It definitely can be done much cheaper, but at that time I didn't want to be bothered with developing another circuit.

Id do it but i don't want to step on any one's toe's. Is any one interested in such a device ? 450$ is a little steep.

I for one would be VERY interested in a remote volume setup that I could DIY for less that the known kits - hopefully LOTS less.

It's not only steep, but DACT attenuator is nothing really special either.

I already mentioned that the better volume control is under development: http://www.diyaudio.com/forums/showt...425#post839425

I'm working on it with Veteran, who does programing and development of control board, pictured below.

This setup should be able to compete with any currently available attenuator kit on a market, the price will reflect it, but as usually, it will be still affordable.

I am very interested in this type of control, as I said before. I have this vision of being able to touch a button from the comfort of my chair to adjust the volume on my chipamp. But, I like the sound of my chipamp and I don't want to loose it to the innards of a volume control chip.

I have seen some very simple motorized pot setups that didn't cost much, but the weak point was, of course, the pot.

The other 'but' is that I got in to chip amps because of they are phenomenally inexpensive. If I wanted to spend hundreds of dollars, I would buy something with a warranty so I had someone to yell at if it didn't work properly. However, for me, the fun of building a working amp with descent preformance from junk-bin parts and a couple of hours is right up my alley. $200 for a volume control would be more than double what all 3 of my chipamps cost - $450 would probably exceed my entire investment in hifi.

So, guys, I am looking for a good, CHEAP remote stepped attenuator solution - probably an oxymoron, but then so am I.

Jess

Yes, there will be LED numeric display, as well a volume knob and remote control. No options here, it will be standard.

Nice work
We already know almost everything about new amplifier could You tell what resistors are used in amplifier?
& am thinking to order several different type resistors for experiments very interesting to try Your favourite combination.
