Conversion to DSD: Does It Eliminate Digital Glare?


Hi All

  This question is for people that have gear capable of converting vanilla redbook pcm CD files in to DSD.
To my knowledge this would include the Sony HAP ES and certain DACs, such as one that I am interested in, the Mytec Manhatten.
   I currently have two highly resolving CD Players, the Oppo 105 and the Denon "Anniversary Edition" SACD/CD player.  I listen to Classical Music about 99.9% of the time.  Rest of the system is Parasound PreAmp JC-1 and Power Amp A-21 with B&W 803- Diamond speakers; Bluesound Vault-2 and Node-2;
and a MacBook Air via Thunderbolt/Firewire adapter into a 10 year old Apogee firewire dac.
  My complaint is that some CDs, particularly in full Orchestral passages, tend to harden, particularly the strings.  My SACDs (I have over 100) don't do that, and I tend to attribute this to the DSD used in SACDs.
I am therefore interested if converting vanilla rebook CDs to DSD tends to eliminate this problem.

Mahler123 - I've just completed about two years of auditioning different cables, more recently implementing acoustic treatments and lastly, the final repositioning of my speakers.

During that time I have experienced what I refer to as "glare" at varying levels and with each change I made, while playing tracks having various file types (WAV, FLAC, DSD, AAC, MP3 etc.. and sample rates from 16/44 to 24/192.

A few tracks are in a couple of different formats and a couple of tracks were recorded at different sample rates - each seemed to present a similar amount of "glare" with each of the cables tried.

Surprisingly, I also found the level of "glare" varied each time I applied room treatments. I believe the final improvements were due to the reduction in reflected waves bouncing around the room, which would indicate that they too seemed to effect the "glare" that I was experiencing.

Once I had the acoustic treatments sorted - all that was left was to reposition my speakers for a final improvement in "glare"

So perhaps what I was experiencing and believing to be "glare" is not the same thing you are hearing.

From your description - "the hardness in full orchestral pieces" is also what I experienced - along with some very shrill moments on solo violin in the upper register and some really awful moments when sopranos hit their higher register with gusto - they now all seem to have been resolved and sound much smoother and extremely detailed AND - I can play the music at significantly higher volumes :-)

So perhaps we are talking about two different things - but what I experienced during this period on my system - neither the format or the sample rates seemed to make a scrap of difference to the particular degradation in sound that I experienced.

I hope you find a resolution to the issue, because what I experienced was very unpleasant and quite frustrating.

Regards...




Many SACD/CDPs do not play Redbook to its full potential. DSD does not play a part in this, good Redbook playback is due to jitter control and often non-upsampling of Redbook files. Try auditioning a multi bit DAC, that will solve your digital glare problem.
My system is computer fronted, I eliminated glare by swapping my playback software to Jplay. DAC is NOS/Redbook only. Only CD player on hand is mass market from the 80s which sounds like ice. Perhaps it's not the DAC but CD playback?
Hey browns fan
I had read your thread about the Sony before I posted my query and was intrigued. That was one reason that I referenced the Sony, because it up samples all recordings to DSD. I already own the
Blue Sound so I am not interested in another player that archives CDs. Instead, i was hoping that if a dac that converts everything to DSD (and of course the Sony cannot be used as a dac because it has no digital inputs) would improve the sound of the Bluesound (which is actually quite good in it’s own right). Modding my Oppo might be worth considering. Sorry about Johnny Manziel.
Willi--ok, I’ll take your word that your cable experiments have worked for you, and I haven’t spent nearly the time or money that you have probably spent. I have, however, tried about 4 different cables and a couple of room treatments to no avail. I decided ultimately to use Nordost Blue Heaven because they are neutral to my ears (all that I want a cable to be) and sanely priced. They are unshielded but since I don’t have a TV in this system no big deal.
coli-my present dac is a pro piece, and I love it, but it’s getting long in the tooth. Mytec Manhatten is basically a pro piece as well, and it ain’t cheap, but it’s creator basically invented DSD and it uses firewire, which I much prefer to usb
