| Problem with bi amping speakers What am I doing wrong?Good question. Nothing that is immediately obvious to me. If you have a multimeter available, what I would suggest for starters is that you disconnect the speaker cables from the speakers, and with the jumpers removed verify ... | |
| RCA or XLR Between Digital Separates? Thanks very much, guys. Enjoy!Best regards,-- Al | |
| Can a rogue audio Cronus be used just as a preamp? A follow-up to my previous post. It is conceivable that with some designs a suitable alternative to load resistors would be to simply remove the power tubes. That would avoid the inductive kickback problem, but would create the risk that internal ... | |
| Can a rogue audio Cronus be used just as a preamp? Can I buy a 200 Watt plus outboard amp and use the Cronus as a preamp only?No, you can't! At least without connecting load resistors to the speaker outputs of the amp. And the resistors would have to be rated to handle high power levels, and shoul... | |

| RCA or XLR Between Digital Separates? While in general I would expect an AES/EBU interface to provide superior performance, for the reasons that have been stated (and also due to reduced susceptibility to jitter that may be induced by ground loop effects), the following are some facto... | |
| Pass XA Monoblock Amps Inna, I have no particular familiarity with the Cardas GR's, but from a specification standpoint, at least, I don't see any concerns. Resistance and inductance are extremely low. Capacitance is a little bit on the high side, but I would feel certa... | |
| Pass XA Monoblock Amps A point that might be relevant is that speaker sensitivity is often defined with respect to 2.83 volts, rather than 1 watt. For an 8 ohm speaker that would make no difference, since 2.83 volts into 8 ohms corresponds to 1 watt. But 2.83 volts into... | |
| Interconnect question The chances that changing your preamp-to-amp interconnect cable will make a significant difference are increased if:1)The output impedance of the preamp is high, which is most often the case if it is a tube-based preamp.2)The preamp-to-amp connect... | |
| EE Minimax Plus DAC vs. Rega DAC Among the conceivable rookie mistakes that Foster_9 wisely expressed concern about, and beyond the obvious ones like plugging the device in rotated 180 degrees, I would highlight the possibility of damage to the op amps, or degradation of their lo... | |
| Have I mismatched my preamp/amp? I composed the following before seeing your last post, about 100K/47K. I think you would have probably been ok even if it were 10K:The usual rule of thumb guideline is that power amp input impedance should be at least 10x greater than the output i... | |
| Can S video cables be used as digital coax cables? I doubt that would work well, unless your DAC has essentially perfect jitter rejection. S-video cables conduct two separate high frequency signals (luminance + sync, and chrominance), and have two corresponding return conductors. Passive S-video t... | |
| Speaker wire gauge 18 gauge. You can calculate that from the resistance numbers in this wire gauge table, by dividing the resistance number for 24 gauge by 4, and looking up the corresponding gauge.Regards,-- Al | |
| Good Tube Selection for Atma Sphere S30? Thanks, Ralph. Excellent info.What prompted my question is that I am using a matched quad of a highly regarded and expensive current manufacture 6SN7, of Chinese (not Russian) origin, which in some sections of some of the tubes measure as low as 3... | |
| Good Tube Selection for Atma Sphere S30? 12-14-11: AtmasphereIn practice, tubes with leakage can buzz ... Ralph, assuming you are referring to heater-to-cathode leakage, how many megohms of leakage resistance would you consider to be the threshold of acceptability for a 6SN7, as measured... |
