Mackie and Behringer use the same Op-Amps inside'
Mackie and Behringer use the same Op-Amps inside', I believe them to be the 4580 operational amplifiers, older Mackie mixers might have used the 4560 Op Amps.
Anyways I have done a comparison of the two mixer companies, A/B comparison of Mackie and Behringer, and I think the Behringer sounds just as good or better than Mackie, I am sorry to say that Mackie is just way too overpriced, even used on eBay.
I have bought some Behringer mixers used MX802a, MX1604a, and the top line MX-9000. I am happy with all of them. They need maintenance after 8 years like using CAIG DE-OX-IT spray cleaner/lubricant on the faders, pots, switches every 8 years or so, just like all studio and stereo gear, even the Mackie's and especially the Mackie mixers need allot of TLC in that regard, and their internal ribbon cables go bad by oxidation.
Apparently Behringer also uses Panasonic faders and Switchcraft potentiometers parts.
I don't know what Mackie uses. But I know the new Mackie mixers I have tried feel very loose on all their knobs and faders. Can I say cheaply made?
Soundcraft and Allen & Heath mixers blow away Mackie and Behringer any day of the week, and cost just a little more than the way over priced Mackie mixers. Mackie is just way too hyped and slick advertising and humor.
I would go with Behringer for good value and price, and then if you want, step up to maybe Allen & Heath or equivalent.
Stay away from Mackie, they are not built like tanks and are not reliable as the Gestapo propaganda dictates'.
If you have the money to spend on Mackie go with a better brand, don't waste your money. Mackie is like the way high overpriced Behringer with no difference in sound quality or build, in my opinion.
If you don't believe me, try a Mackie in the store and feel the quality or lack of it. Compare it to Allen & Heath, no comparison !!! Price is close though.
I tried Mackie's new XLR mic pre amps, they sound well...exactly like Behringer.
Why bother............I am saving my money for a better musical instrument, effects, drums, keyboards, computer system, software etc.
