I've been interested in the Schiit Magni amplifer, along with the Schiit Modi DAC. I purchased them and they paired well with my Hifiman HE-400, but as the Magni is something of a budget amp that hits beyond its price point, they had to cut cost somewhere.
That cut game with the volume potentiometer. There's very little play on the volume pot, especially at a fixed gain of 5. I was only ever able to get it to around 9 o'clock before I was comfortable, but moving just a little bit put it out of my range.
Enter the Harrison Labs 12 dB RCA Line Level Attenuator Pair. I bought these, plugged them into the back of my Magni's RCA ports, used by Blue Jeans Cable LC-1 RCA cable with them and into the Modi and viola - I instantly had more play on the volume knob. I could get to around 3 o'clock without it being totally uncomfortable, and small turns didn't result in drastic changes.
Best of all, I was unable to discern any loss of quality in what I was able to do in regards to blind testing.
It indeed does the trick.
I have no idea why people pay $$$$ for these crazy passive systems, when a simple resistor-divider devices like this does the trick (without the associated impedance issues, since the higher-impedance output is right next to the amp, and has very little capacitance to drive).
This receiver/amp makes using the Harrison attenuators easy. It has rca preamp outs right into main amp in on the back of it. So, I pulled the little pins making those connections, used two very short patch cords along with the two attenuators, and put the -12 db in between the preamp out and the amp in. It works perfectly. It gets my volume control that much more off the floor of it's range where it's not all that even between channels (like most of such pots that control volume).
IF I had any need to turn the -12db on and off with my remote control, I could have put these on the good old Tape 2 monitor and created a loop where, when I selected that (along with whatever other input) it would loop the signal out the back and back in again, minus the 12db, and have it as a handy on and off for the attenuation. But, I don't need to turn the attenuation on and off. On all the time is great.
So, works as advertized for me. If there is any degradation in sound, I surely cannot detect it and I'm pretty picky. These are excellent.
I bought these to attenuate my Hafler DH-500 amp with my Carver C-1 preamp that are both in mint condition. These worked perfectly and didn't effect the sound output in any way other than simply knocking down the amps output by 12 DB.

Very simple device that worked very well. Older TV line level out was too high for amplifier which had a high sensitivity. The volume level was either too low or too high. Read morePublished 29 days ago by Amazon Customer

The product worked just fine. My only issue was the shipping cost. Every package of two had a separate shipping charge. Yet they were actually all bundled into a single box. Read morePublished 14 months ago by Bigguy
12 db is not alot of attentuation. Double what you think you will need.Published 23 months ago by southman
Perfomed As Expected.
In the consumer realm, most component home media players(CD players, DVD players, VCRs, TiVos) have a nominal output of 2-3Volts RMS. Read more
Got these to reduce the output of a mixer to feed into a digital recorder. I found it only reduced the level by roughly 6db. I suppose they are calling the pair 12db? Read morePublished on April 22, 2014 by Glynne
