One very visible change in the C1.2 is the introduction of MQA support, which was not present in…

At CH Precision, the model-number increment indicates upgradeability. Physically, the C1.2 is very similar to the C1. The ".2" designation indicates that if you own a C1, you can upgrade it to .2 status—for $4000. The D1.5, though, is so different from its predecessor, the D1, that it's not physically possible to upgrade the older to the newer: The D1.5 uses a different transport, with a different door height. Not to worry though: CH Precision offers a guaranteed buy-back in cases like that.

Sidebar 3: Measurements
I measured the CH Precision C1.2 with my Audio Precision SYS2722 system, repeating some measurements with the higher-performance APx500. The external power supply and clock weren't available for the testing. The C1.2's coaxial and optical S/PDIF inputs and AES3 input accepted data sampled at all rates up to 192kHz. Apple's AudioMIDI utility revealed that the C1.2 accepted 16- and 24-bit integer data via USB sampled at all rates from 44.1kHz to 384kHz. Apple's USB Prober app identified the C1.2 as "CH Precision USB Audio 2.0" from "CH Precision" and indicated that…
I never collected baseball cards, played Cops & Robbers, or was a Boy Scout. From the moment I heard the opening guitar riff of Blondie's "One Way or Another," at age 6, it was clear that music would be central to everything I was going to do. It was my first important big thing, and my last.
Soon I was exposed to heavy metal, during its golden era. I devoured it with the voraciousness of one of the demons on those album covers. Money I made from chores went right into the cash registers of my town's record stores. But unlike my friends, I wasn't satisfied with the big, obvious bands…
In last month's Re-Tales column, I discussed the impact the current economy is having on the hi-fi industry. Some hi-fi companies said sales have "normalized" after widespread, dramatic increases during the COVID years—which is to say, sales are down relative to their peak but still strong. Others have noticed customers biding time before making expensive purchases or opting to buy less-expensive equipment than originally planned. Yet, even in this risky economic climate, a few people are taking the risk and opening new brick-and-mortar retail stores.
All the dealers I spoke to sell some…
To be a poet is to be tormented. And singer/songwriter Townes Van Zandt's demons were relentless: mental illness, addiction, willful recklessness. He constantly complicated his life and the lives of those around him. Even fans who felt lucky just to have him play their town were unwittingly drawn in, often exhilarated but occasionally aghast. Yet judged by his recordings, he was indisputably a songwriting genius—often sad and confused but gifted nonetheless. The scion of a storied and wealthy Texas clan, he was that rare artist who was compelled to create art.
As John Prine put it, "…
Before this month, I'd never experienced Rotel amplification in one of my own systems, but I have memories of how their amplifiers sounded back in the early 1990s. In those days, at audio shows, I would audition every Rotel amp I could find; I was especially interested in their $369, 60Wpc RB-960BX. I was curious about that model because it was the number-one competitor to the 60Wpc darling of the audiophile proletariat: Adcom's GFA 535 II. My friend Corey Greenberg compared these two popular amps in Stereophile and concluded, "The Rotel is for the budget-minded music lover who wants a good…
The 4-CD set of Ligeti's complete Deutsche Grammophon, Decca, and Philips recordings entitled Clear or Cloudy (Deutsche Grammophon 00289 447 6443) held my attention for two long nights. The sound from the Rotel DT-6000 sourcing the RA-6000 was moderately shy on reverb and atmosphere but fully alive and dramatic. Like most avant-garde music, Ligeti's art directs listeners' attention to dramatic contrasts of volume, force, and tone—and, more dominantly, the passage of time. The Rotel excelled at the volume, force, and time-passage parts but fell a breath short on recovering a full harmonic…
