Amir,you have now posted twice that "proper" USB is better than SPDIF. The problem is that it isn't, unless someone makes up rules to define their own sense of better. The problem here is that they have not defined anything that is better. Both metho...

[quote user="Romy the Cat"]fiogf49gjkf0dItem, you are not getting the point that ripping implied the initial read of CD by CD-ROM drive and their possess looks like kills the quality of the file you made on your “super PC”. If you imply that your PC ...

[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...

Does anyone really have the resources, and the patience, and the evolved audio/musical discrimination to develop a 4 or 5-way FR speaker system from scratch, including each and every driver? I can actually see a "theoretical" benefit in using field ...

Murat,
I was looking at your midbass horn design and I am wondering, how are you planning to time align that long midbass with the rest of the channels that seem to be time aligned. I mean, currently the midbass is phys...

Had some fun experimenting with 6e5p driver stage.playing with difrent output transformrs and resistors found that the stage can drive a speaker with ground connected to air. mabye this is widley know i did not know. + of speaker connected to bad ou...

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...

[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...

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...

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...

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 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...

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

[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 ...

hi romy,i like fm. and i like comparing different tunas. in the past ten years, i have bought and sold at least a hundred different tunas. i presently have more than thirty. easily 90% of my music listening is fm, even in the ...

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 ...

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 ...

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?...

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...

One of the ways to drag the REL tuner in the realm of civilized sound is to get rid of any crap that it has after its detector. One of the first things is to replace the 60 years old Germanium diodes with contemporary ultra fast and ultra low capacit...

JP, that are funny settings. You source the clock from AES line but do lock it. I do not know at what rate you record but you’re A/D looks like output 88K, you card read 44K and it is not locked – a complete mess. Call ...

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

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...

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...

I not juts actively hate this configuration but also actively abhor the rational that made people go for this direction.
The Morons use horrible power amplifiers and sonically impotent speakers and suffer from harsh and cruel Sound. Instead of tras...
