It "shouldn't" have made a difference...................
.................but it did
It will get you labelled as a deluded nutter...but you get used to that!
Good job.

Ps. It's good to see you back.
Why shouldn't it have?
If you have a noisy mains it is a great, cheap and well made block for not much money. Its effectiveness is system/mains dependant but I've yet to experience the sapping of power/stiffling of dynamics with amplifiers some have quoted.
If you have a well regulated power supply such as your hicap the tacima (or similar products) probably won't do to much but for any other pieces of hifi with often tiny supplies and regulation the addition of one can make a surprising difference. I even use one with my AV receiver to good effect even though supply regulation is on the large side.
The issue with things such as mains conditioners is that there are a fair few variables which makes it difficult to get a concensus.

CNO, thankyou, yes been a while, had a bit on my plate so to say and not a lot of time for the music yet alone forums. Yes I do think I am a standalone looney.
I am not dismissing the effect of tacimas on TV's, CDP's amps etc, in fact I do believe I have championed them in the past, and still do to that matter. But I could not understand how on earth a nas and sonos bridge would benefit......still have no idea but they definately do.
Yes I do think I am a standalone looney.
Make no mistake my friend, you are not alone.

No there are plenty of loonies about. 
But nobody should characterise you as such. If you hear a difference, you hear a difference. Whether that's a perception rather than an objective difference is something that could be investigated but if it's "real" for you that should be fine for everybody. Personally I find it hard to understand how it could work in the ways you mention but I'm of a scientific mindset and am sceptical about these things. If you have a scruffy mains supply then it can only be a good thing to make it less so. I've got a mains conditioner and as far as I can tell it makes not the slightest difference.

Moved my NAS drive and sonos Zonebridge during a clean up and plugged them into a tacima. More detail, more bass, not sure how or why but its definately better. even the OH noticed, asking me how much Id spent because the sound was clearer......
