Traditionally tube amplifiers will give you a distorted to warm fat sound. They usually have much more punch than the other types of amplifiers. Tube amplifiers are also more expensive to maintain and can be somewhat problematic. Tubes are getting hard to find these days. Especially USA made tubes. The Ampeg SVT is an example of a powerhouse tube amplifier. Older Fender amps like the Bassman are tube amps.
Solid State Amps
Solid state, meaning no tubes, amplifiers will give you a bright almost tinny sound and more of an artificial sounding bottom end. The solid state also gives you a very clean sound. These amplifiers are generally more reliable and are less expensive getting them back out of the repair shop. Solid state amps include Peavy and Galleon Kruger.
The typical hybrid amplifiers will have a tube pre-amp and a solid state power amplifier. This gives you the warm sound of the tube amplifiers and the clean crispiness of the solid state amplifiers. The hybrids can give you the more versatility than the other types of amplifiers.
i copied the above from some sites...hope it explains simply those terms. :P
nah cables are great fun...u will get to it sooner or later...its not yokohama...i play with hankook tyres.
Any kind of amp can sound like anything. Warm and lush, neutral (wire with gain), or bright and tinny. An amp should, in theory, amplify the volume of the source without changing it in any way. Unfortunately, no amp is perfect, and many of them (even those promoted and loved in these forums) don't even come close.
Too many folks here waste hundreds (or thousands) of dollars first buying a pair of headphones and then "tuning" the sound with different amps, tubes, opamps, cables, power conditioners, pyramids, prayer beads, and silly hats.
The need to even have an amplifier is highly overstated on the forums. The HD 600 is rated at 97 dB at 1 mW. That means that with one one-thousandth of one watt, the HD 600 puts out 97 decibels of sound pressure. That's about as loud as a chain saw, pneumatic drill, or a jackhammer.
