| Lightspeed Attenuator - Best Preamp Ever? 05-19-14: ErwannThe only limitations I can think of, have nothing to do with the sound: leaving the volume control half-way to extend the life of the optoisolators took some getting used to, and indeed the lowest setting lets will let some minimal... | |
| oppo's volume control If you have any technical knowledge at all Running, you would know that a limited lf frequency of 5hz is only done by having capacitors coupling, in the signal path or in the feedback network of an active preamp. And you are in a state of confusio... | |
| oppo's volume control No assumptions Runnin, no need to get defensive any tech will tell you, just look at the factory specs on your P7, the FR (frequency response) is curtailed at at 5hz!! this means it's capacitor coupled within it's circuit, for if it was not capaci... | |
| oppo's volume control If you looked 7 post up I don't have to phone them, I got the answer for you already from the head of technical at Oppo above. Oppo's email to me, the reason is because of "bit striping" at volumes below 80, that's why it's not recommended, not be... | |
| oppo's volume control Like I said in the post above about yours Runnin, there is a problem with your Oppo they/it should not do this, it is a design fault or component acting up, adding a preamp that has no doubt some coupling capacitor/s in the signal path is stopping... | |
| oppo's volume control 05-14-14: Doak@Georgelofi: Fighting a losing battle. It's OK to be wrong. Not at all Doak, it's ok if some can't see the forest for the trees. Direct is the best transparency possible, runnin obviously has problems coming out of his source doing t... | |
| What direction should Hi Fi tune fuse be installed I'll post once and once only.Those that belive AC mains fuses are directional, can easily prove their point, by getting someone of high regard like Nelson Pass or John Curl to back them up on this.Here are their PM's so you can ask them to respond... | |
| oppo's volume control You have another problem Runnin if as it should not happen. A reply email I recieved from the the head of technical department of Oppo USA regarding direct connection to poweramps."The BDP-103 players will lose bits if you lower the audio below 80... | |
| oppo's volume control From just a couple of reviews of the Oppo going direct into poweramps and using it's own volume control, instead of having a preamp in the system Excerpts from Hometheater"Using the BDP-105 as a fully-functioning preamp by disconnecting my referen... | |
| oppo's volume control 05-11-14: Kr4The "official" word has been that none of the 10X series are recommended for use as a preamp although Oppo recognizes that many will want to do it.I find this odd, but maybe it's for other reasons than sound, I will find out. Kr4 can ... | |
| oppo's volume control If the output impedance of the Oppo is low enough to drive the input of the poweramp (which it is, as all Oppos I know are less than 200ohms output impedance even less than 100ohms).If the voltage output of the Oppo is high enough, to give more th... | |
| oppo's volume control I don't know which Oppo you have, but direct to the poweramp/s will be the most transparent/dynamic sound you will get, if the Oppo you have has it's analogue volume control before it's output buffer. Or if it has a digital domain volume control t... | |
| Lightspeed Attenuator - Best Preamp Ever? These are the Ebay 12vdc rechargeable Li-Ion batteries (and similar) that I have been recommending, they have (usually) 2.1mm plugs and centre positive. which is right for the Lightspeed Attenuator, just check to make sure.All users say they prefe... | |
| Which sounds better? Parasound Halo JC1 vs The John Curl designed JC1's will drive anything you can throw at them, even the impossible to drive at their best "Wilson Alexia's". I think they are the best value in big amps.As you can see below, the watts just keep increasing with lowering im... | |
| Advantages of monoblocks 04-28-14: AtmasphereGeorge's comment about ground loop issues is incorrect.Saying "incorrect" itself, is a typical incorrect "blanket statement"As I said "You have a greater chance of (hum) earth loop problems with monoblocks" Emphsis on "greater ... |
