HELP-woofer moves alot when playing lps
Dan_ed, At the very least, yes, though I don't understand what you are getting at at all. I feel like you are misunderstanding something though as there appears to be animosity on your part.So maybe I have not been clear enough:Woofer pumping is n... 
Why 24/7 warm-up period on amps?
I'd like to do a blind test on power cords, too. Power goes all over the county on high voltage lines, step it down at ana xformer, goes through the house in 12-14 AWG ROMEX, through a gazillion dollar power cord that magically realigns the power ... 
What will raising the Va of atransformers provide?
Dcarol, it appears that you are not addressing Stanwal's point about a class A amplifier. I agree with him- if the transformer for such an amplifier is up to the task in the first place, a larger transformer is not going to make a difference, high... 
HELP-woofer moves alot when playing lps
Hi Dan_ed, I have a Triplanar too :) -and no, I'm not saying that. If set up right it handles the widest range of cartridges of any arm I've seen.For more on this, take a look here:http://forum.audiogon.com/cgi-bin/fr.pl?eanlg&1315713166&o... 
HELP-woofer moves alot when playing lps
Tbromgard, despite claims to the contrary woofer pumping is not something that ported speakers are prone to.My speakers are ported and go to 20 Hz. They don't pump particularly more on LP than they do on CD. This is a common problem with arm/cartr... 
Cartridge Loading and Compliance Laws
Correct, if the tables are turned, then you are out of luck.This is not entirely true. Some arms have multiple weight systems, so if you can use a heavier counterbalance weight closer to the arm bearings that will get you lower effective mass as o... 
Best REEL TO REEL blank tape?
All tape machines can be biased for a particular tape. Most of them require that a technician do the work.BTW, if the machine is *not* set up for a particular tape, there is no point in auditioning the differences between tape, as the issues of hi... 
First Watt: current vs voltage
A current source amplifier has a very high output impedance- usually multiples of the speaker impedance.A voltage source amplifier has a low output impedance, usually a small fraction of the speaker impedance.Either one can sound good, but as far ... 
Dynamic speakers for OTL amps
Audiokinesis showed a 2-way speaker at RMAF last year call the Stratoprism that may well suit the bill. It was moderately priced and very easy to drive- with that kind of power and the efficiency of the Stratoprism you would have no worries in a r... 
XLR to RCA Adapters
Kirkus, yes that does sound like a pain. I've always been a fan of bandwidth, well below 20Hz and well above 20KHz to maintain proper phase reproduction in the audio passband. Both areas can be hard for transformers (which is why I prefer to direc... 
Is no preamp the best preamp of all?
Daverz, those least significant bits contain detail.Now to your issue about the 30 db. Think about in terms of a magnifying glass. Without the glass you can see a small object and depending on your eyes, all the detail is there. When you use the m... 
Modern Linestages
Martykl, thanks for the question. I'm not exactly sure how to answer- it might help to tell the story of the MA-3.This is our flagship amplifier. I had the idea of 'something' for a long time but it was pretty nebulous. But along came a customer t... 
Tube Phono Stage vs Solid State What do you think?
I've heard both sound very good. The biggest difference I hear is that tube units might have more hiss, while transistor units tend to play more surface noise. This has nothing to do with the bandwidth of either BTW. Beyond that a transistor unit ... 
Is no preamp the best preamp of all?
Daverz, it does not work that way. If you turn the volume down, and assuming that 0db is your 'floor', the quietest portions will still be at or above that floor. This is true of any volume control.

Charles1dad, regarding your examples- I don't know about all of them but I know about some and those are good examples.
