Yeah, I saw that thread and realized that their website has the Paypal button to buy. I already sent them an email asking about the stock, hopefully I'll receive some good news. If not, I might end up with TKD stepped attenuator.

I've tried contacting them in the past and they weren't answering emails either.  Hopefully,you'll be more successful.

I'm a little confused, and perhaps somebody can help me out a bit. I'm trying to plan out a new setup for my office, and so far it's looking like Computer --> DACmagic --> Attenuator --> Active Monitors.
 
If the connection between the DACmagic and the monitors is balanced, I would need a balanced attenuator. Does this mean I would need two separate controls? Would I be looking to buy a stereo pot from Khozmo?
They look great and I'd love to design a little case with balanced ins/outs.

If it's balanced, you'd need a quad pot.

Both versions of his balanced POT look very nice. You in the shunted camp ehhh?

Yepp. The difficulties of keeping the phases equally opposite with a 4-deck pot bother me. I guess these problems become much easier to solve with steppers but eeh. I also like that I can get quality 2 deck pots at the drop of a hat, they take up half as much room, and I prefer the way a shunted 2-deck pot works when providing an SE signal to a differential pair.

Interesting perspectives, Thanx!

What's the difference between shunted and ladder type? ...Was my next question.
Either way, I'll need a quad pot, yes?

 

[slowpogo]

With the ladder type, no matter what position you have the knob in, the signal is only going through a few resistors. 
 
With other types, more attenuation = more resistors, which to purists means the signal is more mucked up at lower volumes.  Or at least the sound will be inconsistent from position to position.

Okay! I guess I'll be ordering a quad ladder pot! Would this be correct if I'm running a balanced setup?

Let us know how it is when you get it.

Sorry - there's one thing I forgot to ask. How do I know what resistance I'll need? I'll be running this between a DacMagic and a pair of powered Mackie MR8 monitors.
I've read that solid state audio usually requires between 50-100k. Is this true?
I've also read that 10k is a common value.

10k, 50k, and 100k are all common values.  As the resistance gets higher, noise becomes more of a concern.  This might apply especially to you if you're using one as a passive volume control.  On the other hand, lower values place higher loads on the DAC and the amp/active monitors have a capacitor on the input, the bass could suffer depending.  All in all any value will probably be fine and 50k is a good middle ground.
