I'm surprised no one posted any recommendations for passive controllers.

Studio Monitoring SM PRO Audio Nano Patch - Audiolifestyle

I have never used it before though.

I don't find schematics anywhere and I don't own one, so can't help much on how to do it. I would contact the manufacturer and see what they say. Using inline attenuators, etc. is just a band aid and doesn't address the core problem of too hot of an output. Of course it is easier...

CD output is supposed to be standardized at 2 Vrms (IIRC, but I sometimes confuse Vp-p, etc.), but many manufacturers violate this.

I had some Goldenjacks when I had a stupidly oversenstiive Graham Slee Solo, they worked very well, but I sold the Solo and gave the Goldenjacks away to a fellow headfi member.

I agree. With my previous tube pre I used all three brands and the Goldenjacks had the least impact on the sound. The Harrisons fogged up the mids and the Rothwells lopped off the top end and added an odd warmth to the highs and mids that killed my system's resolution.

Still, I agree with Duggeh that any attenuator is a compromise, though the Goldenjacks the least so. Whichever offers a money-back guarantee may be the way to go. I still have a set of the 14 db Goldenjacks here that you're welcome to demo and then send back if you want.

a well implemented design should not cause any sort of degredation.

I have to look at these claims of "massive roll offs" and such with a bit of skepticism.

Your claim of "should not" is what I thought before I bought any. My claim of killed treble is what I found after plugging them in.

Whether its down to a dirtying of the signal path, the creation of a catastrophic impedance mismatch or magical goblins I do not know but the effect was not subtle and nor, for me, was it tolerable.

I've probably got one set still in a drawer somewhere. If I do then olblueyez can have them for the cost of postage.

I have used several different versions of Audio Diffmaker, it is pretty good but it is still a bit flaky. It can find differences between two identical files, especially at the start of files. It would be almost as easy to do two recordings, one attenuated and one not and compare the spectra by sight.

Yes, flaky, as in it does not always work correctly for me, now it may be the interaction with my particular systems but I have had trouble with it on two different PCs. This is a shame as I really like it and what it represents but today I loaded two identical files into the latest release and it still found differences between the files. I even tried it with the same file loaded twice !

So when I am looking for concrete proof of small differences I am not sure I can trust it's reliability.
