Sonos Digital Music System

Sonos Digital Music System

The wonderful thing about the free enterprise system is that so many times new ideas come from the newcomers to an industry. It forces the rest of the industry to stand and take notice. In a few cases, it even motivates a few old school companies into renewing their R & D programs. With the advance of wireless technology beginning with cordless phones, then cell phones, followed by WiFi the groundwork was laid. Some companies such as Apple expanded on this technology with products such as Airport Express. But no company had put the whole package together involving wireless, multi-room sound.

That is until Sonos came out with its Digital Music System. Using the concept of wireless broadcaster/receivers, Sonos took the next logical step, connecting the stereo system to the transmitters. In doing so, Sonos has unleashed the power of audio equipment to points throughout the home, minus a complete umbilical cord of wires. read more…

Monarchy SM 70 Pro Amplifier

Monarchy SM 70 Pro Amplifier

Over the past decade, SET is an acronym that has evolved from the fringe of the audio world, to become a phrase that even a casual audiophile can recognize. This abbreviation normally stands for Single Ended Triode, but there is an alternate meaning to this term. SET can also stand for Single Ended Transistor, which is an amplifier design that does not get quite the exposure that the tube version does. While most audio enthusiasts will recognize the name Pass Labs, there is another company that has been building single ended transistor amps since the mid 1990’s. Monarchy Audio was founded in the early nineties by C.C. Poon, who has been very active in the audio community for many years. Mr. Poon has worn many hats, including being a reviewer, the U.S. distributor for Luxman kits in the 1980’s, and now a manufacturer. read more…

JBL LSR 6328P/6312SP Studio Monitors

JBL LSR 6328P/6312SP Studio Monitors

It’s unfortunate that many of today’s engineers are unaware that JBL is a name that at one time was virtually synonymous with studio monitors. In the days before NS10’s became ubiquitous, JBL 4311’s held that same spot in studios worldwide and they pretty much ruled the roost for large soffit-style monitors. But as most things in this business, the tastes of the production community cycle in unpredictable ways, which means that the once mighty JBL name was reduced to an afterthought in most studios for almost a generation.

The last few years though, JBL has made decisive strides technology-wise in an effort to recapture the glory from years past. Starting with the initial release of the LSR series, JBL has proved that it hadn’t forgotten how to make a monitor that engineer’s want to use. Now, with the updated LSR6300 series, JBL has once again taken its place among the elite, thanks to evolving technology that features a new twist. read more…

A couple of years ago my nephew, the drummer was looking for a small “monitor style” loudspeaker, capable of near full range sound in a compact box that could be used for recording monitor purposes. He was also looking at trying a different pair of loudspeakers than his tried and true DCM TF250 loudspeakers. My sister and brother-in-law have always had reasonably good consumer grade systems, so growing up he has listened to some better than typical stuff. He’s always hung out at my house too, so he’s grown as a listener as I have, and enjoyed many of the same epiphimatic steps toward an “audiophile education” that I have. read more…

Insignia 6-1/2″ Bass-Reflex Bookshelf Speakers

Insignia 6-1/2″ Bass-Reflex Bookshelf Speakers

If you’ve been reading any of the popular audio online bulletin boards over the past few weeks, chances are you’ve heard about the new Insignia 6-1/2″ bookshelf speakers available from Best Buy for $50 a pair. If you haven’t, let me enlighten you: the internet hype machine has been going wild over these things. Threads on every major audio-related board1 overflow with discussion, photos, measurements, and glorious praise:

“This purchase is the sweetest sweet spot I’ve encountered to date in my two and a half
years in this hobby.”

“I think this speaker compares with those in the $100-$300 range.”

“For 50 bucks, nothing I have ever heard will touch it, or even come close.”

…and on and on. Well, I never want to miss out on the next big thing…trouble is I usually can’t afford it. But for $50 (with a 30-day unconditional moneyback guarantee), I could finally have a shot at running with the “in crowd”! read more…

Adcom GPT-450 Preamplifier/Tuner

Adcom GPT-450 Preamplifier/Tuner

From the 1970’s to the mid-1980’s receivers were thought to be the perfect combination for most any stereo setups. The separates market was reserved for the high-enders only. Then, in the mid-80’s Adcom rattled the affordable industry with a beautiful, clean design, power, and quality acoustics. A signature of its new vision was the integration of the preamplifier and tuner rather than the standard integrated amplifier. The reasoning was straightforward, the preamp and tuner could easily share the power source without sound degradation and at a definite cost savings. read more…

Inside-Out: Sony TA-F444ES

This month we look into the Sony TA-F444ES. The TA-F444ES was the entry level ES series integrated amp in Sony’s initial group of ES products. It is a simple, very high quality 80 WPC unit that sported some very good specifications for the time. Designed to compete with the likes of H/K, Onkyo, and Denon it had to be more than a cut above normal mass-market fair. read more…

No matter where an audio affectionado lives, there is always a sense of pride when a local manufacturer succeeds. In Portland, Oregon one such company is Aperion Audio. Started in 1998 from the simple desire of replacing a dead boom box, Winthrop Jeanfreu jumped into the 21st century direct-to-customer model using the Internet as its delivery vehicle instead of middlemen. This allows Aperion to spend more on high quality components and still meet price/ value points in the market. This model is not without hazard, as without a dealer network, Aperion must stand behind its product, which it does with a 30 day in-home return policy including return shipping. A second trick of the direct model is getting the word out without daily foot traffic of a brick and mortar store. That involves shocking reviewers with quality, and designing a very friendly web site that includes a forum. Needless to say, Aperion Audio has done well on both accounts. read more…

Which piece of equipment in the audio chain has the most difficult task? Is it the CD player? Imagine the complexity of reading all the bits off a disc and keeping them in proper order. What about the turntable? Who must battle
the enemies of vibration, friction, and inertia? Let us not forget about the speaker wire and interconnects. The cables get the thankless job of transferring the amplifier’s final output. Quite often they have to cover long distances, while having a minimal part of the audio budget spent on them. My vote goes to the loudspeaker. This component gets the daunting task of reproducing the complex nature of an orchestra, and yet it still must be capable of rendering the subtle nuances of the human voice. read more…

The DTS Pro Series Surround Encoder. A Must-Have Solution.

Hallelujah! For us Mac guys that do authoring, Apple’s latest DVD-Studio Pro 3 finally gives us the one feature so sorely lacking compared to higher-end systems–DTS file support. And while that may be well and good, the next biggest problem for the vast majority of DVDSP authors is: “Now that I can actually import them, how do I encode DTS files?” Until now, unless you had a DTS hardware encoder, you were mostly out of luck. read more…

Marantz CD5000 Player

Marantz CD5000 Player

The Marantz CD5000 is an inexpensive player commonly available throughout the world made by one of the budget leaders in digital. Is it as good as some of the The owner of this player commonly records to mini disc via the optical digital output for his listening pleasure while on the go. (He also uses his Sony MD to record live sound bites and audio tracks him and his band-mates play while practising). So– good looks, pretty good convenience and facilities but a little cheap feeling (although no more than most other machines in its price range). It also includes a headphone jack on the front panel. I did no listening via headphones, not any digital recording as I do not have the facilities to do such. read more…
