Just read this from Nelson Pass very carefully and let it sink in, he can’t make money from saying it, in fact it would hurt his preamp sales.
Then go and buy a $49 Schiit Sys passive preamp, about 100 x less than your Edge S-1 preamp
I'm not sure if the suggestion is to add the Schiit to my set up or dump the Edge altogether and just use a passive preamp. And I still do not understand why this preamp is made this way. It must be good for something on its own. Just Edge amps? Or other amps designed like an Edge? I guess I would rather know what amps would be a good match and get one rather than adding another preamp.
I'm not trying to denigrate the advice on the attenuators but more than one audio dealer told me a big no on those. Of course everyone has their view.That’s because Dealers make very little money selling Rothwell attenuators. I would highly recommend trying them for yourself, they are not expensive.
