HD Down Load compared to Analog.



Lately, I've been comparing HD Down loads to "analog". The obvious first advantage is no pops and ticks, but that's just for old records. Another advantage for me personally is that I don't have class "A" analog, I have class "B", which is very good. I still use Stereophile magazine's ratings of equipment as a way of conveying how good a piece of equipment is. While folks here put that method of conveying how good a piece of equipment is, they still concur with it, and they don't even know it.

Class "A" analog is the best, and it's always very expensive. You have to have 100% class "A" in the chain to yield class "A" sound, which is why I have Class "B".

In my comparison evaluation, I used Santana "Abraxas" as the test LP. Since I've worn out 5 copies of this album, to say I'm familiar with it is an understatement. "Singing Winds And Crying Beasts" is the first cut, it has "tinkly" sounding chimes that test definition on all equipment. After listening to a new LP, I gave it an "A" rating. This meant the HD Download would have to be some kind of fantastic to top the LP.

As soon as the music began, it became apparent the HD Download was superior; there was a "jet black" background. This is something I had never heard before. I'm fully aware of the fact that's an "oxymoron". "How can you hear what you don't hear, and you have never heard before". Only an audiophile can understand that, consequently, I won't try to explain it. After only two cuts, I gave the HD Download an "A+" rating.

While I have Class "B" analog, if you have Class "A" analog, it might be better than the Download, I don't know. These are the results from my comparison, I would like to hear yours.

I'm waiting because have heard only one HD DAC source. I haven't had the time to research more or find another store to hear other units for comparison. It also gets a bit bewildering figuring out the best way to get from the computer to the preamp. e.g. USB, jitter reduction boxes, firewire, BNC, etc.
I'll share my experience with regards to HD audio. Some months back I got to listen to a very high end system. ARC 40th Anniversary Ref, Ref 610, CD8, Ref DAC and an Oracle turntable outputted to the big Maggies. It was a magical night. (Let me just say as a side note that this system sounded fantastic and very musical, in fact, I think the Oracle had a bit better PRAT than my Sota; but I was still able to come home and enjoy my humble system.) I got to hear some CD's, some records and some HD music files. Analog on this system sounded very musical and enjoyable. Then we played some "select" HD files. I say select because my buddy said there is a lot of variation in sound quality even among HD files. To me, the HD music was as good as analog but without any background noise. The soundstage was just as large and holographic as analog. Then we we played some CDs the music and soundstage just seemed flat in comparison; and this was on the ARC CD8! I'm sold on the HD files route but I am bewildered with all of the choices that must be made and not having a way to audition various systems leaves me out in the cold. I want to go HD, just that I am waiting and trying to sort out the best path.
You know, 33 1/3 LPs are not the standard of Analog- Reel to reel master recordings are. LPs are full of compromises. LP vinyl was the sound medium for the masses. If the internet were around 3 or 4 decades ago this same discussion might be going on about reel to reel vs. LPs. LPs have the advantage of decades of technology development which has brought it a long way- to be sure. A lot of hurdles have been overcome to lift such wonderful music off of a vinyl disc; but it still has many limitations. eg. The signal is compressed in the grooves, hence the RIAA curve and the interpretation of that curve by various preamps, cartridge design, tonearm design and of course, speed control of the platter. CDs are built around the same paradigm as vinyl using a laser instead of a needle and a motor based time system. So many of the challenges of vinyl were carried over to CDs. I have found mechanical isolation of my CD player has a big impact on the sound quality just like with my turntable. CDs are really a hybrid- half analog and half digital. So my point is that HD Digital downloading has the potential to one day give the masses the same level of quality as the master recording. For that, I am excited about it's potential. Sure, it will highlight bad recordings and bad mastering just like actors and newscasters had to adjust to the higher detail and resolution of HDTV; but eventually I think HD Digital promises to bring us to a new level of hifi.
