NUPRIME EVOLUTION ONE-BEST CLASS D AMP ON THE MARKET
"conventional ABamps since its prehistoric technology going back 50 tears" sicSo, my single ended triode Class A amps, using tubes introduced in 1929 suck because they are prehistoric? Class D was invented in 1955. It has taken this long to make t... 
Considering simplifying my system... talk me down (or whatever)
Unless you plan on moving it, what could be simpler than doing nothing? 
Cables of the past - which still rock?
Take a look at the prices and availability of used cables on Audiogon. Why would you buy new? 
RMAF 2019!
Sanders Sound Systems by far the best sound. The only speaker I wanted to take home. The least impressive looking room.Focal Scala Utopia my next favorite speaker.The Sigma Acoustics/AGD room was where I spent the most time. Sounded mostly beautif... 
Why bookshelf type speakers are not high end
The difference between 30hz and 20hz is 5 notes that only a pipe organ or electronic synthesizer can make. 40hz is an octave. A few instruments can get lower than 40hz. Anything below 20hz is movie sound effects.As far as the price is concerned, i... 
The Truth about Modern Class D
Hey @jdl57 - I have heard the effects you are talking about in a number of hotel rooms. It was poor room acoustics.This was in a large conference room, much bigger than any room would be in a normal house. The speakers they were using was the Sigm... 
The Truth about Modern Class D
I have heard this amp touted as the best amplifier ever made. By contemporary standards it is not horribly expensive, but it is also not cheap. Through most of it’s range it was absolutely beautiful. I listened for a long time because the system s... 
The Truth about Modern Class D
O.K. I just got home from the first day of the Rocky Mountain Audio Fest. There were two things I was excited to hear: the Kii speaker system and the AGD Vivace amps. The Kiis were a non-starter. Although I didn't do a long audition, I didn't like... 
Your favorite Electrostatic, Panel spkr
Actually, I was reading a post a while ago on DIYaudio.com. It was about the power switch on the ML-2. John Curl answered it and stated that he was not involved in the final layout of the ML-2, he had worked on the project however. Tom Colangelo i...

Your favorite Electrostatic, Panel spkr
I'm glad to see Sound Lab mentioned so many times. I have owned the same pair of Sound Lab speakers, model A-2, for 35 years. They are the smallest pure electrostatic Sound Labs ever made. They are a two way. Even though I have lusted after the la... 
what do horns sound like
This will be a long post, I apologize for that now, but I have been on a journey that might enlighten you. I became a die hard fan of single ended triodes about 20 years ago when I built one. It uses the 45 tube and puts out 2 watts per channel. I... 
SET amplifier recommendation
@atmasphere Just out curiosity, I plugged the ACA into my 89db efficient Sound Lab electrostatics (the 805 is 88db), and my Vision Acoustics Soloist (air suspension 88db), and yes it will drive the B&Ws, and probably quite well. 
SET amplifier recommendation
I have an idea that might work, emphasis on the word might. This amp right here: https://diyaudiostore.com/collections/amp-camp-amp/products/amp-camp-amp-kit?variant=7072933085218 is an easy to build single ended transistor kit. It sells for $327,... 
What was your first big eye opener with regard to audio?
My life changing moments:1.) Infinity WTLC (after the Servo Static and before the EMITs, used a Walsh tweeter) , Phase linear electronics. The system that started it all, it demonstrated to me that stereos could make a 3D soundstage. Soundstage ha...
