Yes, I totally agree. In my old place, I had the Druids working in FR with the Berning Siegfried 300B, and they sounded exactly as you say.But I'm hoping that the Berning will cope better driving the Druids with a high-pass filter set to around 150Hz...

The Bass OPT's for my DSET have been wound. We have come back to a 1000R plate loading and into 1R the 6C33C grid clips at 9.36W and 5.8% distortion. The -0.5dB points at full power are 5.9Hz and 5kHz.A nice result really, and about where I thought...

Here are the basics of the 6-Chennal Melquiades DSET Amplifier complete, without secondary features.

i have vitavox S2 and also altec 288c.i am trying to source the fane studio 8m,just missed a pair by 1 day on uk diy.until i get the fane and make a horn for it,i will use altec 515c in vot.i also have jbl 2405.yes i will definitely build the full ra...

If I try Trapped Horn then it will be ether 90” toll or 108” tool and as narrow as possible. I am not looking for “reverse engineer the tapped-horn and refold it in a different manner” but rather to somebody who know what they do to design the right ...

[quote user="el`Ol"]I heard the Orgon and I didn`t notice any electronic colorations. The midrange of course doesn`t have the sweetness of an SET, but is the most realistic I have heard from a piece of hifi. The two things on my wishlist would be mor...

Well, how many absolutely transparent passive crossovers are there, line level or not? For me, the question is the other way round: if a passive crossover at 1 kHz can be done with good quality, I can "get away" with a single amp for the region over ...
|
|
Bill, of course I supposed the DSP-free sound would sound better than processed to me, based on my experience. I just wanted to know how you felt about it, when it was put like that. I went to big SS amps despite I prefer the sound of small SET amps,...
|
|
Yes, sure, conceptually it would look very interesting to bund drivers and DSET amplification into one entity. I think if I use some kind of SS SET amplification then it would be a good idea to make amplification in the shape of the attachments to th...

Hello,
I've never had an SET amplifier in my system. Having high efficiency horns (106 db on average down to 100Hz ) I have tried a number of solid state and tube amplifiers, and I am aware of their sound in my system. ...
|
|
I have been amazed that some people are not able to hear different operating points. And I have likewise been amazed when some folks liked the sound of their FCs with double the stock-design voltage. Of course I do not "recommend" that anyone vary F...

Yes, you might, though I

Just the symptoms caused by the bad electricity, tons of tubes and other parts in various stages of decline, pins/sockets/connections, along with analog and digital source issues is the stuff of madness. I am so happy when everything works...

[quote user="guy sergeant"]A few months ago, iirc, you linked to a Canadian? amplifier which seemed to be made as or perhaps could be applicable for DSET use but I can't find the link. Can you remember where its is (or what it was called)?[/quo...

While my Obbligato caps are traveling from Asia and instead of finish my MF amplifier and listening it I am blowing up my steam about the amp at my site there is a subject that I would like to share.
Melquiades MF DSET is made to utilize not o...

Suddenly a strike of geniuses hit me and I found a way to extend the bandwidth of Milq MF channel up to the standard for DSET extended level. I do not know if I need it and if I have any subjective benefits but I found that the solution is very elega...

Romy, thanks for the explanation.
I was not sure if you still kept an eye on that thread Romy. As far as I know you need to be logged in to view the images in the diy threads so I will post a couple here to show where...

[quote user="Romy the Cat"]Make the full-range and then you will see where you are.
Still, I feel that for MF channels it is beneficial for do with a good DHT output
stage instead of 6C33C and perhaps it is a good idea to use DHT driver as well.
S...

[quote user="Cosmos"]Indeed it took me a very long time to decide upon regulate or not. I ended up with regulation option to save some chassis space and weight, otherwise I would need at least 10 kilos more and 30% bigger space that would make the wh...

Thanks Romy. To be honest they look better in the flesh than I had thought they would so I am very happy with them. I think I'll make the steel order today so I can finish them at my leisure.If I end up with 8 drivers a side, which is what I am pla...

I certainly hope more people will get going on the different versions of the Melquiades amps so I can learn more about them. So far, this site is a crash course! I just hope everyone is paying attention when thye read here, over and over,...

Idiocy aside - and there is enough money in audio to guarantee not all of the pople in it can be idiots - why is it that no-one seems to have come up with a commercial dual channel SET solution: one channel for HF and MF and another for LF? While not...

Dragged the Delta inside today and plugged a single DSET into it. Startup went ok but I was a little worried when the second stage caps started filling and Delta momentarily spiked at over 2kW draw. Once the amp was fully started draw settled at 33...

No, I wouldn't dream of driving my SL600s with the Berning. My understanding is that with their low sensitivity and lowish impedance, the SL600s need current. The Rotel is capable of delivering 150A into 0.1R (for short 10 microsec bursts), and seems...

[quote user="Romy the Cat"] There were some educational for myself observations made, in some way saying something about this specific DHT, in some way saying something about Melquiades’ single stage version and the Melquiades’ full-range two-stages ...

[quote user="Paul S"] I think that bit of marketing hype must derive from Lamm's ML2 (& 2.1?) "Operating Manual", which says: [the ML2] "Maximum Output Voltage" "with continuous sine waves, at 1kHz @ rated line voltage" [is] "(blah, blah, blah), ...

The bitch is, it takes so long to work through everything in your own system; but that's basically what it takes. If you go DSET system, like Melq, you may well be years away from getting it all up and running. And even once you are happy with your r...

Macondo is no magic bullet. Sure, Macondo/DSET is put together in a way that it's components need for optimal operation, and when "used as directed" the performance is phenomonal, but it is still prone to room integration and poor setup so will like...
