| Class D Technology Cymbals, for instance, sound more "brassy" and less "splashy". To me it sounds more natural, but it might create false impression of limited extension. If the switching noise output filter is set at a higher cutoff so to make the amp look to be f... | |
| Class D Technology You aren’t sold on class d yet.Correct, and Technics are showing the way with the SE-R1, why strive for higher switching frequencies by deleloping their own components, if what we have off the shelf is "good enough". Technics knows and are doing s... | |
| Class D Technology Just a couple of quotes from other Stereophile measurements personel.I dislike measuring amplifiers with a class-D output stage. This is because such designs can throw out enough ultrasonic noise that you can never be quite sure that what you’re a... | |
| Class D Technology Here is just one of many that Stereophile tested, not using their test filter. It’s more than 1%. And this Class D had a linear power supply as well, most use smd now which creates even more other noises as well.http://www.stereophile.com/images/a... | |
| Class D Technology This small residue (about 1%) has no effect on the soundPut your ear to a wide bandwidth tweeter, you will hear it’s poluting artifacts. If not the filter effects is set very low to cut way down to 10khz or even less, creating all sorts of other p... | |
| Class D Technology If you want to be eco friendly, and be a little compromised at the moment, then sure get a ClassD. Or pay the bucks and get "maybe the new Technics SE-R1 Class D".http://www.technics.com/us/products/r1/se-r1.html#overview Cheers George | |
| Class D Technology I agree with George that switching frequency should be increased, since 50-60kHz bandwidth limitation introduces around 20deg phase shift at 20kHz (causing wrong harmonics summing), but I’m not even sure I can hear such nuances. There are many hig... | |
| Class D Technology georgelofi you are correct about switching frequency being teh key to even better Class D amps in the future.Have you listened to any good quality class D amps or are you judging solely on technical interpretation?Yes the new Belcanto 600 monobloc... | |
| Class D Technology The day will come when Class D will compete and very well be better than any linear amps tube,s/s, class A, AB or whatever, BUT!! Class D needs much higher switching frequency (needs to be at least 5 x higher) technology isn't there yet but in the... | |
| Looking for SACD player............ I think SACD is going the way of Betamax, excerpts I taken from the net. And rumors that Sony and Philips are now looking at DXD with is pcm."Esoteric has stopped OEM sales of SACD transport because Sony had stopped supply of the chip required to ... | |
| An all Parasound system - Good idea? The most important section of the Halo Integrated, is the poweramp section, this is directly taken from the A21 23 with slightly less rail voltage which is JC design. The rest of the integrated is a dac, phono stage, input switching and preamp gai... | |
| An all Parasound system - Good idea? I’m also a John Curl fan, and the Parrasound products he designed.Did you look at the Halo Intergrated (John Curl design) everything but the kitchen sink comes with this, even a DSD ESS Sabre Dac and a phono stage. Not quite the power of the A21. ... | |
| Rotel RHT-10 Tuner dansThis site is the bible for tuners that’s been going for years, I went with a few that they recommend and they were spot on with their reviews, but it looks like the Rotels didn’t rate.http://www.fmtunerinfo.com/ Cheers George | |
| How hard it is to replace the rca input on the shindo amplifier? How hard it is to replace the rca input on the shindo amplifier?Sorry but if you need to ask this and can’t solder, get someone (tech maybe) who know how to do it. It is a diy thing for someone who good with a soldering iron, sounds like your not ... | |
| Lightspeed Attenuator - Best Preamp Ever? Hi Soundwise, once again thanks for the praise you’ve given on the Lightspeed. As it stands with me there’s not much that can make it sound better. Others here may give things they’ve tried. 1:Some say battery power, the best power you can give to... |
