Does anyone know the Alps RK163 potentiometers? - Click HERE for Original Thread

Alps pots for 3€, I wonder how they sound :)

Does anyone know?

Do you have a pic?

Radio Shack has been selling a version of this with a little outboard gear to provide detents. They work far better than the price would suggest.

Hopefully better than the RK09!

Those look like the ones you find in amplifier gear from 200€-400€. Quite a few manufacturers use them (seen them in Pioneer, Sony, Kenwood..:confused: .)

Alps makes pots in all priceranges, so Alps doesn't necessarily = good!

Sobazz, what's wrong with the RK09?

Probably nothing. The RK09 is probably better than other pots for the price, but still I would not put anything like that into an amp... and I don't think I would like to find the RK09 in a commercial unit - even if I had only pad a couple of hundred dollers for it.

I used one in a small portable headphone amp project. Next time I'll compromise size and use a digital pot from Maxim.. the tracking differences between the two channels very simply outrageous!

And then again - it is a cheap pot!
Nisbeth
I knew you'd say that. Have a look here :D

... that cannot be! Simply not possible! They could at least have chosen RK17!

They could have left out the opamps too ... I know X-pre and that one uses a opamp and a tube too. Weird if you ask me.

I wouldn't assume anything at this point. I've heard Nagra is using cheap pot in their $6k preamp because it simply sounds better than anything else they tried. I also had some cheap Alps (different style though) and they sounded better than Black Beauty.

"Sound better"... I objected to the use of RK09 only due to tracking imperfertions... and tracking imperfections - I guess - is a great deal of the reason why people bother buy RK27 or RK40 (maybe even RK50).

Regarding sound quality.. you can always use a series resistor and a cheap pot for shunting a part of the signal to ground. I suppose we agree that it would be the optimal pot configuration, since no questionable pot is present directly in the signal path, thus you can easily use a cheap pot if configured correctly. But the tracking issue is still present...
Peter Daniel
Surprisingly it may sound, but the shunting part is also very influential on the sound. As to the matching problems, you can always get more of those cheap pots and do matching yourself.;)
