Recommended Components: 2019 Edition Signal Processors

Signal Processors

A

DEQX PreMate D/A preamplifier/equalizer: $3995 ★
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 Live room correction system: Full version: €650, Stereo version: €389
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 and TJN's Anthem STR review in Vol.41 No.7)

miniDSP nanoAVR HD 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)

Reading Stereophile is always a pleasure. But I was surprised, in the April issue, by the disappearance of the phonos stages and SUT in the recommended components list. However, they appear in the list published online. What happened?

"..an impedance-phase angle sufficiently challenging that the user 'will require a good 4 ohm–rated amplifier to drive the speaker to acceptably high levels.'"

Given this in the Goldenear Triton One write up, what amps would you recommend from the A or B levels, both SS and Tube?

Time to add Ayon's Stealth, Stratos and Sigma dacs?

The Legacy Monitor HD is a "B" level speaker, but the write up was mostly negative. Having heard this speaker live, I don't hear what they hear. In some ways it is very close to the best $1800 pair I've ever heard (all music).

Is there any difference between Macintosh V. VI and LE?

Apple HomePod photo came on frot page of Stereophile but it is not in Recommended List of components. Has it been dropped by accident from the list or it is not recommended at all?

Stereophile Editors, in your humble and professional opinion, which of the following full range loudspeakers would you say are the best in this price range:
1) Rockport Technologies Avior II
2) Magico S5 Mk.II
3) Wilson Sasha DAW
4) EgglestonWorks Viginti

I am a 51 year old female that just found out I have Parkinson's, but I have been having signs of it for years, tremors, depression, body weakness. ECT. I honestly don't think my doctor was reading the signs because of my gender and age. A few years ago I had my shoulder lock up on me and I was sent to a P.T since x-rays didn't show any physical damage. My shaking was getting worse and I began falling. Only when my speech became so bad that it brought concern to my dentist was Parkinson's even considered. He phoned my doctor with his concerns about my shaking and balance problems. By this time I was forgoing shots in the back of my neck for back and neck pain to which once again I was sent to a P.T (although x-rays showed no damage) I was told I had a few spurs which were most likely causing the pain. Here I was feeling like my whole body was falling apart and doctor could not find anything wrong, maybe in was all in my head? My doctor even seemed annoyed with me and things just kept progressing and I just kept it to myself, why bother going through testing and them finding nothing? Well, it was after my second P.T called my doctor about the weakness in my legs and arms, by this time I have developed a gait in my walk and I fell more frequently. Only then did my doctor send me to a specialist and it was found that I had Parkinson's, and that I have had it for awhile. I think because I was a woman that my signs and symptoms weren't taken seriously and therefor left untreated for so long,I was taking pramipexole dihydrochloride three times daily, I Was on carbidopa levodopa but only lasted 90 minutes then wore off.I found that none of the current medications worked effective for me.I got tired of using those medication so I decided to apply natural herbs formula that was prescribed to me by my second P.T, i purchase the herbal formula from totalcureherbsfoundation. com, There has been huge progression ever since I start the treatment plan which will last for 15 weeks usage.all the symptoms and sign has begin to disappear .

How can you recommend a turntable for 2019 that is discontinued, not even in production anymore? I expect better than jut a rehash of the 2018 recommended components.
