Synergy Matching

Actually there is a ton of synergy in the studio.... start reading the liner notes on microphone and microphone preamp choices....

better yet get a couple of decent microphones, etc and educate your own ear...

Mhdt  Constantine DAC—>Audio Research sp16 Pre-amp -> BelCanto ref1000m amps -> Ohm Walsh F5 speakers.   
Also Denon DL103R cart on Linn Axis table to Electrocompaniet step up transformer as alternate source. 

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
