Sherwood's incredibly affordable RX-4105 offers integrated preamplification and amplification, inputs for numerous audio source components, and advanced radio tuning and station access. The receiver delivers 100 watts RMS per channel x 2 for strong, clear sound across the audible spectrum--even at low listening levels. The company has lowered the amplifier's distortion relative to the previous model (the RX-4105), to less than 0.08 percent, while also giving the receiver a new layout borrowed from its higher-end components.

The RX-4105 uses totally discrete amplifiers for all channels (TDAS) to maintain its high power and low distortion. Use the receiver's A and B clip-type speaker outputs to power 2 different rooms, or to biwire a pair of speakers for more efficient amplification (with A outputs driving the woofers, for instance, and the B outputs driving the tweeters--make sure your speakers are compatible if this is a key feature for you).

The receiver also offers a handy 25-key remote control and switching for 2 pair of loudspeakers. Audio inputs switch between and amplify up to 4 additional components, including 2 requiring both inputs and outputs (such as a cassette deck and a VCR). The built-in AM/FM tuner features 30 station presets and auto station setup.

Other features include bass and treble tone controls, a dimmable fluorescent display, and a .25-inch headphone jack for private listening.

In addition to its voltage feedback configuration, the SR5004's amp benefits from selected audiophile-grade components chosen only after carefully designed comparative listening tests. A substantial low-noise power supply based on an oversized EI-core transformer and low-ESR capacitors assure instantaneous current delivery for undistorted peak reproduction. Marantz engineers designed a totally separate audio circuit board to isolate sonics from the spurious radiation developed by video processors. Power is a substantial 90 watts/channels so you'll enjoy dynamic reproduction of both music and soundtracks - all with the clarity that has long distinguished Marantz.

With the proliferation of mp3 players, there is an increased desire to listen to music stored on a portable device in the home. The WBT310 Home Audio Bluetooth Receiver allows consumers to send audio to a home stereo system from any Bluetooth-enabled mp3 players or THOMSON WBT420 Portable Universal Transmitter.

Heading up Harman Kardon's superb line of surround receivers is the flagship AVR 7000, which cranks out 100 quality watts to all five channels across the audible frequency spectrum. Harman Kardon, long a champion of the importance of high current over high power, offers both in this model: the AVR 7000 delivers a staggering 75 amps of High Current Capability (HCC) to drive the most demanding speaker loads without distortion.

And while sound quality is definitely a priority here--we're talking about Harman Kardon, after all--a lot of circuit-design and digital signal processing know-how went into this receiver.

Most significantly, the receiver offers Harman's exclusive Logic 7 and VMAx surround modes (intelligent 5.1- and two-channel surround matrices for any sound source--stereo or otherwise) and onboard decoding of Dolby Digital and DTS surround formats in addition to HDCD. Throw in 30 FM/AM station presets alongside S-video and component-video switching, and you're looking at your key to top-flight music and home-theater enjoyment for well under $2,000.

The AVR 7000 can also supply sound for two rooms (with the use of an external infrared remote sensor), and the receiver comes with one set of stereo RCA outputs, composite- and S-video outputs, and a separate, limited-function remote control for this purpose.

With all of its features, however, nothing gets in the way of sound performance. The tone controls--the AVR 7000 offers actual bass and treble knobs--can be taken out of the audio circuit to keep the audio signal path as short and clean as possible. In listening to CDs through either the analog or digital inputs, we found that the AVR 7000 opens a big, natural window on the music. (We recommend using your CD player's analog outputs only if it has no digital outputs or if it's a player with extremely high-quality analog circuitry.)

With the AVR 7000, the qualities we expect from separates (preamplifier and amplifier components) but don't usually get from integrated receivers abound: a wonderful sense of air and ambiance; complex layers of rich harmonics; a beautiful nuance in vocal delivery; wide dynamics and subtle microdynamics; smooth, extended high frequencies; and a bottom end that is at once powerful and well defined but never muddy.

Surround decoding of Dolby Digital- and DTS-encoded discs, performed by 24-bit, 96 kHz Crystal DSP (digital signal processing) circuits, is just as impressively clear and dynamic.

