This month, "Fine Tunes" offers a grab-bag of useful and inexpensive tips for the impecunious tweaker searching for better sound.

As an audio journalist "servicing" the High End (ouch!), I surf the Web waves to see what's going on on the various audio newsgroups and bulletin boards. Sometimes the Net resembles the Concorde going down, the crash video'd by a passing French motorist: Ashen faces pressed against car windows driving slowly by to check out the carnage.

The dCS Purcell is named after Henry Purcell, the English composer, organist, bass, countertenor who was born in 1659 and died in, alas, 1695. It's a digital/digital converter intended for consumer use, as opposed to the less elegantly packaged pro-audio version, the dCS 972, that I reviewed in February 1999. Both devices increase the sample rate and/or word length of the output from linear PCM digital audio sources like CD or DVD up to a maximum sample rate of 192kHz and a word length of 24 bits. According to the extensive documentation, this is achieved by "using extremely powerful and accurate digital interpolation filters, which yield an output signal having negligible levels of distortion."

I love a simple tweak—one so elegant that I bang my forehead in recognition, moaning "Why didn't I think of that?!"
