I'm sending my Khartago Mono back to Klaus for the latest board upgrade along with all the possible max. options. My cost for upgrade to Khartago Mono and second Mono with same options will set me back $1150.00 + $550 for Khartago Mono=$1700.00. That's 240,000uf with 120 Amp current delivery, essentially the Stratos Mono Blocks in a smaller chassis.
