rogue audio m150 owners

First check your incoming power. You might need a variac, or better still A PS Audio Premier Power Plant to both regulate and clean the power.

Tube life depends on how much you play them and how hard you drive them. That said, some tubes last longer than others.

FYI: I replaced my M 150s with a number of early generation class D amps, and have not looked back. Better performance, saves on electricity, and no tube hassles.

I now use a Wyred 4 Sound MC 250/500. Lots of current reviews to wet your appetite

Chrissain, I own a Rogue 90 and found that the KT88s (Penta Labs) were reading "pretty darned tired" within a year. They still sound fine, though, and I could not distinguish them sound-wise from a fresh set.

If you retube your amps, consider something other than EHs. They are a reliable tube, but they don't sound as good as some others. Even though the Pentas sound very good, I won't recommend them as they have failed frequently for me; of the 8 or 10 I have, 4 have failed, some while very young.

My next set will be Genalex Gold Lion KT88 Reissue Tubes that most people really love.

Tweak, I recently bought a Bel Canto Class D amp (the 300 watt stereo version) which is surprisingly good. In the end, I could not bring myself to replace the Rogue with it (although I wanted to) because there seems to be a magic something the Bel Canto can quite match; very close, but not quite.

I had been driving a set of Dali Helicon 400s and just recently traded those out for a set of Dynaudio Contour S3.4 which the Rogues drive well, but surely are working harder to do so.

I had M-150s' for three years and had to re-tube them every year.
