Dynamic Range of a "Real" Tube Amp -vs- Modeler ?

I very basically understand what DR range is, but and am still confused about its impact on guitar playing dynamics and response etc...

=> the Axe / Helix have -what I believe- are very good dynamic ranges of something in the order of ~123db give or take and to me, they both sound and feel great

But for relative-comparison purposes:-

1 => if you look at a classic, say, "industry standard" real tube amp like say an AC30 or Deluxe Reverb or Plexi - is it possible to ascribe to them a dynamic range figure that makes sense when compared to the above-mentioned DR values for these 2 modelers (?)

2 => also, does a lower DR on a modeler "mainly" have the impact of increasing the noise floor -and therefore- "crowding out" to a small degree, some of the guitar playing dynamics and response etc... (?)

For example - with my DSH Humboldt Simplifer X Analog Pedal in the Loop of my HX Stomp - when turned up and with the guitar volume rolled totally off, there is quite a bit of hiss. The exact same preset with the Loop disengaged and the HX Marshall 2203 in its place with the same volume and gain ... with the guitar volume rolled totally off, there is zero noise (?)

Yet they both sound and feel great when actually played with my guitar volume oscillating between 8 - 10 (?)

And, there is no spec in the DSM Simplifier X Manual where I can see what DR it has (?)

What you’re describing here may or may not be attributed to the HX loop not playing nice with the simplifier. There are some noise interactions that have been noted on Helix devices, particularly with devices that add gain in the loop or after a conversion stage. I’m honestly not sure if the stomp also suffers from this but it wouldn’t surprise me.

Dynamic range is the difference between the floor noise level and the highest signal the system can output, so you can definitely measure it on any kind of equipment, but I seriously doubt that a tube amp can have a higher dynamic range than any modern audio interface/modeler.

Anyway, in a guitar rig the "bottleneck" is not the amp or modeler for sure, but rather the guitar itself and the EMI it picks up from the environment. Even with active or noiseless pickups you can't go much further than 50-60 dB of S/N ratio.

Btw @BenIfin , I just found this interesting thread on the subject that you started not too long ago:

Yeah - I re-read it before posting again as I was still confused ...... by myself :)
