  1. I am happy to be in complete agreement with Chris' article (shall we say rant?). I took up the free 3 months offer to play around with it: clunky interface, no direct hardware control (sampling rate issues), and dismal search. In short, the same disappointments. There is one aspect I do appreciate. By commoditizing the "hi-res" streaming audio market, the potential impact and market share of MQA is challenged! And that's a good thing, but for different reasons. I also belong to the camp of disagreers of misleading or false claims about the superiority and benefits of
  2. From my experience, the negative impact of longer cable runs is higher with USB than with analog RCA. My example is the use of a cheap 3 Meter USB cable to connect a Macbook Pro to a Gustard X20u DAC. At the max sampling rate of 384kHz PCM I am getting occaisional drops, which is annoying and concerning. My concerns is with the induced noise from the extra length and subsequent jitter. I currently have an iFi USBPurifier or Jitterbug in the signal path, which doesn't seem to eliminate the drop problem. With a long RCA cable run you might deal with other degrading facto
  3. Coming to this read very late. I have been accused being a walking music lexicon, having started with The Beat Club on B&W German TV in the 60ties. From all the countless music recordings I have listened to in every imaginable format since then, there are still only a handful good recordings that stand out. The articles mentions a few. But compression is just one of many problems that make music less enjoyable, or in some cases unlistenable despite brilliant music artistry. I hate to say it, and it is really not my preferred music style at all, Jazz in the Pawnshop is a prime example where
  4. I am not a fan of hateful, and in the case, unqualified opinion. What exactly is the specific experience with Audio-gd that leads Peggy to write such rubbish? I have one Audio-gd product in my stack, the compact Precision-3 power amp for a secondary system. Since it's unrelated to the content here, I will only say this: it is a high-quality product for a bargain price with excellent and responsive support and amazing sound. If you want to read a reliable review of their R2R DAC, go here: http://www.6moons.com/audioreviews2/audio-gd/1.html
  5. @med_designer The DAC in reference is an Audiophonics I-TDA1387 custom design for Raspberry Pi. The board itself is ridiculously inexpensive (€60 +s/h). I am using it in combination with a KALI I2S re-clocker board from Allo, which is supposed to reduce jitter errors by replacing the RPI clock source. There is a plethora of blogs discussing the various technical aspects of DIY/Raspberry based designs (a good one is Archimago's Musings and of course @opus101), but in the end, I let my ears do the judgements. It is very intriguing to follow the DAC/digital design developments over the years, no
  6. I am a proud owner of a low-budget R2R NOS DAC setup involving a TDA1387 setup with Raspberry base. I find it amazing how the sound quality appears to be more pleasing than many sigma/delta based DAC's. I compare it with ES9018 based designs ($1k range). The tech specs of the TDA1387 don't suggest superiority, but in the end, the audible results matter more to my ears. Huge soundstage, high resolution but vinyl-like warmth, high dynamic. The circuit design appears very simple with 2x4 1387 chips in series. Music listening range is from acoustic jazz, classic/prog/alternative rock, EDM, electro
