Still humming along...

It took me a while to 'bite the bullet' and purchase this for my hifi system; which emits a notable hum from the transformer in the amplifier. I was on the fence for a while after reading a mixed bag of reviews, but, having good previous experience of the ifi brand and also the item being on sale, decided to take the plunge...and well...results are mixed. The whole point was to reduce the transformer hum and sadly this really did not change at all, fortunately the hum really is only a minor annoyance and doesnt effect any music listening at all...so why three stars?...I do feel it has had some POSITIVE impact on the music, notes seem slightly easier to delineate, bass seems tighter, and no perceived lack of dynamics (which I was mainly worried about), so for now the little ifi stays...just like the hum.

Great asset to amplifier

Reduced background noise on the phono stage of the amplifier by 40% also tidied up other inputs slightly reduced volume but well worth the money

Funziona

Essendo consigliato su vari forum e avendo ottenuto buone recensioni, l'ho acquistato per curiosità e per fare una prova pratica. Il mio problema principale era il ronzio dell'alimentatore esterno HiCap della Naim (ronzio dal'intensità variabile a seconda dei momenti della giornata), non molto evidente, ma percepibile prestandoci attenzione in ambiente silenzioso. Per me la presenza del ronzio significa che il componente non sta funzionando al meglio (possibile saturazione del trasformatore), quindi è stato questo il motivo principale per cui ho deciso di provare il DC Blocker. Ho provato a inserire il DC blocker prima sulla multipresa dove è collegato tutto l'impianto (quindi tra cavo della ciabatta e ciabatta stessa), con scarsi risultati. Inoltre mi è sembrato che influisse negativamente sul suono. Poi l'ho inserito direttamente sull'alimentatore (come nella foto di esempio tratta dal sito iFi) e qui ha funzionato subito. Ora, in condizioni normali, il ronzio non si sente più neanche avvicinando l'orecchio all'alimentatore e il suono dell'impianto secondo me è leggermente migliorato in dinamica (forse è solo suggestione, però come minimo suona come prima, non peggio). Però... recentemente ho comprato il Bimby (robot da cucina) è ho notato che, quando questo è in funzione in cucina, il ronzio sull'alimentatore si sente di nuovo (un ronzio intermittente anche peggio di prima). Quindi la mia conclusione è che il DC blocker funziona, ma probabilmente quando i disturbi sulla rete di casa sono piuttosto bassi (le caratteristiche parlano di tensione CC di 1,2 V max). In casi più problematici può servire un apparecchio più performante (ho visto che si trovano DC blockr di altre marche che arrivano a filtrare anche 2,0 V di tensione CC). Il mio suggerimento è quindi di provarlo e vedere se risolve il problema, per me ha funzionato. Quattro stelle perchè il prezzo è esagerato e quando hai il prodotto tra le mani pensi che dovrebbe costare meno della metà.

Didn't work for me

An off-board linear power supply of mine has a low level transformer hum/buzz. It's not transmitted to the speakers so it's not a ground loop problem. It has a fairly large Toroidal Transformer (donut shaped). Reading the reviews and product description it seemed like this could help. It's possible it does slightly reduce noise, but it's so slight it's definitely not worth the £120 outlay, so sadly returned it.I've given it a neutral review, because it clearly works for many people with humming electronics, just not mine. I'm guessing mine is a fault with the transformer itself, but for now I'll live with it as it's not really detectable from normal listening position. The problem with hum/buzz is once you know its there, it gets under your skin.I really don't want to replace my preamp. I purchased a low cost chi-fi clone amp based on a model that costs many £1000s and in all other respects, I can honestly say it's the best sounding preamp I've ever owned.
