correct way to turn off tube preamp

Classical1, Not to stir the pot, but I can't resist piling on your 'new' discovery of the benefits of a tube pre amp (with which I totally agree!). Wait til you hear a tube amp.......:-)

I also use a tubed pre CJ premier 16II with a ss amp CJ premier 350 and really enjoy the results. Excellent dynamics and control with much of the mid range benefits of a tube amp. Newbee has a point though tube amps are a beautiful thing once you get past the heat and maintenance issues.

I switched on my amp from standby mode before my pre which is automatically muted for the 1st 60 seconds for the tubes to warm up. On powering down, I switched off the amp to standby mode and then the pre. So far, no noise,thump or pop.....

I'm on the lower end but am also incredibly pleased with my Wright Sound WLA12A and my modded Hafler DH-200. I leave the Hafler, my tuner, and my CD player on 24/7, and none generate any significant heat, nor do they draw very much power at idle. They are way more stable being left on all the time. The Wright Sound, however, gets turned off after every listening session. Since it's tube rectified, the turn on and off is very soft, and causes no thump or other noise in the system, even if I forget to mute. In this regard, it's way easier on my system than any of my SS preamps, and sounds great to boot!

The deHavilland has @ a 30 second delay before it turns on. I've had no problems with the slight popping since using the above advice. Newbee, I think I'll go solid state when picking an amp, but I'm curious, since you have 'stirred' the pot. As I know little about tube amps, my assumption has always been that they match better with higher sensitivity speakers. Without breaking the bank can one use a tube amp successfully with monitors that have an 85db sensitivity rating?
