Jessie,
A few hints. If you are moving from Parsifal/Encore and LammM1.1 world into the world of SETs and Horn then do not be in hurry to commit yourself and do not create to yourself artificial addictions.
When I talk about artificial addictions I...

RomanThe main point is that I like the Bass SET aproach with LF capable transformers and have a potent SET to properly drive whole band and take the amp out of equasion in the future when I learn how to build horn speakers. The system I have is an ac...

No question in my mind that the tubes themselves contribute to the sound we get from tube-based systems. Funny how I go to such lengths to get "quiet" tubes and use dampers even as I realize that even the quietest tubes are doing their bit to/f...

Daniel, if you have start, the igniting voltage, on the gas tubes 197V then it is perfect. If the tubes do maintain stable 150C then leave it as it. Each of the gas tribes has own stabilization voltage. If one of them has let say 148V and another 150...

Well, this methodology would about sink the contemporary hi-fi "industry", wouldn't it? Now try it again into a typical reactive load!Apart from "spec-driven" design, perhaps the determination to milk the the most possible "power" out of a given cir...

Well, I would say that “something is wrong” as what you report it is not how it shall be. I had my doubts about the rational to use 6C33C in direct heating coupling but the “danger” in direct coupling uselessly coming from the plate of the driver...

Back in the 90's i bought a pair of Aura 1808 woofers and made a set of 24 cubic foot corner enclosures 1 1/2 thick, crossover at 100hz, close to 300 pounds, way over built enclosure with a baffle on the face of the enclosure that i could remove. I T...

Well, I may be one of the dummies here, but there are several things that could be viewed as "wrong" if sound was the primary goal:1) 95dB speakers and SET amps2) SET amps instead of DSET3) components assembled without a sonic goal - rather only comm...

N-set, I could not raise the attachment. It has literally been years since I saw the Axiom (SET) circuit, but as I recall, it works with (tube!) diodes coming and going, to maintain balance, isolation and stability in the face of a classic "stacked"...

[quote user="jessie.dazzle"] Back when Fane were still in business, I ordered a pair in 16O (I don't know if there is a theoretical best choice between the two for horn loading... Any thoughts ? However, the 8O model will require a smaller coil in th...

Adrian,
what do you see fundamentally appealing in the symmetry of the differential circuits and what the relations between Sound the symmetry? Not to mention that the perfectly symmetric circuits do not exists. I’m very far form the people who coul...

Romy, Some very good points here... if I downloaded the correct schematic from your site for the 6-channel Melq amp (also has the term DSET in the title) then you have created a 6-channel SET amp with built-in crossover points. Your first ...

Glad to hear your bigger family is doing well and that you are making good progress on the room.Why not try a quick test. Try connecting your laptop to the big system, put the laptop a few feet in front of you and watch a movie or a concert? That wil...

Thank you for your answer.If I understand well, In purpose to do something realistic and good sounding. I should use at least 2 amplifiers (one for high frequencies and the GM-100 amp for low frequencies) with a tubes active filter at the inputs of e...
|
|
Glad to hear you've found a short cut. Of course you don't want to run the Auras too high, but the IB should allow them go go higher than they might in a box, and it should also improve the transition to the bass. If you decide to go SET it might b...

You go a head and stroke your minion Romy. But the few that have some brains will see threw your bullshit. You rap your horn skin in fiberglass with some 1/2 strips and if you get it to resonate at any frequency between 40 and 180 cycles, I will pay ...

[quote user="rowuk"]This is one of the aspects of being a "conductor". Very immediate sound, little early reflections or concert hall - everything is "overly" dynamic. When we compare this to being in the audience, each instrument group behaves in di...

Part of setting up a system is listening to both channels independently, they measure the same and sound the same, but individually with a lower volume and punch, and of course no stereo effect." the audio window should get larger and larger, unti...

There is a very interesting subject in Language of Audio – the filter slope. The filter slope is well known aspect in the audio and here is nothing new could be said in there but there a twist in the filter slope. If we are talking about multi-chann...

Oh, good, it's you, N-set. This is a COOL idea! Maybe you can set me straight.The way I see it, to be significant, the full-spectrum sound recording alone would pose its own challenges, for sure. And what are the parameters for linear measuring, a...

Paul,As you know I am also a believer in the hard tracing, and have likewise consistently rejected all MC cartridges due to the lack of realism and their inability to penetrate beyond the most superficial layers of audio splendor, though these they d...

In regard to moving coil cartridges, I would say:1. This may simply be a symptom of electricity variability. I would listen for a few days and see if it improves.2. Cartridges not used for a while need to loosen up a bit in regard to the suspen...
