| apt holman problems That preamp is old enough that I would replace the filter capacitors in the power supply before anything else! Electrolytic capacitors (which are used in the power supply) really are only good for about 20-25 years- after that probably about 50% o... | |
| Need advice replacing my preamp FWIW most high end audio preamps, even though actually balanced, don't support the balanced standard, known as AES48. AES48 prevents ground loops from making buzz, and prevents interconnect cables from having artifact (if you've ever heard differe... | |
| Matching subwoofer Almost any sub that has controllable crossover points and volume will do.You'll want to set the sub crossover frequency to about 65Hz so it will have no output above 80Hz. In this way it will not attract attention to itself and you can thus place ... | |
| High end Class D amps? Ha! Photos or it didn't happen. If he wants a classy Italian early 70s motorbike that he can actually ride without fear of it stranding him, maybe a Laverda instead of a Ducati. A Laverda from that period is far more reliable, far more likely to s... | |
| High end Class D amps? I’ll state once again as yet NO!! Class-D (and that also goes for my choice Class-D Technics SE-R1) will perform as good into a pair of Wilson Alexia and such, with their EPDR bass loadings like a hi current Gryphon Antillion etc etc can.Just l... | |
| High end Class D amps? Well this is an excellent example of how George has no idea what he's talking about. Sheesh.George, perhaps you could come up with some evidence of your preposterous claim?? You know what they say- photos or it didn't happen. | |
| High end Class D amps? Combined, these two give’s you what’s called EPDR, (Equivalent Peak Dissipation Resistance) and that can give the amp a very nasty load impedance to look at. Good big current bi-polar amps don’t mind seeing this.Class-D tends to quickly drop of... | |
| Purifi Class D: Junk? Can you illuminate me on what types of differences, among equally rated and types of fuses you have encountered? How precise did the DVM have to be for you to measure it, and what qualities do you look for? The voltage drop across the fuse vari... | |
| Purifi Class D: Junk? Almost all tube manufacturers....they pick caps, etc. by ear....and they don't measure any different.This statement is false- they do indeed measure differently (whether some companies bother to measure the differences is a different matter). We u... | |
| The problem with Magicos Jeez.Just go up the original post, and report it. The Report button is in the lower right side of any post on audiogon. If we all do this, there's a good chance this thread will go away. | |
| Is there a Solid State amp that can satisfy a SET guy? Headphones bring an addition bit of clarity that's hard to get with loudspeakers. Current drive is advantageous for headphones, but impractical for loudspeakers. | |
| What is Floyd Toole saying about extra amplifier power and headroom? I have come to believe, with limited data that the issue is not the amplifier’s power rating but how consistently it performs across the audio band, and this is a place where the math doesn’t quite live up to the audible effects. The problem is... | |
| preamp-how important is separate enclosure for pwr supply? The power supply is always critical!We have five power transformers in the power supply of our MP-1. As a preamp in a single box, the box would have been heavy and enormous. Even with the use of toroids we've seen radiated magnetic fields which co... | |
| Phono Preamp suggestions $2000 (pre-rabbit hole tire kicking edition) The problem you are up against with a phono section is that the cartridge and tonearm cable have an electrical resonance that can really mess with the front end of a phono section. The resonance can easily overload the input section of the preamp,... | |
| Phono Preamp suggestions $2000 (pre-rabbit hole tire kicking edition) I agree about 'slam' but seriously, 'dynamics' usually means distortion. This is because the ear uses the higher ordered harmonics in order to sense how loud a sound is. When the electronics is adding higher ordered harmonics even in very small am... |
