| Who needs a MM cartridge type when we have MC? I want to win...dick | |
| Am I going to need a step up transformer? The difference between .28 and .34 is less than 2dB so you should be fine.The closer you are to full volume the better your system gain is set up. Excess attenuation (hair trigger volume controls) just means you are amplifying (adding distortion) ... | |
| Does the volume control effect sound quality? Hey Dracule1Never had a problem with miller effect and inductive volume controls. Mainly because with an autoformer, worst case is at full volume when the output impedance of your source drives the miller directly. As you attenuate the autoformer ... | |
| Does the volume control effect sound quality? 10K square wave on every tap (unloaded) of one particular inductive volume control.http://www.intactaudio.com/forum/files/slagleformer_558.gifSame test on another popular inductive volume control.http://www.intactaudio.com/forum/files/0db_129.gifS... | |
| Tube amplifiers and interstage transformers hey,Measurements do have a relevant use, they just aren't useful as a predictor of sound quality.bingo! Measurements are objective, sound quality is subjective and there is a word that describes ambiguous blending of the two in order to manipulate... | |
| Tube amplifiers and interstage transformers This might not be an appropriate response but system synergy is the only thing that can give you what you want.The problem is, you need to know what you want prior to asking the question or you risk a 1000 post thread from others telling you what ... | |
| Amp recommendations for stacked Quad ESL 57's When you stack the quads, how do you wire them?The reason I ask is I have heard a setup with three '57's per side all wired in series work amazingly well with a ~12W amp. It wasn't one specific 12W amp either, I have herd the Radio Crafstsman C-50... | |
| Tube amplifiers and interstage transformers The use of the term "impedance matching" isn't really appropriate for the majority of interstage transformer usage.Typically output transformers are used to "match" the high impedance of a tube to the low impedance of a speaker so they usually hav... | |
| 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... |
