Synergy Matching

90 db of output how ? Pretty much any pistonic driver ( the output is in phase to the input ) are less than 90db

just run your stereo thru a couple of Ampeg cabinets...

flavor chasers vs.advancing the art and science of audio... welcome to Baskin Robbins...

More synergy:

Grado, Linn, ARC, Maggie Tympani - I first heard this in a large 30’x60’ townhouse room w wood floors, tons of plants, irregular stamped ceilings, rugs, overstuffed furnishings, books, etc ( like a real living space ), of Pasquale Grado’s apartment....  a real authentic grand piano image, tone and attack.., yes, that Grado

More synergy: Levinson, Quad , Hartley, Decca, SOTA Sapphire, Dynavector Ruby, Souther Linear tracker, in a great room

More synergy: Apogee Stage on Sound Anchors, Threshold, MX-110Z, Grado on a Basis TT

Wadia, CJ, Musical Fidelity AMG-100, Kubala wires into the ( if ya have the room ) sublime MBL-101

try to pick an opinion from somebody who might have heard world class gear And set it up  vs. just read about it..,,
