@rh67Thank you!
Class D amps seem poised to take over. Then what?
I am certainly biased by my lifetime final amp being a Class D. But I know that after 30+ years of development, Class D seems to be on a high plain. I know there are now many, many companies focusing on Class D and, maybe, a good handful already as good as it gets. My Class D amp is as smooth and beautifully musical as a great tube amp and as punchy and detailed as a great SS amp. I am satisfied and done with my search. A class D amp has effectively taken me off the amp merry-go-round. It’s about time after 50 years. And, for me, this Class D is a milestone. Will all other classes of amps fade away?

These companies that claim double wattage when impedence is halved don't give the actual 8ohm measurement, which is usually a lot higher wattage than their spec sheet has listed.Our class D amps do 100 watts into 8 ohms and 200 into four. There is probably a slight difference due to the output impedance that causes the 200 watt reading to be inaccurate but its too low to resolve. But in reality the amp doesn't clip at 100 watts- it does so at 125 into 8 ohms but into 4 ohms it clips at 250 watts. So while your comment is true in some cases its not true in all cases. While its true that the Wilsons have a low impedance in the bass (the Sophia and Sashas being the ones of their more recent lineup with which I'm most familiar) they really are reasonably efficient. When our MA-1 was hooked up to the Sashas (a friend of mine in town had them) the meters on the amp barely moved but there was plenty of volume. You have to take the drivability into account as well as the impedance. Our class D amps regard the Wilsons as a benign load.You keep mentioning Wilson’s as being hard to drive, where does this come from? |
Well..george has an MO of trying to cherry pick items to bolster his view. The Wilson speaker Sabrina X was not the Wilson in the conversation, he read in a rag that the X could give some amps issues and decides to bring it into the conversation but the X has nothing to do with the Wilsons i own and he accused of being hard to drive. Historically Wilson's have the reputation of being efficient and easy to drive BUT require the best in electronics to make them shine. Here are the Wilson's in question and george accused of being hard to drive. Page 77 has the specs. https://www.wilsonaudio.com/media/296/manual-alexandria-xlf.pdf |
There are specs, and then there are specs. A fuller understanding helps with this primer I came across:https://darko.audio/2021/06/kih-89-mind-the-gap/ All the best, Nonoise |
Well..george has an MO of trying to cherry pick items to bolster his view. You really need to get educated on this. Look at the paragraph direct above your last post, even he back down on the flagship Wilsons I mentioned that a Class-D can't drive to their best. And he cherry picked the ones that can, (Sophia, Sasha ect) because they have far easier loading that the Class-D won't be too taxed with🤦♂️ |
