| The future of preamps 12-19-13: GeorgelofiNuforce dac 9 has RCA Output impedance: 0.01 Ohm.I see that in the specs at their website, and in the manual. Surely it is a typo, though?Regards,-- Al | |
| Which component is most responsible? IMO a general purpose answer to the question is neither useful nor possible. Differences between systems, rooms, recordings, and listeners will inevitably mean that the weakest link has to be identified on a case-by-case basis.FWIW, though, if the... | |
| CD player outputs question..... Doing that won't hurt anything, and it will most likely function in a reasonable manner. I can envision a couple of ways, though, that there MIGHT be at least slight adverse effects on sound quality.One issue might be an increase in ground loop-re... | |
| The future of preamps Michael (Swampwalker) & Charles, thanks very much for the nice words.12-14-13: AudiolabyrinthAlmarg, Can you look into this for me, the spec of 18 volts input to clip, this is the max input told to me over the phone by krell, you can do more o... | |
| The future of preamps An additional point: The 700cx is spec'd as being capable of putting out a maximum output voltage of 84 volts RMS. Based on the amp's voltage gain of 20.89x (see my previous post), that output voltage would be produced by an input voltage of:84/20... | |
| Mono amps and different length speaker cables 12-13-13: KnghifiWhy take a chance and just use 2 same length cables. Why assume that unequal lengths won't be better than equal lengths? As I indicated earlier, I see no reason to make that assumption, at least in the biwire situation the OP appe... | |
| The future of preamps The specs indicated in the manual for the Krell 700cx are 3.58 volt sensitivity (for its balanced input), 26.4 db gain, 700/1400/2800 watts into 8/4/2 ohms respectively.26.4 db is a voltage gain of 20.89, based on db = 20log(Vout/Vin).20.89 x 3.58... | |
| Mono amps and different length speaker cables 12-11-13: SimaoAgreed with Mustang. You're talking 3 feet for signals traveling close to light speed. I agree with Mustang also, as implied in the last line of my earlier post.However, the fact you cited that signals propagate through wires at nea... | |
| The future of preamps Ralph (Atmasphere), thanks for the link and the comment about CAST. I see what you mean, and I agree. So I have no idea what the 18 volt figure mentioned by Audiolabyrinth would pertain to. That figure does not appear anywhere in the manual, btw, ... | |
| Mono amps and different length speaker cables I for one don't see anything weird about the question. Not sure if it's clear to everyone that he is apparently referring to biwiring, with one length going to one section of each speaker and the other length going to the other section of each spe... | |
| The future of preamps Audiolab, what Atmasphere said about voltage levels is essentially correct (given my subsequent clarification), although his comment is most probably not applicable to the proprietary CAST interface that is provided on your amplifier.For conventio... | |
| The future of preamps 12-10-13: UnsoundPerhaps I've been misled, but I thought the redbook standard output was 2 volts?I haven't ever had occasion to look at the redbook specification document, but the de facto norm seems to be "full scale" (i.e., maximum) amplitudes o... | |
| Yamaha P2201 Connections Yes, you would only use one connector for each channel. With the adapter I suggested, that would be the XLR female.I had looked at the manual for the amp before responding earlier, and it indicated that all four input connectors on each channel ar... | |
| Yamaha P2201 Connections See my answer in your other thread.Regards,-- Al | |
| RCA Preouts to Yamaha P2201 I would suggest using an inexpensive RCA-to-XLR adapter such as this one. In doing that, the "input polarity" switches on the rear of the amp should be set to pin 2 hot.In many such circumstances using a Jensen transformer, such as their model PI-... |
