RA-1/clone + er4-s

[Natsuiro]

Has anyone tried the RA-1 or a clone with the er4/s?
I am currently using a MisterX built pimeta with AD8620 op amp, and was thinking about something with a different flavour. Does the RA-1 have more bass and sound quite warm? The RA-1 is made to drive lower impedence headphones, so would the er4/s with 100 Ohm impedence or so (forgot) be ok? thx alot.

ying and yang man.The Grado op-amp puts out 70ma and your pimeta already has a high current buffer so impedance/current drive is not an issue but more a voicing thing.

if the opamp is socketed try opamp "rolling" to change the tonal character of your present amp

The RA-1 works fine with etys, but it is nothing special (though I am on record here for thinking that the RA-1 is nothing special in general.) The Grado is, o my ears, dry and dull sounding. For a warm bassy amp with the etys for not too much cash (about as much as a used Grado), try a pete millett hybrid.
