Good ol fasion transformer like the EF2 comes with is good enough, that is, if the problem with the PSU quality control was fixed. I'm still using my home-made 16v wallwart with a good transformer as my original PSU died in 2 days..
Well ,
No One Is Saying Make a SMPS Mode Supply ,I Am Saying It Should Look Like a Adapter of a Laptop ,Thats More sturdy .Mine Body is Already Cracked .

Identical sound signature. EF2A output is a little higher than EF2.
