Krell Evolution 3250e Are Now Shipping!



By Gary Reber


Boasting technology sourced from their award winning larger siblings, the new Krell amplifiers provide the immense power and refined performance that are the hallmarks of every Krell amplifier.  Sharing the same advanced high speed output devices, massive power supplies, and unique Krell Current Mode circuitry, the Evolution 2250e and 3250e amplifiers deliver performance that was previously reserved for products costing far more. The amplifiers retail for $8,000 and $10,000, respectively. 

Circuitry Highlights

Sophisticated and expensive to execute, surface mount circuitry is featured throughout gracing the design with short circuit path lengths, vanishing parasitic capacitance and improved bandwidth. Alone, the Evolution 2250e is ideal for use in stereo music systems. When coupled to the three channel Evolution 3250e, this duo makes ideal amplification for home theater applications.

Prodigious Power Coupled To Low Energy Draw


Blessed with a
power supply outfitted with a 2,500 VA power transformer and 136,000 µF of capacitance, the Evolution 2250e is a powerhouse.  Power output of 250 W per channel into 8 ohms and 500 W per channel into 4 ohms will drive any loudspeaker to its full dynamic capability. The Evolution 3250e design uses the same power transformer but with additional capacitance, 163,200 µF total, insuring full performance when all three channels are being called upon simultaneously. An additional transformer for control and protection circuitry also provides power for a new energy efficient standby mode. Similar to turning off a 150W light that is always on in your house; standby power draw is only 2W. This 99% reduction in electrical usage also reduces heat output substantially. The high-current and high-voltage analog supplies have additional noise filtration circuitry to reduce high-frequency switching noise.

Smaller, Elegant Chassis

Housed in elegant silver or black brushed anodized Aluminum, the Evolution 2250e and Evolution 3250e are the smallest amplifiers in the Evolution e Series. Featuring a 4U (7” High) profile, the new amplifiers bring prodigious power
to applications requiring smaller amplifiers without sacrificing sonic performance.  The stylish Aluminum faceplate features the blue power ring and low draw standby mode shared by all Evolution e Series amplifiers.

Reason #26 Why Readers Love Widescreen Review:

Before WSR, there was a 4:3 picture tube. After WSR, there is a nice 65 inch widescreen rear projection TV. However, it's only a beginning, because WSR started a dream. The reality looks crisper and clearer now, even the sound is more precise and enveloping. Widescreen Review: P5/S5, one's critic’s composite: 5. Thank you, WSR. Keep up the excellent work!
