| Preamp - 18 dB Gain too low? Hey,'between 3-5pm' are just arbitrary numbers and without seeing an actual attenuation plot vs. knob rotation of the LDR, you really don't know that much. Also seeing an input and output impedance plot of the device WRT attenuation would be neede... | |
| Mismatch - between SUT and MC cartridge. Say your cartridge is 10 ohms and the SUT was designed to load a 2.5 ohm cartridge. This means that the low end bandwidth will be two octaves less due to the fixed inductance. Depending on the design choices and system matching this could be a goo... | |
| Preamp - 18 dB Gain too low? Coming into this late but the first thing you need to do is differentiate between gain and attenuation. Gain is fixed at 18dB and attenuation is variable.The 800 pound gorilla in the corner is lumping gain and attenuation into an arbitrary setting... | |
| Sound of transformers in preamps? Wrt distortion, unbiased transformers create odd order harmonics due to the bh loop symmetry around the origin. Tubes like solid state devices are nonlinear in an asymmetrical manner so they create predominantly even order distortions. In order to... | |
| Has anyone listened to the soundsmith Paua cart Peter was referring to the value of the load. I was referring to the magnitude.Again. While 1K represents a "minimum value" it the absolute sense, it is the maximum load.dave | |
| Has anyone listened to the soundsmith Paua cart Viridian,Actually we are on the same page. It is just another one of those situations like electrons flow from negative to positive yet current flows from positive to negative.dave | |
| Has anyone listened to the soundsmith Paua cart Andy, you need to place the word "value" after the word minimum to make your statement correct. "1K is the minimum value load" or conversely you could say "1K is the maximum load".It all comes down to the proper definition of minimum and maximum l... | |
| Has anyone listened to the soundsmith Paua cart Hey,The low output SS carts can use a SUT, you just need to be aware of the 1000 ohm maximum load. Assuming the 47K input impedance of a phono stage this limits you to a 1:7 step up ratio (I'd look at 1:5). The other option is of course to yank th... | |
| 47 Labs RS-A1 tonearm, how to adjust VTA ? Assuming your VTF is correct and you have the arm positioned properly (stylus 1CM from center pivot) then the next thing I would check is the tightness of the headhell rotating bearing. I find if that is too loose things can get a bit aggressive. ... | |
| 47 Labs RS-A1 tonearm, how to adjust VTA ? Hey,you can get away with a small amount of adjustment on the 'pillar' but the rotating plate really should be level. If gross VTA adjustment is needed your only option is to shim the front or the back of the cartridge body.dave | |
| Which Mono Cartridge at around $1,300.00? For anyone in the Dallas area, the LSAF is this weekend and I'll have a shilabe and a premium Be mounted up for some fun stereo vs. mono comparisons in a zero pressure tequilla fueled cinco de mayo environment. (will be there on siete de mayo too)... | |
| Active or passive preamp Hey,John still sells the naked units and OEM's them to Experience Music, Purity Audio and a few other high end manufacturers have proprietary versions. Artemis Labs, Aprilsound and Thomas Mayer all use a version of the autoformers in their top lev... | |
| Active or passive preamp Hey,The Z-out is a function of three things. Source impedance driving the inductive volume control, step down ratio and DCR of the coils.In the case of an autoformer with a 50 ohm DCR the Zout is as follows. (numbers quickly read of a log graph so... | |
| what is the proper loading This makes it simple.Listen to the two extremes (17 & 220) and determine what you like and dislike about each.hopefully the likes and dislikes will be apparent at which point try the 69 for a bit which puts you in the middle and see if you get... | |
| Einstein TTC phono - Making Loading Plugs Help To me your results suggest an unloaded input impedance of 470 ohms (By chance does it use a 1:10 SUT?)In any case the numbers work out close enough and you just need ot find the resistor to use in parallel with 470 ohms to get your desired load.
