I would like to post it into this thread, as somebody who cares about S2 should know what I ended up.
Anyhow, now it is officially: I permanently removed a tweeter from Macondo. The properly voiced S2 driver (with a transparent enough track- h...

[quote user="gurevise"]Ideally, you'd want to drive 35 feet of balanced interconnect with the low impedance source ( say below 150 ohms or so). How low depends upon interconnect capacitance. You can try Jensen output transformer to convert SE to Bala...

[quote user="N-set"]... I cannot imagine where the fuck I should have a loop??? [/quote] And you are not alone. Any single person who is chasing noise in phonostage ask himself the same question. I assure you that sun of later you will find it and it...

I think that any line level tube stage can be every much of an expressive tool as any other device in the chain. I am also not sure that the biggest difference between digital and analog is the sampling process.How "transparent" is a cutting lathe or...

If the high ac voltage of the Melquiades amp is what allows it to operate with the same coupling cap that doesn't work with the buffer, perhaps there is some hysteresis going on in the capacitor. In that case I think it may help to use a smaller cou...

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...

Hm you are true in the “terra incognita” territory as far as I concern. The preamps are mystery to me. All my attempts to make any decently sounding preamp or even buffer failed. To me Placette was truly God sent and if I got burned that I am looking...

It is true that a given battery will have "special" requirements for optimal charging. Also, where the battery is in a circuit and the specific demands of use can influence how and/or how quickly it "wants to be charged", not to mention different ba...

[quote user="Paul S"]It surprises me if you wish to do away with the battery. Or, perhaps a unit could be offered "less battery", which the purchaser/user could add on his/her own. This would "solve" the logistical problems (and the expense) of shchl...

Ronnie,I do not know any. But the major question is why such a crossover is necessary. Obviously it requires 3 amplifiers and if so then the filters might be built in the amps. It one needs it for system prototyping purpose then if is fine but the de...

I am not sure I follow the TV analogy...I think that the best course where any sort of voltage divider/attenuator is concerned is to do it without messing up the audible results, of course, but also to keep it as "neutral", "transparant" an...

Erik, I do not think a resistor in series would do as it will burn on itself some voltage and the coil will be driven by the same voltages. It would be good to put in place of the resistor a rheostat and to slide it up and down while slide up and dow...

then the idea of amp bypassing is relevant to the "clean signal" discussion. But regardless of the measured voltage out vs. driver sensitivity I suspect that there is too little of something in the way of drive and control between a&n...

I am with you on this one. I am also very suspicious of gigantic, 4-chassis phono stages if only because I just wonder why the need for all those damn noisy parts, along with concommitment connections?So it really pisses me off to admit that th...

I was reading the Stefano Bertoncello's post about his new multi-amping again options.

.. and I feel that it would be a good idea to brief summarize multi-amping cros...

Do you REALLY need one?
Why SHOULD you need one?
A buffer is "simply" a device for converting impedance from high to low to drive cables but every such device loses information in the process.
With a 47R ouput impedance surely your Bidat has ...

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 ...

[quote user="Bud"]I am about 3 weeks away from supplying 3 Kz ohm to 4,8 & 16 ohm SE outputs for 300b or 2A3 tubes to George Wright, of Wright Sound, and Gary Pimm of Pimm CCS fame (constant current controls to buffer stages from each other ...

Chris,
The point of digital delay is well taken. Digital has no problems to delay and if someone had only digital as source then it is very simple to use tow parallel DACs and to stick temporary storage memory in one or them. In case of multiple so...

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, fully buffered 10R out?...

An interesting amp, thanks, decoud. http://www.sacthailand.com/AmpGlowMasterGM70.htmlI never have seen or hear it but it might be interesting. Chinese makes nowadays a lot of pretentious high-end products and they are mostly horrible crap. Here is Th...

I had a chance to listen to/for the Einstein components at THE Show, but there seemed to be no reason to pay attention to them, since they neither disappeared nor did they transform the sound in any remarkable way. My overall impression was that the...

rather discussing a potential of building a tube buffer around 801/10. I'd appreciate your help very much, especially your sound impressions under various conditions. My mail phixphi_AT_gmail.com

In your earlier piece about how to use the S2 'properly' you wrote"Whatever happens between the 400 and 2,5 is pretty much unnecessary for you garbage. So, get any known to you soft capacitor of 3uF and place it in series with the S2 driver. This wil...

Well, you can go ahead and solder your wire-to-plug connections in the high-end AC cords, etc., but it is almost certain that the whole system up to that point uses screw terminal conections at best, and insanely and (dangerously!) cheap slip/frictio...

If the APS works as I described in the paragraph above then the buttery does not filter/buffer the source of ASP’s oscillator and amplifier. In this case I would like to get rid of the buttery and do not let the APS circ...
