Yes....in the right signal chain and specific situation, and in the right hands, they will sound better than most $200 preamps, a lot of the time. Only thing those "blind" comparisons do is show that each person has a different opinion about what they are hearing, there is little real consensus on what is "better" in a given situation....but when you're squeezing the wallet, and wondering if you can afford to drop a $1000+ on
a preamp, it may be hard for some people to take that step and spend that much money on one item. There’s people here who want to have a pro studio and get pro results….on a $500 total budget, and they get very offended if someone tells them it can’t be done.
If you are going to buy an expensive preamp, and the rest of your signal chain is so-so....then you won't get much out of it.
Also, you need to know what you are listening for when comparing preamps and what a high-end pre does for the signal.
The problem is that some people think a high-end pre will magically improve the signal in a very big, noticeable way, and because it's more money, the sound quality will be proportionally better per dollar.....and when they are not blown away, they believe that the high-end pre was a waste of money.
It can be a subtle thing, but when combined with the right mic and the rest of your signal chain and production....it makes a difference.
People can look for reasons to deny that, but getting opinions on what's the best gear on a home rec forum often ends up with the majority going for the inexpensive stuff, and then often there's the follow up argument,
"it's only home recording, and I'm just recording for fun".
Well...that's fine, no one is saying you have to compete with pro studios ....but you'll never match the sound quality of a high-end signal chain and production process of a pro studio...with a $50 mic, $200 pre and $100 interface going to a laptop in the corner of your bedroom, no matter how "experienced" you are. You certainly don't have to try and match it....but then what's the point of even asking about high-end pres?
There was a thread around here just recently, where someone was asking another member how they got that specific vocal sound that was on a lot of their YT videos. When the guy finally responded and listed about $20k worth of signal chain.....the thread died quickly.
Now, you don't need a $20k signal chain....but you ain't gonna' do it with $200.
As I said in the other thread....you might need to try out several preamps....have them in your hands, in your studio, spend some time recording with them, using different mics on different sources, and then seeing how all that gels in the mix...and finally THEN you might understand what's better/worse about preamp A or B or C....and then keep the ones you like and sell the ones you don't. I doubt many people do that, or have the opportunity....so it comes down to maybe one pre that they bought and tried, or what other people have said on some forum about a given pre....which is not going to give you a clear answer or understanding what makes one pre the better choice or not....regardless of the price.
