| Class D vs Class AB - Looking for best used budget amplifier for Magnepan MG12 This is an interesting question. I have had a Marantz four channel Class D 450W amp on the four subs in my system for some years now. I often wonder if the sound would be better with a good quality 250 to 275 W Class AB amp. One of these days ... | |
| Why Power Cables Affect Sound @phomchick - Actually I doubt most cable companies could afford the R&D equipment to define their products improvements. I suspect most of these guys are small shops. | |
| The invention of measurements and perception @edstrelow - for that you will have to become a member of AES and read up on their publications. Once in while, they do have a good paper that correlates cabinet movement to tweeter movement. | |
| Which amp will cause a larger increase in electric bill? The only way to correctly answer your question is to find out the RMS current of the two amplifiers at idle and compare them. This is how you do it -> The wattage consumed for each will be the respective current times 120. Divide that pow... | |
| Which amp will cause a larger increase in electric bill? BTW, just to clarify, when I state Class A, I mean the entire amplifier is Class A. There are quite a number of amplifiers that have Class AB output stages with Class A driver and amplification stages. Those amps are still Class AB by IEEE defi... | |
| Which amp will cause a larger increase in electric bill? Actually, if an amp is pure Class A, it won't matter if it is push pull or not, assuming the power output is the same between the two. The reason is the maximum load current flows 100% of the time, so if the power output is the same, then the di... | |
| 2019 calendars "Not I", said the duck. But I am eager to see a source for some! | |
| Which amp will cause a larger increase in electric bill? In general, if it is solid state, I would not worry about power consumption or your electric bill. It doesn't matter if it is Class D or Class AB. Granted Class A amps do consume some power when it is on and idling but most Class A amplifiers ... | |
| Why Power Cables Affect Sound Actually, if one had a spectrum analyzer then one could see the improvement since it is easy to measure the power output with and without the new cord for a given piece of music. Once you have it hooked up, there is a LOT you can measure. Gran... | |
| Thinking of upgrading from pass labs x250 You probably need new tubes for those Citations. My CJ's start to sound constrained, stressed, and a bit weird when they want new tubes. I'd re-tube it and not look back, but I tend to be a tube guy on the midrange and upper frequencies and so... | |
| The invention of measurements and perception Erik - how do you figure 1 Ampere at 1 watt has a S/N of 90dB? There is no S/N correlation between Amperes and Watts. @jea48 - Actually, if one were to measure the linearity of the amplifier without loop feedback from min to max, there is a ve... | |
| Off grid digital music As a point of reference, my Bluesound notes states a one TB hard drive will hold about 20,000 CD's in FLAC format. I am using WAV files and I used about 4800 KB per CD. | |
| New $24,000 inter-connect Well, that is it - He needs the bucks for his attorneys. If he faked US made products, he is probably faking the sound quality of $24,000 interconnects. Even if he is not, I wouldn't buy from him. | |
| The invention of measurements and perception I studied a formula for jitter and how it relates to human perception some years back. I'd have to go look it up as I don't recall it exactly; the limiting number is related to the number of bits and the sample rate. Increasing the number of b... | |
| How To Utilize A Phono Preamp Board As Stand Alone kosst is correct, that is about all there is to it. Of course, you will need a chassis to put it in and all that goes with it. |
