Dave Schulte sent me back a completely transformed integrated and all for the better. Resolution, focus, dynamics, depth and dimensionality were all significantly enhanced. Tone is more accurate and instrumental textures and image density are increased. Everything just makes more sense and is presented with increased low level detail...no distortion or grain evident. Spatially it sounds more tube like but without the smokiness and softening sometimes present.
Congrats with you "new" Krell
Could you detail what this is? Is this an official Krell upgrade you can get? I have the 400xi as well.
Would be interesting to know how any upgrade compares to the S-300i.
I wonder how sound and cost compare between selling the 400xi and buying the 300, to upgrading the 400xi.
