| 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.... | |
| High end Class D amps? How many class D do I have to listen to? Is there a The class D which disproves the "myth"? Did I just happen to miss the good ones?Here are some tips. The first thing is avoid amps using switch mode power supplies. The reason for this isn't that... | |
| Control volume with DAC or Preamp? If you look at the graph George posted, be sure to observe the vertical scale as it is in fractions of a dB. -0.8dB down is not bad for a transformer coupled unit. However it should be noted that output transformers need to be loaded properly for ... | |
| Control volume with DAC or Preamp? I’m not sure that one could accurately describe the OP’s direct from DAC to amp application as “passive”?@unsound Check my original post in this thread. | |
| Control volume with DAC or Preamp? Ralph is product (his active preamp) protection mode, omitting the reason behind a "why" the "rare" times a passive "may not" be the least coloured, least distorted, and best dynamicallyThe reason passive controls tend to sound more colored is t... | |
| High end Class D amps? George is correct. Lack of switching bandwidth is the problem. I know Bruno Putzeys claimed differently in an old interview, but he's mostly a self-promotor so no one should take what he says as gospel truth.For the record, Bruno Putzeys is the ... |
