^^ it is though, and as greg somewhat pointed out, you can make do with less high end gear if you know how to work it. Its cool if you have a lot of money but you're still a fool to solve your error with a piece of gear that would fix your problem. Granted, some mics sometimes dont work out, but it has nothing to do with the pricetag or legacy of such a product.
here the thing for me with analog; it does sound better considering all the pieces have their own signature sound opposed to everything sound like your converters. Plugin's can provide features you cant obtain in the analog domain (if so, its mad expensive), i think those plugs are valuable, stuff like Rob Paapen's Blade are truly unique.
I dont bother about wether or not people could recognize the difference, but its like a palette of colours working on a canvas. Is it relevant to score ? No, but some people do know the differences and set out their preferences that way and others are not willing to go that route because it is expensive to gain the same amount of options (not to mention the amount and quality of i/o you need).
Second, hand's on control. Buttons, knobs and whatnot for dedicated features result to a more intuitive approach on synths, outboard and also mpc's and the likes. If i dont need to look at the screen it means i'm using my ears better. On the creative side, im using synth better when theyre analog, its intuitive and often so much i dont even use a sequencer or use automation. Having 10 fingers to play and tweak with one machine is really something else and i know i can use my midi controllers to gain the same hands on control but the reality is that you dont have enough knobs or those knobs arent as logical as knowing a real synth inside out.
3rd, For beginners wanting to learn. I started out some 25years ago and having a real piece of anything makes you understand much faster than what it does. All the virtual stuff gives you a bigger learning curve which imo, makes it harder to understand/learn. That being said, the possibility to have all things virtual does grant you acces to things you couldnt afford to buy 25 years ago
, but if i take a typical formant based synth and give it to a noob he'd probably know more about sound design in a year opposed to one with a plugin.
As for virtual outboard, processing; This is where digital shines, especialy in the dynamic processing where coloration/saturation isnt needed. Coloration/saturation i think is being overused, to compensate or by not even realising that either is added in the signal. For samplism you most likely wont need either, for dry material and working itb its a good solution but it really depends on your project. Sometimes its just fixing something you couldve solved during the recording instead of "touching up".
A lot of things is plain marketing aswell, you can take an api2500 plugin and the real thing and it would be easy to say that the plugin sounds good. It cant beat the real api2500, it really didnt get me as much.
Then there are impulse responses which actualy do sound really nice. Last year we rented a battery of rev. F 1176 for a project and we took an IR. After the project we compared the same material and the real 1176 takes were richer but if you dont have it, the IR wasnt all that bad at all as an alternative. Its just knowing the difference that puts you off with these kinda thing.
Then again, top of the line high end digital processing -> TC 6k, Weiss. All dsp products in hardware format with no plugin format alternatives that come close.
