Fully assembled and tested by a paid professional about two months ago. I would rate the condition 9 due to it is unrefined condition. Total used time is less than 10 hours.
The Bottlehead Crack is the perfect complement to high impedance headphones, especially Sennheiser HD600, HD650 and HD800 (which is also for sell here) headphones. Numerous golden reviews if you google. You won't be disappointed. I'm selling all my headphone equipments and switching to speakers.
Any questions please message me.
Thanks for looking!
