Having done more than a bit of experimentation on this, can i suggest you avoid silver plated contacts that aren't sealed from the outside atmosphere. Silver oxide might be conductive, but it's still worse than hard gold plate. Grayhill make great switchgear.karatestu wrote: ↑Thu Mar 11, 2021 5:29 pm
Then we get on to the expensive bit which is stepped attenuation. Some of the prices are eye watering for the kit and ready built versions. Some of the resistors are very pricey especially the Audionote silver tantalum non magnetic jobbies. Can't afford them. I don't want a kit or ready built for reasons I will explain later so had a look at switches first. One or two pole ? That would mean choosing between stereo and mono. I can't decide yet, still torn in two about that. Do I want two volume controls? Could be handy for any balance problems I suppose but two mono switches cost more than one stereo switch.
Yeah, most of the time less is more, but occasionally more is more. Here is an abbreviated version of my voyage.karatestu wrote: ↑Sun Jun 27, 2021 7:23 am I haven't bought a stepped attenuator yet, been too busy faffing about with speakers and power amps
As to introducing a buffer is concerned- I would only do it as a last resort . Adding components goes against my less is more philosophy (which I borrowed from RD).
If I ever did use one it would have to be as simple as possible and unity gain as you suggest Rex
Yeah, I'm well pleased with it. It has been a nice little upgrade for the little AP20. Silver wiring next I think
