Rogue Audio Atlas Magnum III Power Amplifier

@couger4u,

If you go with Rogue, get the Rogue ST-100 DARK version it’s better in the bass. Talk to Nick or Mark at Rogue Audio.

I've tried the Apollos in triode, they still have plenty of power that way (150 Watts into my 96dB speakers) but the sonics just don't do it for me. I prefer ultralinear every time. The triode mode gains you like 1% worth of a sweeter midrange, at the expense of significant bass power, slam, and dynamics. IMO the Rogue amps sound like they're supposed to in ultralinear. If you want a super sweet lush tube amp, these aren't that.

And no, you definitely should NOT use KT150 in any Rogue amps. Even in amps that can use them (like my VACs) I think they will not sound good unless the amp was designed specifically for that tube. They sounded bad in my VACs.

I noticed minimal to no difference running the ST 100 in triode with my Harbeth speakers.  seems to be mirrored by other Stereo 100 users.  

Stick to ultralinear.
