I just this past Friday picked up my Krell EVO 402 which was upgraded at Krell to the 402e spec amp. New faceplate, new box, etc. They told me that it would need a week or so of break-in to sound the way it should sound.
The change in sound quality was apparent from the moment it was plugged in. I forgot immediately all the cursing I had done moving that heavy amp back into the system. It is an amazing upgrade in sound quality. Much more than I ever expected.
The sound? Instrumental parts are more clear, the sound presentation is fuller and warmer. The echo on tracks (both concert hall echo and studio recording echo) is shorter, more accurate, less ring. There is a more open presentation of the overall sound, but especially more open and relaxed in the top end. Dynamics are more apparent but also more relaxed; if that sounds confusing then let me say that everything sounds more like music than before.
It is a huge upgrade in sound quality for the money. Krell did the upgrade in a week and it is worth every penny--and I have only been listening for 24 hours. I am eager to see what develops after a week.
