Dan, There's a difference between measurable sonic accuracy and good sound. Solid state guys always use THD, (total harmonic distortion), as the yard stick. I use my ears. These ears are capable of noticing a 1dB difference is channel separation.....much to my dismay....it means I'm forever tweaking!
Low THD numbers are usually achieved through the use of negative feedback in the audio circuit. This however does NOT translate into good sound. The old Grundigs had good sound because they were big and heavy with inert cabinets. The German tubes used in the Telefunkens ETC were vastly superior to most cheap and cheerful tubes. The mulitple speakers can be good or bad. Depends on the crossover, design, etc... Those old systems has warm, rounded sound. The new stuff that I listen on has all the psychoacoustic benefits of tubes without the rolled off top and bottom ends. As I'm writing this I keep thinking of all the tiny things you can do that have large effects on the sound quality overall. 78's tend to have been recorded acoustically...basically by shouting down a megaphone attached to a microphone. Also, the shellac used as a medium had a limited range. Still a very interesting and enjoyable sound nonetheless. I even almost bought an Edison Amberola a few years back. (wax cylinders) A push pull circuit gives you more power, but at the price of purity of sound. Still great sound though....but 40 amps....???? WOW! Turn on your amp and the streetlights dim! AWESOME. My old GE kettle was like that! lol My 845 tube monblocks used to warm up the apartment too! Noticeably!! Jeff Zedic Long-winded when it comes to audio No more MB's either....have to settle for my Audi A4 TDI 5 speed!! Woohoo!! _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
