you would have appreciated what Dave Slagle has done with his built-in bi-amping of his Quad 57's.
(link below)
Like the author of this piece, I've long loved and lusted for a pair of Quad 57s, even had them in my apartment for a couple weeks in the late 70's as a friend who owned them was moving and needed a safe place to stash them until he could safely transfer them into his new spot.
But these are of another dimension. Likely what should have been had market forces prevented it.
Story goes that a guy called up Slagle and ask him to custom wind a replacement step-up transformer for a blown one in a quad panel. Think about it. A tube amp's output transformer is a step-DOWN transformer which, if hooked up to a QUAD 57 sends the signal to the QUAD's step-UP transformer to supply the voltage required to drive the panels. How does that make sense?
So, Dave solves this by building two tube amps (one for treble one for mid base) and two 'custom wound' output transformers matched to the impedance of the PP amps and the panels, and attaches time to the back of the panels. Crossover is done at line level before the signals are sent to the respective output stages.
Everything played on this system sounded like it was live and being performed 'in the room. I wasn't allowed in the sweet spot for long and was soon relegated to the corner where I remained until they had to shut down for the day and, as Dave is a friend, security was not called.
OK, credit where credit is due. If I had a few $million$ to spend on audio, Win Tinnon's scratch build, slate, rim drive table with a Schroeder arm and custom step-ups for the MC cartridge, etc. would be sending the music to those custom Quad ESL-57s.
And yes, I have that Julie London LP pictured in the link below and it sounds pretty good on my system, but nothing like the one Dave and Win put together at RMAF back in 2015.
First they came for the dumb-asses
And I did not speak out
Because I was not a dumb-ass
