We can teach you. mwahahahahahaha.It's a good thing I don't know how to crate those comparison graphs.
Admittedly I sold the Recto years ago, never have forgiven myself. I’m going from memory, but I played that amp for years.
The fractal recto2 and helix clip sound more like my memory of my recto than your real amp clip. Mine was a 3 channel triple. It’s possible that my memory is busted, but it could be that you have an unusually bright recto?

High Cut Frequency, wiki says it's the snubber cap on the phase inverter.
Recto has PI snubbers on both plate resistors AND between the out-of-phase outputs.

I've compared this to several other Rectifiers in the room and also basically every emulation out there, and IMO any difference in top end between units is almost certainly related to the master volume. I tend to run my master quite low which allows more bass and top end to come through. If you turn the volume up, they're the first to lose headroom and the tone smooths out. The point really is that the Fractal models SHOULD be able to match the brightness of the real amp. I think if I turned the master up on the real amp and used a flatter load, it might be easier to match. Either way, the Helix can get a similar brightness to my amp (sometimes a bit more because of the artifacts).
So in theory, these should be left alone at their default values?High Cut Frequency, wiki says it's the snubber cap on the phase inverter.

I really have no idea on this one, your guess is as good as mine.

Just for kicks, heres the 5150. WAY closer and easier to match without having to dive into anything advanced (just left that stuff at default for the most part). The main difference I heard with the Fractal vs the amp was actually more in the lows this time, the amp had more WOOMPH on the palm mutes. I turned speaker compression down a bit and speaker thump up but its a bit hard to gauge where the most "correct" value is.
and Helix's often maligned Panama as a control again, this one actually needed funkier settings to get close:

man be careful on the fractal forum,cliff and the fanboys always will say fractal sound better,they will neever admit that another unit sound better than fractal,fractal banned me because i said Kemper and Helix are great unitsI'd be using a Suhr RL and an IR. Wonder what would happen if I hooked up a cab and the Suhr RL (8ohm + 8ohm from the 4ohm outputs on the amp) at the same time? Yeah... not trying that but it would be interesting.
Cliff already blew me up once for not using a decent reactive load...
5150 III 50W vs Kemper vs FM3
I finally received the FM3 and decided to put it up against the Kemper and real amp. A reamped track was used for all of these and recorded through the Two Notes Captor using the same IR with a high cut at 8300. The FM3 controls were set to exactly match the settings on the amp including the...forum.fractalaudio.com

Is it weird that this thread is really putting me into the Christmas spirit? Lol. Because discussions of Recto geekery make me feel like it's Christmas.

How about a Gift of Tone to get you in the mood.

Wait a minute...the Tone X wave form looks radically less compressed than the the other tracks. Looking at it vs the source, that seems a little suspect that it would null test the cleanest. Granted I didn't watch the rest of the vid, only what you highlighted but the visual there doesn't align with what I'm hearing.

Tonex is still really good. Even if IK is shady...

Yeah Tone X is at the top for commercially available capture hardware imo (in terms of accuracy)

Helix palm mutes are massively off to me.

I'm not doubting it's capabilities. I just don't understand what I'm seeing in that vid. 3 tracks look very compressed typically of a high gain amp with a compressor added post amp to even out any palm muting from peaking. But that Tone X signal looks very, very different, way less compressed. If it were a more perfect copy of the original I would expect the wav to have a similar highly compressed visual.
EDIT: NM, went back and watched the setup section. The wav is the direct signal, ToneX is running as a plug not rendered like the rest. That's legit very, very cool.

It should be totally safe to run the reactive load and the cabinet at the same time like you described. Your amp will see the load box as though it is just another speaker cab. I think John Suhr mentioned doin exactly that in an interview saying that it is a way you can use the load box to attenuate the signal being sent to your speaker cab. I wish I could remember the source on that because I would point you towards it.I'd be using a Suhr RL and an IR.

If you're in doubt, email Suhr customer support and they will give you the definitive answer.

These comparisons sometimes feel like "what am I doing?" and then I land on something (often with the help of others) that helps me learn the gear better. Whats awesome is I end up learning just as much about the real gear as I do the digital stuff. and in turn I think by sharing it online it helps others get the most out of the gear. Endless stuff to learn!Super cool that you have both the gear and the knowledge to do stuff like this, Ed.
