Got a chance to sit down and Give 7Keys Senn Grado a listen, it's been a really busy couple of weeks for me. In between work, holidays, finals and a couple of deaths I've not had much free time.
Compared to my Walnut Senn Grado, 7Keys Western Red Cedar I noticed his had a little bit more lower mid body. guitars and other stringed instruments had more weight to them compared to my Walnut Senn Grado, in addition the Western Red Cedar SennGrado was a little smoother on the top end, not as articulate as the Walnut I have, and also not as edgy at times.
Both did a nice job with imaging and had a natural tone. I did prefer the cleaner tone of my Walnut Senn Grado, but joes Western Red Cedar was a little easy to listen to. Not as harsh or revealing of a poor source of file.
I also felt the Western Red Cedar Senn Grado was a CLEAR step above my Walnut Allesandro MS1i, where the MS1i W can be, both warm n loose and grainy, the Western Red Cedar Senn Grado had neither of those issues, so considering the price differances the Senn Grado regardless of wood is still a great bang for the buck!
