Miner42- Thanks for your opinion. I could see the P9 benefitting from a better cartridge. That said, the Delos is supposed to be very good for the money. I believe the Dynavectors are a very nice match with Rega arms.... The RP6 would reside in my second system, with a cartridge in the $800-$1200 range.
Not sure if I could do better than an RP6 for it's $1500 price tag.
