Rogue Owners Unite

Owned Metis pre for over a year now. Have found better NOS tubes can really improve sound. Am wondering if anyone has experience with Magnum upgrade results. Can't decide yet whether to dump money in Metis upgrade or just upgrade pre to say something like the mystere ca21. Like the sound of tubes through my Krell and Martin Logans. Anyone with magnum upgrade comments?

Hello, I have a Titan Atlas magnum with kt120 tubes and been noticing a hum from the speakers and when the preamp volume is increased the hum increases. Also, sometimes I hear radio signals when I turn to high volumes with no music to test what is causing the hum. The amp has never been quiet - is that Normal - but wondering if anyone has an idea what is causing and how to eliminate it?

Thanks.

@findog, sounds like badly shielded interconnects.

Thanks, Daverz, but I have used some fine interconnects such a Kimber Hero and cables from Bob's Devices.

@Findog,

The hum increasing with pre-amp volume would seem to indicate that the problem is not the amp. It could be a ground loop.
