  Quick question about the Cardas Quad Eutectic Silver solder - what is the consensus on its impact on sound (if any)? Any advice on how to use it properly?

 
No impact at all to sound. But it is easier to control than some of other solders (mostly due to the smaller diameter).
 
Note, if you get the lead free, it has a higher melt point, so you need to watch your technique and if needed, use heatsinks to make sure you don't toast anything important. If you are new to soldering, get the leaded variety.

Finally managed to get hold of some Mundorf 100uf's to roll and have been happily swapping backwards and forwards between caps for the last few hours...

First of all I have to say it is a blast building Bottlehead gear.  I've built several kits over the years.  Couple of Foreplay 2's, Couple of Foreplay 3's, Paramours, SeX Amp, Couple of Cracks SeYy Speakers....probably more I'm forgetting.  Done all the mods to all the gear as well.  Fantastic quality and just fun to make.
 
I've finally found the magic configuration for my BH Crack here in my living room.  Some will probably shake their heads in disbelief but I'm telling you it works for me.
 
Bottlehead Crack w/Speedball
Western Electric 421A
Orange label RCA clear top (I'm sorry my mega buck, rare, made by aliens 12AU7's don't compliment the 421A like this one Clear Top I have).
Sennheiser HD650
Fiio E17 plugged into 2012 Mac Mini running Clementine.  I've found if I go to the Spotify app somewhere and select an album and create a new playlist with it then play it back through the Spotify plugin in Clementine with the output set as Audo Sink (OSX) then it sounds crazy, ridiculously, stupidly amazing.  Listening to Amber Rubarth "Sessions From the 17th Ward" and I've never heard it this good.
 
If you haven't experienced the Bottlehead Crack you absolutely should.

The Mundorfs and I are still courting 

 and while there are noticeable differences between the films caps I have on hand its not particularly as clear cut as I was expecting or would like considering the price differences.  
 
I do think its safe to say that anyone fitting Mundorfs won't be disappointed and will have a very nice sounding Crack. Also I have kept my Teflon bypass in place today and they will be masking some of the differences so tomorrow (err later today after I have got some sleep 1 am here) the Teflons will come out and then try again with just the 100ufs on their own.

I forgot to ask which series Mundorfs you're using?

Looking good!! Waiting for your impressions.

Anyone of you guys used this TEAC - UD-H01 DAC with the CRACK?Thanks!

Looking good!! Waiting for your impressions. 

Nah I'll hold back my impressions. I'll let you hear it for yourself and make your own impressions so you won't be influenced by my words

They are the M-cap 400v 100uf versions.

That's what we installed in @atsq17's - I thought they sounded great (with no comparison to any others because I built it from scratch with the upgrades in place)

Fitting a choke and replacing the last electrolytic capacitor with a film capacitor makes a nice improvement to bass extension.

Hi Jamie:
 
I got 2 chokes and a film capacitor. Unfortunately, I don't know where it goes and neither does my friend who assembled it for me. Can you help with a photo or a brief note as to where all these things go? Thanks.
