Recommended Components: 2017 Edition Signal Processors

Signal Processors

A

DEQX PreMate D/A preamplifier/equalizer: $4995
In a field where, as KR puts it, "all automatic EQ systems conflate speaker correction with room correction," the DEQX PreMate stands out: In use, this DSP engine begins by measuring and analyzing the speakers—in exclusion of the listening room, to the greatest extent possible—then generates filters to correct frequency response, optimize time alignment, and, if desired, create a customized active crossover for that speaker. After that, the user can, if he or she wishes, completely discard the speakers' internal passive crossover components (although that's not required). Bass management and, ultimately, room correction can also be implemented with the PreMate: icing on the cake. The PreMate Incorporates a volume control and switches for choosing—or not—from three preprogrammed configurations. The usual variety of connectors provide S/PDIF, AES/EBU, TosLink, and USB inputs; there is also an XLR input for a calibrated mike (included), plus a variety of analog outputs, to use for the main stereo channels and subwoofers. Apart from noting that "the learning curve is steep," KR was unequivocal in his praise for the DEQX PreMate: "It made my very good speakers undeniably better, smoother and cleaner." (Vol.37 No.12 WWW)

Dirac room correction system: Full version: $720.85, Stereo version: $431.40
Of course, the sound quality is dependent on the hardware in the system, says KR, but the acoustic transformation capabilities of DLRC are well beyond what is found built into most processors. (Vol.37 No.5 WWW)

Paradigm PBK: $99 ★
An adaption of the formidable Anthem Room Correction system used in Anthem's Statement D2 processor, the PBK includes USB cables and a microphone, and will work with up to four Paradigm subwoofers. While easier to use and considerably less expensive than either the SVSound or Audyssey devices, the PBK's subjective results were "no better or worse," said Kal. The PBK provided "a huge improvement" in the bass performance of the Paradigm Reference SUB 15, however. "The PBK, the SUB 15's obvious mate, is a bargain," KR concluded. (Vol.33 No.1 WWW; also see JI's MartinLogan review in Vol.40 No.1)

miniDSP nanoAVR 8x8 HDMI audio processor: $249
Taken to task by KR for its ungainly bass-management configuration—but nonetheless praised for offering real hands-on room EQ, like the miniDSP 10x10hd—the nanoAVR 8x8 now features reworked software and DSP firmware to allow standard bass management. (Registered owners of the previous version can download the update from the miniDSP website.) KR confirms that the changes address his criticisms: "I can now highly recommend the miniDSP nanoAVR 8x8 for use with high-end pre-pros that lack EQ or have limited or inadequate EQ." (Vol.37 Nos. 7 & 11 WWW)

Deletions DSPeaker Anti-Mode 2.0 Dual Core digital room equalizer, DSPeaker Anti-Mode 8033C/Cinema /subwoofer equalizer, miniDSP 10x10Hd not auditioned in a long time.

Thank you for your efforts. These are always informative and interesting.

Comparing this web page for Loudspeakers with my iPad subscription, I believe that there is a section header missing after YG Acoustics Carmel 2 and before Bowers & Wilkins 683 S2.

Thanks.

I'm surprised at the age of some of these components; at least two are discontinued. What's up?

We checked with every manufacturer and distributor in January about the current price and availability of everything included in the listing. It is always possible that some products have been discontinued since January.

An interesting cartridge to review, in the wake of yout review of the ART-1000, is of the AT ART-7. I've heard it and for the money I think is among the best; it might get a place in the next list of components.

Please hyperlink each component to the manufacturer's website. I should be able to click through on each component w/o having to do a Google Search first. Perhaps some components aren't represented on the web, but that will be the exception rather than the rule.

Bob Katz compared in a blind listening the Antelope Audio Zodiac Platinum Bundle: $5295 (with Voltikus power supply) and the Yggdrasil. Results...50-50. On youtube you will find a video...What are the reasons for this poor rating?
Numerous raving reviews and only Stereophile will tell us we are all wrong. mmhm

Some major names not present...CH Precision, Tidal, Mola Mola, Nagra to name a few. Is that cos' you haven't had them in for testing...?

That's correct. We have reviewed Nagra components in the past and have published a review of a CH Precision phono preamplifier since this list was compiled.

Thanks John. Much appreciate your super quick reply, and the basic list done yearly, very helpful to compare major brands. I like it a lot.

Logged this in 2016 for those lists and with no response. The lists have not changed in many ways so sending again...

There are some fine choices on the Transports, Digital Processors, Preamp and Amp listings. I am puzzled however at the total lack of mention of any Esoteric Audio product. They are current products well known for their performance and musicality. What criteria being utilized could yield a recommended components lists where at least one of their products (or more) would not make it into the results?
