My pair of Khartoago monos arrived today. They appear to be no worse for the shipping and sound nice. I will post a report later on when I get them burned in. Right off the bat with less than 2 hours on them, I think they are a better match for my 4 ohm speakers than my previous tube amps. I hear more "life" and "energy" in the recording I am familiar with. I suspect it has to do with the added current delivery compared to my 45 watt tube amp. So with less than 2 hours, the Khartago monos sound great
. I will let you know how they develop.
