I have a humidity sensor and the humidity level is less than 50% for most of the year.
Acoustically, i think carpet will work better than dricore as it will minimize reflections.

are you down in arizona? im up in ontario canada we have massive swings in
humidity here.. super dry to super wet.. my basement dose no leak to say
but in could in a huricane type rain.. but the main thing is the moisture comes right though the concrete more spring summer fall.. you cant use the ac at 40 f it will shut off.. carpet on concrete will go to mold mildew.. dont want that.. but the carpet on top of dricore lots like a good solution..

thanks

I've been finishing my basement and made the call not to do a subfloor/drycore for a couple reasons. We bought the house brand new and the builder hadn't had the grade done prior to us moving in. We ended up having several heavy downpours during the last summer before it got done and the builders people had left a giant slope towards the back of the houses basement window. I went down to check cause there' is weeping tile in the window well; half the window was under water like a fish tank lol, I had a slow stream of water coming it. The thing is that if it was to happen again for any reason I know looking at the area affected as a result that water would pool in areas of the floor and take a very long time to dry/evaporate, if ever. so after my grade was done and we obviously had no more issues; I went with underpad only for the main reason that I want to know if there's water coming in. my personal choice but I want something like that to be known and not ignored or unseen. I do think the concrete sweat issue is going to ever be an issue for me, it can get humid in Alberta during the summer but not as bad as the eastcoast. I run A/C also so that dry's the air considerably.

Off topic but the one thing I do recommend is to make sure your cold air return is located at ground level! and that you have a good airflow from it to help pull that cold air off the ground ; I also added 2 more heat vents to keep in a balanced temp making it 2 vents per 350 ish sq feet.

People do sound proof vents, but that takes some real dedication! You've got to create a snake like vent forcing the sound to bounce making it more difficult to escape. I know I've read threads on the subject over at AVS.

well i guess i spoke to soon.. dmx-1 plus the ply or osb on top
would 79% of the dri core.. save 21%..

i think all in all the dri core is better product .. you can make better adjustments for the slight roll of the basement floor to level..
and it is much stronger as well..

cheers
