    Well I stumbled onto your website recently while searching for HD downloads. I’ve been downloading from HD Tracks for over a year with mixed satisfaction. First with a Mac Mini connected to a surround system in my home office driven by an NAD receiver. Couldn’t tell a bit of a difference frankly. But I knew the whole system was marginal for music. Then last year, my local high end audio store had a used SOTA turntable on consignment. I went to look at it and left with it, a new Audio Research SP17 preamp and a set of Golden Ear Triton 2 speakers. Then picked up an almost new Audio Research VS60 amp. Wired it up with Nordost. Powered it up with Shunyata. Bought a Halide DAC for the Mac and began to listen again. Huge difference between some HD downloads and the original CDs. So much so that I realized the weakness with the old lame SOTA table. Upgraded recently to a VPI Classic1 and swapped the Halide for the new Rotel DAC. Now I can finally hear most if not all the differences. Started reading your posts and understanding your basic premise regarding provenance (you are so right) but more importantly your fundamental belief that high res recording is better than analog recording. It was taking me a little while to accept this since most vinyl just sounds better than most digital. Then today, I remembered an experience I had a very long time ago. 1980 to be exact. I was living in Atlanta and visited Jim Smith’s store in Birmingham a number of times trying to decide whether or not to buy a Linn table. On one of these visits he played his HQD (I think thats the right acronym) system of stacked Quads, Hartley sub?, Decca tweeter? driven by early “real” Mark Levinson electronics. The source? A digital master tape that he had personally recorded of the Atlanta boys choir. I had never heard nor since have heard that level of realism. It was truly like being there. And the most freaky thing was that the entire orchestra was coming out of the floor. Or orchestra pit in reality. The imaging was out of this world. The reality was awe inspiring. Until reading your posts, I had forgotten the best audio experience of my life. All this to say that YOU ARE ABSOLUTELY RIGHT!

    It would’ve really helped if you had told us what the reader had said that led to this post. What was the reader’s misconception? You say it was “issues related to word length,” but what specifically?

      I’ll see what I can do. You’re right, of course. But I want to respect the privacy of the original reader and thus thought it best to withhold his exact comments.
