Need Some Answers Building My First Home Audio System, and using Cornwalls
For the most part it seems you've had some pretty good advice- given that you don't want to use tubes.Here's something to think about though! The Cornwall was designed to be played with tubes (the speakers made in the 60s were the same as the orig... 
Solid State Amps for Quad ESL 57?

Why are low impedance speakers harder to drive than high impedance speakers
 Ralph, you mentioned 'former' twice in the last part of your post.Ach!That should read: Again, this all comes down to intention. Is your intention to get the system to sound as good as it can or is it more important to simply play loudly? If th... 
Give me a straight Doc how bad is it?
Play it and see. I used to see bent cantilevers all the time when I did consumer electronics repair putting myself through college. I've straightened many of them. As long as there isn't a dent in the cantilever you are fine. A dent will cause it ... 
Need help with DIN to RCA phono cable troubleshooting
^^ Actually except for the balanced thing, Dover and I were on the same page. I thought I had made that clear in my last post.I do feel I should clarify some things in **your** post however :)  (please note that I am not quarreling) First, if an X... 
Solid State Amps for Quad ESL 57?
^^Thanks!If you were planning to use an SET on the 57, you would likely use the 16 ohm tap. You would get a similar proportionate spread in total output power.However, the total output power does not represent what you would actually hear in pract... 
Why are low impedance speakers harder to drive than high impedance speakers
When this is true, the 4 Ohm is usually 3 dB more sensitive. The low impedance causes extra current flow which provides for increased force against the same magnet.This seems to require clarification!Given two drivers of the same **efficiency** (1... 
Need help with DIN to RCA phono cable troubleshooting
I don’t think this is optimal in a signal ended system. The fifth pin grounds the arm. You run the risk that if someone connects the shield to the RCA at the preamp end then an earth loop is created. You are correct, however the comment was made... 
Why are low impedance speakers harder to drive than high impedance speakers
you took my statement out of context. Here is what I actually said:Yes- it was not to contradict you, but to use the phrase as a talking point, as I see that approach recommended a lot. Then later people sell off the gear in search of that holy g... 
Why are low impedance speakers harder to drive than high impedance speakers
So why would a designer go the other direction?Lower impedances have appeared as a means to get more power out of solid state designs. But this is very different from getting lower distortion! So a lot depends on what your goals are!I think the tr... 
Need help with DIN to RCA phono cable troubleshooting
Should the ground wire from pin 5 in the Din5 connectorbe split in two such that each can be soldered to the pin 1 on theXLR connectors? Or should only the (floating) shield of both channels be connected to the pin 1 on the XLR connectors? The gro... 
Class D Technology
What they call "Analog Cell" is just class A Mosfet input stage very common in many class A or AB amps.  It sounds like a lot of hot air (for class D).Some sort of input buffer is almost always required to eliminate input offsets in the comparat... 
Power supply hum transmitted to loudspeakers
have had their power supply upgraded, but still has a small amount of buzz at the loudspeakers, not audible while playing music beautifully.(with and without shorting plugs). I've learned to ignore it and realize the amplifier was meant to play... 
How many records can a stamper press?
Stampers go about 800-1200 copies. This is defined by the pressing plant more than it is the label. 
Headphone question
Suffice it to say that EVERY recording you own has been run through an equalizer in the mastering process. This statement is false. Many recordings are mastered without any EQ (other than RIAA curves)! If the recording engineer knows what they a...
