There are plenty of excellent high gain amps to be had these days.
It depends on your willingness to spend for some...and your needs channels, loops, midi, switching, etc.
These are the ones I own or have owned (no longer own the VH4)
Diezel - Herbert, VH4, Hagen are all AMAZING...Herbert 3 channels, VH4 and Hagen 4 channels, midi, loops, and more
Bogner - 20th XTC...very versatile, 3 channels, lot's of switches and options
Soldano SLO - MANY classic ROCK tones lie within, 3 options (clean, crunch, lead) in 2 channels
For 1/2 the price:
Mesa Mark V is most versatile, 3 channels with dedicated EQ on each (Great amp for reasonable price)
Splawn QuickRod...late models w/4 button footswitches, from great "Hot Rodded Marshall tones" into metal tones, excellent cleans too
If you are willing to go with preamps, these can be a bit spendy but:
Bogner Fish...3 channels, classic AIC sounds
Soldano X99...midi, programmable, motorized knobs, obviously very versatile with all "THE" Soldano tones
