Krell_2250e_stereo_amp_review.jpgIn years past, Krell hasn't exactly been on the forefront of affordable technology but they have been a leader when it comes to performance and their new 2250e two-channel amplifier furthers the tradition while also managing to be relatively affordable to boot. I say relatively because the 2250e retails for $8,000, which is still a lot of money; however for Krell it's a bargain.

The 2250e looks similar to Krell's 3250e three-channel amplifier that I reviewed earlier this year - in fact they share the same chassis and construction though the 2250e boasts two-channels of amplification to the 3250e's three. The 2250e measures 17 and a quarter inches wide by seven and a half inches tall by just over 19 inches deep. While nowhere near as heavy as the Krell 402e, the 2250e's 77 pounds is still substantial. Speaking of the 402e, the 2250e takes a page from its larger sibling, offering some of what makes the 402e so magical while doing away with a few of its costlier features - features such as Krell CAST. For more on the 2250e's construction and features please check out my review of the 3250e. The 2250e dishes out 250 Watts per channel into eight Ohms and 500 Watts per channel into four. However, just because the 2250e possesses some incredible power doesn't mean it's a complete monster for it consumes less than two Watts in standby. As far as connections options, the 2250e has both balanced and unbalanced input options as well as a pair of robust five-way binding posts. A 15-amp detachable power cord rounds out the 2250e's list of features.

In terms of sound quality the 2250e sounds identical to its three-channel counterpart, the 3250e. The 2250e's overall sonic signature is one of refinement and neutrality though some may mistake it for being lean and/or forward, which it is not. In reality a lot of other amps are simply more lush. The 2250e's bass is taut with excellent control, extension and detail, not to mention depth while its high frequency performance is smooth and grain free. The midrange is also smooth, with tremendous dimension and weight giving vocals, especially female vocals such as Sarah McLachlan's, a palpable presence. Soundstage-wise the 2250e possesses a vast and open soundstage that it manages to be enveloping whilst still remaining focused. Dynamics, another Krell staple, are solid with the 2250e and its power seems limitless regardless of how loud you wish to play your favorite music or how inefficient your favorite speakers.
