[quote user="vakman"]Thank you for your reply and honest feedback that there is no silver bullet.In the interest of trying to move forward, is there anyone in Sydney, Australia who has a Macondo based speakers, whom I maybe able to visit and enlighte...

...you've got to set it down on a table. My wife also gave me this book for Christmas, and I agree with your value assessment. I cannot see anything like this being published again and it very much seems to be a labour of love for the authors. A c...

[quote user="Romy the Cat"]Anthony,
First, your measurements again the “appropriate load resistor” has very little practical meaning. The
drivers is a dynamic system that has impedance not resistance and the impedance
varies with frequency. So...

Today, I decided to measure input voltages that induce clipping in my operational DSET. I basically just put in place the appropriate load resistor, set the signal generator at a level in the middle of the bandpass and increased voltage until the si...

Romy, have you had any experience with Autoformer VC's? From what I can tell they could work quite well at the output of a preamp driving the DSET's, mainly because they lower the output impedance of the preamp as they attenuate rather than staying ...

...on the Placette. Biggest problem at the moment is that it does not have any gain and I definitely need some gain.What I have done is breadboarded a nice diy SS pre with 2x or 3x gain, dc coupled, current mirror, 100mA. It was started a couple of...

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...

Unfortunately I've reached out but not managed to make contact with John Hasquin regarding the spacer in the upperbass horn. I'll just have to wing it.I did finally manage to get a day and a half to make the second DSET operational but it refuses to...

...there is a degree of "sameness" with all sources into the Placette. It may just be the variac or the wall wart or both.
I talked with Guy back before I made the purchase and his recommendation was to use an externa...

[quote user="Romy the Cat"]However, over the years I have seen
that the low voltage adapter get weaker and impact the remote control functionality.
Also, the type of the low voltage adapter I used did have very profound impact
to sound, which abso...

Well, probably not up in smoke, but it is just not functional any more. I was away for a few days and came back to my room to find the Placette refusing to change volume or select a source input, so something is amiss. Perhaps something has been am...

...and it is a neat 1.5VRMS with zero attenuation. So with my -6dB it puts out 0.75VRMS, so not quite as bad as I thought. I will have to do some listening to try and determine whether -6dB is needed or if I can get away with less attenuation (zero...

I cannot find the Gorenstein version of Gogol Suite in Australia but it is available on Discogs and Amazon overseas for extortion prices. Streamed it from Youtube, not Gorenstien, but someone else, and it really made me smile. Listened to...

Rowuk, a couple of corrections, but I am certainly not arguing. First, the dac outputs 1.25VRMS, or thereabouts...I am going to measure it. The 0.6VRMS is because I run it at -6dB into the Placette because for some strange reason it sound...

Romy, I like many, would define streaming as the "live" playback of files (that you do not own) as they are streamed from the internet. Youtube is streaming, the Tidal app is streaming.
I would call playback from f...

But I need gain for most of my sources apart from perhaps the FM ...

[quote user="Paul S"]While I've hardly gone out of my way to learn more about streaming digital, the reason for that is the consistently mediocre results in my experience. Really, how does one rate and build on streaming digital in musical terms? So...

[quote user="Romy the Cat"] The “expedited” sound
shorten a bit the decay time/volume and makes transients more prevailing. This
is what very commonly audio people feel as “quality” but I degree with it.
[/quote]Romy, in my previous response I ...

Romy, I will attempt to fill you in on some backstory.
My Placette was purchased from a guy in France. My dac is made in the Netherlands. To an Australian that is just like next door. I have a good and strong rel...
|
|
[quote user="Romy the Cat"]Still, I feel that methodologically it is not right
way to build a playback. [/quote]No disagreement from me on this point. This is all just a thought bubble for now. Even if I wanted to press go on this project based ...
|
|
So, I have been looking into suitable valves to base a preamplifer around that are suitable for driving the DSET's. The pre must have a broad bandwidth, low output impedance, some current drive, and not be prone too easily to microphony. Oh, and pr...

[quote user="Romy the Cat"] Oh, good, why did not you tall it before. How the hell can
you listen if it you DAC outputs 1V?! No wonder you have no volume. Also if you
have no voluble you do not “get” one of the most advanced feature of multi-amp ...

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="rowuk"]How many sources do you currently have? If you are building a phono corrector, make it for 4 volts output. If you have a PC for digital playback, there are good DACs with more than 2V output. That would leave a tuner to pimp - cer...

[quote user="Romy the Cat"]
I do not know why Placette
does not work in your situation. You do not have enough volume? If it is the
case then you might have too low gains in your front end. All my front ends
have very high gain: Bidat, Lavry, my...

Hi Romy,Just thinking out loud here, but I have been listening to my mono DSET/Macondo for quite a while now and recently changed back to my old acoustic system so that I could poke around in the DSET innards for a little while. The old system (in s...

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...
