I use to have a VTL 300 Deluxe Mono Blocks from the early 90's, pretty basic amps. I replaced them with VTL 450MKII Mono Blocks. The sonic improvement was minor, just a bit more power but the Fault Protection and Auto Biasing is a huge improvement.
With the added technology, I get much longer tube life which lower operating cost. These amps have 16 KT88's and at 60 bucks a pop it can get pricy.
