Doesnt resistance mean same as impedance??

The simplest definition is this:

Resistance - DC

Impedence - AC

@jjss49 ;-) lovely..i will pass that story along as we chat weekly. I understand the “ speaker closet “, mine is full of Quad, A/D/S, , Etc… Then there are the out on loan.

IMO having run the 3a-sig w many amps in a few rooms over a decade, they require an amp w grip, drive and control due to the rear mounted acoustic coupler. Your amp is a perfect match :-) My brother a 40 year audiophile has my old pair, he uses a Threshold w ARC tube pre, SOTA table. The Threshold doesn’t care about the load, sounds sublime…. Nelson and Richard aint newbies…

I always thought resistance was what is measured as ohms. Impedance included capacitance and inductance. All three combined are considered reactance, and as so impede a signal. Hence the need for the phase angle information when matching equipment, mostly amps with speakers. My thinking is fostered by the need to understand for my own purposes.

@jjss49  loved the ramble. I once owned a pair of original model IIs. Think made in 1977, I bought used in 1985.  Drove them with my B&K  ST 140. Seems to me all his speakers have the strengths you describe. Maybe more dynamic with more resolution as one moves up the line.
