Care to weigh in with your EE knowledge. Can you expound on the differences between different class topologies and the affect of THD on signal waveforms?

Oh my ******* god you are dense. You do know there are different kinds of distortion right? Clipping, crossover? That's not the same thing.

holy **** this dude is a JACKASS.. someone kindly tell him STFU

its bad enough i have to deal with the rest of the morons.

I'm not particularly familiar precisely of what you are talking about, but I suss from what you wrote you are asking me to comment on the different forms ("class topologies" to use ten penny words) of THD has on signal waveforms. I;d have to read up on it a mit, but I guarantee I have the background education to cogently discus the subject!

Start reading fudge cake.. Last time we talked you was fimilar with electrical drdrawinsaka prints.

Well it would be interesting to hear the differences explained by someone with a formal background in EE.

Also if you don't mind can you explain the electrical theory between using bipolar transistors vs using mosfets? I've always been intrigued behind the decision to use one or the other for a high quality amplifier where costs don't play such a large role in the design decision.

I know a trap when I see one being set for me. Go fish!

No, I have a legitimate curiosity. As far as I know you are the only one currently active on the forum with an electrical engineering degree. You have the formal expertise to make significant contributions to technical discussions. I'm hoping you can be the change you want to see in the forum.

I'd think the actual difference between bipolar vs. MOSFET transistors in audio amplifiers would be a wash for most applications. But I'm sure some would find great justifications in using one or the other. Vacuum tubes on the other hand have some great advantages for audio amplifiers. Much more resilient about being over driven

Just to clear stuff up with the great one.

I'm not saying everything is snake oil. But most stuff is. Like speaker wire and RCAs.

No all amps are not the same. But 1w will always sound like 1w.

The speakers themselves have a much larger role to play in terms of distortions.

I once thought like you, I had to buy expensive, large, inefficient amps to have good SQ.

Tune a SQ car and you won't think that way anymore. You will learn they are pointless and completely unnessicary.

Building and tuning this car has opened up my eyes more then any other build since 1994

There's a guy on the diyma forum that actually makes tube amplifiers. I've thought about picking one up to play around with.

Get one! Play with it! Report your results, we may all thank you!
