| Atma-Sphere Class D… Amazing I’m curious why the Atmasphere Cl D amps are so low powered, compared to many others. Most D’s seem to claim fairly high power. I guess the switching power supplies are not so constrained by size and weight limitations. I had a D-Sonic, based ... | |
| Atma-Sphere Class D… Amazing I agree with that whenever SQ can be affected, but making thick chasis just to protect the amp during the shipping seems to me unreasonable - just pack it well! We've always packed our equipment well to survive FedEx/UPS treatment. But experi... | |
| Atma-Sphere Class D… Amazing Indeed, those marketing Hypex, Purifi, and several other class d amps using the modules of others can "tune" the sound through the input buffer op amp choices @kuribo If they can ’tune’ the sound just by changing opamps they are either using re... | |
| Atma-Sphere Class D… Amazing @kuribo The cost has to do with how the equipment is marketed. We use a dealer network and have worldwide distribution. That requires that we have it priced accordingly. Dealers can be quite valuable because they can provide support!! FWIW if we w... | |
| Atma-Sphere Class D… Amazing So yes, Class D is more accurately referred to as a "switching amplifier" rather than a "digital amplifier" but things get blurred when binary quantization is involved as binary quantization is at the heart of digital too. @fsonicsmith The on ... | |
| Atma-Sphere Class D… Amazing And then we come to digital amps as a category. They are insanely cheap to manufacture as has been pointed out elsewhere in this thread. To my mind, a digital amp is a switching power supply built to drive loudspeakers. If there is a simpler way ... | |
| Atma-Sphere Class D… Amazing @wolf_garcia The smaller guitar amps will hang around for a while because they are low enough power that its practical to overdrive them. But the bigger stuff like 100 Watt Marshals are likely threatened, if someone can put a class D amp out there... | |
| Atma-Sphere Class D… Amazing While these rules of thumb are helpful perhaps to people such as yourself designing amplifiers aimed at as broad a segment of the market as possible, they are not "laws" or universally applicable "truths" like the law of conservation of energy or... | |
| Atma-Sphere Class D… Amazing Would you mind reiterating your past comment of how Class D (yours and perhaps others) have finally made the leap to outperform tubes (yours and others)? I find the class D to be more transparent in my system compared to my tube amps; less colo... | |
| What is the “World’s Best Cartridge”? Some of my European Classical albums from the 70s and 80's are fabulously quiet and are great recordings. I can not imaging new releases being any better. QRP (Acoustic Sounds) has succeeding in making LP surfaces that are about 10-15 dB quiete... | |
| 15 ohm speakers yea or nay? @yogiboy These days sensitivity (2.83V/1 meter) is how speakers are measured. There was a time when efficiency (1 Watt/1 meter) was the spec instead- back when tubes were King. 2.83 Volts into 8 Ohms is 1 Watt. That is why the seemingly arbitrary... | |
| I think I just smoked my Amp I replaced the fuse with an mdq-8, as indicated by the schematic. Still curious about the mda-8 fuse I pulled out of the unit, wondering if that being the wrong fuse had anything to do with the failure. @rfnoise Of course it did- it was the fai... | |
| Atma-Sphere Class D… Amazing Testing has indicated correlations between certain distortion spectra and "averaged" or group perceptions but there has been no perfect correlation established between measurements and human response on an individual basis because at the end of t... | |
| Atma-Sphere Class D… Amazing The trick here is understanding that the measurements, if the correct ones are actually made, affect what you hear in a very direct way. There used to be a disconnect in this regard because we simply didn't have the technology to show things like ... | |
| Atma-Sphere Class D… Amazing Unfortunately they are a bit too expensive for me, will there be a cheaper stereo version ? I sure hope so! I want maybe 50W/Channel stereo integrated. |
