A dog is much more like audio. In the beginning, it is not trained and pees and bites, jumps up - all sorts of primitive behaviour. BUT, unlike a cat and very much like Audio, it needs to and can be trained. In fact, a new dog MUST be controlled. It ...

The cap was only to block DC and is not required at this position. I think that Tim (the developer) removed it on later versions himself....

I also built one. It does not have enough gain for a low output MC cartridge. You need a step up transformer. I use an Ortofon T30....

Just think back a couple of years where you read about claims of difference in the sound of cables and wondered if it could be true. Well, in many cases it isn't and those posting document the BS by making claims that simply do not describe what cabl...

I am always a bit hesitant to buy into "listening descriptions". I am a musician and am confronted every day with Sound bias - attraction to what we are accustomed to, expectations being confirmed. We are creatures of habit and modifying old habits i...

I must be missing something - or not be ready for this yet. Here are my understanding problems:1) he starts with the "left" speaker and searches for the best bass. I would think that one should search individually with the left and right and pick the...

At dinner tonight, we had internet radio playing and a J.S. Bach Motet "Komm, Jesu komm" BWV229 came on. I stopped eating (my wife was not happy, fortunately this does not happen often). The reading was so complete, expressive, clean. Even although t...

The 834p is a tried and true circuit. It should be OK. If you have hum, I would suspect the step up transformers first and the power supply second. Maybe a ground lead is not attached?Take it completely out of the system, disconnect the phono leads, ...

I subscribe to the Digital Concert Hall and this showed up in my inbox today.
Now as a direct-to-disc LP: Bruckner's Seventh Symphony with Bernard Haitink

Maybe we could do something for the string or horn section of an orchestra as what reaches the microphone is very „random“ including early and late reflections. I would imagine problems however with instruments with less „random“ pickup: trumpets, tr...

The audiophools have a term PRaT: Pace, Rhythm and Timing that apply here - even if many do not understand that this is NOT something that makes you tap your toes to the banjo... Performing jazz musicians have a term "groove" that covers similar terr...

Actually, in the history of music, rhythm changes inside a phrase are not that old. Hugo Riemann coined the phrase Agogik (Agogics) in 1884 and the following things were included:accel. (accelerando) – accellerate - play increasingly fasterstring. (s...

I am a trumpet player and teach as well. For my trumpet "beginners", I have a standard repertoire of exercizes to develop their playing. In the beginning, we find the tones that they can easily produce and build from there. As soon as a minimum of "t...

How can we compare anything if we know from the very first note what media is being used? The noise floor and sonic artifacts are unique to each media, so are we talking about confirmation bias? Let us assume that we have a first generation analog ma...

Not that physics is my strong suit, but casually watching a physics youtube video this thought crossed my mind.
I wonder if gyroscopes can be used in a turntable to improve it's performance without reverting t...

I too am collecting thoughts about what "good enough" refers to in applied audio. I read a post elsewhere this morning that brought a new twist and maybe some depth.Let us assume that we successfully practice applied audio, have a proper system, well...

TH,Avoiding mistakes is something that we would like to do. It saves time and money BUT unfortunately the science of building loudspeakers is based on specs, not „Tone“ or „Sound“. Being an engineer can help make beautiful drawings but we all learn t...

Thorsten Loesch who came up with the mods, details what caps and why on the first page of this thread. Lacking interest for multiple years of auditioning caps, I just built it that way (2012 or so) and have had no urge to change anything. Romy has pi...

TH,this is very much NOT a DIY site. It is however probably the most complete collection of „SOUND as it is related to horns“ articles.I suggest that you check out things here first before asking „the wrong“ questions. The horn systems that you show ...

We cannot view theoretical advantages of individual parts as the path to a better solution. The EAR phono corrector worked so well because the total concept was holistic. Thorstens modifications did not use the "premiere" parts to get the total solut...

I find the fascination of boutique parts amusing. In the case of vintage tubes, using them is a guarantee that one day you will never be able to replace them. In my world, I want to optimize with „sensible“ parts, maybe even stockpile some extra tube...

I would maintain that much of the music available is intended for "informed audiences". This is true if we are listening to Stockhausen, Stravinsky - or mediocre concerts by amateurs or "semi professionals".The level of our preparation makes it easie...

The issue here is that quality and enjoyment are 2 different things. The former is absolute and the latter relative. Quality is a parameter, that in this case belongs to the orchestra. It can be defined by using measuring units of intonation, synchro...

The "tactile sensation" was during a live concert (multiple times) last weekend and reminded me of similar situations at other concerts. I had never thought about this effect for my playback and just decided that I would investigate it. As far as my ...

Well, I do have 3 channels of DSEP. Dedicated Single Ended Pentode: one channel (bass/mid 30-500 Hz) with a 307A DH pentode feeding two wonderful Fane neodymium Colossus 12" - one from FS to 150 Hz and the second from FS to 500 Hz. OPT with a lot of ...

We refer to playback singularly as an audio event as we have recorded sound waves with acoustic devices (microphones) and play them back through other acoustic devices (speakers/headphones). The basic rules of stereo are generally adhered to (phase a...

Paul, as this sensation also happens during performances without "bass pressure" (a solo lute or voice for instance), I am not even sure how to start looking. There is a part of real sound transmitted not processed by the ears, rather over the skin. ...

I am in the think through stage of improving my playback. Each loudspeaker currently has 2x 12" woofers in a sealed 80 liter cabinet (Fc-500 Hz). Measured LF extension is more or less flat to 30-35 Hz. Efficiency is close to 100dB/watt. The list...
