May I at least ass-u-me that you plan to high pass these horns? If so, go ahead and figure that in, too. In any case, just looking at 70', impedance is not the only number you'll be running up, and the last place you want this load is for LF chan...

After much consideration I desired to get my test crossover. I chose when for Velodyne SMS-1 that someone pitched at this site before. The unit has 6, 12, 18, 24, or 48 dB/octave low-pass filters that I need and runs up to 200Hz. I do not think that ...

To keep with Romy's spirit of sharing his work, I have attached a file of VER 1.0 of the DSET Power Supply. There are quite a few differences to Romy's published schematics but it is basically the same beast. You will notice a lot of power transfor...

Hi Romy,Great site!!!!I`m in the early stages of designing a horn system and have been unable to find any info on thesubject of boxing in horns leaving only the mouths exposed. Is there anything about doing thisthat would cause degredation in th...

The Sussurro has an unusually wide loading range listed by Soundsmith, ranging from 470 ohms to 5k ohms. It is possible that more recent models have a somewhat tighter range between 470 and 2k ohms but I am not positive. The capacitance of Soundsmith...

Looks like another case where clean AC wall power is demanded and supposed. Since they use triode output, I wonder if the "gain path" of the pentode is "wired triode", as well, or if they just want the extra gain to scrub in the upcoming RIAA; or ma...

Hi Guy, I know what you mean; this phono stage really should not work well at all. I mean, voltage doubler, 3 stages of 12ax7, feedback, cathode followers, garbage looking power supply shared tubes for stereo...mortifying isn't it! These ...

Perrew,
I would take RL filtration ageist C filtration any time and under any circumstance. If you look at the circuit of 600R LCR classic Tango filter

While the question was somewhat facetious there was supposed to be a serious point behind it. I experience a similar 'effect' with a linestage I sometimes use. It is quite easy to hear what this stage contributes and initially it is too differe...

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. There is an army of people out there who would swear by a complete transpare...

I got a forwarded email today containing the Lamm Industry’s release notes about their new SET amplifiers.

[quote user="Chirag"] It seems the 6e5p is driving the transformer directly. I've used various versions of even simple mosfet followers to good effect at the headphone level, but never considered using a speaker level transformer. Did you and D...

A few days back I posted the following post:

…proposing the parties of interest to play along in Milq vs. DHT competition. This interst derives from the following thread:

Well, what is interesting in the subject: if the Cessaro guy will ever go for the DSET configuration in his commercial products? I am not certain but it is possible that in DSET configuration it might be possible to overcome the accused shortcomings ...

Yes, Peter,
I know that in the Steinberg WaveLab use only Bob Katz’ metering system, still I thought that if they are cooperate then Katz’ Ambience Recovery might be available as a standalone plug-in. It is kind of suspiring that Mr. Katz was able t...

In the past there was such a concept of full-function preamplifiers that included MM and MC inputs. With time such devises die out and nowadays it is VERY difficult to find a full-function preamplifier generally and a good sounding full-function ...

[quote user="Romy the Cat"]Rakesh,I think you’ve missed the accent of my battery post. We do not argue abstract topologies but we argue the validity of topology in respect to sonic results. I hope we all agree that we do not exactly know WHY affect...

I am interested that Romy has found some interest in DHT amplifiers.
Many, many amp builders have used many, many tubes over the years, including many IHTs, triode-wired pentodes, etc. Japanese builders have used big transmitting pentodes driven i...

[quote user="jessie.dazzle"] Yes yes yes .... Lamm Industries is a BUSINESS... This is abundantly clear whenever I order tubes from them! [/quote]
Hm, I did not know that you use any Lamm electronics. In fact I just realized that I have absolu...

Well, Nerone, the differences between any tuners would greatly vary with signal, not even with the strength of signal but rather with the specific location and surrounding of a given station. To make the things conceptually right it wou...

I kind of understand what frustration some audio people have when they hear that Daniel Weiss claims that he designs his equipment without any listening. I find those frustrations are from wrong reasons. It is funny that audio people believe that...

[quote user="oxric"] But I take issue with your often used accusation that other audiophiles are using faulty methodology and their conclusions are null and void. I do not think anyone has ever questioned this stance of yours and the more you mak...

I already have some PY500 (it's a sign =))) ) and I have 836 too.I read about Malquiade amplifier threads.So it seem peoples on this forum like horn speakers (I love them too) and are looking for fast transient response, it's exactly what I like.But ...

Hi Romy,
Could you explain a little more about the amp? If I understand you correctly it is a 1 tube stage with solid state (Mosfet or Bipolar??) output. If it is Mosfet then it is likely to be running without negative feedack, is that r...

Hey Cat,Well..my first question would be regarding the application. The big Melq tube is already doing the bass towers...is it not enough current? And wouldn't a proper class A 100w amp with its low low efficiency require something like 1...

Another interesting thing: why not a lot of people make the single ended hybrids? I understand that single ended output has very low efficiency but still: it is only about the heat dissipation. I have seen some single ended SS amp. There was a strang...