The AVR 7000's biggest drawback is that you can't adjust the speaker delays for surround formats other than Dolby Digital. Because most living rooms do not lend themselves to optimal home-theater speaker placement, it's standard for receivers to let you input and store the distance (in either feet or meters) from your various speakers to your primary listening position. This ensures that the sounds from your speakers arrive at your ears simultaneously, as if you were equidistant from all speakers. You can, however, adjust the relative volume levels of each channel, which is actually more important than adjusting the delay times.

In practice, the AVR 7000's surround sound coherence is excellent, even with DTS-encoded multichannel music CDs (though the presentation in one of our less ideal rooms was not as seamless as it might have been).

The AVR 7000 also lets you toggle between a given component's analog and digital outputs from the remote control--a function that few receivers offer. Granted, this feature will appeal mainly to audiophiles who are interested in comparing, for instance, the sound of a component's analog outputs to its digital output, or the effect that different analog audio interconnects have on the sound (using the digital output as a reference). But Harman excels in this kind of detail-oriented feature, and it's good to know it's available here.

Unlike most of the overhyped proprietary DSP modes out there, Harman Kardon's own Logic 7 (multichannel) and VMAx (two-channel) surround modes work extremely well, in most cases audibly improving over regularly decoded, discrete source material (like Dolby Digital and DTS)--no small feat. Logic 7 also instantaneously generates 5.1-channel information from two-channel material such as CDs, television, VHS tapes, and other sources, letting you take full advantage of your surround system without the annoying artifacts that often accompany such faux-surround algorithms.

Setting up the AVR 7000 is, not surprisingly, a complex and time-consuming effort, but one that pays off. To its credit, the unit boasts a terrific onscreen setup display (though it does reset your settings when you revisit a given parameter), one of the best owner's manuals we've seen, and an uncluttered, illuminated, full-function remote control capable of operating up to eight devices (choose from 17 brands of DVD players and over 80 brands of televisions).

The only other drawback worth mentioning is that the system often takes a few seconds to lock onto a new sound format, whether it's DTS or an HDCD-encoded CD. This means that you'll occasionally miss the first couple seconds of sound, but you can always preselect the format or simply start the track anew. This was not an issue in DVD video titles, where the surround format is usually triggered long before you actually need to hear sound.

When it's all configured and set to go, you'll have most of the home theater world at your remote-clicking fingertips, from full future-ready capabilities in the receiver's 5.1-channel analog inputs (perfect for DVD audio) to component-video switching for videophile DVD video performance.

If you're hankering for top-of-the-line audio performance and highest-level video switching, the AVR 7000 is a real bargain. --Michael Mikesell

Building upon a wealth of technologies, exemplified by the JVC-developed VHS videocassette recorder, the Company is moving decisively to offer appropriate solutions for the multimedia age. To remain at the forefront of the audiovisual industry into the 21st century, JVC is marshalling its resources to create the ultimate in appealing, cost-competitive products.This Dolby Digital/DTS surround sound receiver features a built-in Dolby Digital decoder, digital inputs, five power amps to drive five channels, and a subwoofer output for special effects.

With 100 watts per channel in surround mode and 120 watts per channel in stereo, JVC's RX-888VBK surround receiver offers strong, stable sound as well as topnotch features such as Dolby Digital and DTS surround decoding. While it's not constructed with the same audiophile-grade parts as many higher-priced models, this receiver is still a strong value, bolstered by JVC's unflagging attention to sound quality.

Full surround options are at your fingertips here, from Dolby Digital and Dolby Pro Logic to DTS and 5.1-channel analog inputs for future surround formats such as DVD-Audio.

JVC loads the RX-888VBK with more S-video inputs than most people know what to do with and lets you choose between coaxial and Toslink optical digital-audio connections, depending on your taste and DVD player.

The RX-888VBK uses AV Compu Link, JVC's system for enabling its components to communicate with one another. With the simple insertion of a video tape, audio CD, or cassette into a Compu Link component, a series of automated events activates the complementing JVC Compu Link products, simplifying the operation for you.

Text Compu Link is an additional step toward system automation. The system is fully compatible with text data carried on media such as minidisc and CD Text-compatible CDs and transmits this data from component to component. Text Compu Link ties together JVC receivers with JVC CD changers, minidisc recorders, DVD players, and your TV. You can choose the track you want to play from a list on the TV screen, and you can search by performer, title, or genre.

