I just bought D1+ with the full upgrade. I am hoping to use it flat out but if I have to I will pair it with my E9 for my K702 Anniversary and my soon to order HE400. Not sure if I need the E9 at all with both headphones but the added warmth of the tube upgrade, does it color the sound? Will hopefully be a nice pairing for both headphones.
I can report back the difference of the E09K/E17 and D1+ if anyone cares. My source will be a realtek onboard so your opinions may vary from mine.
Really hope the shipping is as fast as you all say I would love to have it by the weekend if I don't no biggie. I am sure Canada Customs will hold it they love to do that with certain items.
