| 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. | |
| Atma-Sphere Class D… Amazing The thousands of audiophiles all over the world that listen to wires, fuses, jacks, etc......are LIVING PROOF that these things are real. What proof (listening tests) do you have that what they all say is wrong? Please share. Ok. In our zero fe... | |
| Transients hurting my ears on hifi solid state amps To me, modern higher end solid state amplifiers tend have too much slam or too sharp transients and that ends up hurting my ears even at 60db levels. Even listening to mellow jazz, the piano notes are just uncomfortable to listen to because of th... | |
| What is the “World’s Best Cartridge”? @ghdprentice I agree on all counts. I would prefer to not have all that space taken up by so many LPs, but OTOH I'm also a bit uncomfortable with having all my music on the cloud, since this means a server farm (which can take as much power as a s... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? @lewm This has to be corrected though. As I pointed out earlier, if the chassis isn't directly grounded it will act as an antenna rather than a shield. Back in the 70's and 80's in South Dakota where TV stations were rare, farmers used to park an... | |
| Atma-Sphere Class D… Amazing So, one thing that would make it sound more open sounding is to remove the steel plate over the transformer and removed the steel bolt. I’ll let you in on a secret. Use Non-magnetic stainless bolts and then you don’t have to go thru all that. A... |
