| Why would anyone want class AB amp when class A always sounds better ? In solid state amps only a handful and in tube only a handful also they are incredibly difficult to make and unreliable due to heat generation because of the 10 percent efficiency. So most of the makers if not all stopped making them. This stat... | |
| 845/211 tube amplifiers with kef reference 5? Am curious, how about push-pull 845 amplifiers in monoblock configuration? Eg 50w class A, each channel driven by 2 845 or 211 tubes? Would those be sufficient to drive the kef reference 5? If the amp uses feedback you'd probably be alright. The... | |
| Amplifier brand/designer with the most unique and consistent “house sound?” If you get rid of distortion and phase shift across all frequencies, will all amps sound the same? Should they? Even with different topologies, parts? No more house sounds?If their output impedance is also the same then at that point, yes, th... | |
| Amplifier brand/designer with the most unique and consistent “house sound?” That being said, are there other factors aside from harmonic and intermodular distortion that might account for different house sounds? Are there other factors which make different amps sound different, even with negligible distortion of any ki... | |
| High Pitched Frequency From Speakers, tried everything - - - Driving me crazy, help! Here are some things to try.Take the power conditioner out of the system and plug everything into the wall. If that does not fix it re-install the conditioner. If that didn't sort it, Next, unplug all the digital audio products from the wall. Digi... | |
| Amplifier brand/designer with the most unique and consistent “house sound?” So some like more 2nd harmonics and says that the amp sounds great, when others will even almost not want to turn it on to listening to the same amp, when it has according to measurements not and them to high distortion (as harmonics are).So Ho... | |
| 845/211 tube amplifiers with kef reference 5? it won't be a disaster like he's making out, he's got a bee in his bonnet, over something. 'Something' is misinformation. In case there is any question, I am a manufacturer of tube amplifiers that employ zero feedback. I know all too well that suc... | |
| Graham Phantom Mounting Bolts - Where to Get Them? Take one of the existing bolts to Ace Hardware or similar hardware store. Ace has a bolt sizing bit that allows you to sort out what thread it is- and if its metric or American thread.They may well have something like that in stock! But if they do... | |
| The Lifespan of an LP? I'm thinking that the return rate of CDs is probably lower than that of LPs.Yes- as far as new media is concerned, CDs do just fine. It's not clear from the line above exactly what the study concluded about CD lifespan, but if they meant that CDs... | |
| 845/211 tube amplifiers with kef reference 5? That’s just what sets do, look at ANY SET into the Stereophile simulated speaker load frequency response graph, most sets act like tone controls. Sheesh! The Stereophile simulated speaker load ignores the fact that SETs do not function a voltage... | |
| Cons of using main XLR/Balanced outs for subwoofer? @zdw11 @imhififan has it right. Nice setup! | |
| Best cost no object tube phono I'd probably have in mind to use EMT OFD 15, 25, 65 & JSD with FM Acoustics...to easily take advantage of the EQ curves, as I have many 78s. @mcmprov Do you have cartridges with 78rpm styli as well? The larger stylus makes less noise in the ... | |
| Cons of using main XLR/Balanced outs for subwoofer? @zdw11 Unless the preamp has entirely separate circuitry driving the RCA and XLR outputs, when driving both you will have a lower impedance load on one of the XLR signal pins (pin 2 or 3) than you do on the other. The preamp may make less voltage... | |
| The Lifespan of an LP? The CD is about to turn 40 next year and so far there have been very few reports of CDs failing. ?? I've had a few of them fail for no good reason. I think everyone has- heck, I've bought a couple brand new and found them to be unplayable. If so... | |
| Cons of using main XLR/Balanced outs for subwoofer? Is there any harm in using the main XLR output to send signal to the subwoofers, and using the 1, or 2 RCA output to send signal to the main drivers?Yes. You'll unbalance the signal going to your main amps.The solution is to use a set of special... |
