| **Smoking integrated tube amp, advice needed: There is no damage to the shipping box, but unfortunately the seller didn’t reply to my request to remove and individually package the tubes prior to posting, so there’s every possibility that something may have been damaged in transit. @fugazi... | |
| Accuphase or Leben for heavy metal @apanhc Just so you know, there's no way to design an amplifier (or loudspeaker) for a certain genre of music. As long as you have the bandwidth and power to reproduce the signal at a lifelike level you're golden, as long as the electronics and sp... | |
| Higher Impedance MC Carts on Transimpedance Stages? @hagtech +1 Transimpedance works nicely if you have a nice low output. Not so well as the impedance of the cartridge goes up. In a transimpedance circuit, the cartridge replaces the input resistor of an opamp. The gain of an opamp circuit is the... | |
| Could Class D really be that good? Did you not read what I said? I said the amps will all measure the same.....this is absolutely true. While it is true that when changing parts the distortion changes....because all noise and veils are distortion. However, you CANNOT measure a ... | |
| **Smoking integrated tube amp, advice needed: @fugazikid1991 Sounds like the amp was damaged prior to your placing it in your system. Was the shipping box damaged? | |
| Cool running, low powered power amp @dtorc FWIW, we make a 5-Watt/channel class A tube amplifier that can sit on a sheet of notebook paper with room left over. I designed it for my bedroom system. BTW, something to keep in mind about SETs: if they have no feedback (and most don't),... | |
| Cool running, low powered power amp Class A is always going to run warm. There's no such thing as a 'cooler running Class A.' They would only be cooler by being lower power. There are class D amps that sound every bit as good as the best class A tube amps now so no need to deal wit... | |
| Could Class D really be that good? Yes, the amount of distortion and its spectrum has some correlation to sound. However, it is not the major or only thing that makes and amp SOUND the way it does. You can give me 3 pairs of Atmasphere amps and I will change some of the parts in o... | |
| My new review for The Absolute Sound comparing AGD GAN amps with BHK300’s @wolfie62 Output capacitance of a class D isn't a thing as you say, but output capacitance of the output devices is. Its nice to have that low for better switching. | |
| Could Class D really be that good? Most agree that the 2nd harmonic is innocuous to the human ear; the real issue here is are the 2nd and 3rd able to mask higher ordered harmonics. I've heard the argument before that if they are 90dB down you aren't going to here them, which I thin... | |
| MC-MM-MI CARTRIDGES . DO YOU KNOW WHICH HAS BETTER QUALITY PERFORMANCE? REALLY? The best explanation came from J. Peter Moncreiff (IIRC) who said that moving magnet/moving iron cartirdges impart a fuzziness to the instruments that is missing from a moving coil. The effect is subtle, but noticeable as an overall cleaner, mor... | |
| Could Class D really be that good? @lanx0003 The differences you hear in the sound of amps, if FR isn't an issue (which most of the time it isn't) is the difference in distortion of whatever amps are being compared. There are three things that define those differences. What freque... | |
| Could Class D really be that good? @lanx0003 I was looking at a different article. In this one we see a dominant 3rd (my memory playing up; I still seem to recall seeing a dominant 2nd) which is treated by the ear in much the same way as the second and is the only odd ordered har... | |
| My new review for The Absolute Sound comparing AGD GAN amps with BHK300’s If I use a switching semiconductor to switch at 2 mHz, are you going to call that device an “audio output” device??? Thats what these GaN devices are, and that’s how they’re used here! That’s how Class D amps work! These devices are no more “au... | |
| Could Class D really be that good? @lanx0003 Sure! Just look at the harmonic spectra of the Purifi module. You'll see a dominant second. Keep in mind that in a class D amp, the things that cause traditional solid state amps to sound harsh and bright might not exist. For example, i... |
