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…

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…

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.

Does the SPDIF iPurifier have same technology as the USB iPurifiers?

Accessories

General

SPDIF iPurifier

Does this mean the standalone SPDIF iPurifier is not part of the USB iPurifier line? In other words, is it based on the original USB iPurifier design? Answer: The SPDIF…

How is galvanic isolation achieved and can it be removed?

Accessories

Operation

SPDIF iPurifier

The output of the SPDIF iPurifier is direct-coupled for the precise reasons the customer states. If no isolation is needed this is best. Further, however, in any competent design one…

Is an Laserdisc RF demodulator output compatible?

Accessories

General

SPDIF iPurifier

Laserdisc RF demodulator output is not SPDIF compatible and so will not work with SPDIF iPurifier or indeed any SPDIF input.

Noise is present without any audio?

SPDIF iPurifier

SPDIF iPurifier and the noises without signal with certain DAC’s could well be an issue but if used in a CD player, then can rule in/out so please try a…

Noise is present without any input?

Accessories

General

SPDIF iPurifier

The iPurifier SPDIF does not perform any conversion. However, without input it will normally stay locked on the last sample rate received, if there was no input at all ever…

Should quality digital cables be used?

Accessories

General

SPDIF iPurifier

Any impact from good digital quality cables should be lowered significantly. However, if cable quality is too low then there may be issues at higher sample rates, so reasonable quality…

Should the SPDIF iPurifier un/relock on the signal?

Accessories

Operation

SPDIF iPurifier

The SPDIF iPurifier will follow what the source does, as it offers a bit-perfect pass-through. So if the source drops the signal there will be no output.

Using SPDIF iPurifier with other SPDIF re-clockers

Accessories

Operation

SPDIF iPurifier

The SPDIF Purifier is different from virtually all other ‘re-clockers’ on the market. SPDIF iPurifier kills jitter dead without altering data, bit-perfect (so, for example, HDCD, DTS, and MQA will…

Using the SPDIF iPurifier with an iDSD micro BL?

Accessories

Operation

SPDIF iPurifier

Unless the SPDIF cable is much longer than 1 metre it is doubtful there will be an advantage that is unless there is a ground-loop in the system, as the…

What are the specifications of 5v iPower?

Accessories

General

SPDIF iPurifier

Power: 5v/2.5A. Size: 5.5m x 2.1mm DC barrel. Cable: 1.8m.

Will a higher power supply voltage work?

Accessories

Operation

SPDIF iPurifier

The SPDIF iPurifier is rated to tolerate normal variations of USB voltage, that is it will work reliably from 4.5V to 5.5V. The absolute maximum beyond which damage may be…

Will any audio format stream work?

Accessories

General

SPDIF iPurifier

Yes, the SPDIF iPurifier is agnostic as to what audio format is packed within the SPDIF stream, it may be DSD as DoP, DTS, Dolby digital or conventional PCM (or…
