The GS-X mk2 arrived today, therefore some first impressions:
Setup is: jriver or foobar --> Invicta DAC --> Crimson RM Audio balaced --> Headamp GS-X mk2 --> HD800 (single ended standard cable (balanced DHC Molecule SE ordered some weeks ago)).
It's just a comparison between the above setup and what I used during the past months: jriver or foobar --> Invicta DAC --> HD800.
Be aware that the Invicta built-in headphone amp(s) are excellent and better than many (most) standalone desktop headphone amps.
Listened to: Kari Bremnes - Erindring / Jethro Tull - Aqualung (40th anniversary edition, 24/96) / Fotheringay - Banks of the Nile / Gene Clark & Carla Olson - So Rebellious a Lover / Neil Young - Live at Massey Hall (24/192)
The main improvements, which where immediatly evident:
- lower mids and bass
- Authority. I have met this word in other descriptions and reviews. I never really understood what the writers meant with "authority"... until I switched the GS-X mk2 on!
It's a significant step up compared to the previous configuration - and I was not even using the HD800 in balanced mode.
A minor thing, which could be improved is: when the pre-amp is switched on, the headphone outs should be muted. At least I would prefer it.
Excellent work, Justin. Thank you very much!
