How does the POD HD sound when it is used with the Atomic Reactor amp?
Is it worth to get one of those or should i go for a DT 25 amp
The idea of the Atomics was to reproduce the Pod bean (and two or three other similarly sized modelers) as agnostically and in as uncolored a manner as possible while using a tube power amp and a 12" speaker while still looking pretty much like a standard combo amp. Thus the 18W version sports a 200W fairly-flat-response speaker in a large closed-back cabinet (larger than my 2x12 Carvin Belair). The 50W 1x12 is ported, and the 2x12 is closed-back, ported, and only about 4" shorter than a 4x12.
What the Atomics are not (leastways these versions) is an FRFR unit. I've actually added a piezo-based tweeter to one of them to stretch the top end a bit, and I don't know that I'd call them completely flat. They DO do a nice job of presenting the Pods as they are, and I like the idea of having a hot-swappable bay so that you can exchange the various Pods. At first, I thought it was pretty much a waste; I figured it was highly unlikely that I'd be purchasing and using an M-Audio, Behringer or Vox modeler because of something special they offered. Since then, however, I've found myself owning a Pod XT, a Pod X3, a Pod HD and a Bass Pod XT (works really well with the 2x12 for practice), and there are reasons for all four of those to go in at one time or another, and I don't have to bother re-wiring everything to do so. In terms of an FRFR unit, a pair of Rokit 8's works better for nearfield practicing and a pair of fEARless F115s works better for noisy gigs (I run them with a 1500W power amp).
The DT25/50 series have an entirely different mission. They *add* guitar-based amp sounds to what you get with the Pod.
BTW, the Atomic isn't something you'd choose first for the acoustic models; the one thing missing from these is the high end. Add the tweeter and it does work for those. But honestly an FRFR speaker works far better. I dunno about the DT25.
