I don't seem to have much time to myself these days, so don't have much time to do a full review of these headphones. But I was impressed by the build (no flimsy build here) and the audio quality, so I just had to make a short posting here for people who may not have heard of them. Check them out, take them for a test and you will be happy you did. The I-Mego Retro Classics Heavy Beats Headphones resemble the old Shure microphones Elvis used back in the 50′s. Very Stylish.
The Retro headphones are I-Mego’s range-topping line (sold for about $70) currently consisting of three models: Classic (chrome/white) mainly meant for human, vocal, new age and classical music and Heavy Beats (brown/gun metal) meant for R&B, Hip hop and rock, and a new red version for full range articulation which has just been released.
Transmitted Audio Quality: If you are a serious SSB operator like I am then you will pay close attention to the transmitted audo quality of your signal. Two black boxes that you basically use for HiFi SSB are the 8 Band EQ and the EQplus produced by Julius Jones, W2IHY. I have found that these two gadgets produce a transmitted audio that is as close as broadcast audio quality as I can get on SSB and Julius did a great job. I get consistently excellent reports on my transmitted audio quality and have also found that with signals that I receive and find with exceptional audio quality that the station on the other side is running the same pair of black boxes.
Yaesu's engineers had dedicated themselves to the enhancement of Signal-To-Noise ratio in designing the FT-920. Since recovered audio is the most important consideration at both ends of the communication circuit, the FT-920 is particularly optimized for noise reduction, wide dynamic range consistent with excellent sensitivity, audio tailored to the operators own voice pattern, and ease of operation. The result is an efficient transceiver design without a peer in its price class.
High-Tech Receiver Front End The FT-920's receiver front end, adapted from the FT-1000D and FT-1000MP legacies, utilizes an up-conversion technique, with a 68.9 MHz first IF being produced by the four-FET doubly-balanced first mixer. Following the first mixer, a four-pole "roofing" filter protects the following stages.
This front-end architecture results in excellent image- and intermodulation-rejection characteristics for the receiver system.
New-Design MOS FET Power Amplifier Utilizing rugged MRF255 FETs in the final amplifier, the FT-920 produces 100 Watts of clean output power from 1.8 MHz through 54 MHz! Built into an aluminum die-cast unibody chassis, the FT-920's thermal dissipation capability is unnmatched in its class.
High Speed DSP The audio Digital Signal Processing (DSP) system of the FT-920 runs at a blazing 333 MIPS (Million Instructions Per Second), providing highly-effective filtering and noise reduction with a minimum amount of distortion or "artifacts" that can degrade reception. Noise reduction, bandpass filtering, and auto-notch filters are provided, in addition to a microphone equalizer to boost talk power and enhance audio quality.
Oustanding Digital Mode Features Easy interfacing to digital modes is yours with the fT-920, and its flexibility for digital operation is beyond compare.Both AFSK and FSK connetinos may be accomplished, and the AFSK line is isolated from the microphone jhack, so you never have to worry about a "live mike" while you're on PSK31. PTT, fixed-level audio output, and squelch status lines are also available.
And for connection to a tape recorder, a convenient "AF OUT" RCA-type connector simplifies audio interconnection, independently from the TNC connections used for digital transceive operation.
CW Operating Flexibility For CW experts, the FT-920 includes a CW Spot control, for precise alignment of your frequency to that of the station you're working. You also get a CW Tuning Meter, CW-Reverse sideband selection, a CW Pitch control, and a CW Message Memory electronic keyer, with storage and recall access from the front panel.
Advanced Multi-Function Display The FT-920's Omni-Glow™ display includes a specially-engineered wide-angle lens, to ensure clarity of viewing over a very wide range of angles. The high speed digital metering includes a "peak-hold" feature, to allow easy monitoring of peak signal, power, or SWR values. You also get monitoring of the input DC voltage, speech processor compression level, DSP relative bandwidth, Clarifier offset, and a host of other information including tuning meters for both CW and FM modes.
Those who know me and my transmitted SSB signals know that I care allot about the transmit quality of my signal.I am not one of those local DX'ers who run tons of QRO power and don't care about the quality of their transmitted audio (you know the ones with excessive power, terrible audio, over compression and splattering!).
The constant compliments I receive over the air on the quality of my transmitted audio are a testimony to the efforts put into the front end audio processing.
With the 3 main rigs that I run on HF, FT-2000, TS-870S and the FT-920, I have paid special attention to ensure that the SSB signal is transmitted either in enhanced or extended SSB. But thanks must also be given to many friends on air and off air who are professional broadcasters as well as professional audio engineers who have given me lots of advice in order for me to achieve my ESSB goals.
For the FT-920 it is run in enhanced SSB mode and I use a combination of the KAM RT-1 - Ribbon Tone Dynamic Microphone into a Behringer FEX800 Enhancement/Effects Processor + FEQ800 Equalizer and a Behringer "Shark" DSP-110 Gate/Compressor/Preamplifier:
Here are some videos of what HiFi or ESSB can sound like:

High-precision 11-point AF sensor The wide-frame SAFOX VIII autofocus system features 11 sensor points (with nine cross-type sensors positioned in the middle) to automatically capture even off-centered subjects in sharp, crisp focus. Select from 11 or 5 points or manually select any one of the sensors as the focusing point to accommodate specialized applications.
Compact, lightweight body Despite the incorporation of the large 23.6mm x 15.8mm image sensor, the K-x is one of the most compact, lightweight digital SLR cameras available. It offers easy one-handed operation.
