It was 45 years ago this month that the first issue of Stereophile, just 20 pages in length, went in the mail. It had been founded by one J. Gordon Holt. Gordon had been technical editor of High Fidelity magazine in the 1950s, and was tired of being asked to pander to the demands of advertisers. "I watched, first with incredulity and then with growing disgust, how the purchase of a year's advertising contract could virtually insure a manufacturer against publication of an unfavorable report," he said in a 1974 article looking back at those dark times. And if a company didn't buy advertising, they didn't get reviewed at all. The Stereophile, as it was then called, was Gordon's answer to audiophiles' need for an honest, reliable source of information. "Okay, if no one else will publish a magazine that calls the shots as it sees them, I'll do it myself," he later wrote.

A Show like last week's Rocky Mountain Audio Fest presents me with conflicts. As a member of the press I should be spending my time covering the Show. However, I am also spending my time as a participant, in this case giving a series of presentations in which I allowed Showgoers the opportunity to listen to the hi-rez masters of many of my Stereophile recordings and compare them with CD and MP3 versions.

As well as the excellent-sounding Avalon NP2 speakers, the system I used to play back 24-bit AIF files from my laptop consisted of (from top to bottom): Metric Halo ULN-2 to convert the Firewire output of my Apple PowerBook to AES/EBU; Bel Canto DAC 3 (which I enthusiastically review in the forthcoming November issue), sitting on cylindrical wooden footers from a new company Waipuna Sound and connected to the Metric Halo box via a DH Labs AES/EBU link; Conrad-Johnson CT5 preamp and ET250S hybrid power amplifier; and Nordost Thor AC conditioner. Nordost Valhalla interconnects and speaker cables were used throughout. Equipment rack was the attractive and effective Stillpoints, which suspends the acrylic shelves from four steel cables.

I experienced a fascinating comparison in one of the RMAF rooms featuring systems from Colorado dealer ListenUp. With Sonus Faber Cremona Elipsa speakers (review forthcoming) driven by a combination of Musical Fidelity X-T100 integrated amplifier "supercharged" with MF's 550K monoblocks, and Shunyata AC conditioning and power cables, CDs played back on MF's new top-loading CD player were being compared with lossless-encoded files of the same recordings played back over WiFi via a Sonos ZP80 that fed its S/PDIF digital output to the MF player's DAC section. The data were the same, so other than the WiFi connection, there was no reason for the sound to be different. And I did indeed find it very difficult to hear any consistent difference between the two presentations. Perhaps the low frequencies were a little better-defined and extended via CD, but I don't think I could have identified that without knowing which was which. Interesting.
