My buddy John Atkinson likes to say that what makes science work is <I>not</I> simply the measurement of observed phenomena, but the scientist's refusal to believe those measurements. I once asked him if he'd teach me to do audio measurements and he said no, "because you'd <I>believe</I> the measurements&mdash;a good scientist knows the measurements are trying to lie to him."

If you spotted an EICO HF-81 at the local Goodwill, you'd think nothing of this plain-Jane integrated amplifier in its nondescript gray case. But if you kept on walking, you would have passed up one of the best-kept audio secrets of all time. The HF-81 hails from hi-fi's pioneer days, before chromed chassis and slick Mac transformers. It isn't ultracool-looking, like early Marantz or McIntosh gear. It doesn't have the nostalgia factor of a Fisher. It's not a supercheap eBay steal like a Stromberg-Carlson or a Heathkit. So what's the deal?

Larger than a stocking stuffer, Musical Fidelity's X-Ray<SUP>v3</SUP> CD player is nevertheless quite compact and would be very nice to find under the Christmas tree.
