Bloody hell. How loud do you listen?

Really? I've run both the 580 and 600 off my Crack and would have the knob up to 2 or 3 o'clock before things were "too loud". Source is my iBasso D10 lineout or HotAudio DacDestroyer lineout.

Not that loud really. Comfortable listening is usually around 10 o'clock. Maybe the gain on mine isn't as high? *shrug* I've got one of the older kits that came with different tubes... but I don't know which ones since the markings are all rubbed off.

And just one more pic of my Crack, with all the upgrades installed......

Yum, that looks fantastic Beef.
 
What is the purpose of that bypass cap on the power supply?

 

[Beefy]

Bypassing electrolytic capacitors is fairly common to improve performance.

How does it sounds after all this upgrade?

It sounds very, very good with the HD650. Each upgrade made noticeable improvements on an already very nice amp.

Does anyone own both a S.E.X and a Crack?  It would be nice to hear how the two sound next to each other.

Try asking at the Bottlehead forums.

Just a heads up to those interested in buying a bottlehead crack.  We now have over 12 people, which means the group buy in on.  For anyone interested, the group buy will be open for one more week and then we will start collecting funds.  We also need a few more people to get on for the speedball discount, so if you already have a crack and just want a speedball, if we can get 12 for that, it will be a 15% discount as well.

Wanted to post my completed Crack and setup. Listening to Alison Krauss "Forget about It" SACD with Yamaha YH-2's at the moment. Plenty of volume and sounds good! Got a pair of HD650's on the way too! Got that Raytheon power tube to try, plus a couple others in the bag.

Could you modify this to have a balanced input/output?

 

[Armaegis]

You could do it if you built a second Crack and used one to control each channel (maybe get yourself a 4-way pot to simplify volume control).

 

[KuKuBuKu]

Can anyone give a general description of how this sounds?

 

[tdogzthmn]

^ It sounds good.  Or is that too general?
