| Class D is just Dandy! One thing I'd like to see for the nCore modules which I can't find is output phase angle. If anyone can point me to a doc which has this I would appreciate it. I notice that the ICEPower units do have some phase shift involved. It is minor compare... | |
| Class D is just Dandy! @kdude66 Thanks and welcome! :) Erik | |
| Suggestions for active crossover setup please. Hi @bob_reynolds I'd be happy to. I have been using satellite/subwoofer systems since Miller & Kriesel claims to have introduced the concept with the S-1B monitors and an active sub. After a lot of experimentation, and using full-range speaker... | |
| Suggestions for active crossover setup please. This is a really good idea, most flexible, and has the most problems with room integration. IT is a lot easier to integrate a bandwidth limited speaker (45 Hz and up) than a sub + satellites into a room. The lower you go, the more dragons you find... | |
| Class D is just Dandy! Hi @guidocorona Thanks for the suggestion. I feel bad asking for a loaner pair with no intention of buying. :) To everyone else, it is really the contributors on this thread, even those i don't agree with, who keep it interesting and welcoming. :)... | |
| Speaker recommendation for married couple Where are you geographically? E | |
| Class D is just Dandy! Hi @guidocorona I wish I had a way to listen to an nCore pair without spending money. :) I would be better able to discuss the sound quality honestly. What I can repeat, is that compared to Parasound Halo A23's which are heavily class A biased, I ... | |
| Class D is just Dandy! Hi Tim,I just tested it. It actually is a PDF download, so check your download files. :) Best,E | |
| Class D is just Dandy! Following on, at 200 Hz the output impedance is 10x better with nCore, but the absolute figures are tiny. The difference in output between a high and low impedance speaker is less than 0.01 dB.Most "normal" speakers get very difficult to drive in ... | |
| Class D is just Dandy! So, let’s get into some meaningful spec-manship. Let’s compare the frequency response, and output impedance (8 / output impedance = damping factor) of ICEPower and nCore to see about what could matter with different speakers. Here are the source d... | |
| Class D is just Dandy! I'm just saying that I am open to the possibility that different Class D amps, like their linear counterparts, may sound different on different speakers. But if this IS true, I won't attribute it to Class D vs. linear.I believe nCore's do have exc... | |
| Class D is just Dandy! Hi @guidocorona The general principles that a higher switching frequency with better transistors yields lower distortion and higher efficiency is not really in question. I question the audibility of anything measurably better than the current stat... | |
| Surge protection for amps? @westom shows up again and talks bs about numbers and circuits he doesn’t understand. I think this time he’s switching current and volts. MOV’s / Shunt type surge protectors are most cost effective at the panels. Noise dampening can also do a lot ... | |
| Class D is just Dandy! Also, the meters on the Technics SE-R1 are super cool. Wish I could buy the casework alone. | |
| Class D is just Dandy! At $17k a pair? No. No thank you. I’ve heard current linear amps that were about that expensive and I wouldn’t switch to them either. To me the idea that we need super technology to finally fix the Class D problem just wont’ fly. Blame my tin ears... |
