| Best Tubed Preamp For A Warm, Rich Sound, Yet Still Detailed and Agile While the description of the Innamorata at the Wells Audio website as well as in various reviews indicate its input impedance as 50K, its manual indicates 30K. I don’t know which number is correct, of course, but 30K would be somewhat marginal (or... | |
| Best Tubed Preamp For A Warm, Rich Sound, Yet Still Detailed and Agile What amplifier will you be using?There have been many worthy suggestions, but as Georgehifi alluded to earlier impedance compatibility with the amplifier needs to be considered. Also, compatibility with the amplifier in terms of gain, and with res... | |
| To Shield or Not to shield-That is the question!!! A few has said the cables sound much better without a shield. One situation in which an unshielded balanced cable may sound best from a subjective standpoint is if the cable is driven by a component having particularly high output impedance. The l... | |
| Do blown preamp tubes cause other issues? Wolf_Garcia 4-5-2017...it would seem that the preamp just stops working when a tube blows, and isn’t likely to dump anything beyond (maybe) some noise into the amp which I suppose could stress the speakers. Regarding the latter possibility, I once... | |
| Silly Question Not a silly question, even though the manual for the DS Jr. states that "it is fine to use both outputs at the same time," referring to the RCA and XLR outputs. I looked at the manuals and descriptions of the DS Jr. and the KRC-3. The relevant imp... | |
| 500mV (0dB) on the voltmeter? Can’t understand why they would "arbitrarily" refer to something in the service manual. In the context of voltage a given number of dB refers to the ratio between two voltages, as I indicated. Therefore "0 dB" must be defined as corresponding to *... | |
| Synergistic Red Fuse ... Hello Kalali,"3AG" is not a current rating. It defines the fuse as being glass and having a physical size of 6.3 x 32 mm (1/4 x 1-1/4 inches).Beyond that, I have no knowledge of what the MMG may require.Good luck. Regards,-- Al | |
| Amps Atma-Sphere M-60 Mono blocks OTL design Doesn’t using zero transformers defeat the whole point of an OTL amp? It’s putting a transformer in and makes it similar to a non OTL push pull tube amp. That’s a logical question, which has been stated here in a number of other threads in the pas... | |
| Can a rca/xlr converter work in reverse?? I see that the Genelec DI8A uses active circuitry to accomplish the conversion, so it definitely cannot be used in reverse. You would be connecting two actively driven outputs together and connecting two inputs together, instead of connecting an o... | |
| 500mV (0dB) on the voltmeter? I took a look at the service manual, at hifiengine.com. It appears that they are somewhat arbitrarily defining 0 dB as corresponding to a voltage of 500 mv, with other voltages that are expressed in dB undoubtedly being related to that 500 mv leve... | |
| If NOS pre or power tubes became unavailable altogether, what new tubes would you buy? Thanks, Lowrider. Speaking of terminology, I should be more precise with my own. The number of megohms (millions of ohms) that I referred to as heater-to-cathode leakage is more properly referred to as heater-to-cathode resistance. "Leakage" wo... | |
| If NOS pre or power tubes became unavailable altogether, what new tubes would you buy? Hi Lowrider,Heater-to-cathode leakage is not a specified parameter in the case of most tubes. For example, that parameter does not appear in the GE datasheet that is linked to in Sophia’s description of their 6SN7. Also, it’s not a voltage issue i... | |
| Brightest but shortest artistic bursts in the sky Schubert 4-1-2017Of all the humans who have ever lived that title is held by Franz Schubert. Period . I agree.BTW, Schubert, good to see you posting again!Best regards,-- Al | |
| Mcintosh Question- Looking for feedback Also can someone give me the shortened version on why Mac has different speaker connections for different ohm speakers? I accustomed to wattage doubling in 4 ohms. Many of the McIntosh solid state amps are unusual in that they employ an autofo... | |
| If NOS pre or power tubes became unavailable altogether, what new tubes would you buy? A cautionary note about the Sophia 6SN7: See the following thread from 2012, in which I and another member both reported that it caused hum problems in our VAC Renaissance amplifiers, which I determined was due to excessive heater-to-cathode leaka... |
