  5. so yesterday this showed up quoting alex... "In a nutshell, the Liquid Carbon is a fully-discrete, fully-balanced, transportable solid-state headphone amplifier that is capable of driving all but the most demanding of headphones - delivering satisfying levels and offering superb driver control for exceptional detail and linearity." lets run that thru fact check for a second. yep... "Liar Liar Pants on Fire" fully balanced? nope, not in the way that any truly differential amplifier would be. (like any of the super symmetry variants) and absolutely no common mode rejection. fully-discrete? nope not really, see the single ended to balanced converter in the schematic below http://gilmore.chem.northwestern.edu/lc.pdf so much fail in one package... can the stax mafia do better, you betcha. board in progress now, will run up to +/-24V and bolt to a heatsink. So say a liquid gold clone for about $300 in parts. people, why do you buy poorly built crap like this. Buy Schiit, or Audio-GD or many other high quality brands for a lot less money.

  6. If it still works I'd just run it until it quits. No reason to care if water is getting into it and shortening its life.

  7. much more better version now above. fets on the back side. just about 100% groundplane its about $15 per channel could use the caddok resistors for the .47 ohm, and double the price of the amplifier

  8. The Lambda Nova is excellent, nothing short of it. A guy came from Denmark 10 days ago to pickup an amp in person and we naturally made whole listening session out of it. He compared pretty much all of the Lambdas and the LNS was a stand out success. Funny though, he wanted to try the SR-404 (as he has one as well) and my reply...which one? I have three.... SR-404, SR-SC1 and SR-404LE...

  12. Sweet. Thanks for the explanation about the voltage jump, guys! Pictures attached to this post. This was my first time working with external heatsinks. I underestimated the difficulty, and ruined one sink trying to hand-drill it. Total fail. Luckily, I discovered that a colleague owns a Tormach PCNC 1100, and he was kind enough to invite me to his workshop and let me use the machine. A gorgeous device, let me tell you. It made short work of all the drilling. Then I hand-tapped all the holes (I think the Tormach machine can tap holes, but I wasn't sure how to keep the oil flowing and the taps clear of gunk for this operation). The heatsinks themselves took some finding. They are Fischers, 10mm high by 300mm long, with 40mm fins, part SK 56 100 SA. High quality, and hard to find in the US. With 10mm standoffs, the entire amp fits nicely into an enclosure just slightly larger than 2.5U. (I also tried sinks with identical dimensions from HS Marston, and they sucked: all extrusions I received were crooked, and there was no way I could have bolted angle brackets to them.) The rest of the chassis was done by FPE. In retrospect, I wish I extended the top and bottom panels to overlap the sharp edges of the heatsink fins, with large rectangular cutouts so air could still circulate. Still, I'm happy with how the case turned out. If anyone cares, I'm happy to share the .fpd files. Because FPE does not do anodizing, I had to have the panels made in two steps: one run before getting the pieces to an anodizer, and one run after. The circuit itself was easy to assemble and adjust. No trouble from the Toroidy transformer. Overall, the amp runs a little warm to the touch (at 20mA output): cooler than either my KGST or mini-KGSSHV, though we'll see how it fares after more than an hour (all I've listened so far). Many thanks to @mwl168 for the group buys and build notes, @sorenb and @jdineshk for the capacitor group buy and help, @vilts for making the spectacular titanium knob, everyone else who answered questions and provided inspiration, and many many thanks to Birgir and Kevin for making all this possible in the first place.

  13. The battery will be a sealed unit, so no worries there. If it kills the circuit board tomorrow, then you got one more day out of it than if you replaced it today.

  15. I have music! Pretty obvious this is something special. It was pretty easy to adjust, and the circuit seems fairly stable so far. Still, something strange is going on: when I turn the amp off, all offsets jump to >250V, and then slowly down to 0. It's looks like the HV rails short to the output. I don't think this happens with my KGST and KGSSHV builds. Is this expected, or did I fuck something up while wiring the amp?

  19. Kerry's work with foam might be a good answer to replacing what's inside the 009 pads. At the very least you wouldn't be paying 250 for a pair... I might implement a bootlegged version of this idea using old 007 foam . Thanks for the inspiration Kerry!

  20. That's one of the reasons why I no longer sign in on HF, and haven't done so for sometime. I do occasionally look on that site though to see what crap's been written, also to have a laugh.

  21. Yes, you should see 2 test points next to each of the two 50 ohm resistors on each channel.

  22. Test in volts not milliamps. 1V is the setting for 20mA.

  27. I got bored being too far ahead on Azure Coast in Project Cars and decided to turn around and ram Grahame, which got me DQed. But it did let me catch this shot of Brent stealing a road sign:

  32. I actually listened to these headphones on Friday. They are very quick and detailed, but smooth, with a somewhat forward presentation. I preferred them greatly to the withdrawn, distant sound of the HD800S I compared them with directly. There seemed to be a slight dip in the lower mids that made male vocals feel a little buried, and the bass punch was not to the level of the best planars. Soundstage size felt a bit limited for a TOTL headphone. They are fairly heavy, but clamping force is light, and the pads are well done, so I didn't notice any comfort issues. Overall, the detail they produce puts them in a very high class, and it's all personal preference from there. They wouldn't supplant the HE1000 as my personal favorite headphone, but they may be just what others are looking for.

  33. So cool that you both remember Austin Carr! Should've been the next great guard ... Michael Jordan before there was a Michael Jordan. Maybe Isaiah Thomas is more accurate. He was never quite the same after he blew out his knee... Still, a very good player for us, and as mentioned, is Mr. Cavalier.
