If you thoughtfully read my site then here and there (particularly in the articles about Lamm ML2) you read my “absurd” comments that the best performing system is the system that do best Sound while the power amplifiers not even plugged in the p...

Last week I spent a few hours at the scene of NY’s Stereophile Show – HE 2004: a half-day on Thursday and 2 hours on Friday. As many other audio-shows it had many semi-ugly colorations, however as any audio shows this zoo trip brought it’s own “inter...

[quote user="decoud"]Romy, apologies for being unclear: the amp is not yet built: this is just a spare chassis I am offering for others who may wish to build it too. Inputs and outputs have not yet been added to the chassis. I therefore cannot co...

[quote user="Romy the Cat"]You decided to go with mA or are they mV against 1R resistors?
I prefer the second approach personally and I feel that I can moderate the quality
of resistor and I can’t moderate the quality of the milliampere meter coil....

Ethan,
Since I published the article “Preamplifiers: keys to mystery” I received many emails from my site visitors asking about Lamm prams and questioning my remarks in comparing what I said to “data form other sources”. Some people disagreed or sur...

Here is my proposal for an ideal horn system. The concept derives from the really of the horns as I know them, the available park of the drivers, the drivers’ real capacity and from… everything else that I might comment upon if you would not figure o...

Chris, I did ask myself the same question: perhaps my given PTR9 is demagnetized. I called the last night to the owner of the tweeters and he said that he uses them for 7 years and they driver should be fine. He also expressed a lot of doubts if the ...

It was after midnight and I returned from my urban Saturday supper. A pair of the recently born “Melquíadeses” was sitting in the mid of the room, glowing and asking: so what? A sudden necessity of a radical audio sadism attacked me and I...

Hi,[quote user="Romy the Cat"]This subject of digital crossovers became quite popular during last few years and many audio-people give up and go for a simplicity and painlessness of digital crossovering.[/quote]Well, digital X-Overs would appear to o...

[quote user="Romy the Cat"] Make an experiment, and I will simplify the case quite assertively. Take a typical compression driver, cross it at 800Hz, second order and load it into a proper contemporary horn (Tratrix or JMLC) of 300Hz. Listen that hor...

Wow, where did you see a 1kW
amplifier that is able to produce bass that does not make you vomit? Also, why
would you need power like this. If you go with 15” high sensitivity driver,
then you would need 20-30W max. Do not forget that your objecti...

Ok, let dive a little bit further into my examination of the subject of Lamm ML3
What is important is to undusted that my view less targets the Lamm ML3 but rather it targets the ML3 as a representative of entire class of amplifiers. When I to...

[quote user="nl"] I have used Russian high-gm tubes like 6C45 in amps before, including single-stage designs very much like Romy's single-stage Milq. These have many attractions. However, in my experience it just didn't have the tone. Jim de Kort of ...

A six year ago or so when I played with different compression drivers I bought a pair of Dukane 5A540 and at that time I was not able to find any information about them. Nowadays I was pointed out that an eBay sealer “ bayleafs” actions a pair of Duk...

A recent article examined the capacity of the optic nerve to process visual signals. Based on the number of neurons in the retina, etc., an estimate of less than a megabyte of information was found, which is surprisingly low. This...

The “best midrange comes from compression drivers”. I see somebody like Haralanov would be very much opposed to this comment. The irony is that I would be opposed as well to this comment. I would say that the best midrange at over 107dB sensitiv...

what is audio ?
Audio is our reaction to sound , if there are audiophiles with different reactions then you may convince yourself Audio quality is relative to listener.
I think it is not true. The real quality exist itself .
