I wonder if Ked also subscribes to a mainly horns/SETs/vinyl forum, maybe a big part DIY, and all those forum members had started with these topologies and had not moved onto box spkrs, SS, digital, or pricier versions of the same stuff (ie DIY Altec to AG or Cessaro, 124 or 301 to SME), if he'd also be right now be posting his Noob Linearity 2.0 thread to promote his views that they'd been stuck in the same rut they were in when they first got their first horn SETs vinyl rigs, and why they're still making naive Noob errors, and hadn't progressed anywhere more "truthful" or "realistic"?
Regarding this post, what you are saying today is not possible, because newbies now cannot get exposed to the gear you have mentioned except in rare cases. As I said in an earlier post, if any audiophile who starts off in London today, will get exposed mainly to KEF, Naim, Linn, then B&W, Wilson, Focal types. Small probability of Maggies and MLs. These will be the main shops. With audiophile music and recordings. So a newbie entry point is defined by the current state of the industry, and your first step itself starts erecting exit barriers from that strategy.
Do you seriously expect, today, SETs horns vinyl and DIY will be what a newbie will get exposed to?
