For the purposes of this article, we are just going to focus on comparing A/V receiver power. We'll run through a few key things to look for as you compare the power of different models, as well as identifying some of the tricks that manufacturers use to inflate their specs.
If you are on the hunt for a new sub, the most important things to keep in mind are your room size, that is to buy a sub that can fill your space, and to also purchase one that will give you the sound quality that you prefer.
Music streaming and reproduction in multiple areas of the home is now very easily possible without the need for wall mounted complex and costly control panels.

I can assure you, dear reader, that the Erudite Audio Verbositor mkIV sports the most impressive display of buttons, knobs and blinky lights this Audiophile poser has ever had the privilege to drool over ;-)
As you read this, chances are that someone is abandoning a classic audio component-maybe something you always wanted-at a thrift store near you.¬ Here's how to rescue and enjoy it. This is Part 2 of a 3 part series. Here is Part 1 - Finding the Gems Stay tuned for: Part 3 - Cleaning and touch-up
Computers use a binary counting method that allows them to work with very large numbers - and the size of this number depends on how many bits they have.¬† In the case of most recordings, 16 bits are used to count.¬† In the case of the PS DAC, 32 bits are possible.¬† So all that happens is the analog music signal goes into a digital counting device and the musical energy is converted to numbers - bigger numbers for higher levels and smaller numbers for lower levels of music.
As an audiophile you want the best performance, and you probably aren't above spending money and trying tweaks of various sorts to help you get it. But there are real improvements that can be had without extra accessories or emptying your wallet. Amplifying circuitry can be made better without more complexity and without more feedback. The best part of this for do-it-yourselfers is that these are things that can be done on your own bench, costing mostly just the time it takes to tweak the circuit and evaluate the results. Moreover, this approach is not seen on the factory floor - for most manufacturers it's simply too time consuming to do, and the rest probably never heard of it.
It's not uncommon for a new subwoofer owner to have problems getting the subwoofer to produce audible output. More often than not, it's usually a matter of choosing the right menu items in the AV receiver, but there are some simple tests you can make to ensure that the subwoofer itself is activating properly and producing output.
As audio/video hobbyists, most of us grew up thinking that if we have an amplifier with 50 watts of rated output power into 8-ohm speakers, and that combination produces reasonably clean and loud music, then by doubling the amplifier power to 100 watts per channel, the system would then play twice as loud. Many readers likely still believe that. Not so.
No industry or brand has ever grown without extending its reach to more people. iPad is a bridge to a larger market. It is making more people aware of the choice for an automated home and at a fractional price for the interface.¬† That's important as it opens up more customers to the dealers.
As far back as 1940, with Walt Disney's production of "Fantasia", surround sound has been a concept that nearly everyone finds exciting. Consumer electronics tried to take advantage of surround for music in the early 1970s with various forms of quadraphonic sound. It never really became a mainstream success, however, due to limited recorded software and much more expensive phono cartridges or tape decks needed to play it back.
So here we are in the New Millennium, and thanks to Tom Holman and THX we've got lots of gain in our electronics. More gain than some of us need or want. At least 10 db more. Think of it this way: If you are running your volume control down around 9 o'clock, you are actually throwing away signal level so that a subsequent gain stage can make it back up. Routinely DIYers opt to make themselves a "passive preamp" - just an input selector and a volume control. What could be better? Hardly any noise or distortion added by these simple passive parts. No feedback, no worrying about what type of capacitors - just musical perfection. And yet there are guys out there who don't care for the result. "It sucks the life out of the music", is a commonly heard refrain (really - I'm being serious here!). Maybe they are reacting psychologically to the need to turn the volume control up compared to an active preamp. I suppose if I had to floor the accelerator to drive 55 mph, maybe I'd think the life was being sucked out of my driving. Then again, maybe I like 55. Nice and safe, good gas mileage‚Ä¶

The BLE2 Series replaces our popular BLE Series and continues our brushless motor advantages by featuring an all new compact, high-power and high-efficiency brushless DC motor combined with a Driver that can be digitally set and controlled via external DC voltage or by the front panel. The BLE2 Series can easily compete with larger 3-phase inverter driven motors in many more applications, with built-in simple holding torque function, saving space and increasing performance thanks to the advantages of a brushless motor design. The BLE2 Series has a maximum speed of 4000 r/min, achieving a speed ratio of 1:50 (80 to 4000 r/min). The new motor structure is small than previous models and enables high power and high efficiency while incorporating easy setting, installation and wiring. The new motor connector offers IP66 degree of protection and allows for easy and direct connection between motor and driver with two available orientation of cable outlet direction.
