Chirag, First off all you have to define what do you want from them. If at this moment you’re looking for something within $700 then very next year, when you finish you medical school you will be searching in very different price range… :-) Now a lit...

Despite the tremendous popularity of the single-ended amplifiers have a certain group of audio people, let to be honest: the SETs do not sound REAL in audio people’s listening rooms. I was in many of those listening rooms and have heard many best SET...

I would like to think a little about the monitors. A monitor is kind of bogus name but useful. I usually call a loudspeaker that is not floor standing as a monitor. Sometime they called bookshelf but I hardly image any loudspeaker on a bookshelf…

I am kind of semi-evaluating a power amplifier now and think about the following: there is a correct relation between harmonic content of amplifier and it’s dynamic aptitude.
I have heard many amplifiers that run across the dynamic range with a tre...

[quote user="morricab"] I guess I view absolute tone a bit differently than what you describe. I think that each real instrument or person (as in singer) has its own "absolute" tone….[/quote]
Actually when I was taking about “absolute tone” I ...

My first impressions a about the “differences” of field-coiled derived form the time when I ran the Telefunkens war time drivers but at that time I had no reference how the same driver would act with permanent magnet. Also, the Telefunkens are the re...

Hello Haralanov,It is hard to talk about sound, and define points: this is why the post is so long.Most systems I have lisitened to that measure a flat response have exagerated high frequencies and usually the midbass is a little shy, this might be ...

[quote user="cdwitmer"]I'm probably revealing my ignorance by even asking this, but I'm curious to know if a field coil ribbon tweeter could be practical. It occurs to me that if one could be made, it would be a lot safer since it wouldn't be a black...

Make an experiment. Take any of those contemporary “highly reputed playback systems” and roll of their HF and LF unit you reach gramophone bandwidth. You might narrow the bandwidth with electric (LC) filers or with mechanical filers it would not be r...

[quote user="Jorge"]Sometimes it is not so much as adding color, but taking it away. Most cheap cone drivers will exhibit a loose sound, so if you want to get the cellos more clearly, you need to get some meat off the bones or they wil get lost...

Hi Gera"Has anyone done this and what were the observations of comparing different topologies."I have done just what you propose, I tried the JBL2490 compresion driver with a 3" mouth in a 110 hz horn well made, MDF round tactrix horn, it goes ...

Guys,
You really misunderstood this CD. This is just a compilation of GOOD MUSIC well performed and interpreted and it has nothing to do with audio. For instance now of my compilations CDs I ever played on my playback. Those CDs are good enough for ...

This is very interesting observation. I am in away envy that Petar went for a set of large woofers (4x23”!). This is the way to go! Unfortunately I did not experiment with it even I had the drivers and means to do it. My problem was with the fact...

While the APS guys trying to figure out why this unit can not handle power (which more likely involved a phone call to China :-) I decided to give another try across everything, repeating my last listening, this time in relaxed environment with diffe...

First of all thanks to all who assist me with this project, including those who did not post here.
Jim, Electraprinted Jack is great guy but he does not believe in exotic cores, very unfortunate because I like to deal with him.
Jessie, you are righ...

[quote user="Romy the Cat"] The S2 has own very idiosyncratic upper range with own helpful resonances injected into sound. I feel that that original metal suspension diaphragm does it bolder and more aggressively then the plastic suspension dia...

[quote user="slowmotion"]I don't understand what you mean here, Romy? To me "live" bass ( like when listening to an orchestra ) is much more dynamic than any reproduced bass I've ever heard. Also if listening to a real contrabass in a normal listenin...

It is not about Dynamic Range per say but about dymick differences that I feel and that I care with good ULF he effect of rising of acoustic and tonal pressure is instant, very soft but absolutely instantaneous. Live music has feel like literally...

We had this exchange with Christopher Witmer, who lives in Japan, via the AA about the new driver form some small Japanese manufacturer. The dirt who runs that form has deleted the whole development. Hm, people wonder why for years I have a vocal and...

E-v-e-n-t-u-a-l-l-y!!! Eventually the new “fundamentals channel” horn sounds as it should being incorporated in my Macondo! The key was the second order. I really never drove compression drivers to their 500Hz as I always used upperbass h...

Ok, this is probably the most important section as besides all positive changes that PP2000 does to sound it does this one, the one that I call “softness”, and the values of this “softness” have to properly understood and interpreted.
The “softness”...

Rakesh, during the last year, there were some very important moments in my own realizations about the methods of low frequency reproduction. I totally abandoned my Scanspeak bass modules and now they are resting in my garage. I intentionally have my ...

All that I will be saying are the subject of my own experience with horns and my personal observations. You shouldn’t agree and most likely you will not. That is fine with me. I have lot of reasons behind what I will be saying and opened for some cla...

Well, you can’t use Gogol Suite as some kind of reference in term of gain. The Gogol Suite was record by Pope Music at very high dynamic range they have very little compression. It feels like very soft volume recording as a result.

user="Daniel"] I need dynamic impact. I've been playing in bands for
about 20 years and I yet have to find a stereo and a recording that gives a
drumbeat close to the real thing. Cymbals are mostly dissapointing as well.

[quote user="RonyWeissman"] The HF sound is very quick and weighty , which can be quite nice on classical guitar for examlpe, but the tone is not clear enough, meaning for example cymbal attacks don't have enough metallic ring to them, nor enough blo...

At CES there were Viagra-junkie sized power cords everywhere for $5000. Around our room were $10k and $20k speakers that sounded like a wet jukebox. It was the land of delusion.Value per topology is one way to measure but let's instead start with a p...
