Over the course of the last year I have been gently harassing my transformers-savvy surrounding trying to evangelize them into amorphous core. They stubbornly and perhaps stupidly resist. Some of them not…

[quote user="Romy the Cat"]Even though quantivly and structurally bass is correct but it is not what I am looking. [/quote] Last night I got rid the SMS crossover. I built in the 28Hz, 12dB per octave crossover in the Yamaha B2 amp that I use f...

[quote user="stuck.wilson"]In this thread, you previously said--
12) If a filter requires a phase inversion then it is preferable to flood crossover point with amplitude and do not invert phase.
What exactly do you mean by this and how's it work?[/...

[quote user="drdna"] Honestly for now, the character of the tuner is unobtrusive enough that I notice mostly the problems I have with the preamplifier and the electricity. However, I would be interested about what you had thought at this point to be ...

Welll, you still did not express yourself what are the sonic verdure of DHT from your point of view. You are not obligated I juts proposed you to do it if you feel that have any observations on the subject.

How lucky I am! The Melquiades bass channel at full throttle gives me just enough gain to power my Midbass horn to the reference level of my MF channels. That is truly a very lucky thing. The biggest dilemma I am thinking now is type of the filt...

[quote user="Merlin"] I have … yet to hear a bass unit that can provide the low end quality whilst still allowing a first order slope. Unless we are happy to accept copious quantities of 2nd Harmonic of course. I would love to know of one.[/quote]

I has been thinking the whole evening about the subject of
the ULF hardness I was experiencing today and here is my leading hypothesis. I always
was pitching that a sharp order filter is a barbaric thing to do, particularly
at LF. Still, here I am...

Roman,[quote user="Romy the Cat"]Nevertheless, if that bass was truncated between the stages then the devastations are way more severe. [/quote]That may be so, however an LF response of less than -0.1db down @ 10Hz is what is normally called "ruler f...

I need to tell you that for a few days I been thinking about
what is going on with my channels. The measurements and listening clearly show that
I need to invert R and L lowest against each other but my guts keep telling me that
it is pure BS. The...

OK, after a few days to straggling with this damn tweeter I might report that the Water Drop actually made itself to sound civilized. It sounded somehow fine alone but it was a real nightmare with Macondo, I juts was not able to integrate it. I measu...

[quote user="nl"] Gordon Rankin of Wavelength Audio did a series of one-stage DHTs with a step-up transformer input about ten years ago. I think they were called the Mercury series. By all accounts, they sounded good, but of course had limited gain, ...

[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...

Stitch,
the only thing that you are missing is paying attention to the OMA advertisements and truing to recognize behind it any rational beside a pimp yearling own merchandise (in fact it is not his merchandises). I told many times before tha...

First of all it was quite interesting and quite educational. Second of all it answers no questions but rather creates more questions. Here is what I try to compile some my observations and thoughts on the subject.

Romy,
Please accept my apologies for my first posting on your website. I had only perused a couple pages and may have come to an incorrect conclusion. While it is human nature to lock onto an idea and dogmatically pursue it, those in touch w...

A few things I would like to say in context of Pham’s playback.
I will leave his infatuation with turntables alone – man like to collect turntables and he within his constitutional right to do whatever makes him happy. The problem that I see ...

Ok, I removed the series cap from the amp output and made it as it should be – pure parallel. To my great satisfaction the little “dirty inflictions” that I got in Vitavox are gone and now the S2 as clean as it should be. I presume in the former sett...

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...
