Emotiva USP-1 Stereo Preamplifier

Emotiva's new USP-1 stereo preamplifier, at $399, sets a new standard in performance in low priced components. Besides the standard full range outputs, this preamp offers a split output where you can adjust the low-pass frequency for one (which goes to your subwoofer) and the high-pass frequency for the other (which goes to your main power amplifier). This allows you to essentially bi-amplify, and with the low frequencies removed from the high-passed output, your power amplifier will run more efficiantly, not having to waste power on low frequencies that your speakers cannot reproduce. And, they toss in a phono stage that has both MC and MM settings. This may mark the beginning of phono stages being a standard part of stereo preamplifiers, rather than having to purchase an outboard phono stage. Long live LP's! Oh, there's a headphone jack too.

conrad-johnson (lower case c and j) was formed in the mid-seventies, shortly after I became seriously interested in audio gear. I'm sure the two events were entirely unrelated. Their first product, a preamplifier, was immediately recognized as "state of the art," and so their storied history began. I encourage you to visit their website for more details. There, they provide a long list of products that have been reviewed as "Best of Class", and even "Best in the World."

If I have my Greek mythology correct, Perseus was the slayer of Medusa, the serpent-haired Gorgon monster. Using his sword to view her reflection (because we all know a mere glance directly at her would turn you into stone instantly), he was able to slay her in her sleep.
Parasound Halo P7 Preamplifier

The Parasound Halo P 7 Preamp is a problem solver. The problem is the gap between home theater systems and hi-end stereo systems. Many home theater buyers are fond of the stereo systems that they already own (and paid big bucks for), those that don't already have a stereo might find that they can afford a lot more two channel gear than 7.1 channel gear and since 90-100% of their music collection is two channel.. well, you get the idea. But unless you are a hifi nut like me, you don't have a room dedicated to the stereo and another dedicated to the home theater.

Parasound 2100 Stereo Preamplifier and 2250 Stereo Power Amplifier

As I said at the beginning of this review, now is a good time to be an audiophile. The Parasound 2100 preamplifier and 2250 power amplifier offer sound quality across the board so good I would have thought you'd have to pay at least $3,000 to get them. But, at a mere $1800, the Parasounds are a steal.
