Very confused. I guess I'm considering the SP 853s or CMC4s or CMC8s, or DPA6022s or the CSB Cardioids. I realize the DPAs are more expensive, but are they worth three times the amount of the SPs or Core Sounds? I've already purchased the PDAudio system consisting of the Dell Axim PDA and Len's 2496 mic preamp etc. Any advice would be appreciated.
