I ask because I've got an Orange TH30 mini stack (2 x 112's) which I've just got back as it blew up just before NYE and I've just today setup the 4cm. I'm running the 'real' tube preamps (clean/dirty) and using some patches from the HD500 (Recto, Deluxe reverb etc) as comparisons and so far I'm pretty impressed with the setup. I've got the Recto and the DR sounding pretty solid (I'm a long tweaker with the HD series as this is my second HD500 and I've owned a HD300 before that) and whilst the modelled pre's/fx chains sound pretty bloody good, they don't sound as good as the real preamp; espec with some HD500 'magic' (EQ, Verb, Delay etc) thrown into the mix. As I wouldn't be able to compare these rigs side by side, would the DT25 sound better than this current setup or does it essentially sound like a well tweaked HD500 running into a 'nice', well matched power section? For reference, the TH30 has a great 4 tube 30 watt EL84 power section which is switchable to 2 tubes 15 watts, 4 tubes 15 watts and 2 tubes 7 watts so whilst it can't do Class A, it does that EL84 class A/B but it can do pentode/triode and also run with 4 and 2 tubes which is definitely a trick the DT can't do. Plus it should have more headroom than the DT as it uses 4 tubes and doesn't claim to be putting out 25 watts per pair of EL84s. I liked the DT50 I test drove but if I'm not going to get better tones I'll sit tight and save myself $1200. What are your experiences running this way? Have any owners tried their DT's into good amps/poweramps and found they are similar to the HD+DT combination? I have to admit to also being a little worried about the L6 depreciation factor. If I pay $1200, it'll be only worth $600 next year if I want to sell it where the Orange will still command ~$850 and I only paid $1050.
