That's an interesting point...
..and one that's been the centre of many a heated discussion on many recording BBS - high-end vs budget pre-amps...how big is the difference?
I'll try to give my humble opinion and my reason for forming it, without starting a war here

. Once upon a time, I was using a budget pre-amp retailing around the $150 mark. In conjuntion with a RODE NT2 mic on vocals, it sounded, well, OK. It was certainly an improvement on using only the in-built pres on my mixer. Later on, I became the proud owner of an Avalon 737. Yes there was a difference, but at the start I was scratching my head wondering why it didn't sound 10 times better, because it cost 10 times as much! It certainly sounded (excuse the cliches) fuller, warmer, deeper, wider, bigger, punchier, smoother, etc, etc, but it didn't sound $2000 bucks better than the budget unit I had used in the past. The difference was subtle, and one had to listen extemely carefully, preferably through a set of cans, to hear these subtleties. All in all, I could honestly say that the sound improvement on an individual sound source was around 10 to 20% better with the Avalon. Hmmm....
Then I used the Avalon to re-recorded a song that I'd done a few days earlier with the budget pre. Snare through the Avalon, Kick through the Avalon. Keys through the Avalon, Bass through the Avalon, Guitars throuh the Avalon, Vocals through the Avalon. Once I'd finished the mixdown I couldn't believe my ears. When I compared the 2 units it became clear to me where the extra money had gone. The difference was astounding. That "pro" sound I'd been searching for all those years, coming close to, but never quite achieving, was suddenly there. The admittedly iniitially disapointing"only" 10% to 20% improvement on each individual sound source, on each track, seemed to add up to an improvement of 100 to 200% percent on a total mix. I can't describe the feeling I got. It's a bit like your first orgasm all over again. I do know that my hands started to sweat and my heart was beating like I'd just run 110 yards in 9 seconds flat.
I ordered a second Avalon a month later...took me almost a year to pay off
Now a few years later, one valuable lesson I learnt is that THE most important part of the entire signal chain is a high quality front end (i.e. mics and pre-amps). I found that a lot of high-end pre amps will expose deficiencies in some "budget" condensor mics. One can achieve a pro sound with an average mixer, digital tape or DAW, as long as one has a pro quality front end......although it helps if you can mix a bit too

It's almost impossible to get that pro sound without a great front end to your signal chain. Unfortunately for most of us, a decent front end doesn't come cheap

Therefore, bite the bullet, sacrifice where you can, and accept no compromise. You'll just be upgrading later anyway....
...just my mad rumblings of an explaination
