Soooooo good

Which makes sense to me as a speaker has its own EQ curve (frequency response), a preamp has EQ control of varying degrees of complexity, power sections are usually just loudeners but to a much lesser extent can add a little flavourrobthemac wrote: ↑Sat Mar 30, 2024 7:39 am Reinforcing my belief that speaker, preamp and then power section are the most influential elements of an amp.

Yep, agree that it makes a difference (as demonstrated in this video), just in most use cases less of a difference than preamp or speakers.Aquila Rossa wrote: ↑Sat Mar 30, 2024 10:49 amjeremyb wrote: ↑Sat Mar 30, 2024 7:44 amWhich makes sense to me as a speaker has its own EQ curve (frequency response), a preamp has EQ control of varying degrees of complexity, power sections are usually just loudeners but to a much lesser extent can add a little flavourrobthemac wrote: ↑Sat Mar 30, 2024 7:39 am Reinforcing my belief that speaker, preamp and then power section are the most influential elements of an amp.

A power amp just makes it louder and can clip and compress, but how the output transformer and speaker interacts is important for how the amp sounds and behaves. Stuff like response time and damping etc. Guitar speakers do not just instantly stop when signal stops running to them. For a split second they keep moving. A transformer and speaker combination with higher damping stops producing sound sooner. It sounds tighter and more precise. Same with response and how quickly they respond to signal. Some designs respond faster. Not that we necessarily want either. Depends on the tone and feel you are after. Perfect hi-fi specs tend to suck for guitar.
Sag is another thing in the power amp. Can the power supply keep up with demand. If it can't your tone's price increases
Don't forget negative feedback. It can be used to cancel out stuff you do not want in the tone of the amp, or let stuff through, e.g., presence and depth etc.
