| How To Do You Measure the Quality of Your AC Power? I think some mistake noise in the system to a ground loop.Let me preface with "not trying to be argumentative" - you both seem to know what you're doing and have things under control. But let's nto tell others that up is down or up isn't really hi... | |
| How To Do You Measure the Quality of Your AC Power? I'm simply saying that i have used this in many systems to remove a ground loop hum. Sometimes you have the same reference on two outlets, sometimes you don't. But the simple fact that they are not the same places violates the principle of star ... | |
| How To Do You Measure the Quality of Your AC Power? @jea48 :Careful. You're talking mostly about things that impact the power company and/or maximum utilization of your step down trans. Nice, but not huge sonic issues. The reason that many (including me) say that equipment ought to be on one leg,... | |
| Electrolytic capacitor replacement I ought to have added, what i define as "superior" are the characteristics that affect sound quality, specifically both frequency and phase linearity. They are dissipation factor and dialectic absorption. Both are often on the datasheet. ’Lyics ra... | |
| Electrolytic capacitor replacement Elegant would be more eloquent. Ditch the board. Hardwire direct. That's what I did. See the last couple pics on my system page.:-) correct on both. But wait, there's more.I often drill holes in the existing PCB that match the leads, and use copp... | |
| Replacing selector knob terminology: its the switch contacts that are flaky. The know is the handle and is decorative.The fix is likely electronics parts cleaner followed by a lubricant. but we do not know, you need to take it apart and also look for mechanical damage.I... | |
| How To Do You Measure the Quality of Your AC Power? Let's disambiguate. (is that word?)Typically we worry about Noise. MC went on (correcly) on noise. The only solutions involve various type sof filtering, including normal filters and (better) isolation transformers. Bear in mind that YOU are like... | |
| How important is the pre-amp? ... should have continued. But a DAC **can** have a solid, low-output impedance. That doesn't mean they all do, or that they are all good ( the vast majority of chip opamps, sigh). So again, there is no right answer, no simple answer. You need ... | |
| How important is the pre-amp? a key word that seems to have been overlooked. IMPEDANCE.Actually both MillerCarbon and I went into it. I did very specifically. And basically, yes, a hgih output Z and low input Z is a bad combination. Plus some (very long) cables may have som... | |
| How important is the pre-amp? If I have just a power amp hooked up I know you need one.Then it comes to tube or soild state.I have tried both and use many different brands.I still like switching things around.The point of this thread is ... no you don;t. But is it beneficial... | |
| Any Vienna acoustics love out there? Anyone even still using them? actually then the mahlers are a tougher load 89 or 90 dB i believe.thanksa 91 dB speaker is not that difficult. the 4 ohms means it must be a real power amp, btu these are $25k speakers after all. | |
| How important is the pre-amp? It’s about the size of the signal.The signals from sources are very small and delicate...Truer than most realize - gain from low output MC to line is about 1500X.But i believe this thread would benefit form a very clear distinction between a **pho... | |
| Any Vienna acoustics love out there? Anyone even still using them? How much more juice do the Musics need that their predecessor the Mahlers? While they can use it, I've driven mine with my prototype integrated amp that has less than 35 wpc (but unconditionally stable and very high peak current). In normal use ... | |
| How important is the pre-amp? Noble is a good place to start…..???? for what? | |
| How important is the pre-amp? For just 1 added component, saya CD player, we only need 1 outSo you are saying a simple DIY 44 step attenuator + some resistiors, = beats high priced pres?Yes??Well....sorta. Mine is intended to go into volume production in products so it s a bit... |
