Question Arcam delta 290 bad sound

I own an Arcam delta 290. The mids sound muffled . The bass is bad , warm powerfull but so out of " focus " , not tight in any way. The highs seem roolled off. Iīve heard other arcam delta 290 and they all sound like this (nothing wrong with mine) , the only upgrade i did was replacing power supply capacitors for 10000mf 63v , didnīt change the sound only made it more powerfull.
Maybe this is really and old amp and better leave it as it is or anyone knows how to upgrade/fix this ?
