Still room for Class A / AB amps with proper heatsinking, Class D for subwoofer


To be honest, I was trying to tell someone that "Down Under" by men at work has a sibilant vocal, it's not his tonearm good lord (lol)

Instead I ended up on the main page without any way to find teh thread and I saw the first bugging er biggun (big thread) was "Class D Taking Over" 

And disagree. There are some totally decent sounding Class D architectures and basically endless power, but I really find high midrange and especially treble sounds better when the amp is in A mode 

It's good to understand, Class B is like a breakup mode, and frankly so is Class D. Class D switches polarity well above the audible range. It has been really fun to design active systems using Class A / AB for >330hz and Class D <330hz (the frequency is approximate, probably closer to 350hz, not a steep slope)

With 70w for bass and 35 / 35 at A / AB for midrange and treble, it's enough for a small listening room.

On more of a "mains" front I'm doing heavily mechanically damped subs with about 700 watts going in per side and then 120 watts <0.5%thd going into an open baffle array on top, glass fiber and titanium coaxial

not sure how to post pics or anything on this site, feel free to hit me up mehta (dot) youngs @gmail.com or 13 0624 4265 0 (call only)

cabinets are scorched pine and cedar, with mdf or cork baffle depending. the mains are bamboo hardwood, ABS, and steel OB and probably not to everyone's taste lol

This was definitely not a successful post haha! Probably due to the lack of focus in my writing above and that it was completely off the cuff. I appreciate the response you gave here. I like this site and should take it more seriously, as people here are very earnest compared to elsewhere in audio land. Thinking to make another post, maybe include some photos.
