If someone sends a Magni2 to Tom, I'm sure he'd be happy to measure it when time allows.
I should reiterate right now that the side-by-side measurement charts were compiled by me. Tom makes no mention of any of his work when discussing the measurements of the O2. He has also posted a small addendum by JDS Labs and amended portions of his text to reflect that.
You bet. I'll be happy to measure the Magni2 or any other product that makes for a good comparison with the HP-1. I'll have a pretty darn open schedule from mid April to early September, so that would be a good time. I do the work. You pay the shipping.
I can obviously easily be accused of bias. I would also point out that I am a human being (this fact has been independently verified), thus, suffer from the same cognitive biases as every other human being. That said, in my evaluations of other products I do my best to be fair and base my arguments on science, engineering, and measurements. I am not here to rag on anybody or any product. I understand NwAvGuy did that and while I didn't personally witness that, I have absolutely no intention of replicating that as that would reflect poorly on me and my business.
In case of the O2, I have provided all the data I took. Anyone can scroll through the plots without reading the text and draw their own conclusions. Should your conclusion be different than mine, that's fine. The text of the review is obviously my subjective opinion based on my interpretation of the data and my experience with the product. I do my best to keep my critique fair and science/engineering based.
I think there's one question floating around out there: Is the O2 worth the money? If you're a tinkerer who knows how to use a soldering iron but don't have any circuit design skills much beyond that, I think the O2 would be a fun project to tackle. There's plenty of options for tweaking. I mention the possibility of "rolling" opamps in my review, for example. If you, like I, have strong circuit design skills or want something higher end, I think you'd be better off putting your $120 towards another project.
If you do decide to buy an O2, I definitely recommend JDS Labs. They're rock solid.
