Rating: 4 out of 5 stars - * How to get cheap AAAA for the Revolution! ...
Just a small tip to get AAAAs for cheap:

Take apart a 9v battery, and boom, you have 6 cheap but great AAAAs that work awhile in this!

I've had much better luck Energizers than Duracells, however.

Rating: 5 out of 5 stars - * Great Little Item! ...
If you need to boost your sound from any item that has a 3.5 plug in...this will do the trick. I plugged this into my ipod and cell phone and was able to use a splitter so that my wife and I could use our headphones when we travel to listen to our music. Works great with or without a splitter. Highly recommend. M Pousson



Rating: 4 out of 5 stars - * Great addition to your audio, with a few small caveats..... ...
This is a great little gizmo for anyone looking to boost up the music of their portable devices. It does exactly as advertised. Makes the sound better without having to put up the volume all the way.

This is what I used it with:

Media Player: Archos 605 80GB wifi
Headphones: Sharper Image Quiet Place FJ453, which I then will be using it with Grado SR-80s

As I mentioned, there are a few caveats to this:

- The battery cover is HARD to take off with just your hands. I recommend using a flathead screwdriver or something similar.

- The batteries. This uses AAAA batteries. Yes, that isn't a typo. There are such things as AAAA batteries. They aren't as readily available as AAs and AAAs, but I've heard you can purchase them at Staples and other office stores. I bought packs of them from ebay for cheap.

- These only work with Higher-end phones. Some people have complained of a white noise/feedback sound. If you use lower-grade phones, you will hear this noise. This is when you have to use the original boostaroo. Upbeat audio has created a list of which headphones are suited for each of their devices [...]

In conclusion, I recommend this only if you have high-end headphones and don't mind AAAA batteries



Rating: 5 out of 5 stars - * Does what it says - AMAZING !!! ...
I'm using high end Etymotic ER4P earphones (27ohms), and a Treo mp3 player running PocketTunes. This amp is amazing. It not only boosts the volume but notably increases the bass as well. In the past the EQ on my player was kind of useless, but now with this amp I can really use the EQ and dial in the sound just how I like it. The amp seems to slightly muffle the sound a bit, but my music is overall warmer sounding now. Basically it reminds me of the warm sound of listening to a tape, but with none of the downsides of a tape recording.



Rating: 5 out of 5 stars - * UNBELIEVABLE ...
FIRST I PURCHASED THE ULTIMATE EARS TRIPLE-FI IN EAR HEADPHONES FOR MY NOT SO EXPENSIVE MP3 PLAYER. THEY SOUNDED JUST AS ADVERTISED, "LIKE BEING IN A SOUND STUDIO". THEN I PURCHASED THE BOOSTAROO REVOLUTION AMP, THE DIFFERENCE THAT THE AMP MADE WAS INCREDIBLE. I USE MY MP3 MAINLY WHEN I RIDE MY HARLEY DAVIDSON, NOT THE QUIETEST MOTORCYCLE AROUND AS MOST PEOPLE KNOW. WITH ONLY ONE EAR PIECE IN, AS THE CALIFORNIA LAW REQUIRES, THE SOUND VOLUME AND QUALITY IS AMAZING. WHEN I GET TO USE BOTH EARPHONES IT IS NOTHING LESS THAN EYE POPPING SOUND. HIGHS AND LOWS ALIKE. I CAN ONLY IMAGINE IF ANYONE IS UNHAPPY WITH THIS PRODUCT IT CAN BE NOTHING LESS THAN A FAULTY UNIT OR VERY POOR QUALITY ELSEWHERE IN THE SOUND SYSTEM.

Joshua Logan's 1967 film of the hit Broadway musical about the love triangle between King Arthur (Richard Harris), Guenevere (Vanessa Redgrave), and Sir Lancelot (Franco Nero) is strong on star emphasis and weak on such fundamentals as story and sets. Except for a handful of solidly dramatic scenes--such as Guenevere grieving, late in the film, for the ruination she and Lancelot have caused--there's not a lot to get excited about. (The story's theme of a lost, great society, however, certainly struck a chord in the 1960s.) The Lerner-Loewe songs ("If Ever I Would Leave You," "Camelot") pretty much sell themselves, even if they are, at best, only proficiently performed in this movie. --Tom Keogh

"The book was better" has been the complaint of many a reader since the invention of movies. Frank Darabont's second adaptation of a Stephen King prison drama (The Shawshank Redemption was the first) is a very faithful adaptation of King's serial novel. In the middle of the Depression, Paul Edgecomb (Tom Hanks) runs death row at Cold Mountain Penitentiary. Into this dreary world walks a mammoth prisoner, John Coffey (Michael Duncan) who, very slowly, reveals a special gift that will change the men working and dying (in the electric chair, masterfully and grippingly staged) on the mile . As with King's book, Darabont takes plenty of time to show us Edgecomb's world before delving into John Coffey's mystery. With Darabont's superior storytelling abilities, his touch for perfect casting, and a leisurely 188-minute running time, his movie brings to life nearly every character and scene from the novel. Darabont even improves the novel's two endings, creating a more emotionally satisfying experience. The running time may try patience, but those who want a story, as opposed to quick-fix entertainment, will be rewarded by this finely tailored tale. --Doug Thomas

On the DVD


Listen to our interview with Frank Darabont.
Anyone who has seen this Oscar-nominated film knows Frank Darabont likes to t-a-k-e h-i-s t-i-m-e. He certainly does the same in filling all three hours of his commentary track which he recorded over several sessions. Darabont has studied other DVDs and purposely does not repeat tidbits covered in the excellent new 90-minute documentary on author Stephen King and the making of the film. Other solid segments are two deleted scenes, a never-used teaser trailer, and Michael Duncan Clarke's screen test. The highlight is two remarkable tests of Tom Hanks in old-age makeup. Both are very credible, but it was decided to use another actor. The outcome is a DVD that puts the "special" back into the special edition. --Doug Thomas

When Roman tribune Marcellus Gallio (Richard Burton) is sent to Jerusalem, one of his assignments is the crucifixion of Jesus Christ. Marcellus, a cynical and hardened man, wins the robe Jesus wore to the crucifixion while gambling with other Roman soldiers underneath the dying savior. He later becomes convinced that his hallucinations and violent outbursts are the result of a curse received from the robe, which is now in the possession of his escaped slave, Demetrius (Victor Mature), somewhere in the Middle East. He sets out to find Demetrius in order to destroy the robe and the curse and finds faith instead, converting to Christianity. This was the first movie to be filmed in CinemaScope, and won Oscars in 1953 for costume design, art direction, and set decoration. The visual aspects of the film are stunning, and it may be worth viewing for that alone; however, the script and acting leave much to be desired, and you won't find inspiration in these areas if that's what interests you. If, however, you are more interested in this film for its religious matter, the story of the conversion of the hardened Marcellus is inspiring. --James McGrath
