[quote user="Amir"]I am not expert and my experience is limited but What I think is Macondo could outperform other horn systems in right setup.[/quote]Soundwise, my Macondo is a very interesting thing although Romy's may well be somewhat different, I...

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...

Yes, to “voice” the DSET is tricky and requires a lot of listening experience, or more accurately saying – it requires to make a lot of mistakes and understand own mistakes. It is not difficult –juts require patience. Still, if one “get” how DSET sou...

My objectives when I wrote my initial post were not to knock the Herb Reichert’s design ideas but to demonstrate that DSET topology make most of Reichert’s views not applicable or even irrelevant. So, my post was not against Herb but rather to advanc...

Continuing the thoughts from the post: A powerful full-range SET? What a bogus idea! What I would actually would like to see is the industry not to furnish idiotic loudspeakers with granite drivers and then trying to push high power SETs to drive the...

[quote user="decoud"] Romy, can you be persuaded to post a sketch of what you think the optimal 2 channel Melquiades circuit would look like? [/quote]
Decoud, I do not think that there is such a thing as optimal DSET. The entire concept of DSET is a...

[quote user="Romy the Cat"]So, Teflon, I do not think you got what I meant. SET has no 'topological limitation' because exists DSET. DSET is free from any, even theoretical limitation, of cause if you prepared to deal with price and power demand...

Actually my wish for DSETinisation of Gammas has nothing to do neither money nor with Sound, really. The Audio-Morons™ buy and sell audio, and particularly those who are in the $200.000 bracket not because some specific sonic accomplishments or utili...

KOTriode, this is not the subject of this thread but I would like to point your attention to one aspect. From one side it looks like you with some kind of special pride talk about your Tango output transformers. From another side you are stupid enoug...

[quote user="rowuk"]I have experimented
with SS/SET and now DSEP for ceramic magnet horn drivers. I will agree that
ceramic drivers with SETs that I have heard being suboptimal, but after a year
of DSEP, at least for my use case, I am quite conten...

Yes, the second DSET is still not biasing properly and I cannot find enough consecutive time to look for the fault. In the meantime I've got a couple of minor side projects off the electronics bench, and started thinking seriously about preamplifier...
|
|
Yes, my DSET is fundamentally the same as yours with 6 channels, three fullrange, 1627a for Channel C. The largest difference is probably that my DHT channel has its own B+.My preamp is quite different though, being a hybrid based on 10y. It has a ...

[quote user="Gregm"]Actually, that could be a viable commercial product: a "stereo am"p allowing for four channels. One hi side, one low side, per channel.Any moron purchasing this could be stratosphrically happy flabbergasting his pals by "passively...
|

If you are in DSET environment then do yourself a favor and build into your DSETs a mechanism that would allow you to monitor the gain of your channels. It might be in real time or in a special calibration mode but you will need and. If you do not in...

After finishing my left 6-chennal Melquiades and putting amps and Macondo back as it was intended to be I was expecting that it should be “better” but I did not expect HOW MUCH better it might be. Many aspects of sound are more interesting now,...

[quote user="decoud"]Still partially wrapt in mystery, but here is potentially the first SS DSET:http://www.firstwatt.com/sit1.htmlI say potentially for that is not naturally Pass's direction, but each monobloc is designed to be tunable to its specif...

The 185+W into 1 Ohm is not a lot indeed but I do not understand all of those simulations and I do not know how the distortions of simulations affect the actual results. N-set, when you are mentioned the “Romy's constraints on a powerful bass SE amp”...

[quote user="jessie.dazzle"]Upper Bass : Frequency range between 100 and 500Hz – Driver loaded into a 120Hz straight horn, driven by DSET dedicated channel. Mid Bass : Frequency range between 40 and 100Hz – Driver loaded into a 45Hz straight hor...

Yes, I knew that you were not accurate with your assumption that MM cannot run 75mSec offset.I am not a big fun of this method as no sane person would use MM cartridges. However, what I find is very attractive in this phonocorrector is to employ SOME...

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 ...

This post is a logical continuation of the post: My “radar of sensations” about the “good honk”:
http://www.GoodSoundClub.com/TreeItem.aspx?PostID=15814
I wonder if any manufactures would be interested to undertake bass DSET proje...

Nope, I am not familiar with sound or applications of this tube. It is indirect heated beam tetrode – why would it be any different from the whole family of beam tetrodes? From my perspective it might be interesting for ULF DSET solution as it has a...
|

I know you do not want to do it, but it is a shame not to do it: actually manufacture a version of the Macondo with an integrated dset, cut down enough (say three channels) to make it feasible while still demonstrating the advantages of the dset idea...
|

I imagine the resistance to the DSET concept does not come from idiocy - Lamm may well be steeped in vanity and avarice, but he is certainly no idiot - but from resistance to combining amplification and loudspeaker in a single, coherent, monolithic s...

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 ...

It took a LOT of time in CAD using what I had learnt from building the power supplies and then adapting it to match the requirements of the rest of the system. I have decided to mount the DSET on the horn stack and direct connect the speaker cables....

I went today to Srajan’s site check the news and saw the following:

Do I remember that a big part of Romy's choice for a pre-amp was based on the specific needs of his DSET Milq, with it's inter-stage X/Os? And do I remember the Placette Active Pre-amp has consistent, fu...

[quote user="jessie.dazzle"]While reading of your progress on the 6 channel amp, I was thinking ahead, and how I might approach the building of such amps as separate projects for each frequency band (separated physically as well). In my particular ca...
