Amplification: what are the biggest advances of the last 40 years?
Active speakers are a good example of how Class D enables things not possible before.  My little but over performing  Vanatoo active speakers are biamped with two Class D amps in each.  
Amplification: what are the biggest advances of the last 40 years?
More efficient amplifiers ie Class D and similar. Also the ability to control noise with same. That’s the big one by a huge margin that makes things possible that were not prior including beefier amps in a smaller more cost effective  package. Int... 
Rank the tweaks, geeks!
I’ll leave it at there is only two things on that list I have not bothered to dabble with (risers and caps) and one I dabbled with that turned out to not be worth it (fuses).  Also dabbling with fuses can cause damage if not done properly. I let m... 
Considerations prior to your next purchase
Keep telling yourself you can hear ultrasonic frequencies and the fact that you can’t won’t really matter. 
Considerations prior to your next purchase
Well old guys don’t have very good hearing.  That’s a fact.  Take it for what it’s worth. 
What's your dream speaker?
I’m good at the moment.  Have been for a number of years now. 
Is D for Dry? Class D...
It’s nice all the Class D detractors have a thread to dump in. As you can see there are so many of them (detractors).  Maybe a dozen or so.  Meanwhile sales of Class D based gear continue to skyrocket. Go figure. Alternate realities don’t seem to ... 
Distributed Bass Array configuration
I find in practice extremely minor adjustments to my sub level are needed to get it tuned in exactly to my ears, which is consistent with what Duke is saying. Very minor.... 
As you have moved on, are there any items you remember fondly...or most fondly?
Tandberg TR-2080 receiver, Aiwa AD-6550 cassette deck, Philips 312 turntable, Dynaudio Contour Monitors, Magnepan MGIIIa speakers.   
Distributed Bass Array configuration
I have found the best and most efficient way to set up a sub is to measure first to get things in the ball park and then fine tune by ear from there. What I get out of the whole DBA thing is measure before doing anything. It may be a waste if peak... 
Audiophile quality fuse holders
Audiophiles agree on practically nothing including fuse holders.But it never hurts to overbuild and charge accordingly if your goal is to sell to audiophiles. That kinda makes it audiophile at that point. Although most likely audiophiles probably ... 
Low-sensitivity speakers — What's special about them?
If you want or need smaller speakers for whatever reason I’d say that is certainly special.   So is higher efficiency that does not ask as much of an amp.  Two different things.   Both special but in different ways for different purposes.   I will... 
Distributed Bass Array configuration
I think its a fallacy if some are asserting setting up multiple subs properly is easier than one. That’s pretty simple math. You now have more adjustments to deal with and each one has some effect on the resulting sound. You can gloss that over to... 
Low-sensitivity speakers — What's special about them?
It's a perfectly valid question.All designs have advantages and disadvantages.   That goes for both high efficiency and low efficiency speakers. 
Low-sensitivity speakers — What's special about them?
The benefit if done well (like Dynaudio in general) is more bass extension from a smaller box, but you need a beefier amp than otherwise typically to be able to deliver that bass. Power needs increase exponentially with lower frequency.Its easy to...
