Looks like the SPL headphone amp thing-ee is mostly about generating/getting sound effects for/from headphones. At this point, I think what I want is an "intact" signal at unity gain going to each of 5 channels. This should mean that the blended, c...

N-set, at this point I am under impression (not conviction however) that a hybrid with some kind of harmonic correction circuit can do the job but spend much less blood. I have to admit that the best hybrids that I head had (Lamm M1.1) no where remot...

What is the "reverse engineering" version of an SET circuit that would accomplish - in terms of audible results - what you want? The reason I suggest 3 stages is only because I see a gap between required input and necessary output for the proposed d...

I usually go with turns ratio. The ribbon tweeter has I
think x175, the 6C33C full range is 10x or 12x and 6C33C in DSET is whatever it
was – it is kind of irrelevant in DSET setting. The YO186/PX-4/RE604 I think
has x25 transformer. My loading nu...

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...

Some Hypex-type sub amps with ULF X/Os have high level inputs. Maybe this is a way to feed the thing from your DSET, if this is a goal for you? I think most of this type X/O and amp combination have an input buffer, and most of them have 180/variab...

it has a like brother Ecoflow R600. Somebody might try them for audio...[/quote]Romy, I have a Delta here, but do not use it for audio. Would be easy enough to ...

user="anthony"]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 18Hz
once room reinforcement does its magic. One of the few benefits of a
small room. [/quote]

Audio-hoarding is something that I am very thoughtful about. Admittedly I have quite a bit of stuff in storage but it ALL has to do with the current Macondo/DSET build and will soon all be in its place. I don't even own the speakers that I am liste...

It seems like I should just abandon the idea of using the Druids... and trying to get some sort of coherent integration with my WB-Chimeras (acting as the lower- and upper-bass units)... and running the whole hodgepodge with totally different amplifi...

Thanks Romy. First the amps will be finished and then the Upperbass horns. I may even get the second DSET ready to go upstairs this weekend assuming everything goes well and nothing goes wrong. Will be nice to hear what I have at the moment in ste...

[quote user="anthony"] Briefly, I tried altering some operating current on
the valves and now have a better understanding of how DSET can be used to shape
the sound. It is one thing reading about it but another thing entirely
when you turn a knob...

Romy,My DSET amps are still open (no top plate) so are fully ventilated, but I have left vents in the top plate around all of the valves and installed two computer fans (running very low speed) that push air from the bottom and out the vents on the t...

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...

I’m not convinced at this point that it is good – I need to see it more in context of everything else - but the initial results are very promising. What I do now, I keep the compression Fane 8M in horn but I very dramatically increase dumping of it...

Romy,Interesting video. The first thing that came to my mind when you were talking about HF colours and the "clean" RAAL Waterdrop tweeter, is perhaps adding colour to the RAAL. Instead of blanding out the midrange S2 and injecting HF colour with t...

The interesting thing about the Bottlehead people is that they are pretty good guys. "High and outside" is I think Paul Stubbelbine, who is an expert at mastering. He remastered my girlfriend's last album. I was very impressed. His ...

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...

3 weeks, eh? Vs. how many years for functional DSET? Next, a great 5 cent cigar!Same questions about decoupling a phono stage from the split, re-setting the output impedance, and doubling the output. Where and exactly how does one split and boost the...
|

*** … unless you are saying that the preamp Zout will possibly change the DSET filter phase somehow? Yep, this is exactly what I am saying. Look the impedance of your preamp is factored in the source impedance of your channel’s filter. The argument...

I do not think that I might use an equalizer in normal sense; I do not need the full flow EQ option. What I might find useful on some case is to have 4-5 fixed curves and it would be pretty much it. Hypothetically with Macondo and DSET I might write ...
|
|
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...

[quote user="decoud"]Hi Romy, I imagine the coupling cap in the full range melq acts as a first order high pass filter: is there any reason why one could not lower its value to raise the cutoff to a level one would otherwise redundantly need a speake...

Zanon, you seem to feel that RTA has some intrinsic value. In any case, in terms of results, I think you already have a sense of where this is going. If you are bound to use your present speakers in a room you yourself deem too large for them, t...

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...