Harman Kardon's new AVR 300 is one of the most affordable high-current Dolby Digital/DTS receivers that you can get. Harman Kardon has always employed a high-current design in the amplifier section of their receivers. High current amps utilize larger transformers and transistors and are therefore better equipped to handle difficult speaker loads. The benefits to this type of technology are better reproduction of highs and lows and cleaner, crisper sound quality. Harman Kardon amplifiers exhibit full rated power response with very low distortion to beyond 80kHz. Ultrawide-Bandwidth requires selected output transistors not typically found in audio equipment. While there is no musical information present beyond the 20kHz region in current playback formats, a wide bandwidth amplifier has several audible benefits. Ultrawide-Bandwidth design contributes to superior imaging, an important stereo listening dimension, and a vital element in multichannel home theater systems. The AVR 300 is complete with Dolby Pro Logic, Dolby Digital, and DTS processors on board, as well as Hall and Theater DSP modes. DSP modes recreate different acoustic environments, making music and non-surround listening more interesting. A six-channel input is also included, so that the AVR 300 is upgradeable for future technology.

The AVR 300 is Harman Kardon's most affordable full-featured receiver--it combines Dolby Pro Logic, Dolby Digital, and DTS surround decoding and provides S-video switching, a full complement of preamp outputs, and 5.1-channel direct inputs. But there's more than features here: the AVR 300 exhibits Harman Kardon's unswerving attention to sonic accuracy and detail.

Because of its sophistication, the AVR 300 does require some effort to set up. Thankfully, Harman Kardon's owner manuals are among the most clearly written and illustrated that we've seen. Additionally, the AVR 300's intuitive onscreen display and uncluttered, programmable remote control speed the setup considerably. Our only wish is that the universal remote was fully illuminated; the only the buttons that glow are the ones you're commanding at the moment.

The AVR 300's performance, however, is outstanding. Stereo recordings sound full and natural. This receiver offers a terrific sense of air with pinpoint placement of sonic images in the stereo sound field. Dynamics are well above average, thanks to Harman's High-Current Capability. High frequencies are silky smooth and the bass scores points for both definition and wallop.

Surround sources, whether Dolby Digital or DTS, are equally satisfying, enveloping you in a wide and seamless sonic environment that makes great surround-mixed music and movies much more compelling.

And if you've any reservations about the seemingly low 50-watt-per-channel power rating, surrender them now--the AVR 300's high-quality amplifier has power to spare, even with demanding source material.

It's very simple: if you want one of the best sounding, most generously endowed receivers on the market and are willing to pay just a bit more than the average, then Harman Kardon's AVR 300 must be in the running; the returns on your investment will be anything but average.

Pros:

• Superb sound quality
• Excellent build quality
• Loaded with features
• Great value

Cons:

• Remote is not fully illuminated

Home theater may be the rage, but there's no getting around the need for affordable, high-quality music playback, and Sony's STR-DE197 stereo receiver can be a huge help in that department. The integrated amplifier pumps out 100 watts per channel across both its 2 channels and uses discrete output transistors--that is, transistors in place of cheaper and lower-quality integrated-circuit chips--to ensure high-quality music presentations.

The receiver features an FM/AM tuner with 30 station presets (20 FM, 10 AM) and a UniCommander remote control with phosphorescent glow keys for easy access, even in the dark. Separate A and B speaker outputs (stereo left/right) let you listen to the same program across two sets of speakers placed in different parts of the house.

There's no phono input, but the unit's 4 stereo analog audio (left/right RCA) inputs accommodate, for instance, a cassette deck, a VCR, your cable-box outputs, or a DVD player. (Make sure your television has sufficient inputs for the number of video sources whose audio you plan to route through the receiver.) A bass-boost circuit enhances your program's low frequencies for greater musical or cinematic input.

A switched AC outlet lets you plug another device into the receiver, conserving wall sockets and powering up the plugged devices at the same time as the receiver. When the receiver powers on and off, so also will the component plugged into the power outlet, provided you leave its power set to "on." Listening at night?
