KRELL KSA 50 100 150 0r 250.

ive owned 3 krell ksa 150 amps & they were great,im not sure i'd say they have tube like mids & highs but they are great.

these amps do bass better than anything i have ever heard & do it effortlessly,the big draw back for me owning these types of amps was the massive amounts of heat they put out,these things get roasting hot when driven.

before you buy one of these amps open the hood & check out the guts,the life span of the ksa's is fairly short & if they have seen heavy use the caps will usually show it & even though krell recaps these amps at just about cost you still have to deal with shipping & 150 pound monster to & from krell & add that to the cost of recapping the amp.

hi ken,you can see visable cracks in the caps & discoloration on the tops of them,you may even notice one of them starting to leak a little,just looking wont tell the whole story but if the amp has seen extreme use you will notice.
