"Shocking! No one with really good equipment would do this. Value just went to ZERO!!"
Dang, it’s hard to argue against logical points. But, as the elderly gentleman said after a desperate attempt to find a restroom ... "Depends."
Being a "car guy", I’d like to draw some parallels, if I may. There’s "showroom stock" with everything intact that was there the day the car was built. "Personalized" where the owner enhances the vehicle in some way. Usually performance options, but often includes comfort, handling ... AND ... safety upgrades. Then, finally, there’s "modified" where all the "rules" are off the table and you take a cutting torch or hammer to existing metal if they get in the way of ultimate objectives. The most popular group is "personalized" for many reasons. Mainly, someone loves the car, but wants to go faster/quicker, stop shorter, and stay flat in the curves while those fat(er) tires grip the road. A little "ginger bread" added -- cool wheels, custom paint, etc. makes the vehicle uniquely "yours." A KEY factor at this level is the ability to return to "showroom stock" at some point of decide to do so, provided they didn’t give away that old 2bbl intake manifold, etc.
Personally, I’m in the "personalized" category. Yes, I like to hear "good noises" when I get on it. But, primarily, I don’t want to find my self on a wet street with 4-wheel drum brakes and skinny bias ply tires. My "hill to die on" is NOT the preservation of a particular marque, but the preservation of myself, and those I care about when enjoying MY hobby -- in traffic.
While "showroom stock" represents the high mark for market value, I’ve also found that professionally built, and well-documented, "personalized" vehicles come very close to those pure, unmolested, versions. I also believe this depends on the price class of the product. For example, the ’Holy Grail" vehicles -- those valued at, say, $250k and above would appeal exclusively to purists and/or investors. Those valued at less than that may have some devaluation, say 20%, for professional builds. The 20% penalty may be money well spent for those who actually DRIVE the cars and thrash them on occasion. Or, want to pack up their significant others to provide the safest, most comfortable transport from Point "A" to Point "B."
An insurance salesmen once told me: :If you can afford to take the hit, don’t buy insurance." Adhering to this line of reasoning, related to "personalization" : "If you can afford to take the hit, enjoy the ride and don’t worry about the depreciation."
So, yes, this is an audio forum, so it’s time to take it back to music/equipment.
The goal of the "modder" is not to paint a mustache on the Mona Lisa, but to deliver the performance the original designer intended IF freed up from the burden of operating efficiencies, infield service considerations, time constraints, and material costs. We operate under "Signature Systems" badge in our little, part-time service/performance mod business. When we are finished with a project, the tech signs off on a document attesting to the fact that he followed the process exactly as prescribed. I would like to believe that our professional "mods" would have minimal impact on "market value." But, this is hard to say because our customers will need plastic surgery to get the smiles off their faces when we deliver the finished project. They have NO intention of selling them -- ever! And, by the way, our "personalized" mods can be reverted to "showroom stock" in many cases.
So, to wrap this up:
Spend the next decade taking your enjoyment of music (with your current gear) to levels that you had never imagined? Or, not have your portfolio dinged up and bit because you had the audacity to yank stuff out of the box that made it sound worse?
To "borrow" the quote from the insurance guy: "If you can afford to take the hit from the mods, DO THEM!!" If not, then wipe off your equipment with a soft cotton diaper daily to protect your investment. Is your "hill to die on" the protection of the marque (and, your investment)? Or is that "hill to die on" to provide the most engaging musical experience you can have in your home -- without reservation, or compromise?
