Spike feet protectors


Can someone please advise based on your experience. I have purchased a pair of PSB Imagine T3 speakers. I have a carpeted floor. I can place the speakers flat on the floor, or with spikes into carpet, or with spikes into included floor protectors. Which would you recommend for sound and carpet? Thanks

Damn...waste of money. I ordered them along with herbies tenderfeet for component isolation. Ah! Can sell on audiogon....not a big loss
Herbie's has a return policy. And the Tenderfeet work very well for component isolation; amp, preamp, CD, DAC. Not so much on TT's.
Thank you. So I just want to confirm. Would spiking be the best option for SQ on carpet/plywood?
