amplifiers and preamplifiers

Say what you want about soundbars, but the category counts as one of the more active areas of speaker design. Sure, many products pumped out over the last few years are low-end ones designed to be sold as accessories for flat-panel TVs. But plenty of serious speaker companies have also gotten into the game, and the performance of the resulting products, while not yet at a level to make audiophiles toss out their tower speakers en masse, has proven more than sufficient for casual home theater use, as well as for background music listening.

We've long been fans of CEntrance's portable USB DAC/headphone amp, the DACport; in an expanding market of bus-powered USB DACs, the venerable unit (along with its streamlined sibling, the DACport LX) remains a favorite of, and reference for, many reviewers of portable audio gear. Now they've gone ahead and put out a complete two channel system, of all things — the Audiophile Desktop System.

There’s some debate among vinylphiles about whether USB phono preamps need to exist, but I for one am glad they do. When I bring home my latest haul of vinyl from Amoeba Records, I love being able to plug a laptop straight into my NAD PP 3 to make quick MP3s of albums I like so I can listen to them on my smartphone. (Sacrilege!) It’s easier than making an analog connection, and it bypasses the lousy analog-to-digital converter built into my laptop.

With the Zphono-USB, Parasound brings new versatility and features to the USB phono pre concept.

I am of the school that believes that more power is always better than less power. That school also professes that amplifiers, while operating within their linear abilities (a big “if”), are not generally distinct in their sonics.
