The AV7005 is Marantz's second multichannel preamplifier-processor and, at $1499.99, the least expensive pre-pro I've used or reviewed. The Integra DTC-9.8, which has been resident in my stable since 2007, when it cost $1600, and its successors, have since then steadily risen in price. The Marantz's predecessor, the AV8003 ($2599.99), was highly praised in many quarters. I never got my hands on one because, like a churlish child, I felt it lacked features I considered essential. Other reviewers didn't seem bothered by those limitations, or were unaware of them. The AV7005, however, looks and feels like a winner for music and home theater. I see no evidence of skimpingthe AV7005 sports such high-end features as balanced outputs, network controllability and streaming, and, of course, HDMI v1.4a for compatibility with 3D and all audio codecs.
As I wandered the displays and demonstrations at the 2010 CEDIA Expo last September, I found few multichannel products worth writing about. Sure, there were many interesting new speakers from Pioneer, GoldenEar, Atlantic Technology, Adam Audio, MartinLogan, and others, but really, you could just use two for stereo. I saw the requisite number of new multichannel players, processors, and receivers, but most boasted no more than some new features that made them easier to use (iPad apps were rife) and/or gave them access to new sources (audio and video streaming were obligatory).
I remember my first experience with headphones. In 1960, I bought a set of Trimm dual 'phones (less than $5) and rewired them for stereo. The experience was remarkable for several reasons. First, it brought the sounds into my headI was thrilled with the impact. Second, stereo effects, especially with Enoch Light's ping-pong LPs (eg, Provocative Percussion, Command RS800SD), were striking. Third, I could play them really loud without bothering others. Of course, they had no bass, brittle treble, distorted at high levels, and their wire headband and Bakelite earpieces were uncomfortable. My fascination with this gimmick quickly faded.
When it comes to ripping CDs and downloading music, I've been sitting on the sidelines feeling more than a bit of envy. Stereophile's reviews of various media servers have whetted my appetite, but not so much as to overcome my timidity about getting into a new realm of technology in which I would be a beginner all over again. Still, I've sneaked a few peeks.
When I started out on my multichannel mission in 2000, it was with an all-digital Meridian system that relied on lossy, compressed sources like the original Dolby Digital and DTS formats, or on synthesized surround based on Dolby Pro-Logic or Meridian's own TriField. With the appearance of first SACD and DVD-Audio and then Blu-ray, discrete lossless multichannel recordings became available, but there was no way to output those signals in digital form for interconnection to other components for playback or further manipulation. Most audiophiles, me included, already had analog preamps and power amps. It was only with the appearance of HDMI and the accompanying HDCP content protection that we could output those digital signals, and over a single cable to boot. Today, there are A/V receivers, some costing less than $500, and more than a handful of audiophile-oriented preamp-processors, that can accept such lossless high-resolution multichannel content as PCM, DSD, Dolby TruHD, and dtsHD Master Audio.
Looking back at the 2010 CEDIA Exposition, I was struck by a couple of new products which, I hope, presage a rethinking of modern electronics design. Today, the streaming of program content can be accomplished by TVs, by Blu-ray players, by dedicated servers and, for all I know, someone will put that capability into a speaker system. The result is that, unless one chooses very carefully, one will be buying the same technology redundantly. By contrast, high-end companies have striven to separate their dedicated analog/stereo products from their digital/multichannel products, forcing the very picky among us into a kludgy home-theater-bypass. Again, we end up buying more boxes and interconnections than should be necessary.
I start my second report from the 2010 CEDIA Exposition by returning to MartinLogan. As well as their $2000/pair ElectroMotion electrostatic hybrid that I described in my first report from CEDIA, the Kansas company showed the appealing new 2-way Theos. This hand-built floorstander combines a 9.2"-wide by 44"-tall XStat electrostatic transducer with a 8" aluminum-cone woofer in a bass reflex enclosure. Its large electrostatic radiator and passive woofer can be bi-wired or not with a unique tool-less binding-post design. At $5000/pair, the Theos will be the most affordable speaker in the Reserve Series of floorstanders.
Back in Atlanta's World Congress Center for the second year it is hot (around 90°F) and humid outside but it is cool at the 2010 CEDIA Exposition. On the very first full day, I found a slew of interesting new loudspeakers and that's despite having seen less than a third of the Show floor. Undoubtedly more will be discovered but it is great to say that all of the most intriguing new ones are relatively inexpensive.
The debate over which audio component is most important in determining the quality of a system's sound is one that has been with us for decades. Recently, it came up in a conversation I had during a visit to a Manhattan high-end shop, when I was told about a discussion on the topic by Ivor Tiefenbrun (of Linn) and David Wilson (of Wilson Audio Specialties). You don't have to be a seasoned audiophile to predict their respective positions, but when I was pressed to take a stand, I paused.
I've been enthusiastically tracking the development of Bel Canto's class-D amplifiers, from their original TriPath-based models to their more recent designs based on Bang & Olufsen's ICEpower modules. With each step, Bel Canto has improved their amps' sound quality and reliability.
