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. T... 
Tube amps known to have a low damping factor?
ralph noted...a *lot* depends on the speaker and the designer's intent!AMEN. Look backwards from any driver after a crossover and let me know exactly how high (or low) DF can be a meaningful figure of merit.dave 
Ideal SUT for Lyra Olympos cartridge?
The ideal SUT for the Olympos? - that was the initial question, wasn't it?Simple and straight answer: a SUT with a primary matching the inductance of the Olympos' coil source inductance.Further look out for maximum bandwidth (= lowest phase shift)... 
Why no remote controlled discrete resistor volume?
John Chapman does a number of resistive based remote units using logic and high quality relays to do the switching.http://www.bentaudio.com/remotes/oem.htmldave 
Schroder sq and the new talea
The Triplanar uses a bearing that is harder than either of the arms in this discussion. The schroder arm uses a magnetic bearing that doesn't show wear in the traditional sense and furthermore any "wear" that "may" show up can easily be corrected ... 
2010 RMAF Analog Reports + Meet and Greet
I'm not sure and they were not giving out any free info. I did realize that this happened on a trip to the LSAF and not CES and I actually pulled a Genrad 1203 out of a bag and carried it on in Dallas when I exceeded 50 pounds for a bag on my way ... 
2010 RMAF Analog Reports + Meet and Greet
In the past month, people have called me asking about flying with benign things like tonearms, tubes and transformers. I usually carry on all kinds of valuable yet odd looking things and check the obscene. I occasionally get the second check but i... 
Why mono?
Hey,It is done externally with a jumper.Leave the Red wire connected as is, Move the green headshell lead to the blue cartridge pin and place a jumper from green to white. and use only the right channel of your phono pre. This will sum any lateral... 
Why mono?
Much of the benefit form a true mono cartridge or a mono wired stereo cartridge comes from the idea that only lateral movement of the stylus generates sound. A true stereo cartridge generates information in both the lateral and vertical direction ... 
Why mono?
Hey Jazzdoc,Have you tried putting the coils of a stereo cartridge in series to sum for mono?dave 
SUT for Lyra Clavis Evolve 99
Out of curiosity, what happens when you use the cartridge directly into the phono without a SUT? That will net you 24dB less overall gain. Give it a try and don't listen for absolute sonics but to get a feel for the gain and noise you have in your... 
Lightspeed Attenuator - Best Preamp Ever?
Milpai,What is this CD you talk about? Is it some kind of new format? Obviously recording levels are all over the map and ultimately it is up to the end user to educate themselves and see what works for them or be doomed to repeat the same mistake... 
Lightspeed Attenuator - Best Preamp Ever?
Hey Milpai'you stated: "any passive converts the extra voltage to current"This is true for inductive based units. Resistive based passives turn the extra voltage into heat. dave
