I chose the EdgarHorns for fairly simple reasons. I have listened to them and I loved the way they sound. They are not the perfect loudspeaker, but they make much truer music than what I have now. Also, the price I paid is less than...

[quote user="manisandher"]This is very disappointing to hear.
But in a way, it makes little difference to me. I had decided that I would only use the PP2000 from battery power when listening to music (or making vinyl transfers to digital). I'v...

[quote user="AOK_Farmer"]I think what they did was to put filters, maybe just a simple capacitor on the AC side to try and reduce the noise that the units inject back into the ac mains. Perhaps they were getting complaints that the units worsened the...

[quote user="Steradian"]
Look at the popularity of 5.1 and 7.1 "multichannel" (not DSET) sound nowadays. Stereo audio is a dying breed. The public is choosing 6-8 channels of MP3 quality sound. They can't put together a satisfying 2 channel...

I separated my two of my PP2000 in my rack with 3 feet space and run everything from one PP2000 and both Milq power amps from another PP2000. I also routed the incoming power cords that that are far from each other and far from outcoming power co...

[quote user="drdna"] It is not exactly correct. There is 60 Hz hum eliminated by lifting the ground to the amplifiers. The neutral is connected to the ground prong and chassis in the amps, so I assume it is setting up a loop. However, there is a seco...

[quote user="Romy the Cat"]In the end I feel that the PP2000’s softness/politeness is not a liability but opportunity. I certainly not willing to go back to the softness/politeness lacking type of sound and I would like to make my playback to be able...

[quote user="op.9"] One thing nobody has mentioned is using the room’s corners. Is this a no no? I’ve been trying use McBean to model a horn exiting into the corner – with a middle ‘mouth’ about 1m squared - and using a conical approximation as the r...

[quote user="Romy the Cat"]Eli, I do not think that it is PurePower objective to grab your money and to run. They are notorious with delays and it certainly might be unpleasant. With all due respect: 2 month delay is kind of nothing and if the unit ...

I am in academics. In this world it is no challenge to find people who want to tell me that they are right and everybody else is wrong.The problem with any scholar stuck in his/her theoretical bubble is that there is no room for that person to change...

[quote user="KOTriode"] On dynamic, the 6C33C tube showed its ability to go deep in the bass on Ray Brown trio recording of Soular Energy which is excellent for a 15W SE , the 845 amp can do better, but not by much, but probably because of its 25W ou...

I’ve been thinking about all this electricity stuff…
I’ve stopped using all power conditioning devices since Bush got re-elected, and I consequently left the country to start a new life in the land of 220v/50Hz (this BTW, is not an exaggeration).

[quote user="drdna"]I would not restrict myself to the idea that things need to be a certain way or a certain configuration of the drivers or ports based on theory alone. I think it is important to ask what is interesting about the sound that the new...

Actually I do not think that it “all about money” but rather about “those” people who exercise nothing else then thier own Moronity. Ignorance is a state when a person recognizes that something is wrong but do not know "w...

I did not read it, I rarely read those types of articles but what you describe is very common and very indicative for those people. They fly like butterflies from a manufacture to a manufacture, from dealer to dealer and from marketing campaign to ma...

Romy,
Your approach makes sense; I will look into fitting a "12.5 db voltage divider".
As I did not have any noise issues when using the same equipment with a variety of direct radiating speakers, I can only speculate as to what other informat...

Ari,
I do not think that we recognize the process of “audio designing” as the identical actively. It looks as you peruse to design an amplifier (for instance) as a conceptually well operating system where a set of deferential abstractly-measurable v...

After much research I found the radio that I like. The decision was base mostly on the esthetic: size, color etc, sure I was conserving the circuit but only up to point. The choose when for German Schaub & Lorenz Goldsuper W42. It is 1957 ra...

Hi Mats:
Thanks for the update. I find the Lavry DA-11 to be an interesting unit, not because of all the "features" but because of Mr Lavry's long history producing serous DACs and the consumer-friendly pricing. I do wish that Mr Lavry did...

these are my findings about computer audio after some trial error:1. computer audio is very very hardware/OS/software dependent. computer structure is multi task (time sharing) and using it as a real time single task processor is not easy.even small ...

All Acoustic System or let say playbacks has signature or some kind of own character of sound. That is normal we all accept it and live with it. It is important to differentiate a character of playback from major mistakes of playback, but it is a...

I started in hi-fi with LPs and I have never stopped using them as my principal source for hi-fi. Some time ago I decided that master tape was better than vinyl, but I could not afford to go that route; so I settled on the next best thing: a cartrid...
