Re: The X4 and "THD of <0.000%" -- that's an unusually low THD, yes?

Nice review, but I'm not at all surprised that with all of the bells and whistles of this device, that the most immediate benefit you seem to have gotten is to clean up the bass (unless I missed something).

Wow! Somehow that spec was truncated in my manuscript and it slipped through the entire editing process*. The correct spec is "Total Harmonic Distortion: < 0.0008%"

And, yes, that's what I was hoping for. Still hoping XTZ will offer a configuration for 3-4 subs.

*JA caught it in time for the print edition.

A bit expensive for me, but it looks very pro, thanks to the modular structure. I own an old (well 15 years) CAIRN K3, double mono, also AB but in the future I'll probably swap to a 3 D LAB class D.

As less and less people buying hifi, the prices are going up and up, to exorbitant levels.

Kal, I'm glad you reviewed this. We need more reviews of DSP products, and you are doing your part, for sure.

A question regarding the "treble slope of –2dB beginning at about 1kHz". Was this -2dB per octave, -2dB per decade, or -2dB total from 1kHz to the speakers' natural rolloff?

Kal Rubinson's picture

2db/octave to counterbalance the Silver8's elevated tweeter output.

Thanks for the clarification.

more DSP based products becoming available for the 2 (point 1, etc) channel audiophile consumer.
I would suggest that there is a lot that can be done with respect to speaker and subwoofer placement and tuning to help optimize the sound and integration prior to the use of DSP.
Putting little thought into speaker / sub location and integration and hoping DSP will be a silver bullet cure-all will not lead to the best results.

One can always try out an external EQ/DSP unit with the existing system ...... If such unit has a bypass switch or, if the pre-amp or integrated amp has a processor loop, that would be helpful :-) ........

Kal Rubinson's picture

Agreed but I hope there was no implication in my review that proper setup can be entirely ignored with a "magic bullet." OTOH, it should not be necessary to repeat such basic advice in every report on useful DSP.

Bogolu Haranath's picture

That "magic bullet" may come in the form of an active DSP controlled loudspeaker ....... Who knows? :-) ........

Some are already in the market ........ Some have already been reviewed by Stereophile ........ More will be coming soon to a friendly dealer near you :-) ...........

thank you for your review Kal, hmm, then why not a review of the miniDSP SHD serie which for on third of the dspeaker 4xs price will have more or less same features plus a first class streamer?
