[quote user="cv"]Here's a crazy thought... have you every tried driving the S2 directly from the Placette?! I know the 6E5p does some unique things but I wonder if it might be educational.The placette has a 7 ohm Zout right? Don't forget that that do...

[quote user="Romy the Cat"]Again, it was very interesting, but… Let agree that methodologically you did not try Placette as it performance was masked out by you need to use your Neurochrome buffer to get gain. Your chain will sound as the worst eleme...

Ronny,
I moved your post to the Placette thread. I hope you do not mind.What I fine interesting in this subject is not that fact of Placette wonderful transparency - it a fact but that you (and I in past) were trying to challenge Placette with a tub...

Yes, the Active Placette would drive headphone, still I do not like the sound. I get way more proper sound when Placette driver my “big” system then what is drivers headphone. I use headphone quite aggressively but mostly for “technical listening” (l...

Latterly is have been some controversy with new Placette output impedance, it does not look like it is 3R but rather 37R according to my measurement. I need to clear it with Guy. I also desided to address (since the Active Placette is a discrete op-a...

[quote user="anthony"]Have put all my DHT's on the curve tracer to see if pairs can be matched for preamp duties. [/quote] It was very interesting to read about all of it. If you have a socket for YO186 then you can accommodate all 4V tubes and I si...

Just a brief note on my recent addition: Placette Active preamp. Due to a recent purchase of Tannoy Golds, I had the opportunity to pull an old McIntosh SS amp out of the closet recently. This amp has gain controls, so I tried running it ...

Hi Romy,I wish I had seen your post on Placette before buying mine. I didn't realize that there is no balance control on the unit. I know in theory this should not be a problem, but I miss this feature for several reasons. Can't hav...
|
|
Attentuators plugged directly into the RCA jacks sounds like good solution for balance control, though I will check Placette first for cost of adding second remote controlled sensor, thanks romy....

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...

|
[quote user="Romy"] I see a problem. Sine you have 8 meters interconnects I presume that it a relatively large room with speakers positioned relatively far. This way your common remote control will drive two Placette passive units located a few meter...

But I thought the core of the Placette is passive, with a buffered output, no gain?How could this work at all?Best regards,Paul S...
|
|
Hi Paul,My understanding is that the placette has a unity gain buffer. At full CD ouput levels of 2Vrms into an S2 - it wouldn't quite get that into the S2s 16 ohms - but say it did, you'd be looking at about 109db from a pair...I'm not saying it wou...

|
Romy, I am not clear why you would worry about DC if you can set the RC where you want it and mute input.Biggest problem, of course, is HF, since it takes bugger all to blow those ribbons. But I thought you had that variac that the Serb gave yo...

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...

OK, got the Placette from the second round of "modification", it took 15 second to confirm that the HF problems that I sniffed out was not there anymore – so the absolute transparency is back to the business and this time the word “absolute” could be...

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...

Once I've assumed my speakers system into this house won't ever be able to deliver what I wish to accomplish, I have kind of downgraded my exigences and I'm more and more listening to headphones. For the last few months I've been trying different hea...

That is truly great and IO would like to express one more time my esteem to active Placette preamp.
I play with 3 tuners and multiple stereo decoder options trying to gig out the minute differences and aspect of sound of those units. It is a pure an...

|
[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...

Rony,
Actually I did try to drive Melquiades from different source. My old tube buffer, my phonostage and any other not DC-coupled source were not able to drive it. The 6-ch Melquiades is pain in as to drive. It has around 5K input impedance ...
|

Glad to hear you finally went and did IT! Now let's see (hear) how buffered per-channel level-set resistance works with the per-channel curves, and how easy this is to tune and integrate per total (stereo) side. It seems like this pretty much "has t...
