[quote user="haralanov"] So the tweeter is always needed. The bad thing is it deforms (in 99,9999999999999999999% of the cases) the perfectly round audio window, formed by the midrange channel and "pull" some notes sometimes at its axis. These are of...

I was thinking about this when posting on the "deathbed audio wisdom" thread, where I said that to accept that there is a distinction between live performances and recordings, make peace with the notion, and derive the greatest pleasure from both bei...

“…stop by and bring some of your music….” – how many times we hear when we invited to listen someone’s playback. I am sure all of us have a selected favorite recording to assess playbacks and I would like to share some of mine that I have been ...

HI all, my first post, although have been reading for a long long time and have contact with some members. Great site.Wanted to share with you my experience with a PurePower order. and my huge problem... I have read terrible things here before but I ...

[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 ...

It is nothing to do with Wisdom. It is my principle of application of “cost” as a common sense design tool. I do not bitch that Duelund caps are expensive. I just try to find a rational solution for using them that would embrace their price. My ...

I am not a big fun of Dvorak 9th under Ancerl. I’m not big fun nether the orchestra’s balance nor the recording quality. Anyhow…
I do not think that that you need to worry PH-77’s accuracy of curves or the comfort to switch them. It looks lik...

[quote user="HookEm"]The reproduction does not seem natural... too far away from what I would hear at a live event (e.g., female vocalist). Sort of bright and fatiguing at times. I may not be using the proper terminology to describe it, but I do...

[quote user="steverino"]FWIW I got my own PP 1050 a week ago and am pleased with the sound. It is the first active device that sounds as good as or better than my jury rigged passive filtration. Thanks Romy. As for chaining devices, I tried plugging ...

I keep thinking about the strangeness of my phase inversion.
I still do not think that it should be this way. My leading explanation is because
I did not implement the crossover precise. If the crossover called for let way
63mH coil and 795uF cap ...

I was wondering what the noise of stereo signal come into FM and are any ways to reduce it? Naturally we get out stations in mono mode with practically no noise at all. The best tuners more then 85dB signals to noise ratio – that are very high number...

Keeping harassing different people bout the most interesting options for multiplex decoder for my Rohde & Schwarz EU-6201 I was wondering if it makes sense to me to use the Rohde. It is a very good tuner but it is not necessary result in better s...

[quote user="Romy the Cat"]Well, it might sound as a heresy to you, but I personally
consider the impedance curve is a bit irrelevant in this application. In this application
you need to care only about only 2 things: if you have enough power in yo...

Yep, it looks, like very close to “it” design-wise. http://www.studiomaudio.info/loftinwhite.htmlIn the way this amp is one of the manifestations of Loftin-White DC-coupled but it has some own things. The driver stage is the Melquiades Tube to k...

[quote user="jessie.dazzle"] And Ok, maybe I don't have all the filters dialed in, and the DPOLS are like a dream to me now….[/quote]
And with 1600 pound per channel you might forget about the DPOLS … -:)

The system is still very much a work in progress, but I have come to the conclusion that the concept as such is very, very good. It's only up to me to make it sound as well as I know it is capable of. Making and fine-tuning the crossover might take m...

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...

I never knew that it will be so much fun. As I started the basement cleanup project I did kind of remotely conceptualize that I will try to make a winter pipe smoking place. Instead I discover in my house a new listening room that I have to tell you ...

Steverino, I spoke about it a few years back when I was just introduces to the idea of double-conversion class D regenerators. There are ton of them out there. I did tried two of them they were not good but it does not mean that other will not be goo...

Most here are probably familiar with the fact that A/B "blind tests" were popular in the early days of "audio", where listeners seemingly could not distinguish between live sounds and electronic "counterparts" issuing from behind a curtain. Today we...

[quote user="rowuk"]Maybe a lot of what Romy or Harlanov hear is determined by what they have conditioned themselves hear in a specific way? Maybe we are all victims of our own "conditioning" and need to address this first? What IS amazing to me is t...

Actually I did have it is past. At that time I used a low-pass filer on my upperbass horn. It was 103dB sensitive driver of 16Ohm, highly inductive, and I needed somewhere hear 800Hz, speaker level, the first order. Being an extremist I got 3mH coil ...

Hi,[quote user="Romy the Cat"] After some experiments and still being dissatisfied with the HF I ended up consulting with Dima. He spread me a theory according to which the HF was killed by my coupling Silver Mica cap. All my arguments that sil...

[quote user="Chirag"]Outside of the already constructed bass towers, is there a reason you are looking exclusively for 10" drivers? I have heard a pair of stacked 15" Lambda's on each side supplementing/providing bass to lower midbass under som...

Thanks, Chris.
Dima I discussed today many imaginable scenarios. Initially we thought drive a single 6C19P from MF channel of super Milq. But it has some negative consequences… Eventually we decided (it is not final decision but the final with 90% ...

The good thing of having own dairy-oriented site is that I can look at what I was positing during the year and to have good grip of what was going on over the passed year. Still, although everything is on the surface, I would like to bring up few bri...

Actually I was wondering what the hell you were talking about what you were bitching that the ML2 socket can not handle 6N6P first. Ether you changed over 10.000 tubes in there or something else was wrong because the ML2 sockets are fine (except the ...
