I use nick crow's 8505 through my marshall 1960a for practising and I think it's pretty beast. Not as good as a real 5150 but at least I don't have to buy a power attenuator to be able to get 5150 kinda tones at a lower volume.
I've been using the Poulin Legion amp and I'm pretty impressed (I'm using it with Recabinet). As far as tone and feel, and if you're playing through high quality monitors (KRK Rokits!) then it's really close to playing through a tube, IMO.
+1 for Poulins sims
I find it much easier to get a decent tone from a good ampsim/impulses than micing a cab.
I tried Marke IV, Triaxis, Engl Savage 60 & 120, Blackmore, Mesa Preamp, Poweramps, Marshall cabs, Engl Cabs, mesa Cabs... all the combinations between them and still can't get a punchy ass-ripping tone as I do with TSE X30 or X50.
I'm retarded.
+ 10 to Onqel's TSE sims
I find it really hard to believe that there are some guys here that get much better tones with amp sims than real amps. I know that right now my current real amp setup is dead simple and without even trying sounds more godly than me spending hours trying to get a half decent sound with amp sims. It actually takes me longer just to set up an amp sim chain in a blank DAW session than it takes to turn on my already mic'd amp and turn on my mic preamp. The reality is, you don't need cranked volumes to get great results with any tube amp, although a tube amp at full volume would sound better. I have found that with the right mic position (and its not that difficult) and the right amp settings, you can get much better tones with a real amp than you ever could with any amp sim even at bedroom volumes or i can't wake up anyone else in the house or the neighbors when I am jamming out at 2 in the morning volumes.
