Intriguing Comparisons and a Digital Dilemma
As I was reading the beginning of this thread, my project on building a digital system resonated deeply with Ron's initial question. While I haven't delved into every conversation, the topic holds immense interest for me.
My audiophile pursuits encompass several systems, one of which is a fully digital setup centered around the Wilson Alexx speakers sourced from a 4-module Vivaldi Apex dCS system. This high-end digital chain, including dCS upsampling, Roon, a dedicated network switch, and a high-quality power supply, delivers acceptable performance but the soundstage, clarity, and overall musicality of CDs and SACDs consistently surpass what I hear from streaming services.
My dilemma becomes apparent when I turn to my beloved vintage audio system. Among several cherished setups, my "reference" system revolves around the Tannoy Autograph speakers, driven by an Audio Note UK M9 Phono preamp and various Audio Note UK power amplifiers with reference TT & analog systems. To this analog realm, I recently added the Audio Note UK DAC 5.0 Signature. This top-tier DAC primarily serves the Oppo 105 Blu-ray player for the Berlin Phil's Digital Concert Hall, high-resolution Blu-ray discs, and, occasionally, my beloved old Philips LHH-500 CD player as CD transport. I do not use in this system another streaming service like Tidal, etc...
Last week, I embarked on a revealing comparison. Using this Philips player as the CD transport, I sampled the same Berliner recording across five different formats (Beethoven´s Complete Symphonies Cycle by Simon Rattle): LP, Blu-ray Audio, Blu-ray video, standard CD, and streaming from
www.digitalconcerthall.com. While I could have downloaded the original files for even deeper analysis, I opted for this accessible comparison across readily available formats.
The results were astounding and frankly, troubling. The undisputed champion was the vinyl LP, offering an unmatched level of realism, depth, and musicality. The second place? Surprisingly, it wasn't the CD, but instead, a tie between the Blu-ray Audio/video and the Digital Concert Hall stream. These digital formats delivered clarity, dynamics, and a wider soundstage that surpassed the CD experience.
The CD emerged as the weakest contender of the five. Its sound lacked the transparency, airiness, and bass extension of the other formats, and the soundstage felt constricted. This perplexing outcome led me to question the source. Could the original Berliner CD mastering be inferior? Or is the Digital Concert Hall stream somehow "enhancing" the sound in a way that surpasses the original CD data?
Naturally, this raises the question of potential improvements if I swapped the CD transport. However, my quest for superior transport has proven fruitless so far. This humble Philips LHH-500, a seasoned veteran, has consistently outperformed high-end contenders from all Krell (including 20 & 25, Esoteric (excluding their Grandioso), Wadia, Jadis, Accuphase, and more. Only the Vivaldi dCS transport, within the complete dCS system, has ever managed to dethrone it. Some day I´d like to test CEC TL01 or Audio Note UK CDT 5.0.
Why does the CD format fall short compared to other digital options in my vintage system? Why the performance of
www.digitalconcerthall.com is superior to the original CD issued by Berliner?? This is a big dilemma for me. If someone can help me, I will appreciate it a lot.
