How hot is too hot?


I am running a Gryphon Diablo 300 to drive a pair of Magico A3.  My room size is around 3m*4.5M.  I usually listen at around the 80db level, mainly to jazz and classical music.

My room temperature is almost always kept at 26 degrees Celsius in the summer.  After operating after an hour or so, the heat sinks of the 300 often gets up to 50 degrees with the top cover at 38 degrees.  My dealer told me these temperatures are normal but I feel this is hot (too hot?).

I should also add that the amp is placed on the top of a flat open shelf so there is no question on ventilation.

Any experience by other Diablo 300 users to share?

TIA!

"Early experiments in 'double glazing' of windows revealed a drawback when the sun was low enough to make the test units act like large magnifying glasses, scorching paint on walls and igniting furniture."

Todays' rampant rumour..... ;)  Another being the death of Google, or at least a dearth of if....leaving us to find another verb for 'search' or 'to seek'.....
Ask me if I'm stunned....go ahead...*grits teeth...which slip on gums, nipping tongue*

Hey, @mylogic ...When is Lotus going to roll out a new 'lectric version of the 7?  Time for our Brit bros to come up with some good clean fun....👍✨🎶👏😆

Been a fan of the marque ever since I saw an Elan suck the doors off a Corvette at an intersect....back when I was young and depressionable...*L*

 

 

Replaced my windows when I bought this house a few years ago with mostly triple glazed glass (some fancy windows required double glaze for some reason), and my amps are Class A tubed and SS. I keep 'em reasonably vented and no problemo...the SS amp is a Pass XA-25 that has to warm up for an hour it hit its stride, the tube pre and power seem to sound fine immediately.

"We’re all Devo Grandpa."

 

 

Devo, the New Wave band, based their work on the theory of "de-evolution," which posits that humanity is not evolving forward, but rather regressing or devolving, particularly due to the negative influence of consumer culture and corporate control. The band’s name itself, short for "de-evolution," reflects this core concept. They used music, visual imagery, and performance to satirize and criticize what they saw as societal decay. 

 

@cdc  “De-evolution”

All the past great civilisations eventually imploded. Often due to their own making.

 

What we may have now with globalisation, global warming and mass migration (due to the first two) is the more than possible collapse of the whole human race
