Stereo Is Father to the Surround: Al Kooper Talks 5.1

Al Kooper has been a mastermind behind the board of many a storied session over his half-century career, but his prowess as a multichannel mixmaster has been largely unheard — until now. Audiophile circles have long been well aware that Kooper had turned in “interesting” 5.1 mixes to Sony for a pair of albums he personally had stakes in — Blood, Sweat & Tears’ trippy big-band-influenced debut, Child Is Father to the Man (originally released in February 1968) and Mike Bloomfield, Al Kooper, and Steve Stills’ still influential jam amalgamation, Super Session (July 1968). Both mixes gathered multichannel dust on the corporate shelves until almost a full decade later, when Audio Fidelity released them from captivity by way of a pair of Hybrid Mulitchannel SACDs. Here, Kooper, 71, and I discuss his surround mixing philosophy for both of those classic releases, why he’s not a fan of mono or streaming, and his alternate, Bloomfield-centric mix of Bob Dylan’s “Like a Rolling Stone” (on which Kooper played the infamous improvised organ riffs). There are no longer any 5.1 secrets to conceal.

IR or Not, These Apple Apps and Devices Put You in Control of the Remote

It’s rare to be able to mention a feature that’s found on an Android device that wasn’t featured first on an iPhone, probably with a sleeker presentation. Somehow, however, IR remote control ability seems to have been left out of iPhones, even though it was rumored to be included on the iPhone 6. Samsung, LG and HTC all have managed to include IR blasters on their phones, yet Apple devotees have been out of luck if the want to control their home theaters, until now.

Homeworld Remastered

After the implosion of THQ and the rights to the game bouncing from publisher to publisher, Gearbox studios picked it up and ran with it.

We’ll, sort of. Instead of making a new game, Gearbox took the original Homeworld, and updated the graphics.

This is 100% fine by me. Here’s the deal…

Krell Chorus 7200 Amplifier Test Bench

I'm genuinely curious so please don't take this as a trolling attempt:

To the best of my knowledge an amplifier's function is to take a weak (source) signal, amplify it, and pass it on. Now, if that's the case, how on earth can one amplifier improve (or even just impact) imaging better than any other amplifier in any other way than applying more or less power?

Willie...thanks for the question. Every amplifier has its own signature sound, depending on the topology used in the electronic path. Some do it much better than others, that's for sure, but a "bad" amplifier will introduce noise and distortion into the signal that will get "amplified" with a higher output. Throw in a week power supply/transformer and you have a poor performer. If the design is done right, like this one here, you get a very clean rendition of the original signal. Does that make sense?

How can you give this unit 5 stars when it can't make its own rated spec of 200W per channel?
These honestly look more like AVR class amp benchmarks than those of a Krell.

Bootman,I don't see the benchmarks until you do. All of my evaluations are done without knowing how it measures. All I can tell you is despite it falling just short of its rated spec, the amp sounds outstanding. As for calling it an AVR class amp...I beg to differ. Try and find a local shop that can audition it for you and you'll hear what I mean.

Ok I'll admit the AVR comment is a bit harsh.
I guess I'm not used to seeing Krells measure so short on rated power.
When I hear Krell I envision KRS monoblocks driving Scintillas.

Thanks for your insight David. Since you have reviewed both this and the ATI AT-6005, how would you compare the two?

Any comments from Krell why this unit can't make its rated output? Is this an isolated case for this unit? Or is it true for the whole chorus line?

Krell Chorus 7200 Amplifier


Performance
Features
Ergonomics
Value
PRICE $9,500

AT A GLANCE
Plus
A new take on amplifier classes with iBias
Superb dynamics and soundstage
Ethernet capability for system monitoring
Minus
LED illumination too bright
Extremely heavy

THE VERDICT
Krell’s iBias technology has allowed them to deliver the benefits of a Class A multichannel amplifier in a way that will have audiophiles grinning from ear to ear.

Do you remember what it was like sitting for your high school or college lessons? Well, get ready for a trip down memory lane, because to give the Krell Chorus 7200 the praise it’s due and explain just how much this “little”-amplifier-that-could is going to change the audio industry, we’ll need to start with a short class in “classes.”

Sin City: A Dame to Kill For

Picture
3D-ness
Sound
Extras
Sin City: You will never find a more wretched hive of scum and villainy. In A Dame to Kill For, the second big-screen adaptation of the works of writer/artist/director Frank Miller, we find that stripper Nancy (Jessica Alba) has been driven cuckoo-bananas by the events surrounding the death of her hero and one true love a few years ago. She now finds herself shadowed by the ghost of Bruce Willis (where have I seen that before?)
