Last night and this morning I have been comparing my favourite SS preamp with gain and the breadboarded 10y. I've been using my dac with its low 1.125Vrms voltage output as the source because I know what it is capable of and know its (lack of) sound...
|
Over 10 year later, I finally "finished" and installed a shielded version of the above cable for the short run between my phono SUT and my phono stage, replacing the nondescript Placette cables I've been using there all this time. As anyone experien...

Hello, would it be possible for us to see the diagrams and schematics behind the Zarathustra II in the same spirit as the Melquiades was conceived, noting that the best of ideas are formed with the purest of sentiments?[quote]It is Dima’s and my stro...

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="anthony"]My preferred source is a Phasure NOS1a G3 dac.
The thing has no discernible sound of it's own. It outputs 1.25VRMS SE
and I run it at -6dB because it needs a little attenuation to sound its best
which means 0.625VRMS. I d...

...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...
|
[quote user="miab"]I have not seen it mentioned but I might of missed it. The PurePower absolutely demands shielded interconnects especially between preamp and amp in my experience. No matter how careful I route the cables, I was getting noise or buz...

I've played with this a little. We are 230V in Australia but many years ago the standard was 240V and the power coming into our house is still a nominal 240V. I remember playing with the Placette with a step down transformer and was not getting...
|
did you (or anybody else ) by any chance try Erno Borbely discrete op-amp based buffers? They are J-fet based kits from EU , not as expensive as Placette but not quite cheap either . Regards, L...
|
I have had a Placette Active for some 5 years now and it was quite a revelation when I put it in my system. According to Guy Hamel one of its most important features is its powerful op-amp output stage with an output impedance of 10 ohms. Since I hav...
|
Oh well sorry for the false lead, you are probably right that there was just something falty in my 300B but at least I found an amp that I really like.Since i have two outputs on my preamp(placette) maybe i'll look around for a cheap flea-power tube ...
|
Romy, would you say that placette is especially sensitive to electricity to function at it's best(sensitive in relation to other equipment I mean)? My unit is 110v and I am in 220v world, so I am using a step-down transformer on the unit. I have had...
|
Hi Rony, I assume you're stepping down to 110v at 50hz. I specifically asked Guy about this issue for a move to Europe. While Guy may be ok with the unit running at 50hz but I am not entirely convinced that the Placette runs the same versus the 60hz ...
|
Romy, have you been able to gather any thoughts yet about the new "bad-AC-proof" power supply?If yours is actually bad-AC-proof and still sounds just as good or better than the "crappy little PS" with good AC then it will be good news.Do I ...
|
[quote user="Romy the Cat"] Yes, I have thought about it. My Placette has no tape loop but I think it needs to be added. It is shame that I did not think about it before – it would save me some cable not to mention an ability to run A/D from anyt...
|
Hi Romy,I have listened to one of these alot recently although unfortunately I don't own one!http://www.dejavuaudio.com/PREAMPS-KONDO-KSL-M77.HTMI'm sure you wouldn't enjoy it at all but others might and ought to try to at least hear one if they have...
|
Hi Alex,Short of waving goodbye to the Bidat for a few months, you could always TRY the splitter idea from your favorite cable guy. It may be acceptable enough for your needs.Did you mean there is no space on the back of your passive/relay base...
|
While the APS guys trying to figure out why this unit can not handle power (which more likely involved a phone call to China :-) I decided to give another try across everything, repeating my last listening, this time in relaxed environment with diffe...
|
I got toady the preamp from Guy Hammel. Oh, boy, I did not expect that it will be so interesting.
The initial idea was very moderate to add more inputs to my preamp. We ended up with adding 5 inputs extra input, so I have 11 all together – eventuall...
|
...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...

There seems to be a standard 2.7V option for you:http://www.phasure.com/index.php?PHPSESSID=rdq01o6tv8ed20nii15hjqnjb0&topic=1560.0"Output level for Single Ended Mode (RCA) is 1.5VRMS (-3dBFS relative to normal Full Scale). Output level for Diffe...
|
Anthony, congrats on your amazing progress! I know how hard it is to carve out time for this stuff! I see you are looking for gain from your pre-amp, which makes me wonder if you have been using the passive Placette, as opposed to the active unit, wh...
|
Steverino, don't forget that Romy's Placette line stage has VERY low output impedance. It might be able to handle even the shunt capacitance of 75 feet of cable with minimal HF losses. If the cable is 100 pF/foot then its reactive impedance is abou...
|
If you want to keep it really simple just buy an Oppo BDP-83SE ($800) and use its two-channel audio analog outs to an amp with volume controls. All the setup features you need are in the Oppo including the downmix to 2.0.A new projector will run you ...
|
Steradian,
I do not remember how much input impedance of my Placette is. I think I did ask to make it higher then 18K but I do not remember now, can measure if I were home…. In most of the cases the 18K is plenty but it very easily could be in...
|
I lost all hope for horn loaded Lowther speakers . Got Phile Mikey (fremmer) recommended TT and new old MC cartrige (benz Mc3) so analong front sounds comparable to old modded MCintosh CD player I have. I finished (took al ong time ) Hagerman c...
|
I have been surprised that you have not already pursued the Zarathustra for your multi-driver, sealed LF. From your early descriptions of both, this seemed like a natural pairing and the most likely way to go, to keep the drivers "off the ...
|
Maybe you already said it and I am just too tired to follow, but does the APS do OK with "component interaction"? This has been another problem for me, where the thing does alright with one front end component but gets worse with two or more, a...
|
I also got tired of reading all the DIY posts on the S&B 102. And yes, I have done the numbers, and it would be possible to adversly affect bass with high impedance feeds and/or long, bad cables feeding this unit, coupled to ...
|
I asked Guy Hummel to put a headphones jack into my new unit. Guy put the jack, the switch that redirect signal to headphone or to the main output. It is so cool to have a headphone option – I have no idea why I did not ask him to do it before. In ad...
