Default Real World Gear Tests - Direct Boxes

I have been working on tests of claims by the Marketing Machine, forum "experts" and audio industry "educators"

I am especially tired of newcomers to our communities being told they have to spend tens of thousands of dollars on basic devices just to do basic recordings.

I was very curious about just how much "character" devices actually impart. Just how non linear are they?

I couldn't find an apples to apples comparison, so I have begun working on one. Here is the first one on Direct Boxes (so far)

Well somehow I've never seen this? Anybody with a few hundred bucks and a few thousand hours can do great recordings at home.

As far as the DI boxes that you would use on a stage, or on the floor of your studio, varying percentages of the cost goes towards build quality as well as internal components, which skews the "you get what you pay for" argument to some degree...

I have a cheap (inexpensive) Hosa passive DI box that I cannot hear any appreciable difference in sound quality as compared to my more expensive but built-like-a-tank Radial passive DI (the ProDI, not the premium JDI)...the only difference for me is that I would not take the Hosa out on the road...

I'd have to say that good AD/DA trumps a good DI unless it's a necessary part of the equation.

In other words A good DI won't necessarily improve your signal if your interface already has the correct inputs for your source.

Wait till you see the A to D charts! Lots of suprises there.

And no, the deviation between DI boxes is MILES above the deviation between any decent Analog to Digital converter (including even the oft crapped upon Behringer ADA8000)

Thanks for the tests... Just an aside/side comment for everyone else... one doesn't even need a direct box to record 99% of the time.

I wish you wouldn't call interface instrument inputs DIs, they are just hi-z inputs and just like a stomp box input which is essentially exactly the same isn't called a DI. I know we disagree, they do similar jobs, and it's plausible to argue, but they aren't exactly the same thing - that has nothing to do with these tests (it doesn't affect them), we just need to separate them in discussions to avoid confusion IMHO.

Well in this case, the Rapco and the Radial are built like absolute tanks, and the 325 is so fragile you wouldn't dare take it on stage, so still, from that parameter, cheaper isn't just better, its MUCH better
