the DT50's preamp is basically the same as the POD HD's pre models. the DT50 ALWAYS uses a DSP modelled preamp.
it's the poweramp that's the different bit. the DT50's poweramp reconfigures itself to be the same setup as a real poweramp.
so e.g. on DT50 voicing 3, the preamp is modelling a VOX AC30 preamp, then the DT50's analog poweramp is reconfigured to be like an AC30 tube poweramp. this is when on normal master volume.
if you pull out the master volume on the DT50 is lowers the volume into a sort of home practice level of volume. in that case the power tubes wont do enough to give you the tube tone, so the DSP modells the whole amp (preamp and poweramp) and the DT50's poweramp tubes just make it a bit louder to hear it. that's actually how the spider valves work. they model the whole amp tone, and the SV tubes just amplify that signal as cleanly as possible. obviously they do add a little tube warmth, but it's not quite as good as a real poweramp making all of the poweramp tone.
does that help you???
just remember, POD HD + DT50 will sound identical to just the DT50 on its own. but obviously only when using 4 of the POD HD amps vs the 4 voicings in the DT50 standalone.

Well, no easy answer on that. I will give you my understanding of the DT50/POD HD. Please bear in mind that I am not a technician. I am more a simple guitar player.
Please be aware that LINE6 does not describe how the tonal building between the traditional tube amp technology and the software driven tone building works. So, therefore you will find a lot of "interpretations" on that - here and in other forums (just my subjective thoughts).
The DT50 has a software driven pre amp section. So the amp is a hybrid between a traditional tube amp (analog technology) and a modelling amp (digital technology).
If you play the DT50 you will not here a difference to a traditional tube amp. So modeling technology does not necessarily stands for bad sound quality.
You can run the DT50 in a high volume mode (master volume not pulled out) and in a low volume mode (master volume pulled out). If you run the DT50 with master volume pulled out the DSP part of the overall tone building is higher. Again: this does not mean worse sound quality. The more you increase the master volume the less is the DSP portion in the overall tone building. I found that after 12 o' clock the DSP part is significantly reduced.
If you use a POD/HD to run the DT50 you can use pre amp or full amp models.
If you use pre amp models the modeling part of the overall tone is not that high as if you are using full amp models.
With full amp models the software will emulate the power section of the amp too. Again: this does not mean worse sound quality. In that scenario you can get a good distortion sound at a reasonable volume level.
If you use pre amp models you have to play at high volume levels to get a distorted sound - in that case generated by the tube amp section. This scenario has the least modeling amount. But the consequence is: you have to hit the tubes on a realy high volume level. Using pre amp models does not necessarily mean better sound quality (just my subjective thoughts).
Hope that helps as a starting point. I think other forum user will add additional / may be different infos and thoughts to you.

hanks for the quick response. So I guess unless I'm playing loud, the tubes are not really adding to the tone very much. I don't play all that loud so I'm mostly hearing the software working, I guess. Does anyone know if an attenuator will work on the dt50?

I have no experience with it, but I have seen posts from folks saying they like it. you might be able to search the forums and find the individuals and ask them directly

No personal experience too.
I think this is the link you can get some more infos on attenuator (DR Z) in this forum:
Hope that helps. Rock on!
