I am new to this forum. Been a Hi Fi enthusiast most of my life. Currently have a decent turmtable and cartridge (Grado Blue), using a Marantz 2230 as a pre-amp and a Carver 100 watt power amp. Have some Older Radio Shack Optimus spealers that i have alway thought were pretty good sounding. Polk is currently offering some good prices on their older line of Monitor 70 speakers. Any thoughts on this product??
