Wtf are you saying? It would have been a 32 seconds long process for I to make that tube in line. Important: you've got to get matched tubes with golden pins at eBay. The gain are determined by the space between the two "plates" in the tube. Looks like all normal audiophile members only have cash today. It's scientifically significant to observe that not a single man on this planet have both brain and money in the bank to purchase the product I love. Exchange tubes! Buy 10-20 pairs of NOS tubes + a pair of balanced super-tubes. Wonder how it would sound with a super XLR between my Magic plus and this genuine product? Would've bet that the 4pin output from this beauty, class A etc etc... will yield absolutely astonishing quality sound in the Senheiser HD 650 terminated with the cheap upgrade phones cables By American Nordost's best opportunity: Heimdall 2 (inspired from Norwegian mythology - just as Schiits products). I'm living 1900meters from where the best of the best are made by proud Norwegian nerds with super-knowhow about electronic. If you are able to make a product that suits the Norwegian (+Albanian;-)) power system, then you're going to make it! ELECTROCOMPANIET (Q.JONES + THE KINGS CHOICE ON BAD) ARE ONE OF THE BEST BRANDS. HEGEL FROM OSLO KNOWA SOMETHING 'BOUT BASS CONTROL. XDUOO V20 = THE MISSING LINK TO WARM UP THE sound pictures.
