ARC Ref 6 plexiglass cover

@lostbears ...The proper fix would have been a hole above the 6550 to act as a chimney and vent the hold.                                                                        Yes but at least with the thicker plexiglass for those that want to keep the cover on at least it wonlt melt. And i just got dont listening to it for about 2 hrs just now and the top was hot above the 6550 but not where it would feel like it was getting soft for the heat from the thinner original cover. This cover is so much thicker than the original cover that they even beveled the front and 2 sides of it.. Looks very nice too.. I would highly recommend it over the original thinner cover. Also the feel of it is like a piece of thick piece of glass compared to the chintzy thin one.

 Dweller, That is a very good idea. That would help vent heat and still look good.

 tattooedtrackman, I have no doubt the new cover looks really nice. I just wonder how hot it actually gets inside the case.

Dweller... Not more hotter than the thinner cover i would think. 

It will sound better with the cover off anyway. No matter how thick the cover it traps and amplifies vibrations, assuming you don’t have small children I’d remove it

 Probably not. But if the cover is close enough for the 6550 to melt the thinner cover, I have my doubts that the 6550 is getting enough ventilation. Heat build up can cause tubes to age more rapidly and fail prematurely.  I wish ARC had also done something to improve the ventilation. That is my only point.
