| What value cap to bypass power supply cap? Hi Davehrab, thank you for your input. When I started this thread, I was confusing several things about bypassing. Here is what I've learned so far from helpful people like you and Kijanki. Please correct me if I'm wrong.1) The 1% bypass cap recom... | |
| What value cap to bypass power supply cap? Hi Kijanki, I think what you're talking about is putting a single cap at the input as an AC line filter. That is a great place for Mundorf Supreme. People have already tried this out and got good result:http://www.laventure.net/tourist/caps.htmHow... | |
| What value cap to bypass power supply cap? They're not for preamp or DAC. They're for monoblock amps. However, there are a total of 12 of these. Still not a lot by electrolytic standards, but they are huge cans, each about 7 x 5 inches and weighing around 4 to 5 lbs. According to the desig... | |
| Does OTL pre-amplifier exist? http://diyhifisupply.com/node/808 | |
| What value cap to bypass power supply cap? Amplifier's end means where the output transformer goes to ground, I think.I'm a little confused. "Increasing main capacitance will reduce impedance but also reduce self resonance point. It might be necessary step to combat ripple but does nothing... | |
| Preamps waste of money? Mrtennis, I have a DAC that has an output tube and a rectifier tube. I have been changing those tubes to change the "flavor" of my system. Having too many tubes in a system hasn't been a good thing IME. Too much heat, to many tube failures, too mu... | |
| What value cap to bypass power supply cap? Davehrab and Kijanki, I asked an experience electronics engineer who has written papers on bypass capacitors. His response to your statement:"As you can see from above, the self-resonant frequency will vary depending on the value of capacitor used... | |
| What value cap to bypass power supply cap? Kijanki, thanks for that info. However, all my power supply caps are film caps which according to the manufacturer have ESR and inductance which are a fraction of electrolytic. I know the ESR is 1 mOhm at 10 kHz, but I don't know the inductance. A... | |
| Preamps waste of money? But getting back to the subject of this thread, I'm not sure one can ever determine if his preamp is "neutral" unless he was at the recording session and all his other components in the chain are neutral. Essentially an impossibility for most of u... | |
| Preamps waste of money? Yes Kijanki, the Hyperions have one of the best midrange of any speaker I've heard, including electrostats and ribbon speakers. Their spiderless drivers are unique. They haven't folded yet. I might end up getting a pair of the 968s. | |
| What value cap to bypass power supply cap? Thanks! That was very helpful. | |
| Preamps waste of money? Kijanki, I used to own the Hyperion 938s, one of my favorites. I think I was the first to own a pair in the US having purchased them in 2004. I miss them, but to big for me. I would buy them again if my back wasn't so messed up. I have to say the ... | |
| Preamps waste of money? Last_lemming, I think your assumption less is more going the passive route is essentially correct, as long as you have equipment that are compatible and willing to make some sacrifices. I think I got lucky going this route. | |
| Preamps waste of money? Ralph, I have two digital sources and don't mind switching interconnects between the two, which I only do once in couple of months. Getting up from the chair to change volume and balance can be PITA, but I've gotten use to it. However, I have a so... | |
| Preamps waste of money? Devilboy, we have similar experience with these passives. I have to admit though in my system the stepped attenuator in the input of the amp was hands down better than the external passives. |
