I was kinda hoping to not want/need another headamp ever again after getting the M9, but it will be nice to have both the M9 and the GS-X. One a nuts-out "wire with gain" monster, the other a more subtle presentation. That's the thinking, at least. Will see how it works out after I get the amp and have a few weeks listening with it.
Did you receive your GSX MKII ?
If you did, could you please share some impressions and do a comparison versus your Master 9.
I own a Master 9 as well and sometimes with LCD-4 I feel I need just a little bit more grunt, raw speed and impact to be perfect.
I hope GSX does exactly that.
Thanks in advance!
