[QUOTE="chipwelder, post: 95937, member: 54"] At entry level the difference between comparable amps are not THAT big... The power rating - as used by a lot of manufacturers make very little difference to the sound. If it is enough it is enough. The attention to detail i.t.o Power supply and filtering is often quite important at entry level as this is where most cost cutting happens. Most likely the bias current makes a difference to the sound - in the case of class A/B amps. As this makes a bit of a diff's i.t.o. the heatsink sizing etc. Higher up in the range one gets to signature sounds, which is not quite the same as colouration, although it may sound that way, as it is not necessarily the tonal balance that changes, but often the sound depends a lot on what the designer's personal pet-loves and hates in the sound is. So they take especially care of the: 1. Power reserves 2. Impedance capacity 3. Slew rate 4. Some tonal qualities in the exotic stuff. 5. Low component count. and the list goes on... [/QUOTE]
