Tube Monoblocks for heavy music on Khorns

Atmasphere: What did you and Brian Cheney run at the CES? I thought he liked active systems, but he probably didn't use them at CES with you, did he???

Stimbo22, Brian seems to have designed his speakers so that he can use an active crossover. I suspect that if you were to open the cabinets, you would find some minor compensation components to deal with the characteristics of the drivers. The MA-2s were used to drive the midrange and ribbon tweeters, but IMO the amplifiers were overkill! They had *way* more power than was ever needed.

hello i drive my klipschorns whith rouge audio m-150
i have test many amps ss amps tube amps krell ksa-50 but rouge audio m-150 is wery god i have a krell krell ksp 7b preamplifier and mcintosh mcd 301 cd player

I agree with Atmasphere's response. people that consider purchasing active crossovers should first consult the speaker manufacturer to find out if any wave shaping is necessary in the crossover circuitry. This is not intuitive and you must speak with the speaker manufacturer to find this out. Several manufacturers, if not the majority incorporate wave shaping circuitry in their speaker crossover designs to compensate for cabinet issues, driver response issues, etc. Also, as has been mentioned, Khorns are extremely efficient and dont' require stupidly powerful amps to drive them. The issue of solid state vs tube is left up to you after extensive auditioning.
