Folks, no matter how this knob measures, it sounds excellent. I do not care what you think about its parameters, they are just fine for me.

Jonathan,

I can imagine that a stepped attenuator with bulk metal foil resistors must sound wonderful. They are my favorite resistors (especially the nude TX2352s from Texas Components).

Would you say that this attenuator is the best there is?




Best

Yup. Distortion measures lower than a normal pot. Sounds OK, too .

I do not know. I have
no experience in testing different volume knobs - and frankly I do not believe that different audio knobs will sound differently when using ELMA rotary switches.

I do know that some volume knobs costs 100s of USD which make the 160 USD for a stepped pot sound cheapish. But I will not play that game.

That is why I would never try to make a living by audio, though I have had very interesting design and project co-operation with US and japanese customer, concerning highly specialized industrial technology.

In some parts of the world, labor would be the very least expensive thing (as most multinationals well know). But that is not the point.

The point is that if you paid for your house the same relative price of certain high-end gear, I'm sure your house would have everything your heart desires, including Pamela Anderson.

Anyways, I should think the readership here deserves a bit more technically literate answers to their questions than the same old labor/price routine. Otherwise, I do not see much difference between, say, a gaincard scam where USD200 worth of parts and labor is going for a retail price of USD2,000 and a preamp with USD2,000 worth of inputs selling for USD20,000.

At least for low-level signals, I find the combination of SMD bulk metal foils and rebuilt Shallcos to work well. But maybe there is something better, and I simply don't know about it. You tell me .

Folks, just so that you know and understand. We use Shallco switches in our preamp. They are VERY hard to turn. In fact, without a real knob, it might well be impossible to change the switch position. A small knob might work, but it would be very hard to turn, because you need a large radius on the pot to get torque multiplication. A larger radius usually means more depth, as well, and the added inertia of the knob, smooths out the rather bumpy switching from step to step. It just feels better, that's all. Now, what is wrong with that?

Finally we're getting somewhere. Now, how about those measurements?

My ultimate test 'knob' is a pair of locking pliers that grabs onto the switch shaft. It works pretty good, and Radio Shack can supply them. Looks a bit funny, though!

Hi John,
Sorry. You're a bit late with that. It's a popular fashion in places already.

Looks retro, don't you think?
