Sony's Digital Link Sound System brings all-in-one iOS integration to your dashboard
Is your car yearning for more iOS integration? Sony's got you covered, with its new Digital Link Sound System. The company's new audio package is available in two models: the all-in-one XDP-PK1000 and the more compact XDP-MU110. The former consists of five components, including an iPhone / iPod Touch cradle (pictured above), wireless remote control, customizable digital sound processor, 12-inch box subwoofer and 300 watt Class D mono block amp. The XDP-MU110, on the other hand, is geared toward drivers who are already content with their amp / subwoofer setup, but simply want to outfit their ride with a fresh audio system, with the help of Sony's cradle, processor and remote. If you're interested in getting one, however, you'll have to wait a little longer; the XDP-PK1000 is expected to start shipping in September, for about $800, with the XDP-MU110 slated to ship in November, for $400. Cruise past the break for more information, in the full PR.
NAD jumps into Class D with its new M2 Direct Digital Amp
Even though Class D switching amplifiers are relatively new to consumer electronics, they are receiving attention; thankfully at least some of it from the engineering (as opposed to marketing) departments. NAD has decided to enter into the fray with its Masters Series M2 Direct Digital Amplifier, a 200 250-Watt stereo offering that can accept a PCM signal directly and run it through a digital volume control before making the transition to analog current to drive your speakers. Don't worry -- it plays nicely with your other components -- there's also an ADC stage so that the unit can accept analog inputs from traditional preamplifiers. The press release touts NAD's work on the feedback stage, and there's nary a mention of ICEpower modules, so it's a good bet that the M2 is NAD's own design and not a repackaged reference kit. Sounds great, but the $6,000 price leaves us sobbing -- thankfully, this is NAD, so you can expect the tech to move down the line in the future. Hit the link for the full details.
Audioholics peels back the lids on the current crop of ICEpower-based amplifiers
Typically devoid of fancy lights, knobs, and switches, amplifiers typically don't get a lot of marketing hype; heck, most people who own a receiver aren't even aware of the amplifier section. Bang & Olfusen's Class D ICEpower switching amplifiers wrinkle that a bit -- the compact footprint, light weight, energy efficiency and impressive specs are enough to make the newer technology marketable as, well, new. Sadly, from Audioholics' examination of many samples, it also looks like the newness stopped there and several manufacturers have slapped crazy price tags on an essentially "reference design" implementation. There's plenty of good technical info about the test bench performance of these amps in the link, but with several happy ICEpower users it's hard to say that the subjective performance is unsatisfactory; the wide price range for essentially the same amp is what's troubling. If nothing else, let it serve as a cautionary tale of not falling for the latest thing just because it's the latest thing -- when you're shopping for an amp, take your ears along with your wallet.
