The local utility likes it. I tend to leave mine on quite abit, it saves me from reaching all the switches to turn on all the stuff...and on a cold day 4 VanAlstine 1200W amps in a small room keep it like a Quiznos....emmm TOASTY. Do tv stations or radio stations ever turn off any of teh stuff, same with comptuers, never turn em off, light bulbs fail when you turn em back on, if you didn't turn em off, they would probably still be working. I think a truly high end amp should have no power switch, so it doesn't ruin teh incoming line , after you install one of tehm magic AC line cords for several hundred dollars. Wouldn't you agree? How come no one has made audiophile rocker switches for the nutty people who buy magic line cords?

Most solid state amps draw very little current at idle, perhaps about as much as a 60 watt bulb. So, from the position of wasting energy, it's really not that big of a deal.

The benefit of leaving your solid state gear turned on is in having them at or near optimum thermal temperature. This does effect the sonics.

If you normally listen to your system for an hour or so a day and do so after just having turned it on, you are probably not hearing it at its best.

Leaving the gear on and a tuner or source playing will have the added benefit of keeping the cables stable. This has obvious (well, obvious to many of us) sonic benefits.

I find that an amplifier sounds so much better after it has been on a number of hours, even days that it

Cables remain stable?!...it's not hV or in an adverse enviorment, nor is any thermal emmision like filaments in tubes. as in x-ray tubes, the filaments move microscopicly, thus affecting alignment of pin hole slit and mirrors. Talking like .02 MM spaces. Thermal stability in a piece of wire at audio freqs, or any other form of "stability"? Come on...if you have SS equipment and it have a stabilty issue, you have a real piece of crap. Along with using the proper passive components, capacitors, resistors etc. Ones made for the job have no thermal issues when used in it's proper enviorment. Perhaps the ones that can hear this stabilty in an audio system, are patting themselves on their own back making beleive they have this superior hearing abilty. I'm sure your line cords have thermal propertys also?

My amps have current inrush limiters, back 30 years ago on the original designs. Tubes are more affected by on/off just like fluoresant lamps. The emmison coating on the filaments (cathode) get depleted more rapidly each time it's turned on. SS has none of this.

Always on ? Yep

Exposure XVII (pre) and XVIII (amp) are always on. In my digital headphone setup, my STAX SMR-006t is always on. On my analog headphone setup, for some reason, I turn off my Antique Sound Labs MG Head MKIII. I do think that turning tubes on and off is harder on them than leaving them on all the time. Hmmm. maybe I will turn it on when I get home and leave it that way.

Maybe I turn them off because the tubes on the ASL are exposed and they are enclosed in the STAX. Sounds like I may have a personal issue.

The simple answer is yes.The advantage,the amp is working at its optimum temperature,therefore,best sound quality.

Dup, nowhere in my post did I refer to thermal stability in cables. As usual, you have difficulty with understanding the written word and its definition. Cable stability is a topic that you can research on your own...like that is going to happen?

My solid state gear is always on. If I'm home my tube gear is on. I never know when I will need a musical fix. My system must be in a constant state of readiness.

Are you a fireman or music man? Maybe you should take over FEMA. Always Ready.

I work from home. I can and do play music whenever the mood hits me. I have found Mozart to be particularly soothing when writing code in visual basic or HTML.
