| What does ‘balance preamp’ mean? No, a real balanced circuit is one where the positive (+), the negative (-) have distinct circuits, and negative is distinct from earth.So there is a higher manufacturing cost. There is also noise cancellation -- i.e. any noise common in both c... | |
| Preamp SS to match class D amp Going through forums people ask advices only on tube pre amp to combine class D amp probably for the fact of the colorations of tube and some sterile class d amp they own.Tube preamps are not used to add colorations. They are used to avoid them ... | |
| What is Floyd Toole saying about extra amplifier power and headroom? Perhaps what @mapman was saying about increasing current flow could help this situation. I'll have to look into it. Thanks for your thoughts! The thing is, when you have thermal compression there is a tendency to turn up the volume/throw more pow... | |
| What is Floyd Toole saying about extra amplifier power and headroom? If you're talking Floyd Toole, then expect to hear about a Distributed Bass Array too... but since that is off topic that's all I'm going to say about it. But that isn't what the problem is with excess power. In a traditional push-pull solid state... | |
| Logical cartridge upgrade for a long time Shure M44-7 user The trick here is knowing what the original tape actually sounded like. If there are tonal aberrations in the playback it will certainly affect how you hear things. If that's the only way you've ever heard a certain recording when you hear how it ... | |
| Never Owned a Tube Amp and Want Advice ^^Good- that's how its supposed to work :)The Audio Technica cartridge could be part of my problem as I was not knowledgeable about tone arm and cartridge compatibility. I would have to admit the AT cartridge is a bad match for the light weight ... | |
| High end Class D amps? By the way, if you are using a toroidal transformer and you use metal plates or bolts to secure it to the chassis....you are closing down the sound. You want your toroidal transformer off the chassis on a piece of wood an mounted using tie wrap... | |
| Tube Amp lower power vs higher power and cruising volume Isn’t the Berning amp similar in that neither design has the traditional audio output transformer? In that regard, yes, since the output transformer used in the Berning is an air-core device. | |
| Logical cartridge upgrade for a long time Shure M44-7 user One reason the M44 is so bright is that the tonearm cable has a certain capacitance, and this is interacting with the rather high inductance of this cartridge to produce a high frequency peak that is quite audible! I doubt any cartridge with 5mV w... | |
| 2nd Order Filters Cause 180 Phase Shift ^^ This. The phase will be correct in the passband. | |
| Stahl-tek Vekian - help please! Contact Purist Audio Design in Clute, Texas. They did most of the distribution and know where to contact the designer, who is quite brilliant. | |
| Control volume with DAC or Preamp? And that we'll never know, as it is the graph shows roll off starting at 100hz already and that's with a 100k!!! loading, Stereophile usually also give a 600ohm loading, strangely omitted this time.Uh, George, you missed my point entirely. | |
| Tube Amp lower power vs higher power and cruising volume The David Berning stuff is wonderful. I am not sure if these designs are as adverse to lower impedance speakers as other OTL designs seem.The Berning ZOTL amps are not OTLs by any stretch (read the patent), although a brilliant design nontheless.... | |
| Best modern 6550 tube for ARC per-amp In any single-ended product the quality of the regulator is certainly quite audible! And while the signal does not go through it, the regulator has to have good linearity just like any power amplifier- and that is exactly what it is. So you want t... | |
| High end Class D amps? Problems with any amps shouldn’t be fixed by using even more feedback as a fix, it’s a added by the best designers to clean thing up a little and usually just local not global in an already well designed amp. All the greatest amp designers say it.... |
