I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the Marten Parker Trio Diamond Edition's frequency response in the farfield, and an Earthworks QTC-40 mike for the nearfield and in-room responses. I measured the speaker's impedance with Dayton Audio's DATS v2 system.

Usually, I measure loudspeakers in our backyard, weather permitting, or in our living room with the furniture pushed to the sides. This eliminates or moves back in time the reflections of the speaker's output. However, as this loudspeaker was too heavy for me to…

That doesn't mean the future is bleak—not necessarily. Many in the industry have hope for hi-fi's future. For that potential future to be realized, however, audio dealers must adapt. Interest in better sound seems to be rising. Consider vinyl's resurgence; regardless of your views on vinyl's ultimate fidelity, it's a big step up from the earlier fashion for MP3s and cheap earbuds. (There's good news on that front, too: Those earbuds morphed into Beats…

That ideal is not easy to achieve, for many reasons. Even a straight wire of any practical length and structure has properties (resistance, capacitance, inductance) that can affect how the signal is transferred to it on one…

By unexplained providence, there have been two new releases of French chamber/parlor…

After the release of the M33 Streaming Integrated Amplifier, the next release in the Masters Series seemed obvious: It would be a stereo power amplifier, a successor to the nCore-based M22 v2, featuring the same Purifi-based output technology found in the M33.

Instead, NAD announced the seven-channel M28 amplifier ($4999), successor to the nCore-based M27. I welcomed it because the beloved, durable Bryston 9B-ST THX in my Connecticut system had recently blown an internal fuse. Its 20-year warranty was expiring soon, so I decided to…

Description: Stereo power amplifier based on Purifi Eigentakt Amplifier Technology. Inputs: 1 pair RCA (unbalanced), 1 pair XLR (balanced). Input impedance: 56k ohms + 280pF.

The NAD C 298 can be operated as a conventional stereo amplifier or as a bridged-mono amplifier. (In mono mode, the signal is fed to the left input and the output taken from the left channel's positive binding post and the right channel's negative binding post.) As Kal Rubinson auditioned the NAD both in stereo mode and as a pair of monoblocks, I performed a complete set of measurements in both modes. The C 298 has an output stage operating in class-D, so I inserted an Audio Precision auxiliary AUX-0025 passive low-pass filter between the test load and my Audio…

I finally get what those unboxing videos are all about.

As I deciphered my way through the dCS Bartók's triple boxes (footnote 1), my sense of audiophile entitlement rose as I opened each successive box. Inside the last box, the Bartók was wrapped in a black velvet drawstring pouch. That made me smile until I realized that the Bartók was so big that I had nowhere to put it. It requires a shelf at least 19" deep that can support 36.8lb. My desktop system shelf is only 16" from its front edge to the wall; previously…

Before the ink had dried on my review of the Schiit Audio Sol turntable (footnote 1), Stereophile la Jefa Jim Austin asked me to write a follow-up review on that feature-packed, $799 analog machine. This wasn't going to be the typical, try-it-with-similar-components assessment; I did that last time, evaluating the Sol with the included cartridges, the Schiit Ragnarok 2 integrated, and the Klipsch RP-600M loudspeakers.

But with all its adjustability, it's clear that the Sol isn't your average entry-level 'table.…
