I highly recommend the Signature DC Booster

I purchased my first Signature DC Booster some time ago, more recently I purchased a second and have just placed an order for a third.

I do not wish to come across as a tedious hifi bore, so will not fully list all details of my system. Suffice to say I have a fairly high end system properly set up and sorted with high quality cabling throughout, extensive mains conditioning, professionally installed dedicated power lines, professionally installed additional mains electrical grounding measures and extensive additional signal grounding measures on all my components.

The power supplies I have tested and compared the DC boosters with are;

2 free generic plug top / wallwart style switch mode types;

1 Ifi Audio I Power X (£110) switch mode type used with and without an additional Ifi Audio DC Ipurifier module (£120);

1 Streacom 160 watt (£120) external switch mode pc power supply brick and Streacom internal ATX pc power module;

1 Ifi Audio Elite (£300) switch mode type;

1 HD Plex 300 watt (£500) external linear type pc power supply with HD Plex (£240) internal ATX pc power module;

1 Fidelzer Nikola 2 with upgraded filtered Furutech iec inlet (£800) linear type:

Using either of the free plugtop / wallwart supplies with a Signature DC Booster connected gave performance better than the Ifi Audio I Power X with the Ifi Audio DC Ipurifier connected without a DC Booster and very close to the performance of the Ifi Elite without a DC Booster.

Using an Ifi X Power with a Signature DC booster slightly exceeded the performance of an Ifi Elite. Adding an Ifi DC I Purifier in between the power supply and booster did give a subtle further improvement.

Using an Ifi Elite with a Signature DC Booster gave performance very close to a Fidelizer Nikola 2. Note that, in this instance, adding an ifi DC I Purifier between the power supply and booster showed no further improvement.

Using a Fidlizer Nikola 2 with a Signature DC Booster was a revelatory experience. The further improvement was very obvious immediately.

Using either the Streacom or HD Plex computer power supplies with a Signature DC Booster also showed immediate and obvious improvements in both sound and picture quality.

I highly recommend the Signature DC Booster and feel that it is very good value for money when used with high quality hifi components, high quality audio visual equipment and high quality computers / monitors. in every use case I have tried, they have shown an immediate obvious improvement in sound quality and, where applicable, picture quality. Burning in shows significant further improvements and i would recommend keeping them powered up constantly for several weeks or permanently.

DC Booster Signature

Thanks again for the DC Booster, I am delighted with the unit and feel that it was good value for money.

From first use with my media pc (custom spec, fanless, circa £1500) I noticed an immediate noticable improvement in both sound and picture quality.

As the unit burnt in the improvement increased significantly and now shows an improvement in sound and picture that is very obvious.

If anything the picture quality has improved even more than the sound.

As you indicated that full burn in would take 600 plus hours I am cofident that I will hear and see further improvements.

I think it may be worthwhile for you to add the 14amp option, that you were kind enough to supply to me, to the options in the DC Booster section of your website, as many music and/or video fans will be using computers that have a maximum current draw of more than 10amp.

Best wishes. Derek McKinnon
