I did more tests with those new USB gadgets :
For a short summary, all those small USB gadgets they all worked in various ways. Both Bonnes Note Dressing (what a name) and the AQ Jitterbug is USB2.0 device; both iFi iSilencer and iDefender is USB3.0 devices.
Bonnes Notes Dressing (US$55) and the AQ Jitterbug (US$49)
The 2 Bonnes Notes Dressingand the Jitterbug does make the sound a bit more organic, but not on the same class as the iSliencer (seems like their ANC actually works). I tends to prefer the BoneNote slightly more than the Jitterbug, the BoneNote just gave a touch more fineness in sound.
iFi iSilencer (US$49)
The most significant is the iSilencer, it really lower the background noise and make the background darker, sound (especially the mid range) is defectively more organic, also the treble is quite a bit smoother.
Use Multiple of them? (on the same PC on different USB ports)
2 x Bonnes Notes: didn't have much improvement at all over the single one, this is a bit weird.
2 x Jitterbug: a small additional improvement was heard when the 2nd one is installed, a little bit more organic sound.
2 x iSilencer: again a small but quite nice improvement was heard, dark background still, it makes the music notes jump out to you.
I now have 3x iSliencer plugged in on the same PC, the first one gave the most improvement, however each additional one does bring another nice but small improvement.
Lastly, nearly forgot, the iDefender is for a different purpose: to add external power input when there is none. I am using it with iFi iPower to create a really nice low noise supply. So far this combination has already better my AQVOX USB power supply and a couple other Linear Power Supply.
Scores (out of 100):
60 Jitterbug
65 2 x Jitterbug
65 1 x Bonnes Notes Dressing
65 2 x Bonnes Notes Dressing
80 iSilencer
88 2 x iSilencer
Note: As those are much cheaper gadgets, the points scale is not the same as the original USB hug devices tested. |
