| Who tried Class D only to return to S/S or Tube Ait, I understand that choke helps storing and releasing energy, but it won't affect charging of capacitors that has to happen in very short time. | |
| Who tried Class D only to return to S/S or Tube Ait, Perhaps I'm missing something. Imagine rectifier charging capacitors to 50V with 5mV ripple present. http://i.stack.imgur.com/BLGnf.gifCapacitors are charged ONLY during voltage increase on capacitor. This period for 5mV ripple (1% of 50V) ... | |
| Who tried Class D only to return to S/S or Tube Ait, Choke at the input as well as choke and big capacitor in my Furman Power Factor correcting conditioner serve as filter. Charging Linear PS capacitors is still done in narrow spikes of high amplitude - no escape from that. Current is switched... | |
| Who tried Class D only to return to S/S or Tube I’m a little puzzled by all this "switching" talk. My class D amp has 60kHz bandwidth while tweeters are almost completely quiet with my ear next to them (200W amp). I’ve read the same in many reviews of different class D amps. It was much wo... | |
| New preamp, loss of low freq.? Many power amps use servo on DC (very low frequency NFB), that might become unstable with low input frequencies. For that reason amplifier's low frequency is often limited (in my amp to 5Hz). | |
| Who tried Class D only to return to S/S or Tube "Once the technology is there and they put that switching frequency way up higher, then and only then will they be able to filter the s**t out of it away from the audio band and leave a nice clean square wave, and only then will Class D have becom... | |
| Why a headphone amp Bigsam2, I have already Benchmark DAC1 with good headphone amp built in, but I bought separate headphone amp for convenience. DAC1 is across the room and requires long cable that is easy to trip over. In addition switching off main amp would requi... | |
| Speaker Cable connection: Jumpers Runnin, I have separate posts for tweeter, midrange and woofers. I use Audioquest jumpers between tweeter and mids posts. I run shotgun cable from amplifier to woofer and tweeter/mid (cable connected to tweeter side). These jumpers are made of hig... | |
| Who tried Class D only to return to S/S or Tube My Rowland 102 sounded the best after about 400 hours. Class D amps are very revealing and often don't work well with some "bright" components. I cannot say if class D works better when powered for a while since it is always on in my system. It do... | |
| why do people feel the need to buy expensive cable Calvinj, replacing AQ Indigo with Acoustic Zen Satori brought, in addition to more refined sound, fuller lower midrange I was looking for with my class D amp (try to explain this in terms of R,L,C). Cello now sounds real, male voices have "chestin... | |
| why do people feel the need to buy expensive cable Calvinj +1I accept it. I also know that some people have much better hearing than mine. | |
| The Hifi Trajectory Of Class D Amplifiers Bombaywalla, comparison film vs. digital SLR is very unfortunate here, since class D is purely analog with unlimited resolution.Still, you can take equivalent quality pictures using medium frame size film camera for much less money than digital, b... | |

| The Hifi Trajectory Of Class D Amplifiers Rushton, I don't question anybody's qualifications but rather particular example. I'm pretty sure we can find 500W tube amp that doesn't keep up with 400W class D bass amp, but again it wouldn't be relevant to the issue we discuss (class D sound i... | |
| We seem to highly regard DEMO over anything else. I bought 6 month old demo speakers for 60% of the price. They have full factory warranty and sound wonderful. |
