ARC Ref 6 plexiglass cover

My brand new ARC Ref 6 black was delivered yesterday 6-15-18 from ARC and to my big surprise was the twice as thick plexiglass cover that came with it. I had bought a used Ref 6 silver,natural finish that i had problems with it from the shipment (came damaged ) any way the year that the used one was built was 2016 and had the twice as thin plexiglass cover which seemed to melt on top of the power supply tube. It looks like ARC corrected this problem and now uses the twice as thick plexiglass cover , i can not see this cover melting and causing it to bubble on top of the power supply tube. Nice improvement ARC !!!  And i will tell you that right out of the box it sounds AMAZING..

I see, that’s plexi for sure. You can easily remove the existing rubber feet which will give you some more room to play with. The bigger issue may be the rear where there is even less clearance behind the plexi. In all my installs I’ve ended up needing the rear foot to be on the bottom plate not the frame.

All in it may be that a set of four feet that screw into the existing ARC holes may be a better bet. The Nordost sort fut can be purchased with threaded adaptors for example.

Anyway as you can see ARC have still not made any progress from the super basic feet their amps have always come with

@folkfreak   I guess ill just play around for now. I did buy the Vibra pods and cones for now and waiting for them in the mail,as my pockets are empty from buying the new 6 lol. But really not sure if they are better than the ARC basic feet.

Have fun! The Ref 6 should reveal whatever changes you make in feet or platforms.

@audiolabyrinth it’s an interesting question. Clearly plexi sounds better to ARC, ie performs better in resonance terms, than aluminium. Certainly there’s no cosmetic reason to change out the bottom plate for example. However plexi does have its own sonic signature. Applying a small damping device like a Marigo dot could help but given the mesh design there’s no single place to put it that would damp the whole surface I suspect.
