thank you friend. this explains why people have said the tone king is dull sounding.

Look like the epic comparison is in the pipeline. Can't wait for more, cheers.

I always love your stuff and style, Wolfgang, don't give up, my friend. 🍻🫂🎸♥️

Thanks for saving me a lot disappointment. I was going to buy a captor x for bass use, but that low cut is a no go. Think I’ll get the suhr.

Thanks, great approach and interesting data.

Hi. Line out, I own a Soldano SLO 30 with a Line out, sound is good into the daw with an IR inside, but i want to know if there is a difference with a load Box, since Load Box receives amplifier signal from speaker outlet. Any Information about it? thanks in advance.

I think the overall impedance curve of these units needs to be taken into account together with input vs output, as you wouldn't see them on a test like this. I wonder if some of them tuned that together with their impedance response to make it hit a certain target together.

I guess Koch Loadbox has a reactive element in it and has a pretty sophisticated DI section - I would be interested to see how it compares....

Very informative! Thank you!

Klasse Test! Ich bin gespannt auf das letzte Video. Im Moment suche ich einen Attenuator für meinen 1968 Marshall superbass. Am besten möchte ich damit dich aufnehmen können. Was würdest du da empfehlen? Danke und Grüße

I'd buy an Ironman if it had a loop. I have a Fryette, which does have one, but now I have more tubes to worry about; and I don't need to boost my volumes, so all I need is attenuation, a loop, and ohm matching. The Red Seven has a loop, but it doesn't have ohm matching. Is nothing perfect? I could use a Red Seven along with a Weber Z-Matcher, however.

frequency response is one thing but dynamic response is more important imo especially when it comes to amp reactive load . measuring machine or plugin can only tell you very small % of the sound as a whole , only your ears can tell you if it sounds better or not .

thank you for this comparison! looking forward to Part 2 will you add some sound samples for comparison?

subbed. very informative

hey Dude, incredible video, I have a suhr reactive loud iR, do you think the Ox could be a good jump? I read something about the impendance curve of the suhr being closer to a real speaker, John suhr mentions that some out there have a U-shaped curve that can be dangerous for tubes and transformers, did you do this impendance curve test on the Ox ? Do you know if it is close to Suhr? thanks : )

How do you explain the difference in the frequency response of the white noise at the output of the amp before you do the subtractive difference operation? Some of these have a curve with a scoop at 500hz where others do not. Can this contribute to the tone of the loadbox?

In ideal world Germans are doing quality analysis. Great job!

There is no comparison- Powerstation is the goat

Wouldn't pink noise have been better?

This is an interesting comparison. The issue is you don't know if the Line out is accurate. There is an analog process on your Line out that you don't know. You don't have the Real original signal getting out of the power amp so it is impossible to make a good comparison.

heavy nerdy stuff

there's only a couple in the list that provide a proper IC curve. the rest is just trash
