Any benefit to add dual SPDIF iPurifiers together?

Accessories

General

SPDIF iPurifier

Is there any benefit to using more than one of these at a time, stringing them in a series? Will it eliminate even more jitter? Answer: Not really, however, on…

Any problems arise with balanced wiring?

Accessories

Operation

AC iPurifier

In some cases, the AC iPurifier will be used with mains wiring that is balanced, e.g after a balanced transformer, or in some countries, where part of the house wiring…

Are delays introduced with the SPDIF iPurifier?

Accessories

General

SPDIF iPurifier

As the buffer rejects jitter, it’s length in the time-domain varies according to incoming jitter and sample rate. The actual length at 44.1kHz, with no jitter input, will be around…

Are OTG cables similar to normal USB cables?

Accessories

General

OTG Cables

Is this OTG cable compatible as a file transferring adapter? Answer: OTG is “On-The-Go” and is similar to a normal standard USB cable, except an additional pin is connected via…

Are there any compatibility problems with USB?

Accessories

General

iPurifier3

The iPurifier 3 is basically “device agnostic”. It acts as a USB repeater, and is as such, not “aware” of the signals passing through it. If there are compatibility problems,…

Audio sound louder using the SPDIF iPurifer than not?

Accessories

General

SPDIF iPurifier

Perhaps the lower jitter translates into a perceived change in loudness. The SPDIF iPurifier does not change the SPDIF data in any way, except removing source jitter.

Can I invert the polarity?

Accessories

Operation

DC iPurifier2

The provided inverter inverts the wire connections. If you have a centre negative power supply unit and a centre negative device, two inverters are needed. One before DC iPurifier 2…

Can I re-roll the tube?

Accessories

Operation

micro iTube2

The tube GE5670 can be replaced, yes, it is socketed. GE5670 is a premium of 6922 family so unless Bendix 6N3 or WE396A then not worth rolling. Since tubes are…

Can I use it with a Squeezebox Touch?

Accessories

General

iPower

Yes, the 5v iPower can be used with the Squeezebox Touch. One of our customers has reported the following adapter paired with the iPower is a better fit for the…

Can it be plugged into pure sine wave output or same wall outlet as UPS?

Accessories

Operation

AC iPurifier

Can the AC iPurifier be plugged into a smart-UPS, battery backup with pure sine wave output or does it need to be plugged into the same wall outlet as my…

Can it detect what is plugged into it?

Accessories

Operation

DC iPurifier2

On a fundamental level, if there is enough voltage to make active noise cancellation in the DC iPurifier 2 work (around 4V) it works. Excessive voltage past 24V will activate…

Can it extend the USB cable run?

Accessories

General

iPurifier3

A standard 10 metre USB cable will not carry the audio signal properly (it will not work well) but by adding the iPurifier 3, it will actively repeat the signal…

Can the iPower cause a groundloop?

Accessories

General

iPower

The iPower does not have a connection to mains earth – how can it create a ground loop when plugged in directly to mains? Answer: The iPower itself cannot create…

Compliant with safety standards?

Accessories

Operation

AC iPurifier

Yes, it is compliant with CE and all related, relevant harmonised safety standards.

Could I split and feed two devices?

Accessories

Operation

DC iPurifier2

Is it possible to use the DC iPurifier with a splitter connection to feed 2 devices rated at same specifications? Answer: Yes, this is possible, however, it will generate a…

Do USB cables degrade the signal?

Accessories

General

Gemini3.0 Mercury3.0

All cables can only degrade. So with cables, you get degradation for impedance mismatch and signal degradation. The closer the cable adheres to the impedance spec (90 Ohm) the less…

Does it affect signal levels?

Accessories

General

iPurifier3

The iPurifier 3 does not affect audio signal levels at all (it cannot).

Does it contain bi-directional filtering?

Accessories

Operation

DC iPurifier2

Yes, it works bi-directional and will filter the power in these directions.

Does it contain over-current and over-voltage protection?

Accessories

Operation

DC iPurifier2

Yes, it does contain over-current and over-voltage protection based on thermal fuses, if this protection circuitry is engaged the unit may become very hot and will not produce much output…

Does it draw power?

Accessories

iPurifier3

Yes, the iSilencer draws some extra power as it has active noise cancellation, around 22mA (exact amount depends on power voltage). Further question: Is it possible to use with a…

Does it have polarity?

Accessories

General

iPower

Do the pins have polarity, and if so, does it matter how it is plugged into the outlet? There is no ground pin, so you can pretty much flip it…

Does it keep the shield effective against EMI/RFI as ground is disconnected?

Accessories

Operation

iDefender3.0

Yes, ground is disconnected “softly”, that is for RF frequencies the grounds remain connected, but for low frequencies (mains frequency and harmonics as well as 1/8kHz USB packet noise) that…

Does it sound better if in different polarity states?

Accessories

Operation

AC iPurifier

Can you explain that when I use the AC iPurifier in the correct polarity, sound is brighter but in reverse polarity the sound is a lot warmer? All my units…
