Room Acoustics
Most "mild" room treatments utilizing thin layers of foam and / or "stuffed" cloth materials, etc... are actually very non-linear in their absorption of frequencies. I commented on this many, many years ago in the Agon archives and posted links to... 
Will this isolation transformer limit power draw?
An outboard bank of caps is FAR less effective than capacitors placed as close as possible to the output devices. That is, as far as storage devices go and minimizing sag on the rails.As far as the 60 Hz voltage vs the rail voltage goes, the 60 Hz... 
FABULOUS guitar wanking
Duane: Somehow, i knew that this guy was going to be "old hat" to you : )Isellstuff: If you don't mind, what clubs in IL does he tend to play at? I'd love to see this guy live, just to see if he can duplicate what he does on record. I've seen WAY ... 
Amplifier Speed
The time it takes for the signal to travel from the input to the output would be dependent on the length of the circuit and the velocity of propogation through the circuit. This is technically referred to as Td, hence my comments about the lack of... 
MC352 into varying-load speaker?
Kck: Autoformers act as a buffer. If you have an anemic amp and a speaker system that presents a wild and highly reactive impedance as a load, that "buffer" could be a good thing. Otherwise, that "buffer" acts as a sonic veil between the amp and s... 
My first tube integrated amp max $500 new/used
Boy, has this thread gotten sidetracked. For once though, it's not my fault : )All i will say is that if Didactically wants low distortion measurements, we'll give him a system with 100 dB's of negative feedback that is extremely bandwidth limited... 
Audiogon Newsletter
Mine came Saturday evening, but it looked "funny" to me. Come to find out, it was HTML encoded and i have my mail set up to read plain text. Once i turned on the HTML after reading this thread, it looked "better" and more like Agon ( colour and la... 
How Loud Do You Listen??? Do You Know?????????
When discussing average listening levels, one needs to specify where the reading is being taken. For sake of consistency, placing the meter where your head would normally be and having it set up with the mic facing straight forward between the cen... 
Will this isolation transformer limit power draw?
El: an amp that derives its power source from the audio signal would be lower in linearity than a Class C amplifier. The end result would be that gobs of resolution would be lost. After all, rather than pass all of the signal onto the gain stage f... 
MC352 into varying-load speaker?
Kck: I am not a fan of "autoformers" in the least. To me, they are blasphemous. If you really want to know my thoughts on them, fire away with questions. Just don't expect "politically correct" answers. Sean> 
Will this isolation transformer limit power draw?
El: Here's a few responses to your questions:1. If a transformer removes "grunge" (that must be some technical term that I am unfamiliar with) why doesn't the transformer that is already in the audio equipment do the job?Transformers do remove AC ...

How many manufacturers actually quote Td ( Time delay ) for a component? I've only ever seen one company ever provide this spec. Sean> 
$1200 vs $200 cd players
Some inexpensive players sound fantastic for what you pay for them. Having said that, some more expensive players & digital combo's add more refinement at most every level of performance. While i'm not directly familiar with the Arcam gear, wh... 
MC352 into varying-load speaker?
As with any speaker that uses a passive crossover, some of your power is lost in the crossover itself. On top of that, speakers that use contouring networks, notch filters, impedance compensation, etc... all end up sucking up more power. While the... 
Will this isolation transformer limit power draw?
You need a bigger transformer. With a max current rating of slightly over 720 watts, the absolutely smallest transformer that you should think about using should be at least 1000 watts with with a very heavy core. You can always try using the tran...
