I have the Bifrost matched with a BH Crack.  I love my setup by am jealous of how neat those 2 look stacked.

I love the look of this.  The black bell looks really good.  I am waiting for my walnut headphone stand to stain the base so I can try to match the color.

Now this is just my option and I am not a Mac user so...For my setup I use Foobar2000, output to WASAPI event mode and don't turn on any DSPs and volume is at 100% in player.  So it basically means your are streaming bit-perfect to your DAC.  Any software or plugin that make the sound "better"...

I did A/B on my Uber version and I honestly can't hear a difference, mind you I don't have 32/192 content.  USB is convenient for devices that have no optical out like most laptops.  If your macbook has optical and you are tight for money I am sure you will 99% happy.  The last 1% I blame the...

Why not do this taken from the Crack FAQ over at BH forums  ******************** 3.  I can barely turn my Crack up at all before it's far too loud, what do I do? Remove the white wire from the left RCA jack at the rear of the chassis.  Solder in a 270K resistor to the solder cup on that...

It's a good idea to have spares of both tubes, that way you can easily figure out if it's a tube problem or not. If the noise is only when you tap on the tube then it's probably tube but you also said that some bass notes cause the problem so I would make sure all you solders are good.

LOL, this has got to be the sketchiest setup so far.  And you are telling us you got shocked?  No!, really?? Just messing with you.  I'm sure you'll enjoy the crack once you get RCAs and working headphone cables :)

  This confuses me too.  I understand that you took just 1 cable so you have either a left or a right plugged in. The only thing I can think of is either your cable was carrying the crosstalk and not the crack generating it(?) Or, you have something wrong with your wiring and 1 channel is not...

You can check their delivery status page, http://www.bottlehead.com/et/deliverystatus.htm They only update it once or twice a week but it gives you an idea on how long it should take. They seem to be a bit longer now because they are in the process or just completed a massive group buy that...

It would seem like it is not. Refer to this thread for compatible tubes http://www.bottlehead.com/smf/index.php/topic,663.0.html

I have these cables.  I think they are fine.  No need to pay big bucks to get a good cable.  At least that is my opinion.

I saw this post together and got excited as I was also waiting for some tubes from W0lfd0g. When I got home I had a pretty box waiting for me :D   Put in the Tung Sol 7236 and RCA clear top first.  Listening right now and it sounds great although A/B comparison at this point will be to hard. ...

Edit, on mobile and can't seem to quote posts properly. This is re: Doc B's comment. Just to be 100% clear, the smoke came from the crack and not the tube. The tube is intact on the outside. There is quite a lot of glass moving inside and you can see the 2 outer copper wires have glass broken...

As long as it doesn't go over 9v. Mine would slowly climb to a few volts then back down to 0. You should do the mod the guys from BH posted in their forums. You simply connect the 2 unused terminals from TRS jack to the bottom closest to plate. This will keep voltage at 0v when you power on.

That part of the instructions confused me as well. As long as you have checked for smoke you can safely unplug it, turn it over, put negative lead in t12, turn back on and take positive lead for the terminal readings.

From the crack.  Got a message from Doc B. saying it's probably a bad tube.  I've been listening for about 1 hour now with the stock 6080 and no issues, other than my head bobbing to the music :D

I just tried the tube again and was keeping an eye on the tube and board.  Everything was fine up until about 3-4 minutes.  Smoke started gathering in the top right corner where the power is fed.  The plate was propped open on top of the box as I dont want to put the tube with all broken glass...

So I wanted to try a used 5998 tube that I have and after a few seconds of turning it on and both tubes glowing there was smoke coming out the case.  I put the stock 6080 tube and had popping sound when plugging the headphones in.  Well the popping I figured would be a bad ground connection as...

Pictures soon, first I have to stain the base. I also painted the plate and bell but messed up the bell a little :|. As long as she sounds fine I don't mind a few scars.

I'm happy to say that my Crack is built and working :D Took a few hours to troubleshoot what end up being a cold solder joint.  All in all the build was fun and very straightforward.  I soldered more on this build than the rest of my life combined.  I ended up retouching some of my solders by...

You guys are terrible :P i am starting to think the non audio version of crack might be a cheaper hobby :) thanks for the advice.

  Thanks Loqah, actually I want to build stock first to get more OMG moments :) and to make sure I built everything correctly before going with Speedball.  I actually found the post I was referring to.  Sorry it was over at the BH here: forums, http://www.bottlehead.com/smf/index.php?topic=1870.0

I received my Crack and Speedball parts yersterday.  In the process of building it now.  I remember a post from a member that had suggestions for new builds that would get the speedball installed.  A few things to make the speedball upgrade easier to install.  For the life of me I cannot find...

Doc B, do we get an email when product has shipped? I've been refreshing the delivery status page madly everyday and last update was almost 2 weeks ago. On top of that the crack status was shipped up to the day before my order :/

If drizek plans to upgrade to HD800 then I would suggest getting the next step up for a DAC to keep the price ratio closer.  Maybe a Schiit Bifrost? Or wait to see how much you'll like to build the Crack and get the Bottlehead DAC once they release it? ;)
