 307a
2)A hybrid one by an Italian builder with E80CC Telefunken and RGN1054 mesh Telefunken
I’m looking for the best amp for the best cans ever…
Thanks to Martin for helping me to contact Joseph Grado.
