150w Stereo power amplifier

Featuring technology derived from the aerospace industry, the Étude is an incredibly compact stereo amplifier with stunning power, speed and clarity.

The multi-award winning Chord Electronics Choral family of products has never sounded so good. Welcome Étude to the table, a 150w Class AB stereo power amplifier featuring the first fundamentally new topology since Chord Electronics’ inception in 1989, using highly advanced technologies seen within the aerospace industry.

The Choral Étude has been designed to both compliment and exploit the full potential of the multi-award winning DAVE DAC, which has preamp functionality, and the brand new topology has even faster power delivery than exiting designs, offering unrivalled dynamics, life-like delivery of transient information, plus effortless control over loudspeaker drive units.

The design for Étude is based upon multi-feedback and dual feed-forward error-correction amplifier technology that intelligently adjusts and compensates the individual linearity of the 250-watt lateral structure high-power proprietary MOSFETs. Internally there are three individual high frequency switch mode power supply units, one for each active power rail and a final for the auxiliary rails. When paired with advanced internal shielding, active cooled plenum chamber design, and custom Chord Electronics MOSFETs, you have Étude, an world class extremely fast crystal clear amplifier.

Although the amplifier is conservatively rated at 150W into 4Ω, if you run Étude in bridged mono mode you can increase this to 300W into 4Ω.

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.

Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it. Orange is easy to see in the grass at day They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

loud but in a good way
Size: 4.5"
Love these crazy loud squeeky balls. I bought two a bit too big but the dogs still love them. Yes, they will drive you insane but the dogs love them so much it's worth it watching the pups enjoy the balls. They are strong and safe as long as they aren't too small for your dogs mouth.
