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.

I would suggest you consider an outboard DAC and pay particular attention to Johnny Darko's DAC index and comments on CD playback . 16 bit music can be irritating on a poor recording but if well recorded a good DAC will allow you to enjoy it. Some DAC designs accentuate the shortcomings of 16 bit recordings, others are at least neutral. Up-converting to me = equalization... you gain improvement in one area and loose in another

In the FWIW column, listen to the Cranberries if you want a test disc for 16 bit shrillness... if your DAC can tame them without loosing detail, you have a keeper
 One of the recordings that bothers me the most with glare is an early 80s CD transfer of and Ormandy/Philadelphia recording of Sibelius Second Symphony (early 60s recording).  Yesterday I was playing the same recording from a Japanese Ormandy collection, presumably remastered transfer (I can't read the liner notes since they are all in Japanese)
and lo and behold, most of the glare isn't present.  
Does conversion to DSD eliminate glare?
Conversion of PCM to 128/256/512 DSD is desirable with delivering a more accurate analogue signal to your Pre Amp/Receiver/Amp and more closely emulates the analogue signal delivered from a TT or Reel to Reel setup, while endeavoring to ensure accurate translation of the original source recording to an analogue signal.

So the question you can ask is... can a TT or Reel to Reel (analogue) setup sound GLARY? ... of course, the answer is YES :)

You always need to pay attention to your setup, especially your speaker placement/setup and room setup :)

It would appear that translation/upsampling of PCM to 256/512 DSD is (can be) a good idea, especially if no Dac is used and the noise can be effectively dealt with (cleanly removed) :)
mahler123 I am interested in further discussion insofar as I have a system very similar to
yours...B&W802D2's etc....and listen more or less exclusively to classical music.  I had a Denon 1713UD universal player and replaced it with the Oppo 105d, which improved on clarity at the expense of harshness.  I then added a Luxman DA-06, based like the Denon on BB 1795 chips, and believe I achieved clarity greater than that offered by the Oppo, with full-bodied resonance particularly complementary to piano music, and with overall sweetness and smoothness.  Annie Fischer's celebrated recordings of the Beethoven piano sonatas, which manifest some treble thinness ? related to her partial 'reworking' of her venerated Boesendorfer, sound wonderful with the Luxman.  String quartets are another matter...again I prefer the Luxman sound.  So now I wonder what improvement in clarity, without loss of a full-bodied sound, the new generation of DAC chips might offer.  Perhaps you have some thoughts regarding this.  Of course these choices overlap with digital formats.......
