Any computer does absolute the same level of universality by being a digital file player. My telephone does it but I do not call my telephone a “digital transport”. Ripping CD it is not what your devise does but the fr...

[quote user="Paul S"]N-Set, why would you disconnect from the house neutral, unless you are using battery power??? This "neutral" is the "ground" leg of your circuit! The house neutral wire is typically white, and the house ground wire is typically g...

[quote user="steverino"]FWIW I got my own PP 1050 a week ago and am pleased with the sound. It is the first active device that sounds as good as or better than my jury rigged passive filtration. Thanks Romy. As for chaining devices, I tried plugging ...

[quote user="scooter"] Indeed, this is a reference to how important electricity might be. After last night, I almost feel as though my equipment is a much less important factor and takes a backseat to everything else. At this stage, I am thinking...

Here is another, simplified assault after some rethink and PSUD simulations.Rectifier: 3x1.2kV SiC per phase should do the job, actually 2 would do, but I'd preferto be safe. Bridge I don't want, as there would be 6 not 3 diodes switching1750V. 1.2kV...

Beinum recorded the Bruckner 8 in 1955 twice, in April and In June. My comment above goes for June recording.
There is something else I would like to add in context to Beinum 55 vs. Lubeck’s Wand.
The Lubeck’s Wand to me is still the ultim...

Twogoodears,
I am sorry, I do not know what you mean asking me to speculate on these pictures. I know very little about ALE drivers and I would not make any guesses. The system design that is presented on the picture is certainly not of my li...

In the world or audio you

I think this post need to have an epigrapher:
“We knew what we wanted to hear, and so we developped, and developped, and developped... In hundreds of small and bigger steps. Over thirty years. Till we were "there" where we always wanted ...

This is very interesting subject that gave me a lot of head ache until I figured the things out.
It is known that I have aversion to ground that comes with mains. It is very dirty, so a few years back I drove 15 feet copper poll in pretreated backya...

I got few inspirations recently that made me to dedicate today for building another DH MF for second amp. It is end of the day and the conversion of the second amp is done, including the PS, marking and drilling the holes, driver stage and the DH...

Rob and Romy the Cat,Thank you for inviting me to discuss this subject. Allow me to reply only to the main points raised, due to the present overload of work. However I will try to answer, later, to any specific question on the subject. First : - My ...

Ari,
I do not think that we recognize the process of “audio designing” as the identical actively. It looks as you peruse to design an amplifier (for instance) as a conceptually well operating system where a set of deferential abstractly-measurable v...

[quote user="darkmoebius"]I asked Jim Hagerman how long it takes to break in interconnects, power cords, speaker, cables, and preamps? He replied - "Usually about 40-50 hours on a FryK. The amps are fastest and get most of the way overnig...

It is interesting: I am running now Zarathustra amp with my woofer towers, line-level crossed at 90Hz with fist order. Everything is very fine bass-wise, with very minute touch of dominating smoothness. To my surprise the typical upper-bass har...

This subject of digital crossovers became quite popular during last few years and many audio-people give up and go for a simplicity and painlessness of digital crossovering. There is an army of people out there who would swear by a complete transpare...

One of the greatest and the most important things for me in power amplifiers is their ability to differentiate tones. When you listen live music you practically never hear two identical tones. Even two identical pitches presented after the diff...

Well, I finally found and implemented a digital front end that I can live with. I have been so cynical about digital up to now that I have kept and used an old, cheap Sony player (albeit one actually made in Japan...) because up to now it seeme...

[quote user="hagtech"]Yes, steel chassis can be both good and bad. It likes to conduct magnetic fields, so you have to treat things appropriately. A little spacing under a choke can go a long way. Otherise you have a 120Hz motor.&nb...

I mean to make this post with the observations for a number of weeks. The days are passing by and I hoped that I might get deeper to the bottom of it. Unfortunately I was not able to.
