I posted this in the Paradigm thread, but thought it might be wise to aks this over here also. I found a listing for some old Paradigm studio 100 v1's and I would like to know if I should really be thinking about getting an external amp for these. I see that that they are nominal 6 ohm but a minimal of 3 ohms in the 90hz region. Considering that amount of material in this range, would it not be wise to run these on my current AVR or should I really be looking into an external amp? It is an Onkyo TX-NR1008. Any input would be appreciated.
