I expect a high quality model to need more resources, that's for sure, and something like this has to account for arbitrary parameter changes in a way that something like Tonex does not.DerKastellan wrote: Thu Dec 04, 2025 5:22 pm I played around with DDMF PluginDoctor to make this a bit more objective than me trying to read my DAW's CPU meter.
Here's some Helix Native preset vs. loading the Ruby in Paradise Studio:

The upper line is the UA Paradise Studio.
As for what it means:
So, the UA takes significantly longer to process the buffers.Performance: how many milliseconds are really spent in your plugin’s audio processing callback (as a function of buffer size)
For comparison, here is the UA Ruby plugin (also top, bottom line still Line 6):

The version in the Paradise Studio is significantly faster! (But still heavy in terms of processing time.)
It's funny seeing the faster plugin update the line several times while the slower one is still busy rendering the line once.

This, of course, says nothing about the quality, the dynamic response, the closeness to a particular original unit, etc. But you need a bit more oomph to run it.
So, I spent the morning doing more of a "deep dive," and boy oh boy, that is difficult. So many different factors that have to be accounted for. I was literally running sine waves though them and trying to match harmonics.
My end feelings are, based on only the Lion model and various IK Marshall models, is that the UAD is plain and simply a bit better when it comes to dynamics. There's just something a bit more natural sounding about it, while the Amplitube models seem like they're being compressed and a bit band limited. That said... who doesn't like to compress their guitar a bit? In a mix, the Amplitube really stood out nicely without anything. It does have a very mid-forward tone, which is great for someone like me who does a lot of synth stuff as well. I put it on a busy track that I just finished mixing and it took a lot of EQ to make it fit in the track, compared to the previous plugin, which was just Tonex.
No doubt that I got great sounds from Amplitube, but when you really compare them, I've got to admit that the extra CPU cycles that UAD are using are doing something. If you're into classic sounds and guitars are featured in a sparse mix, it's worth it. I sort of wish it wasn't just classic amps, and there were some high gain models in there, like at least an SLO-100 or Triple Rectifier. As my friend Dee would say, "I want to rock."
So, for fun, because everyone knows me as a paragon of all that is fun, I put some Super Lead captures from Tonex against Lion. Now the difference is not as apparent, or maybe none. Hard to say because there's no way to know how the amp was set up, mics, etc. Just going on a general idea of quality and vibe, I'd say that Tonex is on par with Lion. So, that's great, but it means going though captures instead of just loading up a model and setting it up as you'd like. There's tweaking to be done in Tonex, for sure, but it's just not the same. That said, I found something that was pretty close to what I'd set up Lion to do in about 6 tries, which probably took less time than setting up something myself.
So, to close, I preferred Amplitube when I wanted something modern and tight. I could never really get Paradise to get there with boosts, EQ or gain effects. I also miss being able to just "move a mic around" to find a sweet spot. It would be nice if I could load my own IRs into it, as well. I found a bug with the volume effect where it seems to go from -60 db to infinite and if you've got some gain stuff happening, you get a bump when controlling it with a MIDI pedal (FCB1010) Super annoying. I also love Amplitube's room convolution. It's seriously great and no one has anything nearly as good.
I preferred Paradise when I wanted something more 60s-70s vintage sounding. There's something loose and natural about the sound that's really pleasing in some respects. Harder to fit in a busy mix, but on it's own, it was beautiful sounding. Maybe I will plunk down the $99 for it. What else am I going to do with my money? Save it?
