| Benefit of low output moving-iron Grado ? Cartridge loading is the act of putting a resistance (sometimes, a capacitor and a resistance) in parallel with the cartridge, such that the cartridge is driving the load.We provided a cartridge loading strip on the back of our preamp for this pur... | |
| Preamps with balanced ins/outs and remote With respect to cables, yes, its possible. A lot depends on the design of the transformers. If they are designed to be loaded with the relatively high input impedances that are common in amplifiers today, you will retain the Common Mode Rejection ... | |
| Tube preamp for SS amp If you want a tube preamp to drive a solid state amplifier, the thing to look at is the output impedance at 20Hz. What it is at 1000Hz is really not that important- most any tube preamp will have an acceptable output impedance at that frequency. I... | |
| Replace 12AU7 with 6SN7 ? The two tubes are based on the same tooling. A 12AU7s is exactly half the plate structure of a 6SN7. They have the same gain and bias in a similar fashion. It is also double the filament current. It is probably that fact that might stop you trying... | |
| The future of preamps Almarg said quote- "The 32 volts could be 1000 volts and you still would not have a problem". Yes I would!, I do not want a volume control to fully drive my amp on a clock value starting at 6am going to 3pm being the preamps full out-put, and maki... | |
| Impedance mismatch question Regarding tube preamps would an output trandformer in place of the capacitor eliminate or reduce this potential fluctuating impedance mismatch ?The issue with an output transformer is loading. If loaded at an impedance too low, it will roll the hi... | |
| To Tube or not to Tube...... But does it ever end?? ;)No. And if you do it right, it gets better :) | |
| Benefit of low output moving-iron Grado ? You don't get hum if set up right. If you have a Rega, you might get hum because the motor is not grounded. Easy enough to fix. | |
| Warm, Smooth yet Transparent Amp Hope you are feeling better! | |
| The future of preamps You put a White Paper out on this Atmasphere and you'll be shot down in flames. Mathematically how is the Nuforce not going to control the interconnects to the Belles?? You flat earthers are just too much!!! Actually an article on this subject sou... | |
| The future of preamps if his source has volume control" it will be the most transparent, dynamic, and least coloured way of getting the sound of the CDP/DAC to the poweramps.Georgelofi, this is not really true, unless that source also has the ability to control the cab... | |
| The future of preamps 'Flat earth' usually has something to do with a lack of math coupled with ignorance. Here are the issues of what a passive has to face:With any passive volume control the control element is a series element with the source. The more you have to tu... | |
| The future of preamps Audiolabyrinth, it uses a servo that corrects the DC. The servo also lets you know if there is a problem it can't correct. Its simple, and very reliable. The actual circuit does not want to make large amounts of DC in the first place so the servo ... | |
| To Tube or not to Tube...... Ebuzz, make sure you have checked to see if there are any potential issues with the tube amp driving the loudspeakers you have. | |
| Benefit of low output moving-iron Grado ? You might want to experiment with loading. We had a ZYX Universe that was very nice, one day the needle just decided to let go of the cantilever and that was that.So we installed a wood-body Grado we had on hand. Its 5mV. It was also a little upfr... |
