However, later that afternoon I found that a certain low level of hum had returned, and so I then carried out various experimental connections to find out in what circumstances I got hum / hiss. In the event, when I connected the device initially to the radio's output, I was amazed to find that the hum and indeed a certain level of hiss had disappeared, apparently completely. My aim was to eliminate or at least minimize the ground loop hum that I was getting as a result of putting a (very high grade) graphic equalizer between my DAB radio and CD player on the one hand and my powered speakers on the other (with a long lead to those speakers). Having browsed through the reviews here before purchasing, I wasn't expecting this to do the job adequately, or at least to maintain the excellent sound quality that I'm used to. Not ideal, but effective solution and cheap enough to warrant a purchase in my opinion. In the meantime, I think these are a good way to get rid of the problem described.

If I get a high-end AV receiver in the future, this problem may be gone perhaps. It's a shame that I am needing to use these, but I would rather have my speakers intact than 'blown'.

There is perceived clarity to it however and maybe this is good pay-off in certain critical listening situations. Yes, you can turn up the volume, but that will not bring back the sparkle or the warmth to the sound. The top-end sparkle is lost however and so is any 'analogue warmth', this is not so great. The heavy punchy bass is removed, but the sound is definitely 'to me at least' sounds a lot tighter. Just as someone else has reported on here, there is a distinct pay off in the sound quality. In fact, the speakers are completely dead silent, great news then. When I connect this between the speaker and the speaker cable input to the amp, the hum and pop disappear completely. When I want to listen to my other pair of stereo speakers which are powered, then that is when I get a pop and hum when I initially switch on the speakers to the 5.1 Amp. When connected to my passive home cinema speakers, there is no hum or pop, the sound is crystal clear. In my case, I have a 5.1 theatre system which consists of an Amp with a built-in Subwoofer that powers passive speakers. It's a simple device that gets rids of that dreaded pop in your speakers and the hum that goes with it when you turn on your amp and the signal goes to your speakers 'hot', meaning if you are using powered rather than passive speakers with an amp.
