So, after 1 week of using, here's some more impressions.
The D18 really plays well with Graham Slee Solo SRG II. From what I know of the Sabre chip it's detailed, at first i was afraid it was going to be a detail monster, or too bright.
The SRG II is very neutral - warm, and from the local forum opinions, some people say it's boring, and some say it's wonderfully warm.
For me it's very neutral, and medium PRAT, kind of jack of all trades.
Now the combination D18+SRGII...
It sounds really really good, at first i thought it's only better from my audinst mx1 + SRGII.
But after 1 week, it's a whole lot better than that. Emi Fujita never sounds better, and i heard more details but presented in a nice way, like how it's supposed to be, instead of just being "thrown" at you so that you could hear it.
That's what happened with the mx1. Rock is also pretty good, it delivers pretty good speed, i tried it with J-Rock, L'arc en ciel, and Mr.Big sounds really great.
Really didn't regret getting the d18, more impressions next weekend, as by that time every burn in myth should be done already.
