Got my Darkvoice this past week. A buddy of mine let me borrow his Sennheiser HD570 headphones. WOW! The sound is amazing. I can only imagine how things will sound when I get my Sennheiser HD6XX from Massdrop in July.
As far as the chinese tubes go... I don't know what you all are talking about my stock tubes sound amazing! I did order some NOS RCA tubes just for the heck of it to see what all the hoopla is about. I don't have any hiss or hum with my stock tubes. Maybe I got lucky I guess.
BuckabooI’m starting to question the tube hype as well. The stock tubes have sounded good to me from day 1 with no hum. I ordered a Tung-Sol preamp tube and have been trying to burn the hum out of it for the last couple of days. Supposedly it’ll go away after 72 hours. I hope so as the hum is very pronounced and makes the tube unusable at this point.
mindhead1I bought a RCA power tube and a NOS RCA preamp tube and had zero hum or noise. Honestly I can't tell the difference between it and the chinese tubes. They both sounded good.
