Hugh Robjohns Top Ten Interfaces/Convertors?

[Tomás Mulcahy]

Great info, thank Hugh. Much more useful and productive than what ends up happening with a similar Q on a certain other forum

[dylanhughes81]

As promised, here is my list of dynamic range measurements of all the interfaces and converters to have passed across my test bench in recent years

Thanks Hugh, really appreciate you taking the time to dig it out and right some helpful context around it as well.

Very interesting - maybe this could be a sticky?

...maybe this could be a sticky?

Possibly a Top Gear board with a big reveal and magnetic stickers.

That’s revealing…and surprising. I won’t mention any brands here. Anyway, I trust you more than anyone else.

Interesting lists.

Quick questions for Hugh - the Focusrite Rednet and Merging Hapi AD and DA conversion all come in different versions. With Focusrite, it's different hardware boxes, the older series is (mostly) 2U and the newer stuff is 1U with dual PSUs but with the Merging boxes the conversion quality comes down to a choice of input and output cards, of which there are several. Do you know which ones you tested?

[Hugh Robjohns]

Not off the top of my head, but the details will be in the relevant reviews, and you can look those up as easily as I can.

In the case of older reviews, its possible that newer updated converters might be employed in later versions.

The only old/new version i can recall testing were the optional 8-channel A-D cards for Focusrite's ISA428 (and related products), with the updated (current) version being significantly better.

Thanks!

Digital recording is all different degrees of crap.

There is no such thing as a "good" AD/DA converter.

I’ve been away from this forum for four days, glad to see it’s business as usual.

A little surprised the Prismsound Dream convertors didn't feature on that list. I may have missed a criterion though.

[Wonks]

The main one being that Hugh's had them submitted to test. If they aren't submitted and then selected to be testd by the mag and for Hugh to review as opposed to someone else, then I doubt he actively goes out finding units to test for fun.

[ken long]

Fair enough!

Ha! I feared this kind of response...

I have explained, in bold, why the devices I've listed are there, and why other devices are not.

Point one: This list is ONLY of the products that happened to have crossed my test bench. It is categorically NOT a comprehensive list of 'The Best (or worst) Converters and Interfaces', and not a list of recommendations.

There are many brands and specific products that I haven't had the opportunity to measure. Their omission from this list does not imply anything about their performance in any way; I simply haven't tested them (yet).

In fairness the original comment floated off into the distance on its back with all four legs in the air. That's business as usual round here

I'd add to this that different generation products from the same manufacturer can be very different — so do pay attention to the review dates that Hugh thoughtfully included in his post!

Eg he tested the first-gen UA Apollo and quoted the figures for that in his table, but UA's claims of their latest-generation Apollos would, if confirmed accurate, put those interfaces at the top of the list. I'm sure some others have made significant leaps too...

[Hugh Robjohns]

Good point, and I've extended the intro slightly to make that clear.

For me, the biggest take away is that there is a 20dB difference in performance between the worst and best models to have passed across my test bench.

Although the very best performers are generally the most expensive models, and the very worst the least expensive -- much as you might expect -- a surprisingly high number of affordable devices manage to deliver extremely good figures, which is encouraging. And even the worst is still capable of high quality results in practical home-studio circumstances.

Not that it matters, but I'll soon be buying the new RME AIO Pro. Your (Hugh)'s review in July stated that "the AIO‑Pro sits just inside my top 10 rankings". Any reason it's not on this list? Because it's essentially the same circuitry as the ADI-2 perhaps?

[Hugh Robjohns]

Any reason it's not on this list?

incompetence, mainly.

Apologies, both the original and the pro cards scores fell off my chart! Now added back in.

I feel a bit of a twerp for mentioning it- it’s just that it had stuck in my mind since I read the review a few times as I was seriously contemplating buying one.
