Vandersteens on active speakers and room correction

Pro Tip for those running the automated tools - do a run at normal listening hours and again at 2am... compare !

its all about s to n in the room

Actually Eric it’s amazing how reruns with the computer generate different results....

at the end of the day, no computer is going to fix a cone that is out of phase to the input signal 1/3 of the time over large % of the radiator- again it cracks me up that people obsess about distortion or hyper flat frequency response and think 33% is a good number....

the ugly elephant is pistonic eliminates trash which today counts as efficiency !!!!

I think IF your everyday  Listening tool is a pair of Vandy 7 speakers and amps in a great room with a preamp of your own design with a Brinkmann / Triplaner / Lyra Atlas front end, iF you could get an active digital box to sound better, I would expect Richard to be all over it. There are designers who do choose to go the active route. Certainly the Roger Modjeski designed Beveridge filter is IMO one of the best sounding.
Fundamentally, Vandersteen is an analog company, I am a black sheep with my digital front end 7 system.Funny how both my Aesthetix DAC and ARC preamps have defeats for the chip driven displays - both sound better OFF. I suspect that because the Jim White designed DAC puts all the digital stuff inside a Faradcage, the defeat effect is smaller. So it would have been the easy route to use a chip to manage cooling on the model 7 amp... a designer who lives by principles :-)
fun
good music

I have my unpacking, setup, breakin and long term listening notes from 1k hours of use... maybe this thread will get me to clean those up :-)

IF you go to my Poverty Bay Sound system page, there is a sneak peak underbthe hood of the Model 7 High Pass Amplifier...

Actually it makes perfect sense and is as Richard says “ an unfair advantage “ for a speaker designer to build an optimized amp for the load AND back EMF. The architecture and hyper innovation is Richards, the detail design is the partnership in genius he has with Dick Klidnfelter of PSE fame.

high pass , the power factor corrected feed forward sub amp takes load off.
just five parts in signal path
no emitter resistors
liquid radiator cooling for stable temp and no thermal bias drift
tube front end, SS driving load
no global feedback
analogbtemp control circuit no microprocessor hash...
built in hanging truss HRS isolation
silver Audioquest speaker wire with 128 v DBS included...
