Recommended Components: Fall 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)

B

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)

Does anyone own any of these Recommended pieces?

If so,

Can you tell us about it?

I did head to head comparisons versus Berkley, EMM, Ayre....for me in my system the Bricasti beat the Ayre and Berkley and tied with the EMM for far less money. Their support has been OUTSTANDING as well. I had an issue with one channel and they took it back and performed upgrades on it to make up for the inconvenience. As other new upgrades come out they are great about retrofitting to the latest. Great sounding device. Great support.

VPI Classic Signature with SDS power box, SoundSmith MIMC (OK, not the "star" edition), EAR 834P phono pre. In all a lovely, lovely set-up - fast, musical, extended, glorious mid-range. I am officially off the analog upgrade train except for some possible upgrades to the EAR in the future (some vintage Telefunken tubes have already taken it to a whole new level).
Once you figure it out and get a few of the right tools, the VPI 3D arm is not that difficult to set up and the on-the-fly adjustable SRA is terrific.
Interestingly, the Classic Signature drew my attention due to years of mostly good VPI coverage in Stereophile, the EAR came by dealer recommendation and audition, and the SoundSmith was a shot in the dark based on my intrigue with the moving iron concept, and the speed of the "moving coil" version. Turned out to be a wonderful combination...

I know you guys hate digital but surely the Sony Play Station 1 has not been reviewed in a long time. It has been on the recommended list for what seems like forever. Other components are deleted after a few years. Get over it. Your precious analog won.

It would be much easier to read the reviews of recommended components if there were links to them in the recommended listings, rather than having to scroll through past reviews to find them.

I thought the Pono Player was discontinued last Spring. It seems to be still available through some retailers, but shouldn't the company's decision to change directions at least be mentioned?

there's a typo in the price, or at least an extra digit. it's not a $10k cart.

I noticed that the price of NAD D3020 is still shown as $ 499. For the last two years or slightly longer, the actual price for the D3020 was $ 399.99.
At the same time, we were duly notified about the price drop for the very next entry, PS Audio Sprout to $ 499. That is creating a false impression that they cost the same.

"For the DragonFly Black, output voltage has now dropped from 1.8 to 1.2V, but in the DragonFly Red—which also has the distinction of an ESS Sabre 9016 DAC chip with 64-bit digital volume control—output voltage is bumped up to a healthy 2.1V, which AQ suggests better suits it to drive difficult headphone loads."

I think the DAC chip in the Dragon Red is ESS Sabre 9018 (9016 is in the Black).

Also, IMHO, the iFi Nano DSD LE is far far better than the Dragon Red
in terms of sound quality via the Amplifier (with Foobar2000 as the
source). I have both of them. So good that I bought another iFi Nano LE

to use with my other system. The problem of the Nano LE is that the
USB port isn't really secure when I accidentally move or touch the USB
chord it may stop playing. This happens with both units with either USB2.0 or USB3.0 cables.

Compared the list to the last one + deletions and there is no trace to the Vivid Audio g3.
