MUSINGS: On Michael Fremer's "How Best to Hear Patricia Barber's 'Clique!'" - selective hearing and more MQA nonsense. [Extended Edition!]

A little bit of dramatics for effect. ;-)

Like many audiophiles, I've been well aware of Patricia Barber's recordings over the years. Her discography of "reference"-sounding quality albums have already had decades of influence among hi-fi enthusiasts with increased exposure beginning in the 1990's (her first album was Split in 1989). Personally, I was introduced to her music with Café Blue released in 1994.

I think Barber is an interesting contrast to the other well-known female jazz vocalist we all know well - Diana Krall. Barber's material tends to be more original (less of the standards), more edgy, compared to Krall's accessibility and mainstream appeal.

Already, on this blog, I've mentioned the most recent album Clique! (2021, DR14 hi-res, DR13 MQA-CD) but we're not going to be mainly talking about the music on the album in this post. Rather, I want to explore the opinions and beliefs of Michael Fremer in his article "How Best to Hear Patricia Barber's Clique!" recently posted on Tracking Angle.

REVIEW: S.M.S.L. DO100 DAC (dual ESS ES9038Q2M) [Part I - Overview, Filters & Jitter]. (And the likely continued contraction of MQA...)

Over the last number of years, we have seen a proliferation of DACs from Chinese manufacturers offering models of increasingly better resolution - higher fidelity - and greater feature set. These days, I am of the opinion that we have achieved way above and beyond the ability for human hearing to differentiate these machines unless the manufacturers purposely added some kind of "coloration" to the analogue output whether it be frequency response or changes to the noise and distortion levels (the "tube sound" being a prototypical example we may come across).

As you can see in the image above, we have the S.M.S.L. DO100 DAC (~US$250) in today for review. I bought this unit through retail channels and intend to either use it myself or give it away if I have no need for it.

For many devices these days, opening the manual will show us technical information like the frequency response of the filters in this example. I think this is a nice evolution among manufacturers recognizing that showing product performance is important to educated customers with graphs and technical details rather than mere prose which often provides little satisfaction for the consumer's intellect.

Today, let's start a multi-part look at this DAC; no need to hurry because I think the performance at this price point warrants serious consideration and the many ways and features one can gather performance metrics on (I don't promise to test everything of course!). Obviously it's not an expensive device, has a remote controller, has both unbalanced RCA and balanced XLR outputs, Bluetooth 5.0 input, capable of up to 32/768 PCM and DSD512 (1-bit, 22.6MHz) using USB 2.0, along with S/PDIF TosLink and Coaxial inputs for up to 24/192 and DoP DSD64. No money wasted on MQA licensing. Depending on what we find, this might be right for you...

"MQA-CD x UHQCD" Listening Test by Agitater.

[Editor's Note: As you may have read in the last few months, there is a new variety of "MQA-CDs" released into the wild. Here in the West, we have seen the new release by Steve Reich Pulse/Quartet contain MQA encoding (playback FFT commented on here). In Japan, a series of MQA-CDs have made their way into public hands from Warner, called "MQA x UHQCD" (UHQCD stands for Ultimate HiQuality CD) which is basically a combination of MQA encoding + "better material" on what is still basically a standard "compatible" CD with 16/44.1 PCM data at premium prices. I guess this kind of thing still interests Japanese audiophiles!?

Techmoan did a review of these which IMO missed the mark as the reviewer clearly does not understand the limitations of MQA itself and believes it really is a "high resolution format" which is IMO false as previously discussed. He also used a glitching portion of Brothers In Arms as a gauge that the MQA-CD sounds "better" through the Pro-Ject Pre Box S2 rather than normal playback (clearly the MQA decoding and filtering changed the output amplitude on the Box - the MQA playback sounded louder).

Techmoan's video did not really compare actual CDs already on sale for years with these new MQA/UHQCDs using higher quality equipment - he just used a computer setup and headphones, obviously having trouble getting things working. To "fix" this situation, here's Agitater and his buddies on Steve Hoffman's Forum! With his permission, I've posted in full his detailed listening sessions conducted with audiophile friends on very high quality systems. Slight editing with headings added for the blog format. A beautiful write-up that just had to be shared and not get lost within a message forum!]

Asked and answered . . . Here are my music listening group's listening notes and conclusions about the following four UHQ/MQA-CD releases. The albums are, in order below Moanin' by Art Blakey & The Jazz Messengers, Blind Faith the eponymous album by the early supergroup Blind Faith, Getz/Gilberto by the studio trio of Stan Getz, Joao Gilberto and Antonio Carlos Jobim, and Aja by Steely Dan.

Here's the DAC. It's a MyTek Brooklyn DAC+ with fully switchable MQA filter. Note the little, blue MQA indicator light. It was used in all of the listening sessions in a variety of systems, and acquitted itself brilliantly. Note that one of many peeves related to MQA DAC implementations is that the MQA filter can't be turned off and is applied to all streams including non-MQA (standard?) CDs. MyTek made its licensing deal with MQA, obviously, but in the process has retained its own superb filters. That's my Benchmark DAC3 HGC (unused in these listening sessions) below the Brooklyn DAC+.
