Hey, guys.
Thanks for the great posts.
It occurred to me that we’ve been "hot rodding" audio for quite some time. We’ve been demoting OEM cables and storing them in their original shipping containers and replacing them with premium cables for quite some time. Even modern gear benefits from newer and/or better thinking, and we don’t need a soldering gun or mechanics tool set to improve their sonics with devices we plug in or insert into the factory chassis. As @jonwolfpell indicated, in the case of the Mac MC275, a lot of modern offerings are "factory hot rodded" versions of older (even Vintage) models. Factory authorized "hot rodders" have been around for long time in the car industry, too. Guys like Shelby, Yenko, Roush, Cosworth, Saleen -- even Hertz (I’m sure I’m missing some of your favorites, sorry) have gotten the full factory blessing -- including keeping the original warranty intact.
It was not my intent to agonize over comparisons between cars and audio. My examples were simply that the (very successful) automotive aftermarket can produce impressive results -- including topping the "best of the best" of modern day offerings in some respects. I tried to take the discussion out of the stratosphere of unaffordable cars and into the real world with the Monte Carlo reference where a mid-sized sedan with the right aftermarket setup (and, a skilled driver) can appear to break the laws of physics and hold it’s own in twists and turns against modern sports sedans.
I remember some words of wisdom from my old home automation days: "Just because you can, doesn’t mean you should." We need to take the "measure twice, cut once" approach to modifying our gear.
As with vintage cars, your approach to vintage audio is highly relevant on how you, individually, approach the hobby. It depends on if. and how, you drive it, race it, show it, see it as in investment and just wipe it down with a diaper on a daily basis. IF your time behind the wheel is just as important as your admiration for the marque, then upgrading the performance,saftety, and comfort are rational choices (could save your life in a precarious situation). And, there are pretty of resources to make this happen. As mentioned in an earlier post, IF you cherish and listen intently to your vintage gear the ultimate tribute would be to take the performance of the piece to a level that the original designer could only have imagined.
And, just for fun ...
