I've owned a Spider IV 30 a a practice amp for many years and decided to look at a newer larger version. I recently purchased a Spider V and road tested the 60, 120 and 240 very carefully. I played them side-by-side with the same model guitar, preset-by-preset, and all handled volume well enough at very low "bedroom" levels, but as you gradually increase the volume the quality differences become more and more apparent. Even though I primarily play this at home, I settled on the 240 because the sound quality was simply better to me.