Live View function with choice of three focusing modes The Live View function allows you to view the image on the LCD monitor during shooting. Select from a choice of three different focusing modes during Live View shooting: Contrast AF, which optimizes the focus based on the subject's contrast; Face Detection AF, which automatically detects up to 16 faces, selects the main subject's face from multiple faces, then captures it in sharp focus; and Phase Difference AF, which uses the AF sensor positioned in the camera body to optimize focus on the subject. Coupled with the half press focus activation, this gives unprecedented ease of use in Live View.
HD Movie Capture The movie recording function extends the benefits of high-quality SLR photography to the world of movie shooting. It captures beautiful, true-to-life movie clips in 16:9 high-definition TV proportions (1280 x 720 pixels) at a frame rate of 24 frames per second.
PENTAX-original SR (Shake Reduction) mechanism The PENTAX-developed SR (Shake Reduction) mechanism effectively compensates the adverse effect of camera shake by as much as four shutter steps, assuring sharp, blur-free images even under demanding shooting conditions. This innovative mechanism is compatible with almost all existing PENTAX interchangeable SLR lenses – both old and new.* * Lenses compatible with this mechanism are the PENTAX K-, KA-, KAF-, KAF2- and KAF3-mount lenses; screw-mounted lenses (with an adapter); and 645- and 67-system lenses (with an adapter). Some functions may not be available with certain lenses.
High-speed continuous shooting The K-x's high-speed continuous shooting mode records as many as 17 images (in JPEG recording format) at a maximum speed of approximately 4.7 images per second at 1/125 second shutter speed – the fastest of all entry-class models. Its top shutter speed of 1/6000 second allows you to preserve sharp, crisp images of fast-moving subjects.
Innovative image processing functions to produce distinctive photographic effects (i) Digital filter function This function allows you to process recorded images in a variety of creative ways within the camera and produce highly creative visual expressions. With a choice of 16 different filters, you can even apply different filters, one after another, to a single image to create more personalized visual effects. (ii) Cross process mode The K-x features the new cross process mode, in which the camera automatically and randomly shifts photographic parameters for each exposure to create eye-catching images with unique colours – just like pictures treated with the cross process*** in film photography. This playful mode adds the elements of surprise and unpredictability to digital photography as you cannot expect the outcome until the captured image is actually displayed on the camera's LCD monitor. *** A film development technique that takes advantage of unconventional film developers to create a distinctive finishing touch with intriguing colours.

SteelSeries has released a pretty cool set of full size headphones called Siberia v2 and they have the heads of Gamers and audiophiles turning! Siberia v2 headphones feature 50mm speaker drivers, a retractable head band, the frequency range is 10 to 28,000 Hz and they are of 32 ohm impedance.
SteelSeries Siberia v2 incorporates an ‘invisible’ retractable 50-16,000 Hz microphone system (you can find it at the bottom of the left ear-cup) that you can use for VoIP chatting. The headphone has a good 2 meters extension cable and two 3.5mm jacks for audio and mic.
SteelSeries Siberia v2 headphone is released in two models, one with USB sound card while the other is just a plain model. Both have been available since November 2009.
At time of writing I am listening to these cans and find that they are very comfortable with the headband being self adjustable via self retracting wire cables. The leather ear pads are also very soft and pliable and there is no pinching or clamping feeling when wearing these cans. The sound is extremely dynamic and fast with details in full abundance but not over whelming or fatiguing. Bass is not constricted, it is well controlled and expansion is deep for these new cans right off the rack. Tonal balance, transient response and coherence for all ranges is extremely good.
The model I have is the plain version and not the USB version.
The nice part is the mike which can be completely concealed when not required. I am very pleasantly surprised by the overall quality and design of theses cans. The design is also extremely stylish and tasteful.
A set of cans that I do recommend for those die hard gamers/ head-fi'ers amongst you.
SteelSeries Siberia v2 Headset Selected for the 52nd Annual GRAMMY® Awards Performers and Presenters Gift Bag
2010-01-26 16:57:03
- SteelSeries, a leading manufacturer of game peripherals and accessories, today announced that the SteelSeries Siberia V2 Headset has been selected to participate in the 52nd Annual GRAMMY® Awards official gift bag. As the headset of choice for both gamers and music lovers, the SteelSeries Siberia V2 Headset brings GRAMMY presenters and performer's superior sound and microphone technology in a stylish and comfortable design.
How does an aluminum disc magnetize? The inks used on the the disc label may contain materials that can pick up a magnetic charges as they are moved in and out of their case and the CD transport, and whilst spun at high speeds. The impact of this magnetization is very acute on older discs, which can be sonically rejuvenated with a Disc Demagnetizer. But even brand new CD's, DVD's, Blu-Ray, and other formats will benefit.
Each demagnetizing cycle takes about 8 seconds. After the first cycle, turn the disc over, and run the second cycle.
Originally developed by Japanese companies who marketed such products at a very high price, the Chinese made Runsheng SH-2A does the same job at 1/4 to 1/5 of the cost of Japanese products. I tried the cycles on a few of my favorite CD's and I immediately noticed they sounded cleaner, quieter, bass was tighter, mid and upper registers had sparkle and have luster.
The Chinese Runsheng SH-2A is retailing for US$62.00 and is a steal compared to the price of similar Japanese products. It is marketed in NA under a different name and also not at such a low price.
Today I replaced somewhat scratched old VFO spinner knob on the Icom IC-R71E with a new VFO Spinner knob rescued from a defective Kenwood TS-440 that was written off. The rubber trim around the side is better then the original Icom knob for tuning. Here are a couple of photos:
