    • I noticed the incredible response to the Little Sweetie project.  Is there interest in another project?   I have designed a new amp for my Klipschhorns which is novel in that it offers variable harmonic augmentation (referred to as distortion by Neanderthals).  The augmentation can be biased to odd harmonics, even, or both, and more uniquely it can adjust how flat the augmentation curve is, that is it can augment only the initial modes or can proceed way up the chain of overtones. Or at least the simulations in LTSpice predict that it do all of that.  The real test will be after it is built...
    • Unfortunately Klipsch does not make 600 Ohm headphones.  I must use 600 Ohms to load the tubes in my OTL headphone amp.   Until last week I thought I had a solution for the cottage.  Inclining the walls out 30 deg. in combination with 18" ceiling beams simulated beautifully.  Sadly my wife and my architect did not go for the inverted pyramid.     If there was one solution there must be another...

    • I have inherited a very old A6 , at least that’s what I think it is. My dad said he built it from a kit. I’m guessing it’s from 1962. I only have one. Any suggestions as to how I assess the value of this.  I’m looking to sell. Thanks 
    • you're SOL doc... get some headphones. Sound clouds will help slightly... but you will struggle massively with your Schroeder frequency
    • It’s 15°in SP. Ive got to drive the estranged wifey to a doctor’s appointment this morning. Very appreciative of the heated seats in the Honda on a day like today.

    • Most posts address solutions for existing rooms and problems.  In this case we can suggest solutions before the problems have been built as the architect is just starting work on my retirement cottage.  However there are a few major challenges posed by the site.  The cottage will  span a ravine which cuts through a bluff above a National Scenic Waterway.  This means acres of glass to appreciate the view.  As it is a retirement cottage there will not be a separate listing room or theater.  The great room (perhaps 40x22 and sheathed in one long wall of glass and including an open kitchen) must perform all functions.   I have a pair of Klipschhorns (1988 and re-caped), a pair of La Scala's (1976), and a pair of Klipschish shortish horns of my own design to contribute to the room, and 24 Watt Tube amp of my own design to drive them.  I could build a monoblock Tube amp for center channel if desired (yes, I capitalize "Tube").  I also have a friend with the software to perform simulations once we provide him with the constraints.  My initial ideas include the following: 1. Exposed beams in the ceiling to act as sound dams 2. Sunken listening area 3. Elevated or vaulted portions of the ceiling 4. Partial walls partitioning the kitchen and entry so some sound is reflected and some passes over and through openings   And adding to the challenge there will be no carpet.  A giant Oak tree blew down in my forest and is being sawn by a local saw mill for the floor. (it might be a live-edge floor, but in any case planks of 2-4 ft. width)   Perhaps the only good news is that there is no concern with isolation of of sound from the rest of the cottage.  If things are loud my Wife and I will be there!   All ideas will be greatly appreciated...   Dr. Hillbilly (the doctorate is in Mechanical Engineering, not Medicine) 
    • Coffee's good.  What's new in here?  3 in Duckburg this morning, light snow and we won a lil football game last night.          
    • I like it when these old threads are brought to the top.
