MDF or Plywood for best sound in Hi-Fi rack ?

franco,
mdf will be a better choice for you but for not much more money solid spring maple would put your components in a much better situation to reveal the music...
If you have the Vibrapods so much the better!
Good luck,

Very informative, thanks for the ideas and input gang !

hmmmm.....? I have all my gear on a low cost metal shelf rack and each shelf has a grate...like the racks in the oven. The cd player is on a few sheets of foam..the no skid stuff that comes in rolls and is used to line cabinents. How critical is it to get this gear on a more dense board? The turntable is on a hard board.

I would go for plywood !! Look here: [http://www.6moons.com/industryfeatures/livingvoice/definitive.html]

Maple butcher blocks are quite a bit better than both MDF and plywood. Have a look at this thread - http://forum.audiogon.com/cgi-bin/fr.pl?htech&1158841915&read&3&4&

I sourced my butcher blocks form Tony’s Woodshop in PA. He was quite a bit cheaper than all the other suppliers I tried.
