Snell Type A


I found a pair of Snell type A speakers at an estate sale the owners agreed to $250 for the pair.  They say the speakers  work.  They look in decent shape.  Is that a good price assuming they are working and a follow up question.  I see they show a 4 Ohm input; will my mid-level Denon AVR-X3300W power them?

I remember listening to amps in a showroom when they were new.

They absolutely need a stiff, low output impedance amplifier. An outboard Class D amp would do wonders for them.  Otherwise, used Parasound?
I found a pair of Meitner MTR 101 amplifiers at an estate sale for $20.  They work!  Im using them to power the woofers.  The Snell's sound better.  Thank yall for your advice.

Thank Yahweh/God/Allah/David Koresh that someone pushed back against Dr. Frankenspeaker
