OK, tubes have over 10 hours now, the initial excitment settled down a bit....
What is clear at the moment:
1) They have much better, controlled bass which is no way boomy. I have Klipsch Heresy 3 and REL Strata 3 sub... At the moment I am biased to use sub as triphonic system, I just feel there is enough bass for me and for the room (20 sq.meters).
2) Midrange is more open and sweet. I feel it might become (I hope so) more defined.
3) Highs (trebles) are delicate, I wish they becom more articulated and airy.
4) Soundstage is big improvement over my previous tubes, it is just amazing.
At moment I find sound of these tubes very relaxing and addictive to listen over period of time.
Funny enough I have Senns 650 with Stefan Art cable and subversion of headamp called Zana Deux Micro (at the moment available in Russia only). I liked the delicate and airy sound and preferred it before to my speakers rig, now I prefer the sound of speakers, find headphones a bit lacking resolution.
Tubes are revealing to show a bit mechanical sound in records which were made in late 80s and they sound lively with records from 60s, it could be my setup though (Thorens 124, SME 3009 and ZYX R50).
I will post another comments when tubes will be over 100 hours to see whether sonic presentation has changed.
