I would like to shill the Grado Hemps as I love them and think they check off…
- Timber
- Warmer
- More open
- Possibly slower transients (attack/decay)
I say this only because of my experience with the Hemps as I have not heard the elex. If you want to read more if what I and others think of the Hemps, check out the full thread.
Also I hear the hagerman tuba is good for Grados if you still want to get a tuba amp to play with.
