  It's a snow day for me here, so I'm just relaxing at home burning in my NOS RCA 6F8G on the BH Crack....nope, definitely isn't sounding boring to me!

 

How are you getting on with the RCA 6F8G?

Just cuddle up to the warm glow of the tubes...

Done!

So far I like what I'm hearing...Soundstage is really good, very deep. Nice punchy bass too. Flysweep has been kind enough to let me try out his Mazda CIFTE so I've been bouncing back and fourth  between the two. The bass seems to have more texture with the CIFTE and is really well extended from top to bottom. I'm hearing more sparkle in the high end on the HD 650 with the CIFTE tube as well. The Mazda has this great fluid cohesiveness to the music, really great tube and worth the asking price IMO. I'm hoping to hear some really nice changes with the RCA as I put more hours onto it. RCA is slightly less cohesive at the moment to my ears, but no less detailed. I'll post more impressions later.

At least in the picture they look very exciting!

  Problem is though, I can't decide whether or not I should upgrade my SRG2s to the Ultra-Linear. I LOVE the Sennheiser veil and the dark texture of the 650 so I'm just worried that the ultra-linear with a bit more treble energy might mess up the reason I love my 650s

I did upgrade my SRG2 to Ultra-Linear. All I can say it is a very close to my Pan Am for HD650's. You lose none what make the Sennheiser special.

Thanks! The color is called crimson fire and it's made by Old Masters. About 3 sessions of sanding then staining. Then it was more light sanding and several coats of high gloss polyurethane.

Dxanex...
 
I love the finish on the base also...just wonderful. I'm working on mine now. Walnut with dovetailed corners. I may try to use maple as a contrasting color for the front and back and use walnut for the sides.

That sounds nice! Interested to see how the dovetail joints look...can't wait to see some pics!
 
I think being able to customize the Crack base as you see fit is just another feature that makes it so special. It can be as basic or as beautiful as you like it to be.

I wanted to build a "from scratch" base so that I could put a bottom on it and make it slightly bigger to allow for upgrades and bigger caps.

I know it's not "HD650" talk, but by bigger do you mean taller?  Or are you using a metal plate larger then the one included with the Crack kit?
 
I'm thinking of becoming a Crack addict down the line...

 

[MattTCG]

The base will be 3/4 taller and wider increasing the area of the inside of the base by a fair amount. I'll be using the stock metal plate.

  No problem
 
Here’s another diagram from Brysyon’s BHA-1 manual, although it may be a bit confusing if your using it as visual reference while soldering the wires, just make sure you follow the number scheme.

The HiFIman one makes it a much clearer as the right #3 and left #1 are in real life reversed on the amp's female xlr as shown below.

I highly appreciate the help, it has made the termination of the cables so much faster.
 

   
SPC is what I use on my HD650.  I went from stock single ended, to SPC balanced.  I'm not sure if the material or the balancing did it, but the improvement was greatly noticed.  Most likely both upgrades share the credit...

 
Me and my musical little brother both agree on the SPC part (blind testing via having someone else set up everything behind subject). It has made the HD650 more revealing on the highs, or as my brother likes to put it: "makes the sound feel more alive". Now I'll just wait a bit until I grab a balanced amp in the future
 
As such, here's a bad photograph of my first "bosh job" headphone cable.
 

 
Woo..

Thanks! It sounds even better!

At a show, and just let me say, you had better have $1000 sitting around you don't need before you listen.

 
Could you explain more? Thanks!
