Thanks Romy!I went with two tiers as I do not have much space between the speakers and the side walls as I have a 2.5M cabinet on the front wall.I named my amp Koshka as I always felt Koshka made a contribution to the development of the Melquiades an...

It seems ironic that the path to bringing the single-channel DSET/narrow band horn idea to market would invlove traditional marketing per se as much as the melding of evolved listening with cutting edge technology. While there is rote work...

[quote user="Paul S"]Yesterday a nice fellow drove off with "my" Lamm ML2s. Now it is really sinking in: How will will I find anything else this good, along with more power?These amps were like a PhD in sound, what might be done with hi-fi. Yes, I ...

[quote user="floobydust"] 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. Yo...

[quote user="drdna"] The subwoofer still needs a substantial power source. Right now it is being driven by a solid state amplifier. It would be interesting to see what impact the SET could have here if any.[/quote]
I see, I did not know that ...

I do not exactly comfortable with oxric’s preoccupation with “parts”. Yes, there are some amps that invest a lot of attention into parts quality – the silver winding in Kondo, oil caps in BAT, of silver foil caps in AN might be the examples. Melquiad...

Romy, that passing remark about 4 ML2s and DSET was not my complete thought on the matter. In this case the LF slaves would be topologically just that, meaning changed to suit the role of dedicated LF-only amps. If that st...

Still, I would like in this thread to stay with subject of advantage/disadvantage of DSET approach vs. better/expensive SET: "A DSET is better then an expensive SET" instead of turn it into thread about David Berning. Bernings certainly might be...

I am making steady progress putting together my DSET amplifiers. Life and work gets in the way but I am chipping away at it, taking my time, not rushing, enjoying it. Wow, it is a lot of work and an enormous task for my first complete amplifier bui...

Gera, there is already a LOT of discussion on this topic salted around this site. I suppose you do know, but a couple of things you said made me wonder; anyway, at the risk of offending you (and not meaning to): "SET" means "single-ended triode" (as ...

[quote user="morricab"] You are also right that to get everything you want from an output transformer requires a VERY expensive construction and top materials. However; even an expensive transformer is no guarantee of success. [/quote]
Sorry t...

[quote user="drdna"]You want a suggestion for a good 2A3? Get Ricardo Kron's (KR Audio Enterprises) KR 2A3. Very rugged, overbuilt. There is no comparison between this tube and all other 2A3's, and I tried many of them. The sound is more dynamic, the...

[quote user="Romy the Cat"]When you are taking about “caps at higher frequencies”, then what do you
mean? The line level, the speaker level, the line level between? Do not forget
that a RL filter is always preferable over C filter.[/quote]It was re...

[quote user="Paul S"] The "calm HF" effect is something I have long sought but seldom experienced from repro, and I have blamed the amps as much as the ribbons. Mere HF extension is not enough. Hard to say whether the amp or the rib...
|
|
It is difficult to generalize but I will. As much as ribbons with each hertz down sound more and more unpleasant the low power SET amps with each hertz down in bass region more and more and more loosing ground. Ok, I am not taking about the real bass...

Here is another advantage of multisampling and DSET in particularly. There are many moments in amp that in one or another degree affects transients.The capacitive coupling for instance works fine but as long the amp sits in class A1. As soon amp hit ...

The more I get out and listen to other systems the more I appreciate Macondo/DSET mainly for the life-like dynamics offered. I am also sure that many of the people that listen to my version are unable to grasp just how dynamic the sound is compared ...
|
|
Yep, it is a lot of work and it might look like not well organized work but there is good part in all of it – when you will be do you will be done and you would never do it again. Practice shows that those custom tailored systems are made and then us...

[quote user="Paul S"] Too bad it has no "grunt", whatsoever.[/quote] I wonder why someone would blame type 45 tubes in lucking of grunt sound. This is 1.5W-2W that by the size of plate intends to be in HF DSET only. Are you driving you 15” woofer fr...

[quote user="jessie.dazzle"]Is this because of the way you are driving them?When testing my one completed mid-bass horn (AK151 into 40Hz Exponential with 8" throat), and powering it from an amp that drives everything from upper bass to HF, the output...

[quote user="Romy the Cat"]Tax what are you willing to accomplish by DSETing Avantgarde Duo? As far as I can see in any playback action and decisions it shall be a straight line of sight to some kind of objectives. What objective you have in your min...

I am very interested in your DSET adventure, and is trying to learn more about the application of adding crossover elements into SET amps. Looking at the schematic, I noted that you add first-order passive filters before the first stage of your...

Mark, what loudspeakers are you planning to drive in this configuration? The single-stage amp is 2W and the full-range Milq is 6W -7W. Anyhow, look at my replies to others in this forum. I always advise before thinking about DSET around Milq to famil...

[quote user="jessie.dazzle"] I don't have a problem with what Lamm has done in offering the ML3 (ignoring the price)... If I have a problem it is more related to how the product is being represented. Representations aside, depending on how it sounds,...

Thanks for this one Romy, very interesting...it sorta ties together several things that I have been thinking about lately. I guess I am lucky that the Bass Cannons can be run off 9w from the DSET bottom channel and from memory I get about 115dB at 1...

Romy,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)?...
|
|
Romy, does it not make sense to integrate the speaker and amplifier physically, given they are so tightly integrated conceptually? After all the concept of DSET essentially makes an amplifier bespoke for a speaker, so the only reason for keeping them...
