Do you keep your amps and preamps on all the time

SS amp on 24/7
Preamp (tube-based) on during day/off (standby) at night
CD player on 24/7
Tuner on 24/7
Open ventillation for all components.

The 24/7 on components use about 0.21 kWh (about 40 cents/day).

I do not leave my stuff on all the time.My amp is high BiAS'd ,but I really do not think it would do harm in shutting it down. I have had it for 12yrs and it has given me great sonics.I do think it does need 20mins to heat up ,but so doies the CDP which I use as a transport now. The CDP gets hotter than my Amp I think.

Having ventilation I do think is important and common sense. Odyssey I think says you should have 2ft. of clearance.I do not believe that stacking is a good thing because of Interference,but I only have 6" of clearance over my amp in order to keep the IC's short between my Passive Pre-Amp.My amp does not use Global Feedback and the shelve above the amp does not get hot so I think it's OK.Any problem with that?

What effect does having amps that have global feedback in their designs state is should be used? I would think that having stuff stacked over amps that use Global feedback would really have a negative effect. What effect does it have if you have something interfering with the field I wonder?

Does anyone have any info on this about Global Feedback designed amp or am I missing something. I do not think I will ever own an amp that uses Global Feedback anyways.All the amps I am intrested in use a DC Servo Loop.

TIA

I keep 'em on all the time except bad weather or trips, but I run SS with relatively low idle consumption. Almost all SS will have no problem being on 24/7 if you don't mind paying the power bill. Tubes are a different matter altogether; running 24/7 will reach lifespan on most tubes within a year or two.

I switch the amps and pre to standby when I go to sleep and work. If I leave them on to much heat is generated and I have to run the AC more.

My electric bill actually went down $6 a month once I started leaving everything on idle 24/7. I'm outta town right now, so the system is down!

I'm running a Bryston 4B-ST now & it only gets hot to the touch, in the 90's when I was a Krell junkie you had to sit naked in your listening room in the summer.

I actually recall talking to a Krell owner who lived in AZ who installed his components in a hall closet w/ long xlr's, then added a window air-conditioner which installed in the closets exterior wall!

Heat does have a whole lot to do with leaving it on!
When I got back into Home Theather in 1999 I picked up a Sony Str-444ES for Dts. The Sony sounded great when it was left on, however once I left it on for 72 hours straight & the A/V rack shelf above smoldered!

The Sony got hotter then any Krell Kst/Ksa of the same wattage! Forget eggs & steaks!!! You could have taken a Video Corespondence Blacksmithing course & use the Sony to bend Horse Shoes!!!

The Sony was dumped for a Denon Avr-4800 w/ a built in fan which served me well for 3 years, on all the time & never an issue.

Does it pay to leave it on 24/7, yes in my case I guess the whole initial firing up pulls a whole lot of juice.

Secondly I enjoy not having to wait to listen, as there is a major sonic difference having SS equipment on 24/7!!!

As long as you components Heat isn't a Fire Hazzard!
