Yes. That's how I do it. I found the best option was the bit that has a cylindrical section at the tip with cutting edges at the end and on the sides. Not sure the correct terminology for it, but I think it's designed for carving / reaming.
 

 
Thanks, will these get the job done? http://www.amazon.com/pieces-Tungsten-Carbide-Single-Rotary/dp/B00C9BI1CM/ref=sr_1_1?ie=UTF8&qid=1404956283&sr=8-1&keywords=tungsten+carbide+dremel

Spot on. The right hand end ones are the ones I was talking about. I'm not sure if they are strictly the best option, but they seemed to do the best of all the options I had and made short work of enlarging the Crack's stock volume pot hole.

I just feel like chiming in for those considering doing dremel work. Spend the extra coin on decent bits. The cheap bargain bin ones that come 40 to a set will only cause you grief and mess up your project.

The new DHT SMASH preamp sounded really awesome with the S.E.X and the Crack, now my Quickie is collecting dust on the shelf

+1.  My HD600 + Crack have left me with no desire to upgrade my open-backed setup in the near future.
 
P.S. I love my Orca's, how do you like yours?

Very interested in the SMASH. I'm not familiar with the 4P1L tubes it uses.
 
When you use the SMASH to drive the S.E.X. (um, that sounds a little weird...), do you just set the volume control on the S.E.X. to max?
 
I too own the Blumenstein Orcas. Amazing what comes out of those little boxes! Looks like you also have the sub -- like it?

More Bottlehead goodness.  Quickie and Crack combo, just put Alps POTS in both.  It especially works well in the Quickie, it had real imbalance issues:
 

 
I feel like I won the lottery getting a white top for the Quicke,  Thanks to MattTCG for fabricating the box for the Quicke, it's too nice sitting next to my all Black Crack.

I just double checked my order for this attenuator and email the seller if this is MONO or STEREO.

It DOES say it's the right thing, but just looks so different. I don't think it can hurt to try it - if it's wrong, things will just sound weird I believe. I'd contact the seller to confirm in writing that it's stereo and then hook it up and see. If it's not you can ask for a replacement with his confirmation as proof that you were supplied the wrong thing and tried to check before soldering.
 
Ideally, you could maybe use some alligator clips or some temporary method to hook it up for testing so there's no sign of soldering if you have to return it.

I'm surprised no one else has pointed this out, but from the picture it looks like it's a two-channel series stepped attenuator. See here for a description of the different types.

I don't have my Crack yet i'am still waiting for shipping i guess  have to wait and see if it's a Dual Stereo.Thanks!

I just checked the resistors connections they are in series thank You for pointing that out.

 

[i luvmusic 2]

 Ok i've got a reply from the attenuator seller he confirmed that the attenuator he send me is a DUAL STEREO(Resistors are connected in series for stereo mode)according to him MONO mode usually connected in parallel which is he does not sell.Is this make sense?

Wow, beautiful setup with full of Bottlehead amps. I'm not really sure what preamplifier does? Does it improve sound quality significantly as a DAC?
