Krell evolution 402 Amplifiers

4.5/5 (2 Reviews)

Product Description

Stereo amplifier 400 watts per channel with cast , large 5000va power supply. Active Cascode Topology eliminates global negative feedback, only nested local feedback is employed around individual gain blocks. The result is an extraordinarily open, liquid, effortless sound.

The signal path incorporates Krell Current Mode and CAST circuitry using proprietary multiple-output current mirrors in a complementary and balanced arrangement for extraordinary open loop linearity.

Evolution circuit topology breaks through bandwidth limitations of conventional designs resulting in near perfect performance in the audible range.

Bottom Line:   
Used with Watt Puppies 6, tube pre and transparent cables. Nice at very low volumes. Natural sound for solid state but a little lean (or too perfect?) in the midrange. Not at ease at high volume. Does not sound best on start up -- sounds better every hour - if cost no object leave it on (not me). Gets hot. Nice amp for an apartment in cold climate (again not me).

Bottom Line:   
krell has created something special here with the evolution 402. It is very natural sounding, probably the closest sound reproduction that I have heard. My Amati Anniversarios work well with the 400 watts. Krell is a wonderful match for them. I have 3 other systems with tube amps which are very good and I tested many superb tube amps (otl,ocl and with transformers) with the Amati's. The krell evo 402 sounds just as good in the midrange but much nicer sound overall , from the lows to the highs it is exquisite, superb contol and that famous krell slam. I am a fond lover of the tube sound and for years have never found any solid state that I could enjoy except now with this wonderful new krell , it is niether tubelike nor solidstate, its just real pure hifi sound.
