Class D, as soon as your warranty runs out have fun getting somebody to fix it if & when it goes down, with all the surface mount components in new digital amps most techs won't touch them including me, (not wanting to use a magnifying glass or microscope) it becomes garbage or parts. I have one I use for a sub for my TV, but that's it. Very light weight power amps which is great, other than that no thanks, Ill stick to to things I can repair myself.
The Future of Audio Amplification
I have recently paired an Audio Research DS225 Class D amplifier with an Audio Research tube preamplifier (SP8 mkii). I cannot believe how wonderful and lifelike my music sounds. The DS225 replaced an Audio Research SD135 Class AB amplifier. Perhaps the SD135 is just not as good as some of the better quality amps that are out there, but it got me thinking that amazingly wonderful sonance can be achieved with a tubed pre and Class D amp. I have a hunch that as more people experience this combination, it will likely catch on and become the future path of many, if not most audiophile systems. It is interesting that Audio Research has been at the forefront of this development.

With these, you can: https://www.amazon.com/Magnifier-SOONHUA-Head-Mounted-Magnifying-Replaceable/dp/B0742CJJM9 Surface mount can easily be done if you have the right tools. Most class D amp use dedicated chips; for example a single chip that includes encoding scheme, high and low side level shifting, driver circuits and dead time circuits. The outputs don't see the same stresses as conventional power transistors because the heating cycles are less extreme and it is heating cycles that ultimately damage power transistors (although conventional devices can handle well over a million heating cycles so its probably moot). But most class D amps in high end use some sort of module so if one is needing repair, you just replace the module which is much easier than servicing the unit at the board level. |

Speaking for myself, I love it when someone starts a thread with the title “the future of...” . Whatever comes next is whatever they’ll be peddling, singing the praises of etc. Class D, why are the fans of class d so defensive? we get it. You like class D. But stop behaving like a cult and pushing your views as people skirt by, mumbling about having given at the office. Yeesh. |
