To me, the 30 sounds more dynamic and punchy than the 15, in the comparisons I've heard, the 15 being slightly more compressed. I suspect having to do with the power section, as I'd imagine the preamps are probably identical. Putting the NOS Russian power tubes in my 15 did bring back some of that openness, but not all the way. Not that it's by any means a bad sounding amp, it's fantastic, I just don't have any illusions that it can equal the build and tone of the 30, with the way they make that amp. For someone wanting that basic tone with less volume, weight and size, I'd say it'll probably make a person very happy, it does for me.
A large part, for me, was the footswitching options as well. I used mine live a couple weeks ago and it was perfect. I had the base tone clean, and the boost with light breakup and tamed slightly by the master w/boost option, mostly using pedals for dirtier sounds, and time based effects into the front. Very functional amp, I can definitely tell that it was designed by and for someone who is gigging. I don't mind the "compromises" (mild as they are) at all considering the features.
The cab is a little killer, too. I think it's pine, it's certainly very light, and sounds excellent. I don't always get along with V30's, but this one is done right.
I used my Two Notes rig (Cab M/Captor) for silent stage at that event, love it! I profile my cabinets and run them through the IR loader, which I appreciate how easy it is with the Two Notes ecosystem, and use some of the DynIR's too.
Your company should try to get together with PRS and explore putting a reactive load and IR loader in their amps. I know they're pretty strict on keeping things old school and straightforward on their amps, and I appreciate that. But, from another perspective, it's a feature that will make it convenient to keep using tube amps in environments where blasting a cabinet and getting the amp working like it should just isn't allowed. Especially on their smaller amps that are designed to be a grab and go - I'd love to have a load and IR capability in the DGT15, HDRX 20, MT15, I'm already using the tech with them anyway.
