Channel D Pure Music software: $129
Pure Music (Mac only) can play sampling rates of up to twice the 192kHz limit of Amarra and Decibel. Like those programs, Pure Music (Mac only) offers memory play, automatic sampling-rate changes, and full compatibility with native FLAC files and in its latest version, DSD files. Going from iTunes to Pure Music, the sonic improvement was modest but worthwhile, with cleaner trebles and improved pitch certainty. Compared with the less expensive Decibel, however, Pure Music lacked some openness and clarity, decided AD. Using Pure Music in its Memory Play and "Hog Mode" settings for optimal sound quality resulted in a wider soundstage and greater sense of ease, said JA. A free, 15-day trial version can be downloaded from www.channel-d.com. Included with Channel D's Pure Vinyl Version 3.0. (Vol.33 No.8, Vol.34 Nos.7 & 9 WWW)
Channel D Pure Vinyl LP ripping software: $379 ★
Used with a microphone preamp or non-RIAA phono preamp, Channel D's Pure Vinyl digitizes vinyl LPs at 24-bit/192kHz resolution and applies the RIAA or other EQ curves in the digital domain, where there's no interchannel phase shift, capacitor distortion, additional noise, or component variability. Record mode allows the user to apply over 50 EQ curves or create custom EQ settings; Editor mode allows the user to insert track breaks or remove surface noise. CDs made with Pure Vinyl sounded "much better" than those made with the Alesis Masterlink, said MF. Compared to the original LPs, the digitized versions lacked a touch of body but sounded "very analog-like." Compatible only with Apple Macintosh computers. Version 3.0 and later includes Channel D's Pure Music front-end program for iTunes. "Pure Vinyl will change the musical lives of collectors with large collections of pre-1954 discs," said MF. JA was impressed by Version 5's RIAA de-emphasis with LPs that had been ripped with the Channel D Seta L phono preamp's Flat outputs. (Ver.5 was not yet compatible with macOS 15/Catalina in the fall of 2020.) Channel D's Rob Robinson strongly advises recording at 192kHz"Pure Vinyl was designed and optimized with that sample rate in mind (back in 2003!)" he told JAbut for monitoring the recording in real time, the playback D/A converter must be sample-synchronous with the A/D converter. (Robinson recommends the Lynx HiLo, an MF fave, for that reason.) "To say that I was impressed with the quality afforded needle drops by Pure Vinyl would be an understatement," concluded JA. "While the user interface is not as intuitive as I would like, the versatility on offer is extraordinary." (Vol.32 No.3; Ver.3.0, Vol.33 No.8; Ver.5, Vol.43 No.11 WWW)
Dirac Live 3 room-correction software: $349 stereo license, $499 multichannel license ★
Sound quality, of course, is dependent on the hardware in the system, wrote KR, about the original Dirac Live, an app that runs without external processors on Macs or PCs. But its acoustic transformation capabilities are well beyond what is built into most processors, he wrote. Live 3 allows the user to measure the system's in-room response, then generates the necessary correction filters. The Dirac Live Processor then applies the filter corrections to music as it plays. In PCs (Windows 10 and above) and Macs, it can be installed as a plug-in or as a regular application. JRiver, Audirvana Studio, Amarra, and most DAWs support it as a plug-in. Roon does not. KR continued his recommendation for the app, writing that with Dirac "I hear no loss of transparency; rather, I hear more transparency due to the removal of distracting artifacts." Live 3 also includes Dirac Live Bass Control, which KR tried in beta form. He found that "Full Bass Optimisation resulted in much better integration of the subs with each other and with the main speakersto the point where the subs disappeared but the main speakers seemed to have prodigious low-frequency extension and control." (Vol.37 No.5, Vol.44 No.10 WWW; also see JA's discussion of Dirac Live LE in his review of the NAD M10 integrated amplifier in Vol.43 No.1 WWW)
JRiver Media Center: $59.98 (single platform); $79.98 (multi-platform)
KR wrote in the January 2018 Stereophile: "If your [JRiver Media Center] setup is working to your satisfaction, there's no need for you to download every new build." Really. No need at all. But, having said that, … the 64-bit Windows version of Music Center became available in September 2017, and KR reported that it's better, stronger, and faster than the 32-bit version: "Since installing the 64-bit version of JRiver Music Center 23, I have heard not a single burp." $79.98 for a "Master" License covering Linux, Windows, and MacOS. (Vol.41 No.1 WWW)
Roon Labs v 1.8: $12.99/month, $119.88/year, $699/lifetime
Roon is a cloud-based music-playback application that can be downloaded and run on the user's desktop or handheld computer or run on dedicated file players from manufacturers including Auralic, dCS, Linn, and others. Described by JI as "a tour de force of programming, design, and metadata mining," Roon offers a graphically sophisticated user interface that, he said, looks good and feels natural. When first installed, Roon scans and incorporates the user's existing music collection. Over time, it continues to "groom" that collection, taking into account new additions to the collection and to Roon Labs' ever-growing library of metadata. With v1.8, Roon offered a major revision. "Visually, it's new, and to me, better," wrote JCA. The recommendations engine, Valence, has been improved, with useful changes to the Focus feature, which now encompasses streamed music from Tidal and Qobuznot just music in the user's library. "The music I own and the music I rent is now one big, searchable, browsable library," enthused JCA. JA is also a fan and sprung for the lifetime subscription. (Vol.44 No.5 WWW)
