Class D = Trash?
I would like to see one and compare bit by bit to verify that they are the same,I would like to know, what a 1 off price is from EveryChina Sanway site can’t be too much knowing these types of outlets. http://discosoundequipment.sell.everychina.com/p-99120690-professional-audio-disco-sound-equipment-class-d-modules-for-active-speakers.html Or even the maybe tweaked version from Denmark http://www.pascal-audio.com/amplifier-modules.html Cheers George |
I see what appears to be contradictory statements about break in. But you are all basically correct based on my experience. Teo says if something sounds bad, don't keep it. Well good, but when you find a product that does sound good, what do you do?... Break it in to get the most out of the component. I agree with Geoff, that very low power, like in interconnects (2 to 6 volts) is not enough. A burn in devise is needed. Don't get too wild here like I've done in the past. Be safe and practical. Finally, an important factor is time, mentioned by the person taking notes over several months. Also the FM noise is great for burning in tubes. It only takes a couple of hours of the noise along with some music for tubes in my experience. So go with a burn in devise, a burn in CD, and music. This will drastically reduce the time needed for full burn in and stabilizing the sound. Regarding Class D amps: I have heard very good ones, and some that sound like something is wrong somewhere. You just need to listen to a few of them to know. |
I just read this thread from the top and, as one who has only briefly heard a couple of Class D amps in hifi shops, one a Rotel, the other a Bel Canto, the sound wasn't anything remarkable or outstanding. But the comment I want to make here is that, if I were considering which way to go if I were building a system from the ground up, and I did my due diligence by reading all of the above, the content of this thread would give me pause and would likely steer me away from considering Class D anything. I'm not reading consistent sonic and utility praise for the format. Why is that? |
Hi @stevecham, for a different perspective on class D amp, you might want to read the following thread: https://forum.audiogon.com/discussions/class-d-is-just-dandy There is a rapidly growing number of music lovers are adopting class D amplification and are loving it. Having said that, not all class D amps are able to make wonderful music... But isn't this true of all amplifier topologies?! Regards, G.

stevecham, You asked: "I'm not reading consistent sonic and utility praise for the format. Why is that?" I can only speak for myself but I think many class D users will probably agree with my answer to your question. I don't specifically praise the sonics, or mention any of the usual terms used to describe the sonic characteristics of amplifiers in the past, in any of my posts on this thread or whenever I've attempted to convey the overall sound of my several class D amps for a very simple reason that is very obvious to anyone listening to a good class D amp in their system: Good class D amps are extremely neutral, have no consistent sonic signature that is imparted onto the music and therefore there are no sonic qualities to criticize or praise. Criticizing or praising the sounds one hears through a good class D amp is essentially just an evaluation of the music since there is nothing discernible that is added or subtracted from the original signal. In my experience, good class D amps behave just as many have consistently described how an ideal amp should behave; like 'a straight wire with gain'. As to consistent utility praise for the format, I think you need to reread this thread and pay closer attention because the practical advantages of class D amps when compared to traditional amps has been well covered in this thread. I'll summarize the utility advantages of class D amps have over traditional amps, however, to save you the time: Class D amps are much lighter, usually much smaller, are significantly more efficient, produce much less heat and generally are less expensive than traditional ss and tube amps. I also believe class D amps will be proven to cost less to maintain and operate while determined to be more reliable than traditional amps as data is accumulated and analyzed. Tim R |
