You wanna talk ridiculous? Time to get prehistoric in terms of ridiculosity (vocabulary check on aisle 4 - "riduculosity" or "ridiculousness"?) and sound and how it gets from here to your ears.
I don't think that amplifiers are necessarily transparent, and even if they were, it wouldn't make a difference. There are too many things to get in the way of the music arriving at the listener's ears sounding the same way that the musician is hearing it. Do you use tubes or transistors? What sort of cable runs between the instrument and the amp? What's the configuration of the speaker cabinets? What sort of power (tube or transistor) are you using, and do you use a pick or play with your fingers or get all Jimmy Page and use a bow?
All of these factors have an effect on the original sound, possibly (just for the sake of the argument, discussion or soliloquy we're holding here) something that we could call the terroir of the music. We might also need to factor into the equation the listener's expectations and experience, but why quibble...
Where am I going with this? Who the hell knows?
One of my first amplifier was a Walter Woods bass amp - a 150 watt high power switching amp that weighed about five pounds. I ran it through a variety of speaker cabinets, using what was appropriate for the gig. It was a very transparent amp- clean and direct, transmitted the sound of the bass (62 Jazz usually) perfectly. Then I needed something with more oomph so spent a couple of years playing through a whole bunch of different amps, all of them perfectly adequate but none of them 'right', despite at one time playing through a pair of MacIntosh 3500's. Eventually went back to a higher-wattage Woods amp and it was okay, but the transparency was beginning to bug me. In the studio I'd record directly into the console, and that sense of immediacy and being able to feel the sound was what I really wanted to get out of an amp for live performances. I eventually wound up trying an Aguilar DB359 and THAT was the bass sound I'd always heard in my head (I hear they can treat this now). 200 watts (4 6550 power tubes) and the thing weighs 50+ pounds but it sound so right that it's worth dragging it out to gigs. When I play live these days, from where I stand on stage, my bass sounds the way I think it's supposed to sound. I make it sound good to MY ears and if anyone else has problems with that, they'll tell me, and I'll either turn it down (the usual request) or change the tone settings so the glasses are vibrating off the table, or I'll tell them to sit the fuck down and listen, because I'm an artiste, man.
Is it a transparent amplification? Maybe, because it sounds good regardless of which bass I play through it. The only thing that matters is that it sounds good TO ME, and if that purity of sound encompasses strings rattling across uneven frets, crackly volume pots, or occasionally overdriving the preamp, well, that's just music. The people dancing and drinking and singing along don't much care about the technical stuff, but it's important that I'm laying down parts that make the drummer smile and make it easier for the singer to sing and the guitarist to go dweedle-dweedle-noodle-dweedle, knowing that I'm holding things together. So maybe I'm creating my own musical terroir as I go along, seeing as how music can change according to mood, location, phases of the moon etc...
Sound familiar?
So, let's remove ourselves from bassland and replace the above-mentioned examples with wine crap, and if take a winemaker, well then it would be the sort of winemaker who'd spent a lot of years making wine commercially (but doing it really well, like say a David Vergari or Peter Mathis) who finally had the chance to do make the wines they wanted, the way that they wanted. They're likely to stray only as far from their foundation of knowledge as they have to in order to achieve the wine they've always wanted to make, and sometimes it isn't what others might consider "pure" or "transparent". But this wine contains the sensory triggers that they've always wanted to convey in wine but weren't allowed to. Their skills won't allow them to make any bonehead mistakes (well, most of the time they won't), but they'll be making wine on your own terms. The fan base for these wines will hear about them somewhere and these anti-cult winemakers (ala Steve Edmunds, Mike Dashe, Randall Grahm, et al) may not be living in a palace at the top of a hill in Calistoga, but people will enjoy the wines and the winemakers will be respected on their own terms.
So perhaps it's like "The Wizard of Oz" and we're all just dreaming and that the important stuff is intracranial in nature. All the cultural critics would be out of work if this were true, because everyone would be able to find enjoyment in what they liked, not what they were supposed to like, no?
So maybe there isn't an actual amp analogy in winemaking, but perhaps the entire concept isn't about the conduit of transmission and production, but in our heads. We hear what we want to hear and disregard the rest. Uh, I think someone already sang that. How about you can't please everyone, so you gotta please yourself? Hmmm, maybe that's been used before too. Oh well, in reality, the sound is in the hands and head and heart. Technology helps, but is only really important if you're a salesperson at Guitar Center. With wine, I suspect that a great winemaker could make palatable Pruno where they ever to end up in prison.
-Eden (not sure if any of this makes sense at all, and I can't even blame it on the 2001 Robt Weil Kiedrich Grfenburg Sptlese I'm drinking because it's only 8% alcohol and I've had only one glass)(it's pretty damn transparent though, particularly if you like drinking sweetish apple juice - it's like I've been magically transported to Vermont in the fall....wheeeeee!!)
