Great post OJ and thanks for reporting back on the choke mod! Sounds like I will have to add that to my list.

Now that I've got to spend time with a fully tricked out Crack I can say that the hype is justified.Д®ager to hear other folks thoughts on this amp. In that past I've only heard stock Cracks which sounding like they were dragging their feet through mud. Staging and dynamics are excellent as well. Other than that the Crack has a great tone that matches well with the Sennheisers (and Beyers). It's the one quality that keeps me from saying this could be an end-game amp for HD800 dorks. The Crack is mostly held back by its lack of resolution and inner detail. I recommend the 5998 tube over all the other output tubes, and then picking the input tube based on your preferences. In this build, I found the treble could range from more laid back to more snappy depending on tubes. The Crack maintains its warm sound regardless of tweaks and tube rolling. Kills a wee bit of hum on the highest end of the knob. Triad 10H 90mA = More dynamic, cleaner sound allows deeper stage to see through. Still slight channel imbalance on low levelsДЄlps RK27 50k= A bit dead up top. TOCOS Cosmos 10k = Much better bass, perhaps getting slightly accentuated/warmish. Stock open frame pot 100k = lacking extension on both ends. Mundorf Mcap = Sounds great as far as I can tell. JAN Philips ECG 6080WC = Lacking clarity. Start to notice slight hardness (think upper mid) in this tube (not necessarily the tube's fault). GE 5814 = Bit more attack up top, more alive. Thanks to /u/DeletetheWeak on /r/headphones for loaning it out to meД«aldwin 12AU7 = Overly smooth, not engaging enough, not enough attack.
